| 472 | 40:21 | Here,plants have been forced to evolve very different strategies for survival. | 在这里，植物被迫进化出非常不同的生存策略。 | |
| 474 | 40:30 | And few are better adapted than the blue euphorbia. | 很少有比蓝色大戟更适合的了。 | |
| 475 | 40:33 | It's all about saving water. | 都是为了节约用水。 | |
| 476 | 40:38 | The euphorbia's branches grow vertically so when the sun is at its hottest,high in the sky, it strikes only their narrow tops, reducing water loss through evaporation. | 大戟的枝干是垂直生长的，所以当太阳处于最热的时候，高高的时候，它只会照射到它们狭窄的顶部，减少水分蒸发的损失。 | |
| 480 | 40:54 | Their branches also store a large amount of fluid in the form of a milky sap. | 它们的枝条也以乳白色树液的形式储存大量液体。 | |
| 482 | 40:59 | This liquid reservoir is poisonous and unpalatable to most animals, saving the plant from damage caused by feeding. | 这种液体贮存器对大多数动物有毒且不适口，使植物免受取食造成的损害。 | |
| 485 | 41:17 | The Shepherd's tree takes a less conservative approach to life in its dry environment. | 在干燥的环境中，牧羊树的生活方式不那么保守。 | |
| 487 | 41:23 | It sends roots deep into the ground, reaching reserves other plants can't. | 它把根深深地扎进地下，到达其他植物无法到达的地方。 | |
| 489 | 41:34 | Instead of saving that water like the euphorbia, it immediately uses it to grow dense,nutritious leaves and berries, a rare food source for the animals living in the Thirstlands. | 它没有像大戟那样节约用水，而是立即用它来生长茂密、营养丰富的叶子和浆果，这是生活在干旱地区的动物的稀有食物来源。 | |
| 494 | 41:46 | Those animals then spread the tree's seed across the countryside, ensuring the survival of the species. | 这些动物随后将树的种子传播到乡村，确保了物种的生存。 | |

| 501 | 42:26 | This male's herd numbers only five, and they still struggle to find all they need. | 这只雄性的兽群只有五只，它们仍然在努力寻找它们所需要的一切。 | |
| 503 | 42:38 | Mares have been known to fatally injure the foals of others to reduce competition for their own young, a seemingly cruel characteristic evolved for survival under the harshest conditions. | 众所周知，母马会致命地伤害他人的小马驹，以减少对自己幼崽的竞争，这一看似残酷的特征是为了在最恶劣的条件下生存而进化出来的。 | |
| 507 | 42:55 | And even Addo's most devoted parents cannot always protect their vulnerable offspring. | 即使是阿多最忠诚的父母也不能总是保护他们脆弱的后代。 | |
| 509 | 43:13 | After almost two days guarding her dead calf, the young mother has no choice but to leave. | 在看护她死去的小牛犊将近两天后，年轻的母亲别无选择，只好离开。 | |
| 511 | 43:23 | Exhausted and starving, she is driven to eat and drink for her own survival. | 她筋疲力尽，饥肠辘辘，为了生存，她被迫吃喝。 | |
| 513 | 43:34 | Elephants are known to have long memories, so we cannot tell how long the trauma of her loss will last. | 众所周知，大象有很长的记忆，所以我们无法判断失去大象的创伤会持续多久。 | |
| 516 | 43:45 | But the chances are high that she will bear another calf. | 但她很有可能再产一头小牛。 | |
| 517 | 43:48 | Sooner or later,the experience of death will be replaced by the joy of new life. | 死亡的体验迟早会被新生命的喜悦所取代。 | |
| 519 | 43:58 | Elephants normally give birth every five years, but having lost her young calf, she will come into estrus sooner. | 大象通常每五年生产一次，但由于失去了幼崽，她会很快进入发情期。 | |
| 522 | 44:05 | Once pregnant, she should give birth again in just under two years. | 一旦怀孕，她应该在不到两年的时间内再次生育。 | |

| 397 | 35:46 | Unlike ghost frogs, table mountain's extreme specialist, the secret of this chameleon's success is its adaptability - it can survive everywhere from fynbos and forest to urban gardens. | 不像幽灵蛙，桌山的极端专家，这变色龙的成功秘诀是它的适应性-它可以生存在任何地方从fynbos和森林到城市花园。 | |
| 401 | 36:04 | Large individuals such as this one can grow up to 7 inches in length. | 像这样的大型个体可以长到7英寸长。 | |

| 430 | 39:34 | Ironically the burnt landscape is perfect for new seedlings. | 具有讽刺意味的是，被烧毁的景观非常适合新的幼苗生长。 | |
| 431 | 39:36 | With the dominant adult plants gone, there is no competition for space or water. | 随着占优势的成年植物的消失，没有空间和水的竞争。 | |
| 433 | 39:45 | And the nutrients once stored in living vegetation now lie as highly fertile ash on the ground. | 曾经储存在活植物中的营养物质现在像肥沃的灰烬一样躺在地上。 | |
| 435 | 39:53 | Like a phoenix rising from the ashes, fynbos is reborn after each fire. | 就像一只从灰烬中升起的凤凰，fynbos在每一场火灾后都会重生。 | |

| 467 | 43:21 | Shellfish are an incredible source of protein. | 贝类是一种难以置信的蛋白质来源。 | |
| 468 | 43:29 | These baboons spend only about 5 percent of their time feasting at the shore, but the nutrition they gain is invaluable. | 这些狒狒只有5%的时间在岸边享用美食，但它们获得的营养却是无价的。 | |
| 471 | 43:39 | It is thought that this same protein source also helped fuel human development hundreds of thousands of years ago. | 人们认为，这种同样的蛋白质来源在几十万年前也促进了人类的发展。 | |

| 9 | 00:51 | Known locally as "The Miracle," due to its beauty, this is the magical world of iSimangaliso. | 当地人称之为“奇迹”，由于其美丽，这是伊西曼加里索的神奇世界。 | |
| 11 | 01:32 | These remote shores lie nestled between an ancient forest and the Indian ocean. | 这些偏远的海岸坐落在古老的森林和印度洋之间。 | |
| 13 | 01:43 | They are beautiful yet unpredictable. | 它们美丽而不可预测。 | |

| 15 | 02:08 | But tonight they have a visitor. | 但今晚他们有客人。 | |
| 16 | 02:25 | A female loggerhead turtle hauls herself onto the shores of iSimangaliso's Bhanga Nek coastline. | 一只雌性红海龟拖着自己来到伊西曼加里索的邦加内克海岸线上。 | |
| 18 | 02:35 | She has traveled the world's oceans to return to this exact spot: the same beach where she was born. | 她游历了世界的海洋，回到了这个确切的地点：她出生的同一个海滩。 | |
| 20 | 02:45 | This is one of the few times in her life she will come onto land. | 这是她一生中为数不多的几次登陆。 | |
| 22 | 02:55 | And she is here for one special reason: to start the next generation. | 她来到这里有一个特殊的原因：为了开创下一代。 | |
| 24 | 03:12 | She slowly digs a nest three feet deep in the sand with her huge flippers. | 她用巨大的鳍状肢在沙滩上慢慢地挖了一个三英尺深的窝。 | |
| 26 | 03:19 | This isn't an easy task. | 这不是一件容易的事。 | |
| 27 | 03:21 | She's out of her element, exhausted and at her most vulnerable. | 她已经不适应环境了，精疲力尽，处于最脆弱的状态。 | |
| 29 | 03:39 | But her whole life has lead to this moment. | 但她的一生都导致了这一刻。 | |
| 30 | 04:10 | She slowly lays around 100 eggs in the nest. | 她慢慢地在巢里产下大约100个蛋。 | |
| 31 | 04:19 | She will be lucky if ten survive. | 如果有十个人活下来，她会很幸运的。 | |
| 32 | 04:29 | The sex of her hatchlings will be determined by how deep she buries her eggs. | 她的幼仔性别将由她埋卵的深度决定。 | |
| 34 | 04:37 | The temperature in loggerhead turtle nests ranges from 79 to 90 degrees Fahrenheit. | 红海龟巢穴的温度在79到90华氏度之间。 | |
| 36 | 04:47 | Eggs that are incubated in cool conditions become males. | 在低温条件下孵化的卵变成雄性。 | |
| 37 | 04:56 | Those that develop at higher temperatures become females. | 那些在较高温度下发育的成为雌性。 | |
| 38 | 05:06 | The process is long and arduous,taking hours to complete. | 这个过程漫长而艰巨，需要数小时才能完成。 | |
| 39 | 05:19 | When she has finished laying, she covers her eggs with sand and returns to the sea. | 当她产完蛋后，她用沙子覆盖她的蛋，然后返回大海。 | |

| 42 | 05:45 | Her job is done. | 她的工作完成了。 | |
| 43 | 05:53 | There is a reason why she swam great distances to return to this coastline. | 她游很远的距离回到这条海岸线是有原因的。 | |
| 45 | 06:03 | It's because of the sand at the base of the dunes. | 是因为沙丘底部的沙子。 | |
| 46 | 06:08 | They're full of titanium ore,which heats up under the sun, turning the sand into the perfect egg incubator. | 它们充满了钛矿石，在阳光下加热，把沙子变成了完美的鸡蛋孵化器。 | |
| 48 | 06:20 | Titanium ore is also a hydrophilic agent, meaning it attracts water, ensuring the turtle eggs never dry out. | 钛矿石也是一种亲水剂，这意味着它能吸引水，确保海龟蛋永远不会变干。 | |
| 51 | 06:31 | This isn't only crucial for loggerhead turtles, it's vital for the whole wetland. | 这不仅对红海龟至关重要，对整个湿地也至关重要。 | |
| 53 | 06:40 | When it rains,water draining through the sand is drawn to the titanium, which slows,the passing of moisture through the water table. | 当下雨时，通过沙子排出的水被吸引到钛上，钛减慢了水分通过地下水位的速度。 | |
| 57 | 06:55 | As a result,the dunes store huge amounts of rainwater, which slowly seeps out, nurturing the surrounding forest. | 因此，沙丘储存了大量的雨水，这些雨水慢慢渗出，滋养了周围的森林。 | |
| 60 | 07:05 | These are some of the largest and oldest forested dunes in the world. | 这些是世界上最大最古老的森林沙丘。 | |
| 62 | 07:13 | They form the eastern border of South Africa's first World Heritage Site and most spectacular wetland park. iSimangaliso,the Zulu word for miracle, so named for its beauty and the miraculous abundance of life found within its borders. | 它们构成了南非第一个世界遗产和最壮观的湿地公园的东部边界。iSimangaliso，祖鲁语中的“奇迹”一词，因其美丽和在其境内发现的奇迹般丰富的生命而得名。 | |
| 67 | 07:39 | Eight interlinking ecosystems, three major lakes, and South Africa's most pristine estuary form the heritage site. iSimangaliso combines dry savannah and sumptuous reefs; dense coastal forests and untainted estuaries. | 八个相互联系的生态系统、三个主要湖泊和南非最原始的河口构成了遗产地。iSimangaliso结合了干燥的热带草原和奢华的珊瑚礁；茂密的海岸森林和未受污染的河口。 | |
| 74 | 08:12 | This incredible mix of habitats supports a wealth of wildlife. | 这种令人难以置信的混合栖息地支持着丰富的野生动物。 | |

| 84 | 09:00 | (screeching) | （尖叫） | |
| 85 | 09:15 | Samango monkeys are South Africa's only exclusively forest dwelling primate. | 萨曼戈猴子是南非唯一的森林灵长类动物。 | |
| 87 | 09:27 | They're arboreal,which means they live almost entirely among the trees and spend very little time on the ground. | 它们是树栖动物，这意味着它们几乎完全生活在树中间，在地上的时间很少。 | |
| 89 | 09:39 | They don't like strong sunlight and seek shelter among branches and leaves. | 他们不喜欢强烈的阳光，在枝叶间寻求庇护。 | |
| 91 | 09:52 | Their diet is largely made up of fruit,leaves,insects,and fungi. | 他们的饮食主要由水果、树叶、昆虫和真菌组成。 | |
| 93 | 10:01 | And they have their favorites. | 他们有自己的最爱。 | |
| 94 | 10:11 | They depend on the rich diversity of flora found in Bhanga Nek. | 它们依赖于班加内克植物区系的丰富多样性。 | |
| 96 | 10:22 | As a result,this dune forest in iSimangaliso is one of the few in the world that can support them. | 因此，伊西曼加利索的这片沙丘森林是世界上为数不多的能够支撑它们的森林之一。 | |
| 98 | 10:35 | Samango monkey troops are like one large family. | 萨曼戈猴子部队就像一个大家庭。 | |
| 99 | 10:42 | The females in the troop provide guidance for the young. | 部队中的女性为年轻人提供指导。 | |
| 100 | 10:50 | They start learning how to survive in the forest from when they are just a few weeks old. | 他们从几周大的时候就开始学习如何在森林中生存。 | |
| 102 | 11:01 | Youngsters learn how to eat,climb,and groom by watching their mothers. | 年轻人通过观察母亲来学习如何进食、攀爬和打扮。 | |
| 104 | 11:11 | When monkeys groom each other, it releases endorphins in their brains. | 当猴子互相梳洗时，大脑会释放内啡肽。 | |
| 106 | 11:20 | Endorphins are the happiness chemical-- and they are addictive. | 内啡肽是一种快乐的化学物质，它们会使人上瘾。 | |
| 108 | 11:30 | Most monkeys spend up to 20% of their day grooming. | 大多数猴子一天中有20%的时间用来梳理毛发。 | |
| 109 | 11:35 | The rest is spent traveling and foraging. | 其余的花在旅行和觅食上。 | |
| 110 | 11:44 | By watching and learning from her mother, this juvenile will one day pass on what she has learned to her own children. | 通过观察和向母亲学习，这个孩子总有一天会把她学到的东西传给自己的孩子。 | |
| 113 | 12:00 | The young become independent after a couple of months, but continue to nurse for another two years. | 孩子们几个月后就独立了，但还要继续护理两年。 | |
| 115 | 12:10 | (screeching) | （尖叫） | |
| 116 | 12:12 | But not every animal in iSimangaliso has such a rich childhood. | 但并不是每一种动物都有如此丰富的童年。 | |
| 118 | 12:21 | A very different approach to rearing young can be found further inland,in the center of the park. | 在更远的内陆，在公园的中心，可以找到一种非常不同的育儿方法。 | |
| 120 | 12:33 | Spanning over 115 square miles, St.Lucia is the largest marine lake system in Africa. | 面积超过115平方英里，圣卢西亚是非洲最大的海洋湖泊系统。 | |
| 122 | 12:43 | Five rivers flow into it. | 五条河流汇入其中。 | |
| 123 | 12:49 | (thunder cracking) | （雷声劈啪） | |
| 124 | 12:53 | When the rains are good,the flow of fresh river water lowers the lake's salt content. | 雨水充足时，河水的流动会降低湖水的含盐量。 | |
| 126 | 13:03 | But when the rains dry up,the rivers stop flowing and the level of the lake can drop below the sea. | 但是当雨水干涸时，河流停止流动，湖水的水位会下降到海平面以下。 | |
| 128 | 13:13 | When this happens,seawater flows in to replace the lost fresh water,producing a salt content that can be three times higher than the ocean. | 当这种情况发生时，海水流入以补充流失的淡水，产生的含盐量可能是海洋的三倍。 | |
| 131 | 13:28 | Animals that can't cope with this much salt perish. | 不能忍受这么多盐的动物会死亡。 | |
| 132 | 13:33 | But others adapt. | 但其他人适应了。 | |
| 133 | 13:42 | Like a small fish that has an intriguing way of coping with excess salt. | 就像一条小鱼，它有一种有趣的方法来对付过量的盐。 | |
| 135 | 13:53 | The tilapia is able to change the workings of its gills to match the salinity of the surrounding water. | 罗非鱼能够改变鳃的运作方式以适应周围海水的盐度。 | |
| 137 | 14:01 | Gills are the organs through which fish extract oxygen from water. | 鳃是鱼从水中提取氧气的器官。 | |
| 139 | 14:11 | In freshwater fish,gills work to retain the salt; in saltwater fish,they expel it. | 在淡水鱼中，鳃的作用是保留盐分；在咸水鱼中，鳃会排出盐分。 | |
| 141 | 14:20 | But the tilapia has the unique ability to adjust the receptors in its gills to match its habitat. | 但是罗非鱼有独特的能力来调节鳃中的受体以适应其栖息地。 | |
| 143 | 14:29 | As a result,it is just as happy in both salt and fresh water. | 因此，无论是在盐里还是在淡水里，它都同样快乐。 | |
| 144 | 14:42 | But even for the tilapia,life in St.Lucia is difficult. | 但即使对罗非鱼来说圣卢西亚这很难。 | |
| 145 | 14:46 | They may not have to worry about the changes in salt levels, but they do have to worry about these. | 他们可能不必担心盐含量的变化，但他们确实需要担心这些。 | |

| 154 | 15:49 | And they've adapted to living here in an inventive and unexpected way They make burrows. | 他们已经适应了这里的生活，以一种创造性和意想不到的方式，他们打洞。 | |
| 157 | 16:06 | When water is scarce,the crocodiles dig large holes into the riverbanks. | 缺水时，鳄鱼会在河岸上挖大洞。 | |
| 159 | 16:12 | By burrowing down through the water table, they are able to access beds of fresh water other animals can't tap into. | 通过钻入地下水位，它们可以获得其他动物无法进入的淡水床。 | |
| 162 | 16:21 | They have been doing this for generations. | 他们已经这样做了好几代了。 | |
| 163 | 16:26 | But unlike samango monkeys, childhood for iSimangaliso's crocodiles is not a time of nurturing or learning. | 但与萨曼戈猴子不同的是，伊西曼加利索鳄鱼的童年不是一个养育或学习的时期。 | |
| 166 | 16:38 | From the day it was born,this baby has been on its own. | 从它出生的那一天起，这个婴儿就靠自己了。 | |
| 167 | 16:44 | Left to fend for itself, it hasn't been taught what to eat or how to survive. | 任由它自生自灭，它还没有学会吃什么或如何生存。 | |
| 169 | 16:56 | It's also had to face a constant threat from hungry birds and the ever-changing water. | 它还必须面对来自饥饿的鸟类和不断变化的水的持续威胁。 | |
| 171 | 17:08 | But the ever-resilient crocodile is full of surprises. | 但是，这条有弹性的鳄鱼充满了惊喜。 | |

| 197 | 20:19 | They lose water up to five times quicker than humans. | 它们失水的速度是人类的五倍。 | |
| 198 | 20:21 | This is because they have a thick skin, but no sebaceous glands-- the glands responsible for regulating temperature. | 这是因为它们的皮肤很厚，但没有皮脂腺——负责调节温度的腺体。 | |
| 201 | 20:36 | Because of this,hippos rely on water to keep them cool. | 正因为如此，河马依靠水来保持凉爽。 | |

| 216 | 22:00 | The majority of the hippo's activities take place in water-- including mating. | 河马的大部分活动都发生在水中——包括交配。 | |
| 218 | 22:14 | Conception usually happens during the dry season, so that births may coincide with the rains. | 受孕通常发生在旱季，因此分娩可能与降雨同时发生。 | |

| 80 | 07:40 | They're mainly vegetarian,although they will eat insects on occasion. | 他们主要是素食主义者，尽管有时会吃昆虫。 | |
| 81 | 07:44 | But in the arid Karoo, acacias deter herbivores from eating their precious leaves with thorns and the Vervets need to be nimble enough to negotiate the formidable thorny defenses these are the only trees in the park. | 但是在干旱的卡鲁，金合欢树阻止食草动物吃掉它们的带刺的珍贵叶子，而维维特树需要足够的灵活来应对可怕的带刺防御——它们是公园里唯一的树木。 | |
| 85 | 08:07 | They're highly social and young learn from their parents and babysitters. | 他们是高度社会化和年轻的学习从他们的父母和保姆。 | |
| 86 | 08:10 | Like many primates,mothers often hand over the responsibility of caring for babies to relatives. | 像许多灵长类动物一样，母亲经常把照顾婴儿的责任交给亲戚。 | |
| 88 | 08:18 | This allows her to have her next baby sooner. | 这样她就可以早点生下一个孩子。 | |

| 99 | 09:45 | Where there are herbivores predators follow. | 那里有食草动物，食肉动物跟着。 | |
| 100 | 09:51 | But this male lion has other things on his mind - he's searching for a mate. | 但这头雄狮还有其他事情要做——他在寻找伴侣。 | |
| 102 | 10:04 | Lions are the largest predators in the park. | 狮子是公园里最大的食肉动物。 | |

| 145 | 15:11 | When conditions are good,the colony stores more seed than it can eat, enabling the ants to sustain themselves when conditions turn bad. | 当环境好的时候，蚁群储存的种子比它能吃的还多，这样当环境变差的时候，蚂蚁就可以养活自己了。 | |
| 147 | 15:24 | Most antelope in the park congregate on the middle plateau because this habitat offers the best grazing. | 公园里的大多数羚羊聚集在中部高原，因为这个栖息地提供最好的放牧。 | |

| 171 | 17:53 | Ostriches live relatively long lives and can reach 40 years but predation is severe on young birds from a number of predators including caracal and lions. | 鸵鸟的寿命相对较长，可以达到40岁，但对幼鸟的捕食非常严重，包括甲壳动物和狮子。 | |
| 174 | 18:08 | Only one chick out of 8 to 10 clutches of eggs survives to adulthood. | 8到10窝卵中只有一只小鸡能活到成年。 | |
| 175 | 18:11 | Ostriches forage on small plants and grasses pulling the plants out and eating them,roots and all. | 鸵鸟以小植物和草为食，把植物拔出来，吃掉它们的根和所有的东西。 | |
| 177 | 18:22 | Like all dry-adapted animals,they obtain important moisture from the food they eat. | 像所有适应干旱的动物一样，它们从食物中获取重要的水分。 | |
| 178 | 18:26 | Neighboring Gemsbok share in the meager pickings. | 邻近的格姆博克人也分享了贫瘠的采摘。 | |
| 179 | 18:30 | Gemsbok are extreme desert specialists capable of surviving in the dunes of true deserts. | 宝石羚是极端的沙漠专家能够生存在真正的沙漠沙丘。 | |
| 181 | 18:37 | They occur across the park but prefer to congregate on the good feeding areas of the central plateau. | 它们分布在整个公园，但更喜欢聚集在中部高原的良好的喂养区。 | |
| 183 | 18:50 | They live in nomadic herds usually numbering 14 or more individuals although herds of more than a hundred are not uncommon. | 他们生活在游牧牧群中，通常有14个或更多的个体，尽管超过100个的牧群并不少见。 | |

| 187 | 19:10 | These herds contain both males and females. | 这些畜群既有雄性也有雌性。 | |
| 188 | 19:12 | This is unusual; most antelope live in segregated male or female herds. | 这是不寻常的；大多数羚羊生活在男女隔离的兽群中。 | |
| 190 | 19:20 | But here cohabiting is essential. | 但在这里同居是必不可少的。 | |
| 191 | 19:27 | In the arid park,forage is often unpredictable and Gemsbok can't afford for both food and mates to be hard to find, so they solve one of these problems by living together. | 在干旱的公园里，饲料常常是不可预测的，而Gemsbok无法负担食物和配偶的难求，所以他们通过共同生活来解决其中的一个问题。 | |

| 201 | 20:26 | Specially cushioned hooves act as shock absorbers,increasing grip. | 特别缓冲蹄作为减震器，增加抓地力。 | |
| 202 | 20:34 | Together their exposed rocky habitat and dexterity means Klipspringers rarely fall prey to terrestrial predators. | 加上它们裸露的岩石栖息地和灵巧的动作，它们很少成为陆地食肉动物的猎物。 | |
| 204 | 20:45 | But in the Karoo,death can just as easily come from the sky. | 但是在卡鲁，死亡也可以很容易地从天上降临。 | |
| 205 | 20:58 | The Karoo National Park contains one of the highest densities of Verreaux's eagles anywhere in South Africa. | 卡鲁国家公园里有南非所有地方最高密度的鹰。 | |
| 207 | 21:16 | These nest high on the forbidding dolerite cliff faces and hunt a range of small animals. | 它们在令人望而生畏的白云岩峭壁上筑巢，捕猎各种小动物。 | |

| 212 | 21:40 | But 9 out of 10 of their meals in the Karoo are Rock hyraxes also known as Dassies. | 但是他们在卡鲁的每10顿饭中就有9顿是岩鬣狗，也被称为达斯。 | |
| 214 | 21:50 | Dassies live almost exclusively on rocky habitats and cliffs. | 达西人几乎只生活在岩石栖息地和悬崖上。 | |
| 215 | 21:54 | They're well adapted to jumping between rocks. | 它们很适合在岩石之间跳跃。 | |
| 216 | 22:04 | Special glands keep their feet moist helping to increase friction. | 特殊的腺体使他们的脚保持湿润，有助于增加摩擦。 | |
| 217 | 22:12 | They are able to feed on the poorest resources if necessary. | 如果必要的话，他们能够以最贫穷的资源为生。 | |
| 218 | 22:20 | Stomachs full of microbes break down even the toughest Karoo vegetation. | 充满微生物的胃甚至会破坏最坚硬的卡鲁植被。 | |
| 219 | 22:30 | They are often seen sunning themselves on exposed rocky surfaces. | 它们经常在裸露的岩石表面晒太阳。 | |
| 220 | 22:35 | Although they are warm-blooded mammals, they have surprisingly variable body temperatures and are even capable of absorbing heat from the sun just like coldblooded animals such as lizards. | 尽管它们是温血哺乳动物，但它们的体温却出人意料地多变，甚至能够像蜥蜴等冷血动物一样吸收太阳热量。 | |
| 224 | 22:50 | Dassies feed in the close proximity of their rocky homes and never venture too far out of the safe zone so if attacked they can quickly scuttle for cover. | 达斯人在岩石家园附近觅食，从不冒险离开安全区太远，因此如果受到攻击，他们可以迅速逃窜寻找掩护。 | |

| 242 | 25:28 | The dolerite cliffs forming the upper levels of the Nuweveld Mountains are perfect for both eagles and Dassies. | 形成努韦维尔德山脉上层的辉绿岩悬崖是鹰和达斯的完美选择。 | |
| 244 | 25:45 | White streaks on the rocks stained by Dassie urine mark established dens. | 岩石上的白色条纹被达斯尿染色，形成了洞穴。 | |
| 245 | 25:56 | Dolerite formed as magma flowed to the surface millions of years ago. | 辉绿岩是数百万年前岩浆流到地表时形成的。 | |
| 246 | 26:00 | This molten rock spilled onto the surface and is the reason many of the Karoo mountains have characteristic flat tops. | 这些熔融的岩石溅到了地表，这也是许多卡鲁山脉具有典型平顶的原因。 | |
| 248 | 26:15 | Softer rock has been eroded away over eons leaving these imposing cliff faces standing above the desolate plains. | 更软的岩石被侵蚀了亿万年，留下这些壮观的悬崖面矗立在荒凉的平原之上。 | |

| 261 | 27:50 | Plains zebra have shadow stripes, and the pattern doesn't extend round the belly and down the legs. | 平原斑马身上有阴影条纹，图案不会从腹部延伸到腿部。 | |
| 263 | 27:58 | All zebras eat mainly grass and are always found in relatively open areas where sweet young shoots grow best. | 所有的斑马都以草为主食，而且总是生活在相对开阔的地方，那里甜嫩的嫩枝生长得最好。 | |
| 265 | 28:13 | No matter which habitat, finding food in the dry surroundings of the Karoo is a constant challenge. | 无论是哪种栖息地，在卡鲁干燥的环境中寻找食物都是一个不断的挑战。 | |
| 267 | 28:27 | Kudu avoid this by remaining in the thick riverine vegetation. | 库杜通过保留在茂密的河岸植被中来避免这种情况。 | |
| 268 | 28:31 | They're not fussy and eat a range of plants. | 他们不挑剔，吃各种植物。 | |
| 269 | 28:44 | Kudu are ruminants and after browsing for a few hours each morning they will spend the heat of the day chewing the cud. | 库杜是反刍动物，在每天早上浏览几个小时后，它们会在一天的炎热中咀嚼反刍动物。 | |
| 271 | 29:02 | To aid digestion food is chewed, Swallowed Regurgitated And chewed some more. | 为了帮助消化，食物要咀嚼，吞咽，反刍，再咀嚼一些。 | |
| 275 | 29:25 | This helps break down the complex cellulose in the plant material they eat. | 这有助于分解他们所吃的植物材料中复杂的纤维素。 | |
| 276 | 29:36 | The young Caracal starts a deadly game of cat and mouse. | 年轻的卡拉卡尔开始了一场致命的猫捉老鼠的游戏。 | |
| 277 | 29:43 | It might seem cruel but it's to make his prey safer to eat. | 这看起来很残忍，但这是为了让他的猎物吃起来更安全。 | |
| 278 | 29:52 | Cats play with their food to ensure that it's too weak to harm them, thereby preventing serious injury, as even a small bite can lead to infection. | 猫玩弄它们的食物，以确保它太弱，伤害他们，从而防止严重伤害，因为即使是一个小咬可能导致感染。 | |
| 281 | 30:05 | They only play with food that they can afford to. | 他们只玩他们能负担得起的食物。 | |
| 282 | 30:11 | If the risk of their prey escaping is too great they tend to go straight for the kill. | 如果猎物逃走的风险太大，它们倾向于直接捕杀。 | |
| 283 | 30:43 | Driven by an instinct to remove fur or feathers from his prey, he licks the mouse. | 在本能驱使下，他从猎物身上取下皮毛或羽毛，舔老鼠。 | |
| 285 | 30:50 | On larger kills he will remove the fur before eating it, but on a mouse it's not worth the effort. | 在更大的捕杀行动中，他会在吃掉皮毛之前把皮毛取下来，但在老鼠身上，这样做是不值得的。 | |
| 287 | 31:10 | When the time comes the cat kills its prey with one bite severing the spinal cord. | 当时机成熟时，猫会咬断脊髓，杀死猎物。 | |
| 289 | 31:24 | Caracal comes from the Turkish "karakulak" meaning black ear. | Caracal来自土耳其语“karakulak”，意思是黑耳朵。 | |
| 290 | 31:37 | He carefully spits out the intestines. | 他小心地把肠子吐出来。 | |

| 294 | 31:58 | But he's satisfied for now. | 但他现在很满意。 | |
| 295 | 32:09 | On the open plains,Gemsbok forage in the early morning light. | 在开阔的平原上，宝石羚在清晨的阳光下觅食。 | |
| 296 | 32:19 | This is to obtain not just food but also water. | 这不仅是为了获得食物，也是为了获得水。 | |
| 297 | 32:23 | Vegetation contains the most moisture in the morning. | 植物在早晨含有最多的水分。 | |
| 298 | 32:27 | And when water is in such short supply it's important to maximize the uptake in the food that's eaten. | 当水如此短缺时，最大限度地吸收所吃食物是很重要的。 | |
| 300 | 32:38 | Preventing water loss is important for all animals living here. | 防止水分流失对生活在这里的所有动物都很重要。 | |
| 301 | 32:45 | Gemsbok allow their body temperature to soar way above lethal limits for most mammals - anywhere between 96 and 113 degrees Fahrenheit. | Gemsbok允许它们的体温飙升到超过大多数哺乳动物的致死极限——在96到113华氏度之间。 | |
| 303 | 32:54 | This reduces the amount of water they would lose to transpiration by trying to keep their body temperature down. | 这就减少了它们通过降低体温而失去的水分。 | |
| 305 | 33:03 | But,higher temperatures affect the brain, so gemsbok have a network of tiny blood capillaries in their nasal cavities, which cools the blood before it reaches the head. | 但是，更高的温度会影响大脑，所以宝石羚的鼻腔中有一个微小的毛细血管网络，在血液到达头部之前冷却血液。 | |
| 308 | 33:23 | Smaller animals,such as Steenbok,suffer even more trying to regulate their body temperature. | 体型较小的动物，如Steenbok，在试图调节体温时会遭受更大的痛苦。 | |
| 310 | 33:32 | They stand less than one-and-a-half feet tall. | 他们身高不到一英尺半。 | |
| 311 | 33:38 | And being this small means they absorb relatively more heat than other larger animals. | 如此之小意味着它们比其他大型动物吸收更多的热量。 | |
| 312 | 33:45 | This is because their surface area is large compared to their volume. | 这是因为它们的表面积比体积大。 | |
| 313 | 33:49 | The smaller you are the bigger the problem. | 你越小问题就越大。 | |
| 314 | 34:00 | Like Steenbok,Klipspringer also suffer,but they have a special coat to help. | 像斯特恩博克一样，克利普斯普林格也遭受了痛苦，但他们有一件特殊的外套来帮助他们。 | |
| 315 | 34:03 | Their hair is hollow,trapping extra air, thereby maximizing its insulating abilities. | 它们的头发是中空的，可以吸收额外的空气，从而最大限度地发挥其绝缘能力。 | |

| 329 | 35:48 | This tolerance means eland don't waste precious water on evaporative cooling in dry conditions. | 这个公差意味着eland不会在干燥条件下浪费宝贵的水用于蒸发冷却。 | |
| 331 | 35:57 | Eland also feed largely at night and in the early morning to get the most water possible from their food. | 为了从食物中获取尽可能多的水分，大羚羊也主要在夜间和清晨进食。 | |
| 333 | 36:10 | Being big helps eland buffer the effects of variable conditions. | 变大有助于eland缓冲可变条件的影响。 | |
| 334 | 36:13 | But this comes at a cost - sustaining this great size means eland must forage widely and are always on the move. | 但这是有代价的——维持这么大的面积意味着大羚羊必须广泛觅食，而且总是在迁徙。 | |

| 186 | 15:55 | When erratic kalahari rains do fall, surface water collects on the compacted clay only to evaporate under the hot sun. | 当不稳定的卡拉哈里降雨确实下降，地表水收集在压实粘土只蒸发在炎热的阳光下。 | |
| 189 | 16:12 | Minerals and salts are left behind which over time become too concentrated for plants to grow. | 矿物质和盐类被留下，随着时间的推移，它们变得过于集中，植物无法生长。 | |
| 192 | 16:27 | For a pair of desert experts like these ostriches, there is no land too foreboding. | 对于一对像鸵鸟这样的沙漠专家来说，没有什么土地是不祥的。 | |
| 194 | 16:34 | The largest species of bird in the world, they stand at six and a half feet tall and weigh 220 pounds. | 它们是世界上最大的鸟类，身高6.5英尺，体重220磅。 | |
| 196 | 16:44 | They cannot fly, but make up for this by running at up to 43 miles per hour, 7 miles an hour faster than a lion. | 它们不会飞，但为了弥补这一点，它们以每小时43英里的速度奔跑，比狮子快7英里。 | |
| 200 | 16:55 | More remarkable than their speed is their ability to survive in the heat of the kgalagadi. | 比它们的速度更显著的是它们在卡拉加迪火山的高温下生存的能力。 | |
| 202 | 17:07 | They have exceptionally low water demands, getting almost all of the moisture they need from their mostly plant based diet. | 它们对水分的需求量极低，几乎可以从植物性饮食中获得所需的全部水分。 | |
| 205 | 17:17 | For the ostriches there is little time spent resting as they spend more than 60 percent of the day striding the landscape, looking for food. | 对于鸵鸟来说，它们几乎没有时间休息，因为它们一天中有60%以上的时间都在大踏步地寻找食物。 | |
| 209 | 17:40 | While nothing grows in the middle of the pan, animals still visit these open wastelands. | 虽然平底锅中间什么也没长出来，但动物们仍然会造访这些开阔的荒地。 | |
| 211 | 17:55 | They will congregate at these hollows and eat the soil in small quantities, taking on the minerals as a supplement to their diet, which is lacking at this tough time of the year. | 他们会聚集在这些洼地，少量食用土壤，摄入矿物质作为饮食的补充，而在一年中的这个艰难时期，这些矿物质是缺乏的。 | |
| 215 | 18:11 | The dry earth is not the only source of extra minerals available in the kgalagadi. | 干土并不是卡拉加迪地区额外矿物质的唯一来源。 | |
| 217 | 18:24 | This female gemsbok is heavily pregnant. | 这只雌性大羚羊怀孕了。 | |
| 218 | 18:31 | In the dry winter her diet is lacking much needed nutrients, which will become ever more important when nursing her newborn. | 在干燥的冬天，她的饮食缺乏所需的营养，这将变得越来越重要，当她的新生儿护理。 | |
| 221 | 18:40 | To make up for this lack she turns to an unlikely source - the rib of a large herbivore. | 为了弥补这个不足，她转向一个不太可能的来源-一个大型食草动物的肋骨。 | |
| 223 | 18:54 | Perhaps a wildebeest or perhaps even another gemsbok. | 也许是一只角马，或者甚至是另一只羚羊。 | |
| 224 | 18:57 | She'll chew the bones of other animals to extract minerals such as calcium and phosphorus. | 她会咀嚼其他动物的骨头来提取钙和磷等矿物质。 | |
| 226 | 19:05 | It's an example of nature's innovation which allows animals like her to survive in incredibly difficult habitats. | 这是大自然创新的一个例子，它让像她这样的动物能够在极其困难的栖息地生存。 | |
| 229 | 19:16 | She belongs to possibly the most well-adapted and iconic of all the desert dwelling species. | 她可能是所有沙漠居住物种中适应能力最强、最具标志性的一个。 | |
| 231 | 19:23 | At about 4 feet tall at the shoulder, gemsbok weigh around 530 pounds. | gemsbok的肩膀大约有4英尺高，重约530磅。 | |
| 233 | 19:41 | These majestic antelope are known for their horns, which average more than three feet long from ribbed base to razor sharp tip. | 这些雄伟的羚羊以它们的角而闻名，从肋状的底部到锋利的尖端平均有三英尺多长。 | |
| 236 | 19:54 | An injury at a young age can cause a deformity in growth. | 幼年受伤会导致发育畸形。 | |
| 237 | 20:01 | This could put the pregnant cow at a disadvantage when it comes to defense against predators. | 这可能使怀孕的母牛在防御捕食者时处于不利地位。 | |
| 239 | 20:10 | Thus far she's been unhindered by the deformity - able to live life as a productive member of the herd. | 到目前为止，她还没有受到残疾的阻碍——能够作为一个多产的牧群成员生活。 | |
| 241 | 20:19 | But things are different for the bulls. | 但公牛的情况不同。 | |
| 242 | 20:33 | Gemsbok are one of the few antelope in which the horns of males are shorter than those of females. | 羚羊是为数不多的雄性角比雌性角短的羚羊之一。 | |
| 244 | 20:41 | But they're also thicker and stronger, better preparing their bearers for battles for dominance and the right to mate. | 但它们也更厚更强壮，更好地为它们的熊准备战斗的优势和交配的权利。 | |
| 247 | 21:10 | When two bulls come to a stalemate, only a third can come between them. | 当两头公牛陷入僵局时，只有三分之一的公牛能挡在他们之间。 | |
| 249 | 21:28 | The skin around bulls' necks is up to a quarter inch thick to protect them during these skirmishes. | 公牛脖子上的皮厚达四分之一英寸，以在这些小冲突中保护它们。 | |
| 251 | 21:40 | The gemsbok survive thanks to a range of adaptations to life in a parched land. | 由于对干旱土地上生活的一系列适应，宝石羚得以生存。 | |
| 253 | 21:54 | They are able to go much of their lives without drinking; Getting the moisture they need from their food instead. | 他们能够在生活的大部分时间里不喝酒，而是从食物中获取所需的水分。 | |
| 255 | 22:06 | To make this possible, the gemsboks' bodies are geared toward saving water. | 为了使这成为可能，宝石羚的身体是为了节约用水。 | |
| 257 | 22:19 | While many mammals will pant or sweat to cool down, both processes waste water. | 虽然许多哺乳动物会喘息或出汗来降温，但这两种方法都会处理废水。 | |
| 259 | 22:28 | Instead, the gemsbok can allow their normal body temperature of 96.2 degrees fahrenheit to rise to a staggering 113 degrees. | 相反，gemsbok可以让他们96.2华氏度的正常体温上升到惊人的113度。 | |
| 262 | 22:41 | They can handle a hot body but an overheated brain can be life threatening. | 他们可以处理热的身体，但过热的大脑可能会危及生命。 | |
| 264 | 22:51 | To counter this, in the gemsbok's moist cool nasal passages there's an extensive network of blood capillaries. | 为了解决这个问题，在gemsbok潮湿凉爽的鼻腔里有一个广泛的毛细血管网。 | |
| 267 | 23:02 | This cools the blood, keeping the animal's head at a safe temperature while the body temperature soars. | 这样可以冷却血液，使动物的头部在体温上升时保持在安全的温度。 | |
| 270 | 23:13 | The gemsbok will then lose the excess heat in the cooler night, which is also when they do most of their grazing. | 宝石羚将失去多余的热量在凉爽的夜晚，这也是他们做他们的大部分放牧。 | |
| 272 | 23:23 | At night even dead grass can absorb 40 percent of its weight in airborne moisture. | 在晚上，即使是枯草也能吸收空气中40%的水分。 | |
| 274 | 23:28 | It's enough to satisfy the gemsboks' low water requirements. | 这足以满足宝石羚的低需水量。 | |
| 276 | 23:37 | And it allows them to spend more time in the dunes than their smaller antelope counterparts. | 这使得它们在沙丘上的时间比它们的小羚羊长。 | |
| 278 | 23:51 | In the southwest portions of the park lie dune fields extending for a full 500 miles. | 在公园的西南部，沙丘绵延了整整500英里。 | |
| 280 | 23:59 | Their sand is turned ochre red from iron oxide enveloping the grains. | 它们的沙子被包裹在颗粒上的氧化铁变成赭红色。 | |
| 282 | 24:08 | Here, tough grasses take hold along the ridges. | 在这里，坚韧的草沿着山脊生长。 | |
| 283 | 24:15 | And in some areas, grow in thick, dense swathes. | 在一些地区，生长在厚厚的密集地带。 | |
| 284 | 24:24 | It's an apparent banquet for animals like the gemsbok. | 这显然是一个像宝石羚这样的动物的宴会。 | |
| 285 | 24:30 | But there's more to this grass than meets the eye. | 但这片草地上的东西远不止这些。 | |
| 286 | 24:35 | Known as kalahari sour grass, its young shoots soon toughen and secrete an acidic substance which is unpalatable to the animals and causes them skin irritations. | 它的嫩枝被称为卡拉哈里酸草，很快就会变硬并分泌出一种酸性物质，这种物质对动物来说是不好吃的，会引起皮肤过敏。 | |
| 290 | 24:55 | An inedible sea of seeming abundance as cruel as any desert mirage. | 像沙漠海市蜃楼一样残酷的一片无法食用的富饶海洋。 | |
| 292 | 25:04 | But not all of the kgalagadi's plants are as deceptive. | 但并不是所有的卡拉加迪植物都具有欺骗性。 | |
| 293 | 25:09 | In the nutrient-rich riverbeds, the camelthorns are a lot more than just scaffolding for nests. | 在营养丰富的河床上，骆驼刺不仅仅是筑巢的脚手架。 | |
| 295 | 25:16 | In the driest time they produce large seed pods. | 在最干燥的时候，它们会产生大的豆荚。 | |
| 297 | 25:24 | Their silvery coat reflects the sun's hot rays just like the springboks' rumps, thus minimizing evaporation. | 它们银色的皮毛反射着太阳的灼热光线，就像跳羚的臀部一样，从而减少了蒸发。 | |
| 300 | 25:37 | Low in tannins and high in protein, these pods are an important source of nutrition for many of the kgalagadi's animals. | 这些豆荚单宁含量低，蛋白质含量高，是许多克加拉加德动物的重要营养来源。 | |
| 303 | 25:50 | And this herd of wildebeest cashes in on the feast. | 这群牛羚在宴会上大赚一笔。 | |
| 304 | 26:00 | In order to germinate, the hard-shelled seeds must pass through their digestive systems where enzymes break down their outer shells. | 为了发芽，硬壳种子必须通过消化系统，在消化系统中酶会分解外壳。 | |
| 307 | 26:11 | They will soon be spread by the wildebeest in repayment of the tree's nutritious favor. | 它们很快就会被牛羚传播，以回报树的营养。 | |
| 309 | 26:23 | In the cooler part of the day, the herd takes to the riverbed to lie in the sun. | 在天气凉爽的时候，牛群会到河床上晒太阳。 | |
| 311 | 26:35 | With many eyes on the lookout, they can take time to relax. | 有许多眼睛在观察，他们可以花时间放松。 | |
| 312 | 26:39 | But a herd in the nossob riverbed is about to have an altogether more dramatic day. | 但是，诺索布河床上的一只牛群即将迎来一个更加戏剧性的一天。 | |
| 314 | 26:53 | The cheetah family have been on the move all morning seeking a meal fit for five and they've spotted the wildebeest. | 猎豹一家整个上午都在四处奔走，寻找适合五个人吃的食物，他们发现了这只角马。 | |
| 317 | 27:03 | The day's hunt is about to begin. | 一天的狩猎即将开始。 | |
| 318 | 27:12 | The cats keep a low profile, getting as close as possible. | 猫保持低调，尽量靠近。 | |
| 319 | 27:22 | Suddenly the chase is on. | 突然，追逐开始了。 | |
| 320 | 27:38 | A calf injures itself in the chaos of the herd. | 小牛在混乱的牛群中受伤。 | |
| 321 | 27:54 | The cheetahs surround it but are cautious of the bucking prey. | 猎豹围着它，但对猛扑的猎物很谨慎。 | |
| 322 | 27:56 | Outnumbered five to one, this will surely be the end for the young wildebeest. | 以五比一的优势，这将是年轻角马的终结。 | |
| 324 | 28:11 | But the cheetahs are inexperienced. | 但是猎豹没有经验。 | |
| 325 | 28:19 | And the calf isn't going to go down without a fight. | 小牛也不会不打一架就倒下的。 | |
| 326 | 28:32 | They're at a loss of how to make the kill. | 他们不知道怎么杀人。 | |
| 327 | 28:42 | Tired from the exertion of the chase, the cheetah retreat to the shade to recover their strength. | 猎豹追得筋疲力尽，只好退到树荫下恢复体力。 | |
| 329 | 28:53 | And the wildebeest has a chance to get away. | 牛羚有机会逃脱。 | |
| 330 | 29:04 | But they're not about to let it go that easily. | 但他们不会轻易放过的。 | |
| 331 | 29:14 | And it's every wildebeest for itself. | 每只角马都是为了自己。 | |
| 332 | 29:25 | The injured calf is abandoned to its fate. | 受伤的小牛被遗弃了。 | |
| 333 | 29:47 | Barely able to carry its own weight, the calf manages to keep eyes on the closest threat. | 由于几乎无法承受自身重量，小牛设法盯着最近的威胁。 | |
| 335 | 29:58 | It matches its harassers, move for move in a terrifying dance. | 它与骚扰者相匹配，以一种可怕的舞蹈一步一步地移动。 | |
| 336 | 30:08 | Eventually, exhaustion begins to take hold. | 最终，疲惫开始占据主导地位。 | |
| 337 | 30:13 | In both predators and prey. | 无论是捕食者还是猎物。 | |
| 338 | 30:32 | After a drawn-out saga, the day comes to the strangest of ends. | 在一段旷日持久的传奇故事之后，这一天终于有了最奇怪的结局。 | |
| 340 | 30:42 | The cheetahs abandon the opportunity. | 猎豹放弃了这个机会。 | |
| 341 | 30:50 | Despite the huge investment of energy, they will see no reward. | 尽管投入了巨大的能源，他们还是看不到任何回报。 | |
| 342 | 31:02 | The calf's refusal to surrender has bought it extra time. | 小牛拒绝投降为它赢得了额外的时间。 | |
| 344 | 31:08 | A fine example of the fact that there are few foregone conclusions in this unpredictable land. | 这是一个很好的例子，说明在这片变幻莫测的土地上几乎没有定论。 | |
| 347 | 31:20 | But as night falls, a different set of threats may present itself. | 但随着夜幕降临，一系列不同的威胁可能会出现。 | |
| 349 | 31:26 | And with lions around, the calf will be lucky to make it to morning. | 有狮子在身边，小牛犊能活到早上就很幸运了。 | |
| 351 | 31:46 | As day breaks the kgalagadi's springbok are making the most of the early hours. | 天亮时，卡拉加迪的跳羚车充分利用了凌晨的时间。 | |
| 353 | 31:55 | While they rely largely on fresh grass after periods of rain, springbok have adapted to make the most of scant resources during the barren winter. | 虽然雨后它们主要依靠新鲜的草，但春羚已经适应了在贫瘠的冬季充分利用稀少的资源。 | |
| 356 | 32:13 | And in some cases these occur in an unlikely location; Beneath the bone dry sands of the auob riverbed. | 在某些情况下，它们发生在一个不太可能的地方：在奥布河床的干砂下面。 | |
| 358 | 32:20 | The antelope uncover hidden roots before plucking them with dexterous lips. | 羚羊在用灵巧的嘴唇拔出隐藏的根之前先把它们揭开。 | |
| 360 | 32:26 | By adapting their diets, springbok can sustain themselves well enough to continue with life as usual, despite the apparent lack in their environment. | 通过调整饮食习惯，跳羚可以很好地维持自己的生活，尽管他们的环境明显缺乏营养。 | |
| 364 | 32:38 | And even in these tough times the males are preoccupied by the desire for dominance and mating opportunities. | 即使在这样艰难的时期，雄性也被支配欲和交配机会所占据。 | |
| 367 | 32:51 | This male moves between the surrounding females, checking each in turn for reproductive readiness. | 这只雄性在周围雌性之间移动，依次检查每只雌性的生殖准备情况。 | |
| 369 | 32:57 | But they're unresponsive. | 但他们没有反应。 | |
| 370 | 33:01 | The brief rut and mating season happened months ago after the wet season when the herd was in prime condition. | 短暂的发情期和交配期发生在几个月前的雨季之后，当时牛群处于最佳状态。 | |
| 373 | 33:11 | Now the females share none of the male's interest. | 现在雌鸟对雄鸟毫无兴趣。 | |
| 374 | 33:16 | Young males will still size each other up. | 年轻的雄性仍然会互相体谅。 | |
| 375 | 33:23 | But their contests hold none of the intensity that will occur when the herd is at full fitness. | 但是，他们的比赛没有达到牧群完全健康时的强度。 | |
| 377 | 33:42 | While the springbok have had an early start to the day, another group of kgalagadi icons are later to rise. | 虽然跳羚队在这一天有一个很早的开始，另一组克加拉加迪的图标是后来上升。 | |
| 379 | 33:52 | A family of meerkats. | 猫鼬科。 | |
| 380 | 34:01 | The pack takes great caution before leaving the safety of the burrow - scanning their surroundings for threats. | 在离开洞穴的安全地带之前，狼群会非常小心地扫描周围的环境，寻找威胁。 | |
| 383 | 34:12 | And for good reason; They have pups with them. | 有充分的理由，他们带着小狗。 | |
| 385 | 34:21 | Like the sociable weavers, meerkats work together to insulate themselves from the extremes of the environment. | 像善于交际的织布者一样，猫鼬也在一起工作，使自己远离极端的环境。 | |
| 387 | 34:33 | But instead of building up they dig down, making their homes beneath the ground. | 但是，他们不建房子，而是把房子埋在地下。 | |
| 389 | 34:42 | And they're not the only ones living here. | 他们不是唯一住在这里的人。 | |
| 390 | 34:52 | Their roommates, the yellow mongooses, have had a sleep in. | 他们的室友，黄色的猫鼬，已经睡了一觉。 | |
| 391 | 34:58 | But they have less patience when it comes to finding breakfast. | 但是他们在找早餐的时候没有耐心。 | |
| 392 | 35:00 | And are first to go hunting for insects. | 他们是第一个去寻找昆虫的人。 | |
| 393 | 35:15 | Following their lead the meerkats venture out, slowly at first. | 猫鼬一开始慢慢地跟着它们出去了。 | |
| 395 | 35:33 | They soon come across their other neighbors the ground squirrels. | 他们很快就遇到了他们的邻居地松鼠。 | |
| 397 | 35:41 | They too live as a family, with mom keeping a careful eye out. | 他们也像一家人一样生活着，妈妈很小心地看着他们。 | |
| 398 | 35:46 | Unlike the others, the squirrels are satisfied with a mainly vegetable based diet - nibbling away contentedly. | 与其他松鼠不同的是，松鼠满足于以蔬菜为主的饮食——心满意足地啃食。 | |
| 401 | 36:01 | These three social species happily share their turf with each other but will all jealously defend it against rivals from their own species. | 这三个群居物种很高兴地分享自己的地盘，但都会嫉妒地保卫自己的地盘，以对抗自己物种的竞争对手。 | |
| 405 | 36:13 | As the day goes on, each makes the most of what their surroundings have to offer. | 随着时间的推移，每个人都充分利用了周围环境所提供的一切。 | |
| 407 | 36:21 | While the mongooses and squirrels will split up to forage as individuals, the meerkats stick together, watching each others' backs to the last. | 当猫鼬和松鼠分开作为个体觅食时，猫鼬会粘在一起，看着彼此的背影直到最后。 | |
| 411 | 36:35 | While the meerkats' day is just beginning, one of the kgalagadi's other subterranean dwellers is getting ready to head back underground. | 正当猫鼬节刚刚开始的时候，克加拉加迪的另一个地下居民正准备返回地下。 | |
| 414 | 36:48 | This cape fox spent the cold winter night hunting alone, digging for its favorite prey of mice. | 这只海角狐狸在寒冷的冬夜独自打猎，挖掘它最喜欢的老鼠猎物。 | |
| 416 | 36:55 | It enjoys the morning warmth before heading to sleep in its den, where it will raise its pups come early summer. | 它享受着早晨的温暖，然后在巢穴里睡觉，在初夏的时候，它会在那里饲养幼崽。 | |
| 419 | 37:04 | Weighing in at 11 pounds, the cape fox is the smallest canid in southern africa. | 重达11磅的角狐是南非最小的犬科动物。 | |
| 421 | 37:14 | It's also the only true fox living here and is endemic to the region. | 它也是唯一一只生活在这里的真正的狐狸，是该地区特有的。 | |
| 423 | 37:26 | The little predator is vulnerable to bigger carnivores and it must return to safety below ground. | 小食肉动物很容易受到较大食肉动物的攻击，它必须回到地下安全地带。 | |
| 425 | 37:36 | The entrance to its den is carefully concealed beneath the branches of one of the kgalagadi's hardy shrubs. | 它的巢穴入口被小心地隐藏在克加拉加迪一种耐寒灌木的树枝下面。 | |
| 428 | 37:48 | These plants are almost as well adapted as the animals which eat them. | 这些植物的适应能力几乎和吃它们的动物一样好。 | |
| 430 | 37:58 | Like the 'three-thorn', so named for the way it grows, always branching off in increments of three. | 就像“三根刺”，因其生长方式而得名，总是以三根为增量分叉。 | |
| 433 | 38:10 | And the 'black-hook', named for its dark thorns. | 还有“黑钩”，因其黑色的刺而得名。 | |
| 434 | 38:17 | To survive here these plants have tiny, thin leaves to minimize water loss through evaporation - and thorns to avoid being devoured in large quantities. | 为了在这里生存，这些植物有微小的、薄的叶子，以尽量减少蒸发造成的水分损失，还有刺，以避免被大量吞噬。 | |
| 437 | 38:36 | Like the smaller shrubs, thorns are crucial to the survival of camelthorns. | 像较小的灌木一样，刺对骆驼刺的生存至关重要。 | |
| 439 | 38:45 | This young tree will eventually grow to resemble the comparative giant behind it. | 这棵小树最终会长成与它后面的巨人相似的样子。 | |
| 441 | 38:55 | And when it does, it will serve another important purpose for the kgalagadi's birds, giving them branches on which to perch. | 当它做到这一点时，它将为卡拉加迪的鸟类提供另一个重要的用途，给它们提供栖息的树枝。 | |
| 444 | 39:14 | Red headed finches are the same size as the sociable weavers. | 红头雀和群居的织布者一样大。 | |
| 445 | 39:19 | These grain eaters will gather in flocks numbering in the hundreds. | 这些吃五谷的必成群聚集，数目甚多。 | |
| 447 | 39:27 | Unlike many in the kgalagadi they must drink frequently, congregating around the park's rare water sources. | 与克加拉加迪的许多人不同，他们必须经常喝酒，聚集在公园稀有的水源周围。 | |
| 449 | 39:37 | But the finches are vulnerable to predation by birds of prey, and they dare not relax on open ground - diving in for two sips before returning to the cover of the camelthorn's branches. | 但是，这些雀鸟很容易被猛禽捕食，它们不敢在开阔地上放松——在回到骆驼刺树枝的覆盖处之前，它们会潜入水中啜饮两口。 | |
| 453 | 39:57 | But as much as the camelthorn serves them with a protected perch, it provides the same service to the birds of prey that hunt them. | 但是骆驼刺为它们提供了一个受保护的栖木，它也为捕食它们的猛禽提供了同样的服务。 | |
| 457 | 40:11 | The kgalagadi is a hotbed of raptor activity. | 卡拉加迪是猛禽活动的温床。 | |
| 458 | 40:18 | This southern pale chanting goshawk will prey on small birds like weavers and finches. | 这种南方苍鹰会以织布工和雀等小鸟为食。 | |
| 460 | 40:24 | But its favorite food is small mammals. | 但它最喜欢的食物是小型哺乳动物。 | |
| 461 | 40:33 | It devours its latest victim in the branches of a camelthorn. | 它在骆驼刺的树枝上吞食最新的猎物。 | |
| 462 | 40:43 | The kgalagadi riverbeds provide ideal habitat for the goshawk. | kgalagadi河床为苍鹰提供了理想的栖息地。 | |
| 463 | 40:50 | Open ground leaves rodents visible and the branches of camelthorns provide high perches from which to launch diving attacks. | 开阔的地面上可以看到啮齿动物，骆驼刺的枝桠提供了很高的栖木，可以从那里发动潜水攻击。 | |
| 466 | 41:00 | And when mice are few and far between, at around 80 sociable weavers in less than a mile of riverbed, there's no shortage of food for the goshawk. | 当老鼠很少时，在不到一英里的河床里，大约有80只群居的织布工，苍鹰就不缺食物了。 | |
| 469 | 41:18 | Having eaten its fill it uses the tree for one last purpose - cleaning its sharp beak by rubbing it against the rough bark. | 吃了它的填充物后，它用这棵树做最后一个用途——用粗糙的树皮摩擦它锋利的喙来清洁它。 | |
| 472 | 41:30 | The goshawk isn't the only hunter that relies on camelthorns. | 苍鹰不是唯一依赖骆驼刺的猎人。 | |
| 474 | 41:43 | While their branches are a launching pad for the raptor, they also provide a favorite resting place of another of the kgalagadi's cats. | 虽然它们的树枝是猛禽的发射台，但它们也提供了另一只克加拉加迪猫最喜欢的休息地。 | |
| 477 | 41:59 | But this little predator may seem out of place in its wild environment. | 但是这种小食肉动物在它的野生环境中似乎不合适。 | |
| 479 | 42:07 | The african wild cat looks surprisingly domestic. | 这只非洲野猫看起来出奇地像只家猫。 | |
| 480 | 42:11 | Mainly active at night, it spends much of its day relaxing in these branches. | 它主要在夜间活动，白天大部分时间都在这些树枝上放松。 | |
| 482 | 42:18 | Its stripy legs are perfectly camouflaged against the tree's gnarled bark. | 它有条纹的腿在粗糙的树皮上被完美地伪装起来。 | |

| 132 | 14:02 | Broad swathes of the park's patchwork have soils too shallow and acidic for forests to thrive. | 公园里大片错落有致的土地太浅，酸性太强，森林无法茁壮成长。 | |
| 134 | 14:11 | Fynbos,translated as 'fine bush', is a unique collection of shrubland and heathland plants that grows prolifically in these areas. | Fynbos，翻译为“优良的灌木”，是一个独特的收集灌木和荒地植物，生长在这些地区丰富。 | |
| 137 | 14:25 | It adds astounding diversity to the park. | 它为公园增添了惊人的多样性。 | |
| 138 | 14:35 | 70 percent of the 7700 fynbos plant species are endemic to South Africa. | 7700种fynbos植物中有70%是南非特有的。 | |
| 140 | 14:47 | Flowers of all shapes and forms decorate the hardy brush. | 各种形状和形状的花朵装饰着耐寒的画笔。 | |
| 141 | 14:56 | But the flowers are more than just adornments. | 但是花不仅仅是装饰品。 | |
| 142 | 15:05 | Their bright colors attract a range of insects and birds essential to their life cycle. | 它们鲜艳的颜色吸引了一系列昆虫和鸟类，这些昆虫和鸟类对它们的生命周期至关重要。 | |
| 144 | 15:16 | The flower of this protea plant has a regular visitor. | 这种变形植物的花有常客。 | |
| 145 | 15:21 | Green protea beetles occur wherever their favorite food source does. | 绿色变形甲虫出现在它们最喜欢的食物来源所在的地方。 | |
| 147 | 15:31 | It buries itself headfirst in the welcoming flower, gorging on the sweet nectar. | 它头朝下埋入迎宾的花丛中，狼吞虎咽地喝着香甜的花蜜。 | |
| 149 | 15:41 | As it does so it performs the crucial role of pollinating the flower so the next generation of proteas can grow. | 当它这样做的时候，它扮演着为花授粉的关键角色，这样下一代的蛋白质就可以生长了。 | |
| 152 | 16:05 | For some fynbos pollination is carried out by the wind, which spreads pollen as it blows through the dense brush. | 对一些fynbos来说，授粉是由风进行的，风吹过浓密的灌木丛时传播花粉。 | |
| 154 | 16:17 | The wind also helps to spread another crucial element in the fynbos life cycle. | 风也有助于传播fynbos生命周期中的另一个关键因素。 | |
| 156 | 16:25 | For many of these plants, rebirth first requires the intervention of one of nature's most destructive forces. | 对许多这样的植物来说，重生首先需要大自然最具破坏性的力量之一的介入。 | |
| 159 | 16:35 | Fire. | 开火。 | |
| 160 | 16:39 | Fires are naturally caused by lightning or sparks made by falling rocks, but today people are usually responsible. | 火灾自然是由闪电或落石产生的火花引起的，但今天人们通常对此负责。 | |
| 163 | 16:53 | As the blaze decimates the living scrub, fueled by the wind, its flames trigger a reaction from the hard cones of many plants. | 当大火在风的推动下毁灭了活着的灌木丛时，它的火焰引发了许多植物坚硬的球果的反应。 | |
| 167 | 17:04 | The heat causes them to release their seeds into the fertile ash, allowing the next generation to propagate. | 热量使它们将种子释放到肥沃的灰烬中，让下一代得以繁殖。 | |
| 170 | 17:18 | In this way,fire is essential to fynbos. | 这样，火对FYNBO来说是必不可少的。 | |
| 171 | 17:22 | And it's this positive relationship with a destructive force that wins the fynbos plenty of room to grow. | 正是这种与破坏性力量的积极关系为FYNBO赢得了足够的发展空间。 | |
| 174 | 17:34 | For the forests,fire damage is devastating. | 对森林来说，火灾造成的破坏是毁灭性的。 | |

| 196 | 19:48 | Instead of accessing more light by growing tall, they've evolved to make the most of what's available to them. | 它们并没有通过长高来获得更多的光，而是进化来充分利用现有的光。 | |
| 198 | 19:58 | A gene known as neochrome enables the ferns to detect a wider range of the light spectrum than other plants. | 一种被称为新色素的基因使蕨类植物比其他植物能探测到更宽的光谱范围。 | |
| 200 | 20:08 | This allows them to grow even below the shady fortress of trees above them. | 这使得它们甚至可以生长在树荫掩映的堡垒之下。 | |
| 202 | 20:17 | It's such a successful adaptation that ferns have been around for 360 million years. | 这是如此成功的适应，蕨类植物已经存在了3.6亿年。 | |
| 204 | 20:29 | The rivers moving through the forest provide homes for many small animals. | 穿过森林的河流为许多小动物提供了家园。 | |
