00:00:17,760 --> 00:00:29,760
《地球脉动2》  第一季  第二集

2
00:00:38,660 --> 00:00:41,830
世界上超过八千米的山峰
There are only fourteen peaks in the world

3
00:00:41,870 --> 00:00:44,630
屈指可数
that rise to over 8000 metres.

4
00:00:52,420 --> 00:00:57,420
它们全部位于喜马拉雅地区
All of them are here, in the Himalayas.

5
00:01:06,670 --> 00:01:11,230
在极端低温与暴风雪的洗礼下
Lethally cold, scoured by gales and blizzards,

6
00:01:11,600 --> 00:01:16,330
这些山脉成为地球上生存条件最苛刻的地区
these mountains are among the most hostile places on Earth.

7
00:01:26,070 --> 00:01:30,350
然而  仍有动物能够生活在这里
Yet, a few special animals manage to live here.

8
00:01:37,980 --> 00:01:39,610
雪豹
Snow leopards.

9
00:01:41,940 --> 00:01:44,520
与所有高山生物相同
Like all creatures of the high mountains,

10
00:01:44,520 --> 00:01:48,320
为了生存  他们必须从体型和行为上
they have had to adapt both their body and their behaviour

11
00:01:48,320 --> 00:01:50,120
充分适应环境
in order to survive.

12
00:01:58,220 --> 00:02:00,640
极高海拔之上的生存
Life at extreme altitude

13
00:02:00,740 --> 00:02:05,040
塑造出了这个星球上最顽强的动物
has shaped some of the toughest animals on the planet.

14
00:02:09,510 --> 00:02:16,010
山脉

15
00:02:28,220 --> 00:02:31,860
阿拉伯半岛上的山地被阳光炙烤得发烫
The sunbaked mountains of the Arabian Peninsula.

16
00:02:33,580 --> 00:02:36,410
英语解说  大卫·爱登堡

17
00:02:36,420 --> 00:02:40,100
它们的海拔也许只是喜马拉雅山脉的零头
They may only be a fraction of the height of the Himalayas,

18
00:02:41,210 --> 00:02:44,430
但却异常险峻
but they are still so dizzyingly steep

19
00:02:44,510 --> 00:02:48,840
很多地方几乎无法立足
that in many places it's almost impossible to get a foothold.

20
00:02:57,720 --> 00:03:02,570
而努比亚羱羊还是栖息于此
Yet Nubian ibex have made this their home.

21
00:03:14,330 --> 00:03:18,620
羱羊选择在最陡峭的绝壁上养育幼仔
The ibex choose the steepest cliffs to raise their young,

22
00:03:19,130 --> 00:03:22,220
环境安全  没有天敌
in safety, beyond the reach of predators.

23
00:03:33,200 --> 00:03:37,750
在生活在这里也要付出代价
But living in this sanctuary comes with a cost.

24
00:03:41,320 --> 00:03:44,550
山崖过于陡峭
These nursery slopes are so steep,

25
00:03:44,560 --> 00:03:48,010
几乎没有任何积水
there is almost no standing water up here.

26
00:03:56,460 --> 00:04:01,590
为了饮水  羱羊必须下到
So to drink, an ibex family must descend into the valley...

27
00:04:03,580 --> 00:04:05,490
三百米下的峡谷之中
...1,000 feet below.

28
00:04:08,310 --> 00:04:11,160
母羊选出一条最安全的下山路径
The mothers pick out the safest way down.

29
00:04:13,580 --> 00:04:17,900
四只柔软的分趾蹄胜过最好用的登山鞋
With soft cloven hooves that grip better than any climbing shoe,

30
00:04:17,960 --> 00:04:20,850
让他们成为最高超的登山者
they are the most accomplished mountaineers.

31
00:04:33,120 --> 00:04:37,190
但新生的雏羊还在蹒跚学步
But the newborn kids are still having to find their feet.

32
00:04:44,500 --> 00:04:46,960
这是他们第一次下山
This is their first descent.

33
00:04:49,100 --> 00:04:52,010
一次失蹄就可能一命呜呼
One mistake could make it their last.

34
00:05:11,910 --> 00:05:15,880
跟着成年羱羊  小羊们终于到达山谷
Following the adults, the kids finally reach the valley.

35
00:05:19,900 --> 00:05:23,880
但回到平地上  他们就很容易遭到攻击
But once on level ground, they're vulnerable.

36
00:05:32,500 --> 00:05:35,730
赤狐埋伏许久了
Red foxes lie in wait.

37
00:05:50,260 --> 00:05:51,770
一有危险迹象
At the first sign of danger,

38
00:05:51,770 --> 00:05:55,610
羱羊幼仔便本能地奔回陡坡
the young ibex instinctively run back to steeper ground.

39
00:06:10,010 --> 00:06:14,190
但爬上这块突出的岩石可能是个错误
But heading for this particular rocky outcrop could be a mistake.

40
00:06:15,860 --> 00:06:17,910
这有九米高
It's a 30-foot drop.

41
00:06:20,710 --> 00:06:22,520
赤狐把它们困住了
The fox has them trapped...

42
00:06:22,780 --> 00:06:24,540
或者看起来是这样
or so it seems.

43
00:06:43,870 --> 00:06:47,180
这正是羱羊与生俱来的本领
This is what ibex were born to do.

44
00:07:03,690 --> 00:07:07,660
四散而逃的羊群让赤狐难以选择目标
Scattering makes it hard for the fox to pick a target.

45
00:07:22,920 --> 00:07:25,700
显然它也无法追上峭壁
And it certainly can't follow them up here.

46
00:07:26,810 --> 00:07:30,560
只能等待某只羱羊失蹄跌落
All it can do is wait for one to slip and fall.

47
00:07:52,680 --> 00:07:55,190
但这些小羊学得很快
But these youngsters are fast learners,

48
00:07:55,190 --> 00:07:59,150
现在几乎可以和双亲一样如履平地了
and they're now almost as sure-footed as their parents.

49
00:08:35,060 --> 00:08:38,080
赤狐只能去别处觅食
The fox will have to find its meal elsewhere.

50
00:08:44,980 --> 00:08:47,630
今天还真不是个好日子
It's just not been a good day.

51
00:08:56,220 --> 00:09:00,180
小羱羊终于喝上水了
Now, at last, the young ibex can drink.

52
00:09:03,370 --> 00:09:04,450
但很快他们又得
But they'll soon need to

53
00:09:04,450 --> 00:09:07,390
回到峭壁上的安全区域
return to the safety of the sheer cliffs.

54
00:09:13,400 --> 00:09:17,420
在峭壁上行走固然很难
Mastering precipitous terrain is always challenging,

55
00:09:17,820 --> 00:09:19,940
但对于高山动物而言
but there are more fundamental problems

56
00:09:19,940 --> 00:09:21,710
还有更根本的难题
for life in the mountains.

57
00:09:40,680 --> 00:09:44,020
阿尔卑斯山脉  欧洲最高的山峰
The Alps. Europe's highest peaks.

58
00:09:45,240 --> 00:09:49,170
时至冬季  食物极度匮乏
It's winter, and food is desperately short.

59
00:10:00,700 --> 00:10:04,690
金雕不得不花费整个白天
A golden eagle has to spend every daylight hour

60
00:10:04,970 --> 00:10:10,020
俯视山坡  寻找食物
scanning the slopes for something, somewhere, to eat.

61
00:10:19,790 --> 00:10:23,700
长达两米的翼展让她
Her seven-foot wingspan allows her to glide effortlessly

62
00:10:23,710 --> 00:10:26,970
一天可以轻松滑翔一百六十公里
for 100 miles in a single day.

63
00:10:36,360 --> 00:10:38,110
非凡的视力
Her extraordinary eyes

64
00:10:38,120 --> 00:10:41,810
让她可以看到三公里外的猎物
enable her to spot prey from two miles away.

65
00:10:51,140 --> 00:10:54,510
但她并非这里唯一的觅食者
But she is not the only one who's looking for food.

66
00:10:56,560 --> 00:11:00,150
一旦发现良机  必须快速行动
When she spots a chance, she must move fast.

67
00:11:04,950 --> 00:11:07,700
她能以三百二十公里的时速俯冲而下
She can dive at 200 miles an hour.

68
00:11:07,970 --> 00:11:10,260
只有游隼能飞得更快
Only a peregrine is faster.

69
00:11:45,540 --> 00:11:50,220
在冬季  即使鹰类也几乎完全仰赖腐尸度日
During winter, even eagles rely almost entirely on carrion.

70
00:11:51,300 --> 00:11:53,100
这是一只死去的狐狸
It's a dead fox,

71
00:11:53,110 --> 00:11:55,690
这顿美餐能让她支撑数日
and it could sustain her for days.

72
00:11:59,190 --> 00:12:01,420
其它食腐者只能等着了
Other scavengers must defer.

73
00:12:04,740 --> 00:12:07,670
饥饿的乌鸦很快重新鼓起勇气
The hungry crows soon regain their courage.

74
00:12:10,130 --> 00:12:13,060
他们想尽办法  试图分一杯羹
They'll try any trick to steal a morsel.

75
00:12:21,320 --> 00:12:24,270
顽固地令人厌烦
And they are annoyingly persistent.

76
00:12:46,730 --> 00:12:50,290
但这群乌鸦是她最不需要担心的
But this mob are the least of her worries.

77
00:12:58,240 --> 00:13:00,890
一只更大的金雕抢走了食物
A bigger eagle takes control.

78
00:13:06,050 --> 00:13:09,220
但这顿美餐太过重要  不能轻易放弃
But this kill is too important to give up.

79
00:13:11,580 --> 00:13:13,330
必须奋起一搏
So she must fight.

80
00:13:28,940 --> 00:13:32,060
她暂时抢回了尸体
For the moment, she's won the carcass back.

81
00:13:33,320 --> 00:13:37,550
但这样的猎物会引来方圆数公里内所有的鹰
But a kill like this will attract every eagle for miles around.

82
00:14:06,400 --> 00:14:10,370
最终依然是最强者赢得大部分食物
As ever, the strongest wins the lion's share.

83
00:14:13,460 --> 00:14:16,150
抢不到那具尸体
Unable to defend the carcass any longer,

84
00:14:16,150 --> 00:14:19,600
第一只雕只能继续它的觅食之旅
the first eagle must now continue its search.

85
00:14:21,110 --> 00:14:24,280
也许下一次饱餐就是数日之后的事情了
It may be many days before she feeds again.

86
00:14:29,420 --> 00:14:31,300
只有最具竞争力的生物
Only the most competitive

87
00:14:31,310 --> 00:14:34,290
才能在山脉的寒冬中存活下来
will survive the perils of the mountain winter.

88
00:15:04,430 --> 00:15:06,030
一场雪崩
An avalanche.

89
00:15:06,030 --> 00:15:08,690
十万吨积雪
100,000 tonnes of snow

90
00:15:08,820 --> 00:15:10,820
以一百三十公里的时速席卷而下
travelling at 80 miles an hour,

91
00:15:10,970 --> 00:15:14,420
足以粉碎沿途的一切
capable of smashing everything in its path.

92
00:15:54,430 --> 00:15:56,430
北美洲的山脉
The mountains of North America

93
00:15:56,430 --> 00:16:00,080
每年要发生数千起雪崩
are hit by thousands of avalanches every year.

94
00:16:13,970 --> 00:16:18,290
然而有一种动物整个冬季
Yet one animal spends the whole winter slumbering

95
00:16:18,290 --> 00:16:22,460
都在这些极易发生雪崩的山坡上冬眠
within the snow on these avalanche-prone slopes.

96
00:16:32,740 --> 00:16:36,470
待春天来临  它们就出洞了
And when spring comes, they emerge.

97
00:16:49,880 --> 00:16:51,870
在这些山脉中
All across these mountains,

98
00:16:51,870 --> 00:16:54,560
灰熊将巢筑在背风坡厚厚的积雪之下
grizzly bears make their winter dens

99
00:16:54,560 --> 00:16:59,250
海拔高达三千米
10,000 feet up in the deep snow of leeward slopes.

100
00:17:01,670 --> 00:17:04,730
他们在隆冬半梦半醒之际
And while they were half-asleep in the depths of winter,

101
00:17:04,730 --> 00:17:06,360
产下幼崽
their young were born.

102
00:17:10,970 --> 00:17:13,620
现在这些熊宝宝正迈出他们
Now these cubs are taking their first steps

103
00:17:13,630 --> 00:17:15,560
走向外界的第一步
into the outside world.

104
00:17:40,240 --> 00:17:43,200
熊妈妈带着三只幼崽
This mother is leading her three youngsters

105
00:17:43,200 --> 00:17:46,100
去找东西吃
to a place where they can find food.

106
00:17:51,710 --> 00:17:55,470
他们得尽快下山
They need to descend as quickly as possible.

107
00:17:57,790 --> 00:18:00,620
雪崩肆虐后的残骸清楚地表明
The debris from an avalanche is clear evidence

108
00:18:00,620 --> 00:18:04,370
这片山坡仍然非常不稳定
that this slope is still dangerously unstable.

109
00:18:16,720 --> 00:18:19,780
此地不宜久留
This is not a place to dawdle.

110
00:18:25,850 --> 00:18:28,480
他们继续前行还有另一个原因
And they have another reason to keep moving.

111
00:18:30,060 --> 00:18:31,930
在巢里呆了五个月后
After five months in the den,

112
00:18:31,930 --> 00:18:34,840
这些灰熊饿得正慌
these bears are very hungry.

113
00:18:40,250 --> 00:18:43,280
这片山峰之间冬眠的灰熊
Bears that have hibernated throughout these peaks

114
00:18:43,280 --> 00:18:48,340
现在都下山了  那里的春天来得更早
now all descend to the valleys, where spring comes earliest.

115
00:18:56,460 --> 00:19:01,170
落基山脉的季节变换迅速而突然
In the Rockies, seasonal change is swift and dramatic.

116
00:19:11,780 --> 00:19:13,160
几天时间内
In just a few days,

117
00:19:13,160 --> 00:19:17,850
白雪皑皑的山脉便会绿意盎然
the slopes turn from white to green.

118
00:19:39,890 --> 00:19:44,560
几周前还深埋在冰天雪地里的牧场
Meadows that only a few weeks ago were buried beneath the snow

119
00:19:44,570 --> 00:19:46,950
现在生机勃勃
are now full of life.

120
00:20:05,790 --> 00:20:10,520
但山峦之间  好时光不会太久
But in these mountains, the good times will not last long.

121
00:20:11,950 --> 00:20:14,880
所以灰熊必须尽快进食
So the bears must feed as fast as they can.

122
00:20:18,990 --> 00:20:20,520
夏季的几个月里
During the summer months,

123
00:20:20,520 --> 00:20:25,250
一只成年灰熊靠吃植物能长一百八十公斤
an adult can put on 180 kilos gorging on plants

124
00:20:25,580 --> 00:20:27,860
要是能再...
and, if they can catch them...

125
00:20:29,520 --> 00:20:31,080
逮几只土拨鼠就更好了
a marmot or two.

126
00:20:35,120 --> 00:20:39,570
但现在灰熊们还有其他事情要做
But just now, the bears have something else on their minds.

127
00:20:43,420 --> 00:20:44,980
天气转暖
It's becoming warmer,

128
00:20:44,980 --> 00:20:48,360
灰熊急切地想脱下它们厚重的冬衣
and the bears are keen to shed their thick winter coats.

129
00:20:51,840 --> 00:20:55,550
母熊给小熊们做了示范
Mothers show the cubs what to do about this.

130
00:21:05,940 --> 00:21:07,350
他们很快就学会了
They'll soon catch on.

131
00:21:10,720 --> 00:21:15,130
有一些树似乎特别适合搓背
Some trees, it seems, are particularly suitable for rubbing.

132
00:21:15,940 --> 00:21:18,050
熊们都有自己的偏好
Bears have their favourites

133
00:21:18,140 --> 00:21:20,990
他们会长途跋涉  去找喜欢的树
and will travel long distances to visit them.

134
00:21:24,080 --> 00:21:27,330
身上有些痒  急需挠一挠
Some itches just have to be scratched.

135
00:21:49,160 --> 00:21:53,420
这个山谷中大约有三十只熊
There are now around 30 bears in this one valley.

136
00:21:59,890 --> 00:22:05,670
每只熊摩擦时都会留下易于辨认的独特气味
As they rub, each leaves an individual and recognisable scent.

137
00:22:09,120 --> 00:22:12,980
所以树上很快会留有附近灰熊的气味
So the tree soon carries a list of who's around,

138
00:22:13,750 --> 00:22:16,690
或许可以避免个体之间的争斗
which might help individuals to avoid a fight.

139
00:22:18,410 --> 00:22:20,760
为了更好地散布自己的气味
To best spread their scent,

140
00:22:21,180 --> 00:22:23,710
他们得用后背好好地蹭一蹭
they really have to put their back into it.

141
00:23:07,310 --> 00:23:09,210
但是夏天很短暂
But summer is short.

142
00:23:09,770 --> 00:23:12,810
痒痒挠满意之后
Itches satisfactorily scratched,

143
00:23:13,510 --> 00:23:15,290
是时候该进食了
it's time to eat.

144
00:23:18,500 --> 00:23:19,790
几个月后
In a couple of months,

145
00:23:19,790 --> 00:23:22,650
他们就要回自己的窝里冬眠
they will have to return to their dens to hibernate,

146
00:23:23,260 --> 00:23:26,360
所以现在必须尽可能地增重
so now they must put on as much weight as they can.

147
00:23:33,870 --> 00:23:38,740
山里的冬天来得迅猛
Winter in the mountains returns fast and hits hard.

148
00:23:53,490 --> 00:23:58,340
落基山脉地区的温度会降至零下五十四度
Temperatures in the Rockies will drop to -54 degrees,

149
00:23:58,940 --> 00:24:01,430
以至于空气中的水分
so cold that moisture in the air

150
00:24:01,440 --> 00:24:06,430
会直接凝结成冰晶  俗称钻石尘
freezes into tiny crystals called diamond dust.

151
00:24:30,380 --> 00:24:35,030
山猫是少数冬天还在活动的捕猎者
This bobcat is one of the few hunters to remain active in winter.

152
00:24:39,010 --> 00:24:42,590
他领地内的大多数猎物都
Most of his prey is now hidden beneath the snow

153
00:24:42,690 --> 00:24:44,870
隐藏在茫茫大雪之下
that covers his entire territory.

154
00:24:51,010 --> 00:24:55,350
他通过辨认极其微弱的声音来捕捉猎物
He hunts by listening for the faintest sound of movement.

155
00:24:56,020 --> 00:25:00,080
为了避免踩雪的脚步声暴露行踪
And to prevent crunching footsteps from revealing his presence,

156
00:25:00,210 --> 00:25:03,820
他用岩石当落脚点
he uses boulders as stepping stones.

157
00:25:23,960 --> 00:25:25,130
逮住一只老鼠
A mouse.

158
00:25:26,660 --> 00:25:28,640
但这远远不够
But one is not enough.

159
00:25:45,340 --> 00:25:49,460
积雪越深越难发现猎物
The deeper the snow, the harder it is to detect prey,

160
00:25:49,910 --> 00:25:52,750
努力捕食却往往空手而归
and the rewards for the effort can be disappointing.

161
00:25:56,320 --> 00:25:57,860
这么说毫不夸张
To say the least.

162
00:26:03,520 --> 00:26:05,980
深冬时节积雪实在太深
By midwinter, the snow is so deep

163
00:26:05,980 --> 00:26:09,050
山猫被迫离开他们的领地
that bobcats are forced to leave their territories

164
00:26:09,060 --> 00:26:11,570
寻找更易于捕捉的猎物
to try and find easier hunting.

165
00:26:36,640 --> 00:26:39,750
但这只山猫运气不错
And this bobcat may be in luck.

166
00:26:41,020 --> 00:26:44,210
因为这个山谷得自然之眷顾
For this particular valley is blessed.

167
00:26:49,610 --> 00:26:52,160
这条河永不结冰
A river here never freezes.

168
00:26:54,990 --> 00:26:58,190
火山温泉带来的热量
It's fed by a volcanic hot spring

169
00:26:58,310 --> 00:27:00,160
使河水升温
that heats these waters

170
00:27:00,160 --> 00:27:03,550
比周围空气的温度高了五十余度
to 50 degrees warmer than the surrounding air.

171
00:27:09,190 --> 00:27:13,130
各种饥肠辘辘的动物来此觅食
Hungry animals of all kinds come here to feed.

172
00:27:37,980 --> 00:27:39,140
到了冬天
Throughout the winter,

173
00:27:39,140 --> 00:27:41,400
对于那些老道的捕猎者而言
the river is full of food

174
00:27:41,460 --> 00:27:43,780
河里满是食物
for those who know how to catch it.

175
00:27:55,920 --> 00:27:59,310
在这里连土狼都学会了捕鱼
Here, even the coyotes have become fishermen.

176
00:28:03,400 --> 00:28:05,580
但是捕鱼对山猫来说很难
But hunting is hard for a cat

177
00:28:05,580 --> 00:28:08,080
因为他们讨厌下水
that's not used to getting its feet wet.

178
00:28:17,470 --> 00:28:20,290
所以他必须谨慎选择目标
So he must choose his target with care.

179
00:28:33,120 --> 00:28:34,960
白颊鸭来了
Goldeneye ducks.

180
00:28:36,100 --> 00:28:38,450
但他能够靠近到扑得着吗
But can he get close enough to pounce?

181
00:29:11,700 --> 00:29:14,970
也许对岸的机会更大点
Perhaps he'll have more luck on the other side.

182
00:29:32,000 --> 00:29:36,600
河里的热气温暖了周围的树林
Here, steam from the river warms the surrounding trees,

183
00:29:37,410 --> 00:29:40,900
所以林子里可能有猎物
so up in the branches, there could be prey.

184
00:29:46,450 --> 00:29:48,890
前提是他能爬得上去
If only he could get to it.

185
00:29:50,570 --> 00:29:52,190
这有六米高
It's 20 feet up.

186
00:30:09,840 --> 00:30:11,920
最终收获一只松鼠
At last... a squirrel.

187
00:30:14,100 --> 00:30:17,380
不是很多  但是足以支撑他继续捕食
Not much, but enough to keep him going.

188
00:30:20,490 --> 00:30:24,830
想要渡过山里的冬天需要坚韧不拔的意志
To survive a winter in these mountains takes tenacity,

189
00:30:25,810 --> 00:30:29,120
而山猫是其中的佼佼者
and bobcats have that in abundance.

190
00:30:46,660 --> 00:30:49,540
这是一座赤道雪山
Snow on the equator.

191
00:30:51,050 --> 00:30:53,690
与落基山脉不同  这里的山脉
Unlike the Rockies, in these mountains

192
00:30:53,690 --> 00:30:56,060
没有明显的四季
there are no marked seasons.

193
00:31:08,810 --> 00:31:11,100
这是非洲的肯尼亚山
This is Africa's Mount Kenya.

194
00:31:12,240 --> 00:31:15,120
海拔超过五千米
It's 17,000 feet high,

195
00:31:15,530 --> 00:31:18,600
峰顶温度比周围的热带草原
which makes its summit some 30 degrees colder

196
00:31:18,710 --> 00:31:20,480
低三十度左右
than the surrounding savanna.

197
00:31:25,270 --> 00:31:29,100
巨型石南  半边莲和千里光
Giant heathers, lobelias and groundsel

198
00:31:29,200 --> 00:31:31,140
生长在山顶斜坡上
grow on its upper slopes.

199
00:31:31,680 --> 00:31:34,110
它们在炎炎烈日下茁壮成长
They all thrive in the tropical sun.

200
00:31:35,420 --> 00:31:38,470
毕竟赤道每天都是夏天
After all, every day is summer.

201
00:31:40,800 --> 00:31:42,930
但一旦太阳下山
But once the sun sets,

202
00:31:43,070 --> 00:31:47,560
每个夜晚都像冬天般寒冷
every night becomes as bitterly cold as winter.

203
00:31:55,910 --> 00:31:59,680
气温降到零下五度
The temperature drops to five degrees below freezing,

204
00:32:00,440 --> 00:32:04,330
山坡变成了冰雪花园
turning the mountainside into a garden of ice.

205
00:32:25,390 --> 00:32:27,190
一切都冻结了
Everything freezes,

206
00:32:28,430 --> 00:32:32,870
但是木本千里光有办法保护自己
but the cabbage groundsels have a way of protecting themselves.

207
00:32:39,010 --> 00:32:43,990
它们合起革质叶片形成一道保温层
They close up their leathery leaves to form an insulating blanket

208
00:32:44,000 --> 00:32:46,900
以保护中心脆弱的蓓蕾
that shields their vulnerable central bud.

209
00:32:59,170 --> 00:33:01,110
寒夜将尽
Night comes to an end...

210
00:33:05,010 --> 00:33:07,070
阳光回归大地
...and the sunshine returns.

211
00:33:12,100 --> 00:33:14,990
木本千里光舒展它们的叶子
The groundsels spread their leaves wide

212
00:33:15,080 --> 00:33:17,560
再一次沐浴在阳光之中
to bask in the sunshine once again.

213
00:33:36,910 --> 00:33:39,950
安第斯山脉的黎明来到
Dawn in the High Andes.

214
00:33:48,960 --> 00:33:52,890
在这里  升起的朝阳同样解放了
Here too, the rising sun brings rapid relief

215
00:33:52,890 --> 00:33:56,290
生活在火山山峰之间的动物
to animals living amongst these volcanic peaks.

216
00:34:00,140 --> 00:34:02,800
山兔鼠早早起来
Mountain viscacha are up early

217
00:34:02,810 --> 00:34:07,700
抢占最佳位置  享受第一缕阳光
to claim the best places to catch the sun's first rays.

218
00:34:29,330 --> 00:34:34,210
对于其他的动物  太阳更加受到欢迎
For others up here, the sunrise is even more welcome.

219
00:34:37,140 --> 00:34:39,470
这里的海拔超过四千米
At over 14,000 feet,

220
00:34:39,510 --> 00:34:43,050
是世界上海拔最高的火烈鸟栖息地
this is the highest flamingo colony in the world.

221
00:34:45,410 --> 00:34:47,760
这里的夜晚非常寒冷
At night, it gets so cold

222
00:34:47,760 --> 00:34:50,500
连盐水湖都会结冰
that even this salty water freezes over.

223
00:34:52,990 --> 00:34:55,710
这些火烈鸟就被冻在了冰里
And now the flamingos are trapped in the ice.

224
00:35:01,660 --> 00:35:04,830
终于太阳晒薄了冰面
Eventually, the sun thins the ice,

225
00:35:05,750 --> 00:35:09,560
但是火烈鸟仍然需要努力冲破冰层
but it's still a struggle for the flamingos to break free.

226
00:35:30,870 --> 00:35:33,910
走在薄冰上总是危机四伏
Walking on thin ice is always risky.

227
00:35:45,550 --> 00:35:48,320
而且当你踩着高跷的时候
And it's hard to retain one's dignity...

228
00:35:49,730 --> 00:35:52,540
哪还顾得上体面和优雅
...especially when you're wearing stilts.

229
00:36:05,920 --> 00:36:07,630
海拔如此之高
At these altitudes,

230
00:36:07,910 --> 00:36:13,670
太阳的热力很快从救星变成了威胁
the sun's power can quickly turn from salvation to threat.

231
00:36:19,960 --> 00:36:22,030
由于大气稀薄
The atmosphere is so thin,

232
00:36:22,300 --> 00:36:26,030
无法阻挡紫外线的辐射
there is very little protection from ultraviolet radiation.

233
00:36:27,650 --> 00:36:31,910
上午十点钟在开阔地带逗留就已经十分危险
By mid-morning, it's risky to linger out in the open.

234
00:36:35,190 --> 00:36:38,460
鼠兔被迫寻找阴凉处避暑
The viscacha are forced to head for the shade.

235
00:36:43,490 --> 00:36:47,090
而湖面上则无处可藏
Out on the lake, there is nowhere to hide.

236
00:36:53,450 --> 00:36:55,570
盐湖的白色盐层反射着
The white crust of the soda lake

237
00:36:55,570 --> 00:36:57,550
太阳的光芒
reflects the sun's glare

238
00:36:57,910 --> 00:37:01,580
增强了紫外线的杀伤力
and increases the impact of its ultraviolet rays.

239
00:37:06,700 --> 00:37:07,520
正午时分
By midday,

240
00:37:07,520 --> 00:37:11,270
裸露的人类肌肤四分钟内就会被晒伤
uncovered human skin will burn in four minutes.

241
00:37:17,350 --> 00:37:20,470
但这似乎无法妨碍到火烈鸟
But this doesn't seem to bother the flamingos.

242
00:37:21,270 --> 00:37:24,030
事实上  它们正在列队游行
In fact, they are on parade.

243
00:37:55,080 --> 00:37:56,750
在繁殖季节
During the breeding season,

244
00:37:56,750 --> 00:38:00,500
即便在一天中最热的时刻
the flamingos perform these peculiar courtship dances

245
00:38:00,510 --> 00:38:02,970
火烈鸟也在不停表演着奇异的求爱舞蹈
even through the hottest time of the day.

246
00:38:10,160 --> 00:38:13,850
他们求爱心切  甚至没时间停下来进食
They are so eager, they don't even pause to feed.

247
00:38:33,050 --> 00:38:35,450
尽管求爱规则让人摸不着头脑
The rules are something of a mystery

248
00:38:35,960 --> 00:38:37,620
但在跳了一个月之后
but, after a month of dancing,

249
00:38:37,620 --> 00:38:40,040
所有的鸟儿都配对成功
all the birds will have paired off

250
00:38:40,550 --> 00:38:42,720
并准备开始交配
and will be getting ready to mate.

251
00:38:48,990 --> 00:38:53,260
高山之上  很少有其他动物来打扰火烈鸟
Up here, there are few other creatures to bother the flamingos,

252
00:38:53,610 --> 00:38:55,420
从另一方面讲  也少有其他动物
but then, few other creatures

253
00:38:55,420 --> 00:38:58,480
能够忍受这样的生活条件
could even tolerate these conditions.

254
00:39:01,630 --> 00:39:04,720
对于耐力极佳的动物而言
So for animals that have the endurance,

255
00:39:05,120 --> 00:39:08,300
深山堪称生存的圣殿
mountains can be sanctuaries.

256
00:39:20,750 --> 00:39:24,090
那些在我们看来
But rocky peaks which to us, perhaps,

257
00:39:24,090 --> 00:39:26,370
似乎象征着永恒的岩石山峰
seem a symbol of permanence,

258
00:39:26,770 --> 00:39:29,200
其实要脆弱得多
are more fragile than they appear.

259
00:39:33,650 --> 00:39:35,500
如今在阿尔卑斯山
Today in the Alps,

260
00:39:35,700 --> 00:39:40,540
人类的侵犯甚至影响到顶峰的环境状况
human encroachment is changing even the highest summits.

261
00:39:54,270 --> 00:39:55,400
在落基山脉
In the Rockies,

262
00:39:55,400 --> 00:39:59,100
升高的气温缩短了冬眠的时间
rising temperatures are shortening winter hibernation

263
00:39:59,100 --> 00:40:02,560
也阻碍了食料植物的生长
and stifling the growth of valuable food plants.

264
00:40:08,650 --> 00:40:11,550
在安第斯山脉  一些冰川
And in the Andes, some glaciers

265
00:40:11,550 --> 00:40:16,380
在短短三十年内面积减少了百分之五十
have shrunk by 50% in just 30 years.

266
00:40:26,150 --> 00:40:28,990
如今  甚至连喜马拉雅山脉都变得十分脆弱
Even the Himalayas are now vulnerable.

267
00:40:33,010 --> 00:40:35,360
这里汇集着大多数世上最高的山峰
With most of the world's tallest peaks

268
00:40:35,370 --> 00:40:38,360
占地面积八十六万平方公里
and covering a third of a million square miles,

269
00:40:38,390 --> 00:40:41,740
是世界上最大的山脉
this is the greatest mountain range of all.

270
00:40:48,610 --> 00:40:50,980
而这里气温升高的速度
And here, temperatures are now rising

271
00:40:50,980 --> 00:40:53,420
快于全球平均水平
faster than the global average.

272
00:40:54,640 --> 00:40:59,070
雪线向山峰处退去
As the snow line retreats further and further up these peaks,

273
00:40:59,540 --> 00:41:02,710
野生动植物的生存空间日益减少
there is less and less space for wildlife,

274
00:41:03,230 --> 00:41:05,090
恶化的条件威胁着
and that is a challenge

275
00:41:05,090 --> 00:41:09,680
一种美丽山地动物的生存
for one of the most majestic of all mountain creatures.

276
00:41:28,650 --> 00:41:30,350
雪豹
The snow leopard.

277
00:41:34,380 --> 00:41:39,640
由于行踪隐蔽  雪豹的生活细节一直是个谜
Seldom seen, the detail of their lives has long been a mystery,

278
00:41:40,370 --> 00:41:45,420
但现在  借助最先进的远程摄像技术
but now, at last, helped by the latest remote-camera technology,

279
00:41:45,710 --> 00:41:49,430
我们终于能够近距离观察他们
we are getting closer to them than ever before.

280
00:41:54,300 --> 00:41:55,600
雪豹数量稀少
They are very rare,

281
00:41:55,600 --> 00:41:59,120
百平方公里内只有四只
only about four of them in 40 square miles.

282
00:42:00,690 --> 00:42:04,330
只是因为猎物数量不足以维系更多的生命
There is simply not enough prey to sustain more.

283
00:42:09,930 --> 00:42:12,720
雪豹是独居动物
They live solitary lives.

284
00:42:12,720 --> 00:42:15,420
尽管如此  他们仍能很好地掌握
Nonetheless, they are well aware of the presence

285
00:42:15,430 --> 00:42:17,560
邻居们的存在和动向
and the movements of their neighbours,

286
00:42:17,830 --> 00:42:21,990
因为他们会在几个特殊地点给对方留下信息
because they leave messages in a few special places.

287
00:42:24,920 --> 00:42:28,420
像这样用脸颊摩擦特定的岩石
They rub particular rocks with their cheeks

288
00:42:31,610 --> 00:42:34,410
再喷射上自己的尿液
and then spray them with urine.

289
00:42:37,060 --> 00:42:41,090
两种味道创造出了独一无二的签名
The two perfumes create a unique signature.

290
00:42:45,950 --> 00:42:47,770
尽管没有直接看到彼此
Any other leopard can know

291
00:42:47,850 --> 00:42:50,750
雪豹也能判断出
which of its neighbours passed this way,

292
00:42:50,960 --> 00:42:53,680
是哪位邻居曾经到此一游
without ever making direct contact.

293
00:42:56,720 --> 00:43:00,710
有些时候雪豹们必须聚到一起
But there are times when snow leopards must come together,

294
00:43:01,060 --> 00:43:04,090
而场面通常都很暴力
and the event is often violent.

295
00:43:16,850 --> 00:43:20,140
一只成年雌雪豹和她的女儿
An adult female and her daughter.

296
00:43:30,130 --> 00:43:34,700
雌雪豹花费了两年时间哺育幼崽
She has devoted the last two years to raising her cub

297
00:43:34,700 --> 00:43:37,510
很快  幼崽就要断奶了
and very soon, it will be weaned.

298
00:43:40,280 --> 00:43:44,780
目前  幼崽依旧完全依靠自己的母亲
For now, the cub is still entirely dependent on its mother.

299
00:43:50,500 --> 00:43:55,020
但这样长时间的共处会引发问题
But staying together as long as this could cause problems.

300
00:43:59,160 --> 00:44:01,290
雌雪豹此时又到了发情期
The female is now in heat again,

301
00:44:01,290 --> 00:44:04,970
雄雪豹只需闻到她的信号便会知晓
and any male that smells her signature will know that.

302
00:44:15,920 --> 00:44:20,080
从此刻起  雌雪豹幼崽的生命陷入了危机
From this moment on, her cub's life is at risk.

303
00:44:22,750 --> 00:44:25,940
雄雪豹会杀死非亲生的幼崽
Males kill cubs that are not their own.

304
00:44:31,270 --> 00:44:36,180
但雌雪豹此时正被体内无法控制的欲望驱使着
But the mother is now driven by an urge that she cannot control.

305
00:44:39,680 --> 00:44:43,050
她让雄雪豹知道了她的确切位置
She lets the males know exactly where she is.

306
00:44:56,920 --> 00:45:00,900
从这片高地  她的声音可以传遍方圆数公里
From up here, she can be heard for miles around.

307
00:45:20,450 --> 00:45:22,880
一只年轻雄雪豹在荒野中出现
A young male emerges from the wilderness,

308
00:45:23,140 --> 00:45:24,380
迫切地想要找到雌雪豹
eager to find her.

309
00:45:28,450 --> 00:45:31,220
雪豹们很少碰面
Snow leopards meet so infrequently

310
00:45:31,510 --> 00:45:34,560
以致整个场面充斥着不确定和紧张的气氛
that there is uncertainty and tension.

311
00:45:43,150 --> 00:45:45,160
然而更糟的还在后面
And it's about to get worse.

312
00:45:53,910 --> 00:45:57,030
另一只体型更为健壮的雄雪豹也来了
Another, bigger male has arrived.

313
00:46:06,240 --> 00:46:10,200
雌雪豹和幼崽被困在两个竞争对手之间
The mother and cub are trapped between the rivals.

314
00:46:15,380 --> 00:46:17,060
幼崽命在旦夕
The cub is now in danger.

315
00:46:17,060 --> 00:46:19,210
母亲必须尽快行动
Mother must act fast.

316
00:46:20,540 --> 00:46:23,300
为了转移雄雪豹对幼崽的注意力
To divert the males' attention from her cub,

317
00:46:23,300 --> 00:46:25,750
她顺从地滚动着身体
she rolls over submissively.

318
00:46:39,250 --> 00:46:41,310
雄雪豹的注意力都集中在了雌雪豹身上
With the males fixed on the female,

319
00:46:41,320 --> 00:46:43,820
幼崽得以借此机会脱身
the cub has a chance to escape.

320
00:46:50,620 --> 00:46:53,710
两只雄雪豹从两侧接近雌雪豹
The males close in on the mother from both sides,

321
00:46:53,790 --> 00:46:56,030
渴望将其占为己有
keen to claim her for their own.

322
00:47:00,770 --> 00:47:02,990
决斗在所难免
A fight is inevitable.

323
00:47:24,800 --> 00:47:28,440
雌雪豹试图逃跑并保护她的幼崽
The female moves to escape and protect her cub.

324
00:47:29,200 --> 00:47:31,080
但健硕的雄雪豹紧跟着她
But the big male follows her.

325
00:47:43,240 --> 00:47:47,770
在没有交配前  雄雪豹是不会放她走的
He will not let her leave until he has mated with her.

326
00:48:05,130 --> 00:48:10,930
雄雪豹走后  雌雪豹终于与幼崽重聚
With the males gone, the female is at last reunited with her cub.

327
00:48:14,120 --> 00:48:16,650
但她不幸受了伤
But she has been injured.

328
00:48:26,870 --> 00:48:30,990
多亏了她的妈妈  幼崽才能活下来
The cub, however, is alive, thanks to its mother.

329
00:48:41,050 --> 00:48:45,480
在雌雪豹伤口痊愈之前  她已无法捕猎
Until her injury heals, she won't be able to hunt.

330
00:48:48,190 --> 00:48:51,980
山地动物就这样挣扎在存活的边缘
Mountain animals survive on the very edge of existence.

331
00:48:55,470 --> 00:48:59,070
雌雪豹和幼崽从此消失不见
Mother and cub were not seen again.

332
00:49:07,520 --> 00:49:11,510
直到一个月后  在高高的山脊上
Until over a month later, high on a ridge,

333
00:49:11,530 --> 00:49:13,750
远程摄像机捕捉到了
a remote camera was triggered.

334
00:49:17,960 --> 00:49:19,700
雌雪豹的身影
The female cat.

335
00:49:19,840 --> 00:49:23,860
她已不再跛足而行  却形单影只
She's no longer limping, but she's now alone.

336
00:49:29,340 --> 00:49:32,860
雌雪豹离开后一个小时
Then, an hour after the female has left,

337
00:49:32,860 --> 00:49:35,200
摄像机再次启动
the camera is triggered again.

338
00:49:41,550 --> 00:49:43,140
是幼崽
It's her cub,

339
00:49:43,590 --> 00:49:48,510
开始了迈向成年和独立的第一步
taking her first steps towards adulthood and independence.

340
00:49:50,150 --> 00:49:53,640
幼崽大概很少有机会与母亲重逢了
She is unlikely to see her mother again.

341
00:49:53,690 --> 00:49:54,780
但不时地
But every now and then,

342
00:49:55,490 --> 00:49:59,330
他们会通过在岩石上留下的信息
they will be reunited through the messages they leave

343
00:49:59,550 --> 00:50:01,180
间接地团聚
on the marking rocks.

344
00:50:04,690 --> 00:50:08,060
幼崽虽被母亲成功养大
Her mother has succeeded in raising her,

345
00:50:08,400 --> 00:50:11,460
但前方的生存之路仍充满荆棘
but life ahead will be challenging,

346
00:50:11,710 --> 00:50:15,170
而她几乎全部要独自面对
and she will spend nearly all of it alone.

347
00:50:17,890 --> 00:50:20,800
只有最顽强的动物
Only the toughest can survive

348
00:50:20,800 --> 00:50:22,620
才能在世界最高屋脊上
among the savage beauty

349
00:50:22,630 --> 00:50:25,890
这片美丽的蛮夷之地存活
of the world's highest mountains.

350
00:50:33,410 --> 00:50:34,620
下一集
Next time...

351
00:50:34,990 --> 00:50:37,200
我们到世界各地探索丛林
we explore the world's jungles.

352
00:50:39,400 --> 00:50:43,900
地球上充满惊喜和创造力无与伦比的地方
Places of surprise and invention unrivalled on Earth...

353
00:50:45,470 --> 00:50:49,360
那里的生存之战最为激烈
...where the battle for survival is at its most intense.
