1 . The diversity of Australian animals in NSW national parks is extraordinary. Some common species can be found across a range of parks, while others are endemic (特有的) to a specific area. Our national parks are also important shelters for threatened animals, many found nowhere else in the world. The following are some examples.

Albert’s lyrebird

The Albert’s lyrebird is much rarer than the superb lyrebird. Distinguished by its richer brown feather and less delicate tail feathers, it’s protected as a threatened species in NSW.

Cumberland Plain land snail

The endangered Cumberland Plain land snail is only found on the Cumberland Plain, west of Sydney. During drought it digs deep into the soil to escape severe conditions. Its brown shell is thin and fragile (脆弱的).

Australian fur seal The largest fur seal, Australian fur seals are found in isolated rocky outcrops and islands along the NSW coast. They come ashore to form breeding colonies (繁殖地) and can often be seen at Barunguba Montague Island Nature Reserve.

Australian brush turkey

The Australian brush turkey, also known as bush or scrub turkey, can be found in rainforests along eastern NSW. With a striking red head, blue-black feather and booming call, these distinctive Australian birds are easy to spot while bird watching in several NSW national parks.

3 . New research paints a lifestyle picture of the beloved pandas in China’s Wolong Nature Reserve, and the new study indicates pandas are around others more than previously thought. They use scent (气味) marking to keep track of both family members and friends, leave updates about life events, and check out the dating scene.

Thomas Connor, lead author of the study, spent months watching for signs of pandas. “Once you’ve gotten an eye for it, you can see on hill tops and different trails the scent-marking trees, and the pandas seem to be doing this a lot,” Connor says. “It is pretty evident that they are exchanging information through scent marking behavior.”

To link the marked trees with an understanding of panda’s social structure, the researchers needed to document nearby panda communities. Connor teamed up with coauthor Ken Frank who said, “I told him that once he has data on which pandas are close to each other, we can use the techniques and theories that apply to humans to understand their social networks. And these scent trees are a social media. Like Facebook, you don’t have to be in the same place at the same time. It allows one to broadcast to many, and it’s a record.

Connor dug into a wealth of data he had collected in the form of fresh panda waste, which is the gold standard of panda watching. Information from the waste allowed them to identify specific pandas in the area around the scent-marking trees, and showed if these pandas were related to each other.

The discoveries in this study show that pandas are a part of coupled human and natural systems where humans share their habitat. Anything about how they live and what they need can ultimately help inform good conservation policies and maybe understand our own behavior a little more.

4 . The Mysterious World of Deep-Sea Creatures

The deep sea remains one of the least explored and understood environments on our planet. Lying below the sunlit upper layers of the ocean, the deep sea is a region of permanent darkness, freezing temperatures, and massive pressure. Yet, life thrives (茁壮成长) here in some of the most astonishing ways.

* The Black Dragonfish *

Residing at dephs of up to 2,000 meters, the black dragonfish is a predator with a thin and long body and sharp teeth. What makes it unique is its ability to produce its own light, a phenomenon known as bioluminescence. This helps it attract prey (猎物) and communicate with potential mates.

* The Giant Squid *

Long a stuff of legends and tales, the giant squid, which occasionally attacks whales, can reach lengths of up to 43 feet. Its massive eyes, the size of dinner plates, allow it to detect weak light in the deep dark waters. Encounters with this enormous creature are rare, and much of its life remains unknown.

* Tube Worms at Hydrothermal Vents *

In the depths of the ocean, hydrothermal vents (热液喷口) shoot superheated water packed with minerals. Around these vents, communities of tube worms thrive, reaching lengths of up to 2 meters. They possess no mouth or digestive system; instead, bacteria inside them process the minerals from the vents to produce energy.

Modern technology has enabled humans to explore deeper into the ocean than ever before. Using remotely operated vehicles and deep-sea submersibles (潜水器), scientists can now study these creatures in their natural habitats, uncovering secrets that could hold the key to understanding life’s adaptability.

6 . African penguins live on the rocky coasts of South Africa, Namibia and nearby islands. Like other types of penguins, the birds have white feathers covering their chests and black feathers covering their backs. They form lifelong pair bonds with mates, but they nest in huge colonies — so, scientists wondered how the birds were able to identify their partners among the sea of black-and-white birds. They wondered if their chest spots had something to do with it. To test this theory, they studied 12 African penguins at a zoo and marine park near Rome called Zoomarine Italia.

In one test, they hung two life-size photographs of the African penguins. One showed a random member of the colony, while the other showed the test subject’s mate. The scientists recorded the birds’ interactions with the photos: How long did they spend looking at each one, as well as how much time did they spend standing near each photograph? The penguins spent more time gazing at the photo of their partners — about 23 seconds longer, on average — than looking at the other photo. They also stood next to the image of their beau s for twice as long. Then, the researchers covered up the heads of the birds in the photographs, leaving only their speckled bodies visible, and the penguins still lingered near their partners’ portraits.

In another experiment, the researchers hung up two photos of a bird’s mate — but, in one, they had digitally removed its spots. In this case, the penguin again spent more time looking at the photo with the dots.

Finally, the researchers posted two photographs of penguins with digitally removed spots — one of the test subject’s mate and the other of a random penguin from the colony. In this scenario, the penguins did not appear to recognize their partners. They spent roughly the same amount of time gazing at or standing near both photos.

Together, the results of these experiments suggest African penguins are zeroing in on their partners’ spots and using them like name tags, scientists say.

“Our results provide the first evidence of a specific visual cue responsible for spontaneous individual recognition by a bird and highlight the importance of considering all sensory modalities in the study of animal communication,” the researchers write in the paper.

7 . Hiking is tricky when you’re carrying a threatened species. Ally Whitbread carefully walked through the wilds while carrying a cooler full of small, rare snails —the Chittenango ovate amber snails.

“I feel like I’ve got 500 babies to take care of—just like a very crazy mother hen,” she said. Whitbread is part of a team transporting a lab-grown population to a new, remote home. The snails are facing extinction —only dozens are estimated to remain at one waterfall in upstate New York. “Such a recovery process can take years to decades. There are several things remaining to be unlocked during the process —what the action is going to bring, what role that species might play, and whether they might live well. We are just racing to better understand our planet’s biodiversity before the species die out.”

It took the scientists years to raise this population in the lab. The hike to a hidden waterfall is a chance to examine what makes them grow well in the wild, or what doesn’t. The snails don’t have any known unique features critical to humans, and it’s been a long journey just to attempt to save them. These efforts could figure out their hidden benefits.

Specialist Cody Gilbertson said the drive to save them can go deeper, not just the love for science. The creatures are no bigger than a fingertip and look up at their caregivers. “You know their big eyes are staring at you, like —there’s no way that you’re not going to kind of fall in love,” Gilbertson said.

Dropping them off at their new waterfall home wasn’t even the end —it’ll be another 5 years before the team knows whether the snails can survive there. They’ll go for a hike twice a month to track their progress.

10 . An ancient Latin proverb says “Aquila non capit muscas” —cagles don’t hunt flies—meaning that important ones shouldn’t concern themselves with small, insignificant matters.But the lions in East Africa should concern themselves with the seemingly insignificant ants, because these ants are changing their lifestyles.

The story starts with the acacia trees(金合欢树)in an African wildlife area in central KenyaSome of these acacia trees provide food and shelter for specific ant species, which in turn defend the tree against herbivores(食草动物).The ants are actively attacking and driving away herbivores that attempt to feed on the tree’s leavesThis is highly effective; the ants not only physically harm the herbivores but also release chemicals that can deter other potential attackers.

But these ants are in trouble.Another species called the “big-headed” ant is destroying entire groups of tree-protecting ants.This, in turn, sets off an entire chain of events that ends up influencing when and how lions can hunt.

This ant invasion(入侵)affects one thing after the other.It leaves the acacia trees defenseless against herbivores especially elephants.The elephants come in and eat the acacias at five to seven times the rate observed in uninvaded areas.The lions, while hunting for food, have no more trees to use for hiding.This reduced tree cover makes lions less successful at hunting and pushes them to find different areas to hunt in．

“These tiny invaders are pulling on the ties that put an African ecosystem together, determining who is eaten andwhere,” said Todd Palmer, an ecologist from Florida.

The lions, which are already endangered, are managing to cope with this by no longer focusing their attention on zebras.The zebras, of course, can see them much better on the approach given the lack of cover.Instead, they are targeting water buffalo.But this also isn’t the end of the story.Who knows what the lions’ changing strategy will mean for the ecosystem down the line?
