[00:00:48] Ten thousand years ago, the ever-changing, meticulously crafted blocks
[00:00:52] of the Ailao Mountains were assembled on the map of southern China, creating
[00:00:56] a unique green home in the world's temperate
[00:00:59] zones. Ailao Mountain.
[00:01:03] 。
[00:01:06] Countless creatures crossed mountains and rivers, and once again
[00:01:10] landed. They respond to
[00:01:14] challenges with ingenious strategies. They continue their lineage through continuous
[00:01:18] evolution, and communicate their intentions with unique songs.
[00:01:21] The low buzzing ghost-faced day hawk,
[00:01:24] the Ailao Mountain squirrel with whiskers,
[00:01:27] are extremely rare.
[00:01:45] Follow the traces of life and step into this hidden realm to
[00:01:48] unravel the codes of life
[00:01:51] that span billions of years.
[00:01:53] 。
[00:03:33] Wow, the bark here is so hard, I can't move it. Let me look
[00:03:37] over here. It seems there are some
[00:03:41] small beetles
[00:03:42] here.
[00:03:45] Ailao Mountain has a continuous low-altitude ecological system from tropical
[00:03:49] to temperate zones. It provides diverse
[00:03:53] habitats for insects and is an ideal
[00:03:56] place for scientists to study their evolutionary codes.
[00:05:00] And also Jun A . Various
[00:05:03] kinds of beetles are hidden in different corners. To
[00:05:07] find them, in addition to careful observation, multiple methods
[00:05:10] are also needed.
[00:06:14] Taking advantage of the clear weather, the expedition team followed the stream
[00:06:18] to find another kind of natural spirit, butterflies
[00:06:21] . Every year, at the turn of spring and summer, a
[00:06:24] butterfly larva in the valleys of Ailao Mountain
[00:06:28] transforms into a pupa and flutters .
[00:06:32] Having wings and conquering the sky is a key
[00:06:36] factor for many insects to thrive in the earth's evolution for ten thousand years
[00:06:39] until now .
[00:06:42] Therefore, understanding the mystery of flight is also
[00:06:45] an important research topic for the academic team.
[00:07:03] So beautiful
[00:07:05] . We saw
[00:07:09] it.
[00:07:42] let's do it here.
[00:07:45] Deep in Ailao Mountain, coexisting with butterflies are a large number
[00:07:49] of moths . They
[00:07:51] are warriors of the night, possessing unique survival strategies
[00:07:55] . This investigation, another important task
[00:07:59] of the expedition, is to collect specimens of various
[00:08:02] moths. It's relatively flat
[00:08:05] here,
[00:08:12] Hmm.
[00:08:26] They set up a light trap on an open hillside.
[00:08:29] 。
[00:08:32] As night falls, the bright light attracts moths and other insects
[00:08:35] to
[00:08:36] come.
[00:08:41] Come, come and see.
[00:09:42] So big, I feel like I've never seen one this big , I think the ones I saw before were all very small
[00:09:46] . It's like a leaf
[00:09:48] .
[00:09:53] A rich variety of insects breed and thrive in the dense
[00:09:57] forest, forming a complex and delicate ecological network
[00:10:01] .
[00:10:08] Many endemic amphibians and reptiles also inhabit
[00:10:12] here.
[00:11:56] It is named after being first discovered in Ailao Mountain.
[00:12:16] They do not miss any corner where the Ailao salamander might be hiding. Suddenly, Rao Dingqi made a discovery
[00:12:18] .
[00:13:01] The color of the Ailao salamander tadpoles
[00:13:04] blends with the surrounding environment
[00:13:07] . This camouflage allows them to escape predators
[00:13:14] . During the subsequent two-year growth period
[00:13:17] , these tadpoles will face countless survival challenges
[00:13:22] . Only a few will develop into adults
[00:13:42] . These thick black spines can be used as weapons
[00:13:45] to fight for mates.
[00:13:48] 350 million years ago, amphibians successfully broke
[00:13:52] free from the shackles of water and bravely set
[00:13:56] foot on land, opening up new living
[00:13:59] spaces. Yet they always maintained a deep
[00:14:02] connection with water. This unique adaptability allowed
[00:14:06] them to continue to this day in a changing
[00:14:09] environment.
[00:14:12] The Ailao Mountain frog lays its eggs in winter, so it goes
[00:14:16] into the water in winter. Normally, it is not in the water, it will look
[00:14:20] for a partner to hide or forage on the mountain.
[00:14:23] 。
[00:15:18] They appear at night and forage
[00:15:21] in the forest.
[00:16:37] Although Rao Dingqi and his team did not find the mysterious Ailao
[00:16:41] salamander , they did
[00:16:43] record a lot of frog activities, accumulating valuable
[00:16:47] data for subsequent research.
[00:16:49] 。
[00:16:53] The dense primeval forests of Ailao Mountain provide
[00:16:57] a humid and sheltered living environment for amphibians
[00:17:01] and reptiles. Ailao Mountain toad.
[00:17:04] Red-footed salamander.
[00:17:07] Bamboo leaf green. In Ailao Mountain, every organism
[00:17:11] has its unique way of survival. They are interdependent
[00:17:15] and jointly maintain the balance of this
[00:17:18] forest.
[00:17:21] And above them lives a kind of tree-dwelling
[00:17:25] spirit
[00:17:25] .
[00:17:30] Qingchen, the sleeping Ailao Mountain is awakened by
[00:17:34] crisp calls. This is
[00:18:00] In the dense forest, they follow the calls, searching for movement among the trees.
[00:18:02] 境
[00:18:07] 。
[00:18:14] A little slower, I said.
[00:18:16] Okay, this wood is a bit soft.
[00:18:19] We usually need to go to high places because it's easier to determine their direction from high places.
[00:18:26] If you hear it in the valley, it feels like the calls are coming from all directions, so it's hard to tell their direction.
[00:18:39] August
[00:18:40] 2024
[00:18:44] From the bright mountains
[00:18:47] , they began to observe their daily life.
[00:18:56] Black gibbons are named for the black fur on their heads.
[00:19:03] There are about 1,500 black gibbons globally
[00:19:08] , which is even rarer and is a critically endangered species in the world
[00:19:11] . They spend most of their time foraging
[00:19:15] in the canopy or middle layers of tall
[00:19:18] trees and rarely come to the ground,
[00:19:22] making them typical arboreal small primates, known
[00:19:25] as "tree spirits"
[00:19:26] .
[00:19:36] Rested.
[00:19:44] The dense primeval montane monsoon evergreen broadleaf forest here provides
[00:19:47] them with a good habitat and abundant food.
[00:21:40] The population of these animals is constantly increasing, and their distribution area is also continuously expanding. In the middle section of Ailao Mountain, another group of scientific
[00:21:43] researchers is protecting an even larger
[00:21:47] animal population .
[00:21:52] There are still many kinds of magpies in that area
[00:21:55] . Like the white-headed magpie, the western
[00:21:59] magpie, there are many kinds in this
[00:22:01] area.
[00:22:04] Zhao Xuebing and his colleagues went to the Jinshan
[00:22:08] Pass bird banding monitoring station in the middle of Ailao Mountain
[00:22:12] to prepare for the autumn migration of birds and
[00:22:15] high winds.
[00:22:53] On the global migratory bird map, East
[00:22:57] Asia-Australia is a very
[00:22:59] busy route. Ailao Mountain
[00:23:03] is located on this life corridor. Every
[00:23:07] autumn, flocks of migratory birds fly from the distant
[00:23:10] north. When they encounter the Qinghai-Tibet Plateau, this natural
[00:23:14] barrier, they turn to the mountains
[00:23:18] in the southeast. Ailao Mountain is thus
[00:24:27] . Except for some large birds that
[00:24:30] will soar during the day, most migratory birds, in order to avoid
[00:24:34] predators, usually choose to start their
[00:24:37] blood journey after night falls. For
[00:24:41] this reason, Zhao Xuebing and his team attract migratory birds to
[00:24:45] come with lights, based on the phototactic instinct
[00:24:48] of birds.
[00:25:20] Someone must be on duty at this net at all times, because once a bird is caught in the net
[00:25:23] , it needs to be taken out immediately to ensure the bird's safety
[00:25:27] . Zhao Xuebing and the staff of the monitoring
[00:25:31] station put the rescued migratory birds into special cotton
[00:25:34] cloth bags to prevent them from being injured
[00:25:38] .
[00:25:44] So when we put it in this kind of bag, it will be relatively
[00:25:48] quieter.
[00:26:29] F1087498
[00:26:33] Zhao Xuebing and his team began to measure, sample,
[00:26:37] and band the captured migratory birds, as well as
[00:26:41] other tasks, in order to better track their migration
[00:26:44] routes and survival status
[00:26:47] .
[00:26:49] The migratory birds that pass through Ailao Mountain actually come from a very wide range. The entire
[00:26:53] region of Siberia in Russia will have them come over.
[00:26:57] From the northeast of the country to the northwest and central, this area
[00:27:01] will have them come over.
[00:27:32] The collared scops owl is a small
[00:27:36] raptor. Its plumage is very similar
[00:27:40] to tree bark. When it stands still, it looks like a piece of wood
[00:27:43] . This effectively confuses predators and
[00:27:47] allows it to conceal itself and ambush prey
[00:27:50] . These two are also very
[00:27:54] good at mimicking branches or leaves
[00:27:57] .
[00:28:32] It has not only greatly enriched our country's bird research resource library
[00:28:36] , but also laid a solid data foundation for in-depth
[00:28:40] exploration of major scientific questions such as the migration patterns
[00:28:44] of migratory birds in
[00:28:45] the Ailao Mountain area.
[00:28:49] Ailao Mountain, this green barrier spanning
[00:28:53] southwest China, is not only a geographical
[00:28:57] boundary, but also a sanctuary for wildlife
[00:29:00] . It is.
[00:29:14] The tracking and deciphering by scientific researchers has given this natural
[00:29:17] treasure trove new meaning. In this mysterious
[00:29:21] and turbulent land, every unique existence
[00:29:25] is the essence of ten thousand years of evolutionary wisdom
[00:29:29] . Every analyzed data connects the past
[00:29:35] and the future. And the journey of exploration and guardianship
[00:29:38] continues.
[00:32:16] The higher you stand,
[00:33:36] Hello everyone, and welcome to a brand new day. Good morning, viewers.
[00:33:39] Good morning, everyone. This is the morning program of China Central Television Comprehensive Channel and News Channel,
[00:33:43] broadcast live simultaneously.
