00:00:17,760 --> 00:00:29,760
《地球脉动2》  第一季  第三集

2
00:00:36,150 --> 00:00:41,300
地球是人类已知的唯一存在生命的星球
Earth is the only planet we know of where life exists.

3
00:00:43,990 --> 00:00:47,250
而且这里生机盎然
And, here, it does so in abundance.

4
00:00:52,150 --> 00:00:54,850
丛林宛如伊甸园般美好
The jungle is Eden.

5
00:00:57,520 --> 00:01:01,270
它仅占地球表面积的百分之六
It covers less than 6% of the Earth's surface

6
00:01:01,340 --> 00:01:03,690
却分布着世界上
but it's home to half of all

7
00:01:03,690 --> 00:01:06,120
一半的动植物物种
the plants and animals on land.

8
00:01:10,310 --> 00:01:14,950
丛林拥有适宜的光照  水源和养分
Jungles have just the right amount of light, water and nutrients,

9
00:01:15,050 --> 00:01:19,030
千百年来一直如此
and they have had every day for millennia.

10
00:01:23,640 --> 00:01:26,770
在这里生存应该不难
Life here should be easy.

11
00:01:35,620 --> 00:01:37,720
这是一只大狐猴
This is an indri.

12
00:01:40,540 --> 00:01:42,540
他和我们一样  是灵长类动物
It's a primate, like us.

13
00:01:43,540 --> 00:01:48,160
马达加斯加的这片森林就是他的家
And these forests in Madagascar are its home.

14
00:01:55,380 --> 00:01:57,150
但是要在这里生存
But to survive here...

15
00:01:58,200 --> 00:02:01,500
他不得不面对一个巨大的挑战
it has to face one major challenge.

16
00:02:07,650 --> 00:02:10,160
天堂有点拥挤
Paradise is crowded.

17
00:02:14,000 --> 00:02:16,740
每个角落都有物种栖息
Life fills every niche.

18
00:02:18,690 --> 00:02:20,850
每分每秒
And, at any one time,

19
00:02:20,850 --> 00:02:25,680
都有生命为了空间与食物斗争不已
a staggering variety of species and countless individuals

20
00:02:26,260 --> 00:02:29,450
种类繁多  数不胜数
are striving for space and food.

21
00:02:38,870 --> 00:02:40,960
和所有丛林中的动物一样
Like every jungle animal,

22
00:02:41,050 --> 00:02:44,450
大狐猴需要找到自己的方法
indri have to find their own way to survive

23
00:02:44,720 --> 00:02:47,970
才能在地球上竞争最为激烈的地方生存下去
in the most competitive place on Earth.

24
00:03:02,140 --> 00:03:08,060
丛林

25
00:03:11,780 --> 00:03:14,180
英语解说  大卫·爱登堡

26
00:03:14,190 --> 00:03:17,140
丛林错综复杂
Jungles are complex places...

27
00:03:18,250 --> 00:03:20,930
丰富的热带植物
tangled three-dimensional worlds

28
00:03:21,470 --> 00:03:24,540
交织出一个立体世界
created by lush tropical vegetation.

29
00:03:28,270 --> 00:03:33,950
这里有九成的动物在树上度过一生
90% of the animals here spend their whole lives up in the trees.

30
00:03:34,900 --> 00:03:38,940
每一种动物都有自己的生存之道
And each of them has to find its own way of getting around.

31
00:03:42,210 --> 00:03:47,020
一只蜘蛛猴悬挂于距离地面三十米高的地方
Hanging 100 feet above the ground, a spider monkey.

32
00:03:53,370 --> 00:03:55,030
他们以家庭为单位行动
They travel in family groups

33
00:03:55,030 --> 00:03:59,130
在丛林的最上层获取生存的必需品
and find everything they need in the top storey of the jungle.

34
00:04:00,840 --> 00:04:04,450
这么高的地方可不适合胆小的物种
Up here isn't a place for the faint-hearted.

35
00:04:07,630 --> 00:04:11,820
修长的四肢加上灵活如手的卷尾
With long limbs and a prehensile tail that can grip like a hand,

36
00:04:11,880 --> 00:04:13,840
他们就是为攀爬而生的
they're built for climbing.

37
00:04:20,530 --> 00:04:25,750
但是要在这么高的地方学习这些技巧
But imagine having to learn these skills as high up as this.

38
00:04:31,120 --> 00:04:35,730
三分之一的蜘蛛猴都活不到成年
One third of spider monkeys never make it to adulthood.

39
00:04:38,810 --> 00:04:42,140
这只幼崽只有几个月大
This youngster is only a few months old.

40
00:04:44,140 --> 00:04:47,950
她的未来取决于她的攀爬能力
Her future depends on her ability to climb.

41
00:04:50,500 --> 00:04:54,130
通过和哥哥姐姐在练习树上玩耍
Playing on a practice tree with her older brother and sister,

42
00:04:54,180 --> 00:04:58,160
她已经学会用尾巴当安全索
she's already learning to use her tail as a safety line...

43
00:05:01,840 --> 00:05:04,810
一切都在父亲的注视之下
under her father's close watch.

44
00:05:19,200 --> 00:05:23,630
她很想加入游戏  但是由于年纪最小
She's keen to join in the game but she's the youngest and,

45
00:05:23,630 --> 00:05:27,170
有时候不太受大家欢迎
as is the way of things, she's not always welcome.

46
00:05:33,140 --> 00:05:36,750
所以她自己找了个地方玩耍
So she chooses her own place to play.

47
00:05:42,890 --> 00:05:45,020
但是树木不尽相同
But not all trees are the same.

48
00:05:45,440 --> 00:05:49,670
这棵树需要更高的攀爬技巧
This one is for more advanced climbers.

49
00:05:59,600 --> 00:06:02,380
论积极性  毋庸置疑
Enthusiasm? Certainly!

50
00:06:08,330 --> 00:06:09,750
但论技术
Technique?

51
00:06:13,240 --> 00:06:15,220
有待提高
Room for improvement.

52
00:06:18,280 --> 00:06:21,070
此时她的几个家庭成员
Meanwhile, some of her family have moved on

53
00:06:21,070 --> 00:06:23,770
去其它地方寻找新鲜食物了
to look for a new patch of fresh food.

54
00:06:26,590 --> 00:06:29,900
树冠顶端不是幼猴该去的地方
The top of the canopy isn't for youngsters.

55
00:06:31,010 --> 00:06:35,530
可父亲没有看着她  加入大家的诱惑
But father's not looking and the temptation to join the others

56
00:06:35,530 --> 00:06:37,440
又实在无法抗拒
is irresistible.

57
00:06:45,280 --> 00:06:47,270
她必须小心翼翼
She'll need to be careful.

58
00:06:47,710 --> 00:06:51,250
从这里跌落必死无疑
A fall from here would mean certain death.

59
00:06:59,090 --> 00:07:03,560
这是她第一次独自爬到如此高的地方
It's the first time she's been as high as this on her own.

60
00:07:15,090 --> 00:07:19,680
她越爬越高  树枝越来越细
As she climbs still higher, the branches get thinner and thinner.

61
00:07:45,260 --> 00:07:47,130
尾巴救了她一命
Her tail has caught her...

62
00:07:47,970 --> 00:07:49,980
可她现在被困在空中
...but now she's stuck in mid-air,

63
00:07:49,980 --> 00:07:52,370
够不到其它的树枝
unable to reach any other branch.

64
00:08:06,270 --> 00:08:09,110
而父亲其实一直关注着
Father, however, was watching.

65
00:08:11,030 --> 00:08:12,410
他的身体强壮有力
He's big and strong enough

66
00:08:12,410 --> 00:08:14,380
可以搭成一座桥
to form a bridge with his body

67
00:08:14,500 --> 00:08:16,710
让孩子爬回安全地带
so that she can climb to safety.

68
00:08:48,700 --> 00:08:50,270
吃一堑长一智
Lesson learned.

69
00:08:56,360 --> 00:09:00,810
但是在树顶生活的不仅仅是猴子
But it's not just monkeys that live here, up in the treetops.

70
00:09:08,330 --> 00:09:10,320
如果体型足够小
And, if you are small,

71
00:09:10,550 --> 00:09:14,760
找一棵合适的树相当于找到了一生的家
finding the right tree can mean a home for life.

72
00:09:20,460 --> 00:09:22,540
这是一只飞蜥
He's a Draco lizard.

73
00:09:22,540 --> 00:09:26,640
体型只有铅笔大小  以蚂蚁为食
He's only the size of a pencil and he eats ants.

74
00:09:34,380 --> 00:09:38,620
这棵树可以为他提供一生所需的食物
This one tree could provide him with all he will ever need...

75
00:09:39,330 --> 00:09:41,730
就像回转寿司一样源源不断
a conveyor belt of food.

76
00:09:45,180 --> 00:09:47,710
这是完美的栖身之所
It's a perfect place to settle down.

77
00:09:54,810 --> 00:09:56,440
本来是的
Well, it would be...

78
00:09:58,990 --> 00:10:00,950
可这里已经有蜥蜴安家了
...but there's already someone here.

79
00:10:10,680 --> 00:10:13,940
这只大点的雄蜥蜴是这棵树的主人
This larger male is the tree's owner.

80
00:10:14,490 --> 00:10:17,100
而飞蜥从不分享
And Dracos don't share.

81
00:10:25,400 --> 00:10:28,860
主人的旗帜是个警告
The owner's flag is a warning.

82
00:10:32,240 --> 00:10:35,220
对入侵者绝不手软
Trespassers won't be tolerated.

83
00:10:37,490 --> 00:10:39,780
他不仅是在恐吓对手
The owner's not only intimidating...

84
00:10:42,150 --> 00:10:44,010
同时也做好了战斗的准备
...he's prepared to battle.

85
00:10:57,390 --> 00:10:58,730
无处可逃了
A dead end.

86
00:11:00,710 --> 00:11:03,180
形势万分危急
Safety is a long way away.

87
00:11:05,880 --> 00:11:07,490
现在他必须做出选择
Now he must choose.

88
00:11:09,470 --> 00:11:10,780
迎战
Fight...

89
00:11:14,270 --> 00:11:15,560
还是逃跑
...or flee?

90
00:11:33,340 --> 00:11:36,300
只有在丛林中你才能看到
Only in the jungle do you find lizards

91
00:11:36,300 --> 00:11:38,870
像龙一样翱翔的蜥蜴
that can soar like dragons.

92
00:11:42,710 --> 00:11:46,830
他纵身一跃可以飞出三十余米
He can travel over 100 feet in a single leap.

93
00:11:48,570 --> 00:11:52,760
这是一种高速而有效的穿越丛林的方式
It's a very fast and efficient way to move through the jungle.

94
00:12:00,480 --> 00:12:05,990
没准这会是一棵无人占领而又食物充足的树
Maybe this new tree will have food and no resident owner.

95
00:12:14,280 --> 00:12:18,390
丛林中的所有物种都在争夺生存空间
Everything in the jungle has to compete for space.

96
00:12:23,500 --> 00:12:27,120
只有百分之二的光线会到达地面
Only 2% of the sun's rays reach the ground...

97
00:12:27,740 --> 00:12:31,050
所以即使是植物也要争夺生长
...so even the plants must battle for the light they need

98
00:12:31,050 --> 00:12:32,420
所需的阳光
if they're to grow.

99
00:12:39,710 --> 00:12:44,770
三百年前这棵响盒子就开始努力汲取阳光
300 years ago, this Hura tree began its race for light.

100
00:12:46,550 --> 00:12:48,060
日复一日地
And every day since,

101
00:12:48,070 --> 00:12:51,680
它吸收着成长所需的水分和阳光
it has absorbed the water and sunshine it needed

102
00:12:51,910 --> 00:12:54,560
终于长成参天大树
to grow into a giant.

103
00:13:03,720 --> 00:13:08,370
它与其他树木一样努力生长
It has succeeded in doing what every tree must do to survive...

104
00:13:10,000 --> 00:13:12,960
终于摆脱丛林底层的昏暗  脱颖而出
...rise above the gloom of the jungle floor.

105
00:13:21,140 --> 00:13:25,770
不仅如此  它还养活了很多其它的生命
And, what is more, its success has given life to others.

106
00:13:36,250 --> 00:13:40,460
它的树枝上长着千余种植物
Its branches now carry 1,000 other plants.

107
00:13:44,200 --> 00:13:47,520
这些蕨类  无花果和兰科植物
These particular ferns, figs and orchids

108
00:13:47,520 --> 00:13:50,830
只在寄生在其他树木的树枝上
live only on the branches of other trees.

109
00:13:56,160 --> 00:14:00,410
近千种植物在一棵树上济济一堂
1,000 plants growing on one single tree.

110
00:14:02,190 --> 00:14:07,090
整片森林之中  这样的情景随处可见
Throughout the forest, this story is repeated endless times.

111
00:14:11,180 --> 00:14:13,670
正因如此  丛林中植物物种的数量
As a consequence, jungles are home

112
00:14:13,670 --> 00:14:18,100
是地球上最多的
to more species of plants than anywhere else on Earth.

113
00:14:19,050 --> 00:14:23,630
而这些植被成为大量动物赖以生存的家园
And they, in turn, support a wealth of animals.

114
00:14:29,150 --> 00:14:33,910
在厄瓜多尔  生存竞争尤为激烈
In Ecuador, the competition is at its most intense.

115
00:14:35,870 --> 00:14:39,440
在这里  光是蜂鸟就有一百种
Here, there are 100 species of hummingbirds alone...

116
00:14:42,400 --> 00:14:44,840
都在争夺花蜜
...all fighting for nectar.

117
00:14:47,310 --> 00:14:51,010
每朵花一次只能产出少量花蜜
Each flower only has a small amount at any one time,

118
00:14:51,010 --> 00:14:53,920
所以先到先得
and so it's first come, first served.

119
00:14:58,400 --> 00:15:01,700
这种蜂鸟竭尽全力
One hummingbird has gone to great lengths

120
00:15:01,890 --> 00:15:04,780
试图避免与其他物种的争斗
to avoid conflict with other species.

121
00:15:09,300 --> 00:15:14,650
刀嘴蜂鸟是唯一一种喙长于身体的鸟类
Swordbills are the only bird with a beak longer than their body.

122
00:15:17,250 --> 00:15:19,590
有些植物花冠极其细长
And some flowers are too elongated

123
00:15:19,610 --> 00:15:22,820
其它九十九种蜂鸟
for the other 99 species of hummingbirds here

124
00:15:22,920 --> 00:15:24,370
都无法吃到里面的花蜜
to feed from them.

125
00:15:37,060 --> 00:15:39,950
刀嘴蜂鸟凭借极长的喙
A swordbill's extraordinary beak, however,

126
00:15:39,970 --> 00:15:43,390
可以够到其它蜂鸟无法触及的地方
enables it to reach the places that others can't...

127
00:15:47,480 --> 00:15:52,150
也就是这种花朵基部的蜜腺
...the top of this flower, where the sweet nectar is produced.

128
00:15:53,550 --> 00:15:55,340
它找到了解决方法
It has found a solution

129
00:15:55,470 --> 00:15:58,590
不必和其它蜂鸟争夺食物
that means it doesn't have to join the fight.

130
00:16:01,310 --> 00:16:03,790
细长的花朵们竞相盛开
And, as each long flower blooms,

131
00:16:03,790 --> 00:16:08,290
为刀嘴蜂鸟提供了专属的新鲜花蜜
it gives the swordbill a fresh supply of food all to itself.

132
00:16:24,350 --> 00:16:28,710
不过  喙比身体长也是有缺点的
But having a beak longer than your body does have its drawbacks.

133
00:16:33,530 --> 00:16:36,660
首先  想保持干净就有点难度
For a start, it's tricky to keep it clean.

134
00:16:49,220 --> 00:16:53,260
更麻烦的是  要如何整理羽毛呢
Harder still, how do you preen your body feathers?

135
00:16:56,120 --> 00:16:57,730
不像其它蜂鸟
Unlike the other hummers,

136
00:16:57,730 --> 00:17:00,970
刀嘴蜂鸟的喙够不到身上的羽毛
swordbills can't reach their feathers with their beak.

137
00:17:08,920 --> 00:17:12,710
唯一的办法就是用爪子挠
The only option, a good old scratch.

138
00:17:32,030 --> 00:17:34,290
虽然不太优雅
It's a little unrefined...

139
00:17:36,560 --> 00:17:41,200
但这是独享食物要付出的一点小代价
...but a small price to pay for an exclusive food supply...

140
00:17:44,730 --> 00:17:46,810
尤其是进食时间
...especially when feeding times

141
00:17:46,810 --> 00:17:51,020
经常被暴雨天气打断的时候
are only too frequently interrupted by storms.

142
00:17:59,550 --> 00:18:02,520
丛林是地球上自然资源最丰富的地区
Jungles are the richest places on Earth

143
00:18:02,520 --> 00:18:05,120
个中原因令人惊奇
because of one remarkable fact...

144
00:18:08,280 --> 00:18:10,560
丛林能够自己制造天气
...they make their own weather.

145
00:18:16,240 --> 00:18:21,440
每天水分都会从叶表蒸发  变成水蒸气
Every day, water rises from the surface of the leaves as vapour.

146
00:18:23,410 --> 00:18:26,760
如同树木在呼出云
It's as if the trees breathe out clouds.

147
00:18:29,820 --> 00:18:33,220
水汽逐渐集结在森林上空  直到...
They gather over the forest until, finally...

148
00:18:36,000 --> 00:18:37,510
汇成倾盆大雨
...they burst.

149
00:18:52,720 --> 00:18:56,550
雨是丛林的命脉
Rain is the lifeblood of every jungle.

150
00:19:06,450 --> 00:19:10,870
动物们每天都要经受暴雨的考验
And all have to do their best to endure the daily downpour.

151
00:19:55,210 --> 00:19:58,170
有一些丛林  比如巴西的这里
In some jungles, like here in Brazil,

152
00:19:58,450 --> 00:20:02,130
由于降雨量特别大  一年中总有一段时间
it rains so much that, for part of the year,

153
00:20:02,130 --> 00:20:05,090
树木几乎被完全淹没
the trees are almost totally submerged.

154
00:20:14,160 --> 00:20:18,400
水面至林地表层深达九米
The forest floor is 30 feet below the water's surface.

155
00:20:21,580 --> 00:20:24,100
这是一个神秘的世界
This is a mysterious world,

156
00:20:24,840 --> 00:20:28,340
鲜少有人踏足
a place few people have ever explored.

157
00:20:37,170 --> 00:20:38,830
这里分布的许多动物
We have much to discover

158
00:20:38,830 --> 00:20:41,810
都值得我们去探索
about the animals for which this is home...

159
00:20:46,110 --> 00:20:51,680
有些物种你可能从未想过会在丛林里见到
...including some you might never expect to find amongst trees.

160
00:21:05,980 --> 00:21:11,310
距离海洋一千六百公里的这个地方  有江豚
Here, 1,000 miles from the sea, are dolphins.

161
00:21:16,420 --> 00:21:19,540
这种淡水豚是一个新种
A newly identified species of river dolphin

162
00:21:19,540 --> 00:21:21,790
在地球上其它地方均无分布
found nowhere else on Earth.

163
00:21:35,750 --> 00:21:37,930
由于生活在黑暗而复杂的河水里
In these black, tangled waters,

164
00:21:37,930 --> 00:21:41,100
他们的双眼几乎完全失明
they have become almost totally blind,

165
00:21:41,240 --> 00:21:42,960
所以他们游得很慢
so they move slowly,

166
00:21:43,350 --> 00:21:48,650
仔细地用声纳扫描林地表层寻找鱼类为食
carefully using their sonar to scan the forest floor for fish.

167
00:21:54,210 --> 00:21:57,930
如果这片森林里能隐居着新种江豚
If this forest can hide a new species of dolphin...

168
00:21:59,020 --> 00:22:02,600
那还会有多少新奇物种  等着我们去发现呢
...what else might there be here, awaiting discovery?

169
00:22:08,250 --> 00:22:11,100
这片泛洪丛林边缘的泥岸浅水区
At the shallow margins of the flooded jungle,

170
00:22:11,100 --> 00:22:14,250
河流穿过茂密的植被
rivers flow through lush vegetation.

171
00:22:18,150 --> 00:22:22,760
这里食物充足  养育着一些大型动物
Here, food is so abundant, it supports giants.

172
00:22:25,460 --> 00:22:28,660
水豚  世界上最大的啮齿动物
Capybara, the biggest rodents in the world...

173
00:22:34,260 --> 00:22:37,070
大水獭  体型堪比成年男性
...giant otters the size of a man...

174
00:22:42,090 --> 00:22:44,530
还有称霸河流的王者
...and the rulers of these rivers...

175
00:22:46,020 --> 00:22:47,330
凯门鳄
...caiman.

176
00:22:48,990 --> 00:22:52,260
它们体长可达三米
They grow to ten feet long and kill anything

177
00:22:52,280 --> 00:22:54,450
能杀死一切落入口中的猎物
they get between their jaws.

178
00:23:00,220 --> 00:23:03,210
然而还有更狡猾的捕猎者
But there are more artful hunters...

179
00:23:04,990 --> 00:23:08,010
从周围的森林里被吸引至此
...drawn here from the surrounding forest.

180
00:23:20,480 --> 00:23:24,840
美洲豹  丛林中顶端的捕食者
A jaguar, the supreme jungle predator.

181
00:23:32,120 --> 00:23:35,510
这条河是他领地的边界
The river marks the edge of his territory...

182
00:23:37,160 --> 00:23:40,280
但在这里  他遇到了竞争对手
...but here he has competition.

183
00:24:03,070 --> 00:24:05,980
他闯入了一只母美洲豹的地盘
He's now in the territory of a female.

184
00:24:11,790 --> 00:24:16,120
她统治这一河段已有五年之久
She has ruled this stretch of river for five years.

185
00:24:18,410 --> 00:24:21,370
这是她狩猎的地方
This is her place to hunt.

186
00:24:51,850 --> 00:24:55,170
水豚既强壮又机警
Capybara are strong and wary.

187
00:24:58,350 --> 00:25:00,710
狩猎关键在于悄无声息
The key is stealth.

188
00:25:19,340 --> 00:25:24,480
想袭击它们  她必须靠近到一米之内
She needs to get within three feet if she's to pounce.

189
00:25:47,870 --> 00:25:49,410
这次没成功
Not this time.

190
00:26:00,500 --> 00:26:02,910
她不是这里唯一的母豹
She's not the only female here.

191
00:26:04,570 --> 00:26:09,130
在丛林边缘的不同区域  各有一只母豹称后
Each part of this jungle's edge is ruled by a different queen.

192
00:26:20,330 --> 00:26:25,340
很少地方有足够的食物能养活这么多只大猫
Few places on Earth have enough food to support so many big cats.

193
00:26:52,650 --> 00:26:55,490
公美洲豹的捕猎方式则有所不同
The male hunts in a different way.

194
00:27:02,980 --> 00:27:07,650
一百三十公斤的体重  很难做到悄无声息
Weighing almost 300 lbs, it's hard to be stealthy...

195
00:27:10,630 --> 00:27:13,480
加上周围还有很多美洲豹
...and with so many other jaguars around,

196
00:27:13,850 --> 00:27:17,100
他就不费心去抓警觉的水豚了
he doesn't bother with wary capybara.

197
00:27:23,400 --> 00:27:25,890
他寻找另一种猎物
He seeks a different prey.

198
00:27:49,820 --> 00:27:54,140
他成了捕猎杀手的杀手
He's become a killer of killers.

199
00:28:21,220 --> 00:28:26,690
美洲豹的咬合力是所有猫科动物里最强的
Jaguars have the most powerful bite of any cat.

200
00:28:29,760 --> 00:28:33,040
而且他知道凯门鳄最脆弱的部位
And he knows the caiman's most vulnerable point...

201
00:28:35,360 --> 00:28:37,370
是它的后脑勺
...the back of its skull.

202
00:29:06,330 --> 00:29:10,310
在浓密的丛林底层中生活的捕猎者
Hunters living in the dense understorey of the jungle

203
00:29:10,670 --> 00:29:13,200
形态各异
come in all shapes and sizes.

204
00:29:16,050 --> 00:29:18,130
但它们有一个共同的难题
But they share a problem.

205
00:29:24,190 --> 00:29:28,460
如何分辨植物和猎物
How to tell what is a plant, and what is prey.

206
00:29:31,680 --> 00:29:34,100
这是个捉迷藏游戏
This is a game of hide and seek

207
00:29:34,320 --> 00:29:37,520
眨眼间就能定输赢
that can be won or lost in the blink of an eye.

208
00:30:09,520 --> 00:30:13,030
捕猎者和猎物之间经过漫长的斗争
The long contest between predator and prey

209
00:30:13,260 --> 00:30:17,500
形成了令人震惊的拟态水平
has produced mimicry of astounding accuracy.

210
00:30:35,280 --> 00:30:40,300
一只叶尾壁虎正伪装成地衣
A leaf-tailed gecko masquerading as lichen.

211
00:31:06,250 --> 00:31:11,040
有些动物把伪装发挥到更高境界
Some animals take camouflage a stage further still...

212
00:31:15,260 --> 00:31:17,800
在哥斯达黎加的这条小溪里
...and these streams in Costa Rica

213
00:31:17,800 --> 00:31:20,730
住着一位杰出的伪装大师
are home to one of the most remarkable.

214
00:31:31,730 --> 00:31:33,790
一只玻璃蛙
A glass frog.

215
00:31:41,640 --> 00:31:46,680
这只雄蛙尺寸迷你  只有人的指甲大小
A male, and tiny, no bigger than your fingernail

216
00:31:47,600 --> 00:31:51,340
身体几乎完全透明
and almost entirely transparent...

217
00:31:53,380 --> 00:31:55,130
这很有必要
...as he needs to be.

218
00:31:57,920 --> 00:32:01,990
几乎所有经过这里的动物  都能吃掉它
Almost everything that walks past here could eat him,

219
00:32:03,270 --> 00:32:05,000
甚至是一只蟋蟀
even a cricket.

220
00:32:09,860 --> 00:32:13,530
想活命  它就要保持静止不动
His best chance is to stay absolutely still

221
00:32:13,970 --> 00:32:16,950
希望蟋蟀的视线能直接穿透它
and trust that the cricket looks right through him.

222
00:32:39,560 --> 00:32:41,290
危险过去了
Danger passed,

223
00:32:42,830 --> 00:32:44,880
幸好如此
and that's just as well,

224
00:32:46,230 --> 00:32:49,080
因为他作为一名父亲
because he is a father...

225
00:32:52,590 --> 00:32:55,810
正在保护珍贵的卵
...and he's guarding some very precious eggs.

226
00:32:59,840 --> 00:33:03,390
过去几周  雌蛙们相继来和他交配
For the last few weeks, females, one after the other,

227
00:33:03,390 --> 00:33:07,620
并将保护后代的重任交给他
have visited him and entrusted him with their offspring.

228
00:33:10,540 --> 00:33:13,600
有些卵快孵化了
Some are now almost ready to hatch.

229
00:33:17,540 --> 00:33:21,330
叶子上有几团卵块  最上面的那一团
There are several clutches on the leaf, and those at the top,

230
00:33:21,330 --> 00:33:25,500
是最近产下的  还不到一天大
the most recently laid, are barely a day old.

231
00:33:31,210 --> 00:33:35,560
可是在丛林里  总有其它动物虎视眈眈
But in the jungle, there's always someone out to get you.

232
00:33:41,500 --> 00:33:46,450
这只黄蜂是捕食蛙卵的专家
This wasp is a specialist hunter of frogs' eggs.

233
00:33:48,240 --> 00:33:53,130
它在叶子底部发现了正在蠕动的小蝌蚪们
It's noticed the wriggling tadpoles at the bottom of the leaf.

234
00:33:58,680 --> 00:34:00,350
他决不能移动
He mustn't move.

235
00:34:01,010 --> 00:34:04,080
刚产下的卵是最脆弱的
The youngest eggs are the most vulnerable,

236
00:34:04,200 --> 00:34:06,190
他无法同时保护所有的卵
and he can't guard them all.

237
00:34:26,740 --> 00:34:30,980
但这些小蝌蚪并不像表面看起来那样无助
But these tadpoles are not as helpless as they might appear.

238
00:34:39,150 --> 00:34:43,850
难以置信的是  未孵化的蝌蚪能感应到危险
Incredibly, the unhatched tadpoles can sense danger,

239
00:34:43,850 --> 00:34:45,950
那些最成熟和最强壮的
and the oldest and strongest

240
00:34:45,960 --> 00:34:49,570
可以扭动着挣脱出来  掉进下方的溪流里
wriggle free and drop into the stream below.

241
00:35:07,720 --> 00:35:10,060
然而叶子顶部的卵
The eggs at the top of the leaf, however,

242
00:35:10,060 --> 00:35:12,940
还未能孵化
are still too young to hatch,

243
00:35:14,430 --> 00:35:17,580
但黄蜂已经知道它们的存在
and now the wasps know they're there.

244
00:35:21,280 --> 00:35:23,020
不过雄蛙的背部
But the male's back

245
00:35:23,020 --> 00:35:26,530
看起来很像新产下的卵块
looks very like the youngest cluster of eggs...

246
00:35:30,390 --> 00:35:33,700
这似乎迷惑住了黄蜂
...and that seems to confuse the wasps.

247
00:35:56,680 --> 00:36:00,400
拿自己的身体当诱饵非常冒险
Using his own body as a decoy is a huge risk.

248
00:36:01,260 --> 00:36:03,730
如果被黄蜂蛰伤  他会送命的
The wasp stings could kill him.

249
00:36:32,460 --> 00:36:36,260
他成功救下了大部分的后代
He's managed to save most of his young.

250
00:36:40,450 --> 00:36:44,500
他还得再保持警惕两周
He'll have to remain on guard for another two weeks,

251
00:36:45,640 --> 00:36:47,180
不过在丛林里
but in the jungle,

252
00:36:47,190 --> 00:36:51,560
能活过一天都算是一种胜利
just surviving the day can count as a success.

253
00:37:05,970 --> 00:37:07,670
当夜幕降临
With the coming of the night,

254
00:37:07,680 --> 00:37:12,080
另一批丛林主角们登上了舞台
a new cast of jungle characters takes to the stage.

255
00:37:15,750 --> 00:37:20,780
飞虫们开始为寻找伴侣而发光
Flying insects begin to glow as they search for mates.

256
00:37:24,810 --> 00:37:27,440
菌类与植物不同
Fungi, unlike plants,

257
00:37:27,450 --> 00:37:30,570
在阴暗的森林地面茁壮地成长
thrive in the darkness of the forest floor.

258
00:37:32,940 --> 00:37:35,450
它们隐匿起来  直到绽放的时刻
They're hidden until they begin to develop

259
00:37:35,450 --> 00:37:39,060
便以惊人的姿态生长繁殖
the incredible structures with which they reproduce.

260
00:37:41,960 --> 00:37:45,780
每株蘑菇释放出数以百万的微型孢子
Each releases millions of microscopic spores

261
00:37:45,780 --> 00:37:48,390
无形地飘散各处
that drift invisibly away.

262
00:37:53,750 --> 00:37:55,440
许多长出子实体的蘑菇
Many have fruiting bodies

263
00:37:55,440 --> 00:37:58,630
努力朝上生长  以捕捉潮湿空气中
that reach upwards to catch any feeble current

264
00:37:58,630 --> 00:38:01,240
可能存在的稀薄氧气
there might be in the clammy air.

265
00:38:05,520 --> 00:38:07,730
然而这一株  长着长着
But this one, as it grows,

266
00:38:08,600 --> 00:38:10,440
却发起了光
becomes luminous.

267
00:38:23,370 --> 00:38:27,570
蘑菇发光的原因一直是个谜团
Why fungi light up has remained a mystery...

268
00:38:34,160 --> 00:38:35,740
直到现在才被解开
...until now.

269
00:38:44,410 --> 00:38:48,270
科学家研究了世界上最亮的蘑菇
Scientists studying the brightest fungi in the world

270
00:38:48,280 --> 00:38:50,530
认为他们或许找到了答案
think they may have an answer.

271
00:38:55,720 --> 00:38:59,960
光线像灯塔一样吸引着昆虫
Like a beacon, the light attracts insects.

272
00:39:06,040 --> 00:39:08,520
从四处赶来
From far and wide.

273
00:39:16,530 --> 00:39:21,030
对这只扣头虫来说  光亮只意味着一件事...
To this click beetle,
a bright light means only one thing...millennia

274
00:39:21,290 --> 00:39:23,350
一只雌性扣头虫
a female click beetle,

275
00:39:24,860 --> 00:39:26,990
所以他亦发光回应
so he flashes in reply.

276
00:39:38,980 --> 00:39:42,280
但没有得到预期的反应
But he doesn't get the reception he was expecting.

277
00:39:47,090 --> 00:39:50,370
他疑惑不解  开始四处寻找雌虫
Confused, he starts searching for a female,

278
00:39:50,530 --> 00:39:52,730
这可帮了蘑菇的大忙
and that helps the fungus.

279
00:39:54,580 --> 00:39:59,280
当他放弃的时候  浑身已沾满了蘑菇的孢子
By the time he gives up, he's covered in the fungus's spores.

280
00:40:00,460 --> 00:40:03,230
在他继续寻找雌虫时
And, as he continues his quest for a female,

281
00:40:03,230 --> 00:40:06,950
也一同将这些孢子传播到了森林他处
he carries these spores to other parts of the forest.

282
00:40:10,310 --> 00:40:15,320
这晚  丛林中还有更奇特的东西在发光
And there are even stranger things glowing in the jungle night.

283
00:40:19,040 --> 00:40:24,670
这是火车虫（苹绕实蝇）的多彩灯光
These are the multicoloured lights of a railroad worm.

284
00:40:25,630 --> 00:40:27,640
然而它并不是一种蠕虫
It's not really a worm,

285
00:40:27,640 --> 00:40:30,910
而是一种酷似毛毛虫的有毒甲虫
but a poisonous, caterpillar-like beetle.

286
00:40:34,310 --> 00:40:38,490
黄灯亮起  以警告其他动物莫要挡道
The yellow lights warn other creatures to keep out of its way.

287
00:40:47,800 --> 00:40:51,230
它在寻找千足虫
It's hunting for millipedes.

288
00:41:01,320 --> 00:41:03,630
当它发现可疑踪迹时
When it finds the trail of one,

289
00:41:03,700 --> 00:41:06,660
便会熄灭黄灯
it switches off its yellow lights.

290
00:41:13,040 --> 00:41:17,060
现在它仅留一盏头顶的红灯
Now it only has a red light on its head.

291
00:41:22,190 --> 00:41:25,620
千足虫看不见红光
Millipedes can't see red light.

292
00:41:30,390 --> 00:41:32,870
所以对它们来说  火车虫已经
So, to them, the railroad worm

293
00:41:32,920 --> 00:41:36,730
切换成了完全隐身的潜行模式
in stealth mode is virtually invisible.

294
00:41:49,440 --> 00:41:52,680
千足虫的生命终结了
And that is the end of the millipede.

295
00:42:05,000 --> 00:42:09,240
丛林中的生存竞争迫使动物们在方方面面
Competition in the jungles forces animals to specialise

296
00:42:09,240 --> 00:42:11,370
都成了生活的行家
in every aspect of their life,

297
00:42:12,220 --> 00:42:14,270
包括求偶
including courtship.

298
00:42:16,420 --> 00:42:19,470
这也催生出了一些地球上
This has produced some of the most beautiful

299
00:42:19,480 --> 00:42:22,730
最美秒最精巧的展示
and elaborate displays on the planet.

300
00:42:28,100 --> 00:42:31,180
一只红色的雄性天堂鸟
A male red bird-of-paradise,

301
00:42:31,830 --> 00:42:35,010
正在用舞蹈来争取一只雌鸟的青睐
competing to attract a female by dancing.

302
00:42:36,820 --> 00:42:39,710
她来看看是否有佳偶在此等候
One has come to survey what's on offer.

303
00:42:58,060 --> 00:43:00,260
她是一位独立有主见的女士
She is an independent lady,

304
00:43:00,260 --> 00:43:03,890
可以任意选择自己中意的男士
and she will select whichever male takes her fancy.

305
00:43:22,110 --> 00:43:23,900
她作出了选择
She makes her choice.

306
00:43:42,830 --> 00:43:46,320
但这会儿好像又不太确定
But now she doesn't seem quite so sure.

307
00:43:54,810 --> 00:43:56,790
不行吗
No?

308
00:43:56,790 --> 00:44:00,210
可能他有点太急切了
Perhaps he's just a little too keen.

309
00:44:13,630 --> 00:44:16,530
也许明天他会好运一些
Maybe he'll have better luck tomorrow.

310
00:44:25,590 --> 00:44:29,620
红色天堂鸟在树梢间炫技求偶
Red birds-of-paradise display in the treetops.

311
00:44:32,510 --> 00:44:34,260
而家族里的其他成员
Other members of the family

312
00:44:34,290 --> 00:44:37,490
却在森林地面的阴暗处起舞
dance in the gloom of the forest floor.

313
00:44:40,240 --> 00:44:44,080
这是一只威尔逊天堂鸟
This is a Wilson's bird-of-paradise.

314
00:44:45,280 --> 00:44:49,230
他颜色艳丽  但只有麻雀大小
He's brightly coloured, but about the size of a sparrow.

315
00:44:52,660 --> 00:44:57,730
他之前大多独自生活  但现在成年了
He's lived most of his life alone, but now he's an adult,

316
00:44:57,730 --> 00:45:00,940
急需吸引一位伴侣
and he too needs to attract a mate.

317
00:45:05,130 --> 00:45:08,750
这个小光斑或许能帮到他
This little patch of light might help him do so.

318
00:45:14,870 --> 00:45:17,600
首先  他把这里收拾干净
First, he tidies things up.

319
00:45:18,120 --> 00:45:22,180
在一堆杂乱的树叶间炫耀舞技可不容易
Showing off in this jumble of leaves wouldn't be easy,

320
00:45:23,340 --> 00:45:28,620
简单的背景才更能衬托他的美丽
and his beauty will stand out better against a plain background.

321
00:45:36,290 --> 00:45:40,810
他可不希望鲜艳的叶子转移了观众的注意
He doesn't want bright leaves to divert a visitor's attention.

322
00:45:41,030 --> 00:45:43,120
它们都得被清理掉
They all need to go.

323
00:45:46,450 --> 00:45:48,470
就连绿色的也不能留
Even the green ones.

324
00:45:50,930 --> 00:45:53,450
尤其是绿色的
Especially the green ones.

325
00:46:02,890 --> 00:46:04,790
他的舞台搭好了
His stage is set.

326
00:46:05,520 --> 00:46:08,580
一个中心支柱  一点光斑
A central pole, and a little patch of light.

327
00:46:09,140 --> 00:46:10,360
完美
It's perfect.

328
00:46:14,480 --> 00:46:18,550
现在  他必须期待雌鸟能听见他的呼唤
And now, he must hope a female hears his call.

329
00:46:30,030 --> 00:46:32,520
他能在这里连等上几周
He can wait here for weeks on end.

330
00:46:42,780 --> 00:46:44,790
终于  雌鸟来了
At last, a female.

331
00:46:47,640 --> 00:46:49,950
是时候就位了
Time to take up position.

332
00:46:52,530 --> 00:46:56,280
雌鸟要通过雄鸟羽毛的光泽来衡量他
She will judge him by the brightness of his feathers.

333
00:47:02,160 --> 00:47:05,120
但为了向雌鸟展示他的最佳状态
But for the female to see him at his best,

334
00:47:05,130 --> 00:47:09,790
他需要她落座于舞台的正上方
he needs her to perch directly above his stage,

335
00:47:11,120 --> 00:47:12,730
在那束阳光下
under the light.

336
00:47:16,010 --> 00:47:19,790
这也许是他唯一一次闪耀的机会
This might be his only chance to shine.

337
00:47:26,370 --> 00:47:29,340
现在  当她垂直俯视他的时候
Now, when she's looking directly down on him,

338
00:47:29,340 --> 00:47:33,010
他只为她的目光而表演
he reveals a display for her eyes only.

339
00:47:39,250 --> 00:47:41,420
在这森林地表的阴暗处
In the gloom of the forest floor,

340
00:47:41,420 --> 00:47:45,430
他就是那最绚烂最夺目的一抹绿色
he is a dazzling blaze of iridescent green.

341
00:47:47,620 --> 00:47:50,840
森林里最耀眼的叶子
The brightest leaf in the forest.

342
00:47:59,300 --> 00:48:01,670
他成功了
And that does the trick.

343
00:48:11,650 --> 00:48:14,380
每个动物都必须找到独家方法
Each animal must find its own way of

344
00:48:14,380 --> 00:48:17,680
才能在丛林的竞争中生存下来
surviving the competition of the jungle.

345
00:48:30,880 --> 00:48:33,820
这个拥挤的世界充满了创造力
This crowded world is so full of invention

346
00:48:34,100 --> 00:48:37,500
几乎陆地上所有的物种
that almost all kinds of animals on land

347
00:48:37,660 --> 00:48:40,800
都能从这里找到起源
can trace their origins back here...

348
00:48:45,300 --> 00:48:47,350
包括人类
...including us.

349
00:48:50,700 --> 00:48:52,820
马达加斯加的这片森林
These forests in Madagascar

350
00:48:52,830 --> 00:48:56,020
是我们一位远亲的家园
are home to one of our distant cousins.

351
00:49:00,080 --> 00:49:01,800
这只雌性大狐猴
This female indri

352
00:49:01,890 --> 00:49:05,170
曾为她和家族能在森林里有一处安身之地
has fought to keep this particular patch of forest

353
00:49:05,170 --> 00:49:08,380
而英勇奋战
safe for herself and her family.

354
00:49:18,720 --> 00:49:22,100
每天清晨  家族成员们聚在一起歌唱
Every morning, the family come together to sing,

355
00:49:23,010 --> 00:49:27,570
她们在提醒别人这是她们的家园
their way of reminding others that this is their home.

356
00:49:33,810 --> 00:49:37,420
大狐猴非常适应这里的生存环境
Indri are so closely adapted to living here

357
00:49:37,650 --> 00:49:40,630
以至于现在已无法生存于别处
that now they can live nowhere else.

358
00:49:44,340 --> 00:49:46,980
对她们以及其他数十亿
For them and the billions of animals with whom

359
00:49:46,980 --> 00:49:48,680
共享家园的动物来说
they share their home,

360
00:49:49,720 --> 00:49:52,810
丛林是个庇护所
the jungle is a sanctuary.

361
00:49:56,900 --> 00:49:58,770
然而一切正遭受着变故
But this is changing.

362
00:50:02,980 --> 00:50:07,060
在家族首领出生的这十年里
Even in the ten years since the head of this family was born,

363
00:50:07,070 --> 00:50:11,270
仅在马达加斯加  就有一百万公顷的雨林
one million hectares of the rainforest have been destroyed

364
00:50:11,340 --> 00:50:13,520
遭到破坏
in Madagascar alone,

365
00:50:14,970 --> 00:50:19,210
而那里曾栖息着半数的大狐猴家族
and, with it, half the indri families that once lived there.

366
00:50:24,740 --> 00:50:28,230
当地居民说  大狐猴是我们的兄弟
The local people say the indris are our brothers

367
00:50:28,230 --> 00:50:32,250
他们的歌声也是在提醒我们
and their song is a call to remind us that we, too,

368
00:50:32,250 --> 00:50:34,370
人类也曾经依靠丛林为生
once depended on the jungle.

369
00:50:43,500 --> 00:50:48,230
这片伊甸园仍是充满奇迹和魔法的天堂
This Eden is still a place of wonder and magic.

370
00:50:53,460 --> 00:50:57,510
有些生命  毋庸置疑  值得我们保护
Something, surely, worth protecting.

371
00:51:08,440 --> 00:51:09,500
下一集
Next time...

372
00:51:09,710 --> 00:51:13,640
极端的生存环境把生命推向极限
A land of extremes that pushes life to the limit.

373
00:51:15,450 --> 00:51:17,080
动物们自有非同寻常的方法
Animals have extraordinary ways

374
00:51:17,080 --> 00:51:19,660
来应对险恶的生存环境
of dealing with the hostile conditions.

375
00:51:21,160 --> 00:51:25,790
由此创造出了地球上最伟大的生存壮举
Creating the most epic survival stories on Earth.

376
00:51:25,940 --> 00:51:27,990
这就是沙漠
These are deserts.
