1 . The world’s largest ape Gigantopithecus blacki (G. blacki) vanished from Earth between 295, 000 and 215, 000 years ago, more than 100, 000 years earlier than once thought, pushed to extinction as the environment around it shifted, researchers reported recently in Nature.

The fate of G. blacki, twice the size of the largest modern apes and resembling a super-sized version of its close cousin, the orangutan, has long been a mystery. For about 2 million years, G. blacki inhabited a landscape of forests and grasses in what’s now southern China. It left behind only scattered remnants: thousands of teeth and four jawbones, unearthed in cave sediments in the region.

To establish a chronology for the ape’s extinction, paleoanthropologist Yingqi Zhang of the Chinese Academy of Sciences in Beijing and his colleagues used different dating techniques to determine the ape’s habits, diet and environment. In the teeth, they looked for data on the ape’s diet, measuring isotopes (同位素) of carbon and oxygen as well as examining the teeth for tiny evidence of wear and tear — which can reveal not only diet, but also give hints of repeated behaviors and stress. The team also analyzed the cave sediments bearing the fossils, hunting for fossil pollen and conducting luminescence dating (光释光测年) on radioactive elements within the sediments.

The team’s reconstruction revealed that — around 700, 000 to 600, 000 years ago, southern China shifted from its forested landscape to a more seasonally-driven environment. Some apes, including the orangutans, were able to adapt to these changes. But G. blacki was unable to change rapidly enough, and its numbers slowly dwindled before going extinct, the team suggested.

The assembled evidence told a convincing story that “the extinction of G. blacki coincided in southern China with a decrease of forest cover and expansion of savanna-like environments,” said Hervé Bocherens, a biogeologist at the University of Tuebingen in Germany. Still, he said, documenting the extinction of this species from the fossil record is tricky — and it’s impossible to rule out the possibility that pockets of G. blacki may have lingered in still-undiscovered caves for longer.

2 . Ten years ago, environmental journalist Ben Goldfarb was on a reporting trip about wildlife conservation. When he was shown around some new animal crossing structures near, Missoula, these new bridges and tunnels intrigued him. He was attracted by these beautiful human-built structures and inspired to write a book. Crossings: How Road Ecology Is Shaping the Future of Our Planet has now been published.

Through expert interviews, in-depth research and convincing analysis, Goldfarh brings to life the deadly consequences our 40 million miles of roadways have had and are having on the natural world and the creatures that inhabit it. A million animals are killed by cars each day in the US alone. Road salt pollutes lakes and rivers. And there's the barrier effect-the steady stream of traffic that prevents animals from migrating (迁徙) all together and finding habitats. Goldfarb writes that noise pollution is the most worrisome among all the road's ecological disasters. Both the engine noise and the tire noise greatly impact ecological environment.

Figures on deaths and disruptions (扰乱) are disheartening, but Goldfarb vividly describes how scientists are actively working on meaningful improvements to help animals and roads better coexist, such as wildlife crossings, from passages in Canada's Banff National Park to the famous Liberty Canyon Overpass in Los, Angeles. Another example is that in India, they built a new highway through a tiger reserve so that animals can come and go underneath the lifted freeway. Of course, that made the project more expensive, but it's ecologically the right thing to do.

Crossings is a truly important and landmark book on a subject whose full impacts continue to be disregarded or underestimated in considering conservation efforts. The book is a sympathetic, heart-warming guide to exploring the issues of wildlife survival and our own.

3 . Falcons are powerful birds that may be trained to hunt in cooperation with humans. The art of training falcons as “hunting dogs of the skies” is called falconry (训鹰术). It was developed in the ancient Arabian Desert around 4000 B. C. In the past, falconry mainly involved hunting with falcons to supplement one’s diet. But now, it has become the favorite sport and pastime in the Arabian Peninsula.

Falconry includes three major processes: acquiring the falcons, training them, and hunting with them. Every year, falconers begin capturing wild falcons in June and July, the migration season. The best birds to catch are the ones with naturally nurtured hunting skills, aged one or two years. Once the falcons are captured, their heads are immediately covered with a leather hood. This is essential because they imprint as their master whomever they see first after the hood is removed. Right after a bird is caught, the training process starts. It begins by depriving (剥夺) the bird of food to make it easier to tame. The birds are taught to know their own name and respond to their master when called. Arab falconers live with their birds day and night in order to build a strong relationship with them.

By the end of October or mid-November, the trained falcons are ready to hunt in the desert. They have excellent vision, 2. 6 times greater than that of a human. They are also the fastest divers on the planet. One hunting technique that sets them apart from other animals is that they can be trained to deliver their prey, without killing it first. This is vital in Islamic culture because animals used for food must still be alive to ensure that the meat is halal, that is, properly prepared according to Islamic law.

Falcons have played such a crucial role in traditional Islamic cultures that a number of countries in the Middle East have made them their national bird. Falconry has grown so popular that specialist hospitals have been established to take care of these magnificent birds. Falcons are even issued their own passports. They are the only animals in the United Arab Emirates that are legally allowed to travel inside planes, enjoying a level of luxury that some humans can only dream of.

4 . One Saturday in June, I got off the train from Vienna at Altenberg station, in the midst of a gathering of bathers, such as often flock to our village at fine weekends.

I had gone only a few steps along the street and the crowd had not yet scattered when, high above me in the air, I saw a bird whose species I could not at first determine. It flew with slow, measured wing-beats, varied at set intervals by longer periods of gliding. It seemed too heavy to be a hawk; for a stork (鹳), it was not big enough and, even at that height, neck and feet should have been visible. Then the bird made a sudden turn so that the setting sun shone for a second full on the underside of the great wings which lit up like stars in the blue of the skies. The bird was white. By Heaven, it was my cockatoo (凤头鹦鹉)! The steady movements of his wings clearly indicated that he was setting out on a long-distance flight.

“What should I do? Should I call to the bird?” Well, have you ever heard the flight-call of the greater cockatoo? No? But you have probably heard pig-killing in the traditional method. Imagine the loudest long cry a pig could make, picked up by a microphone and amplified many times over by a powerful speaker. A man can imitate it quite successfully, though somewhat weak, by shouting at the top of his voice “O-ah”. I had already proved that the cockatoo understood this imitation and promptly “came to heel”. But would it work at such a height? A bird always has great difficulty in making the decision to fly downwards at a steep angle. To yell, or not to yell, that was the question. If I yelled and the bird came down, all would be well, but what if it sailed calmly on through the clouds? How would I then explain my song to the crowd of people?

Finally, I did yell. The people around me stood still, rooted to the spot. The bird hesitated for a moment on outstretched wings, and then, folding them, it descended in one dive and landed upon my outstretched arm. Once again I was master of the situation.

5 . Thanks to the 1999 Environment Protection and Biodiversity Conservation Act, 26 endangered species in Australia have seen their populations recover.

It seems like that we're always hearing about new animals that have become endangered, but there's some good news in Australia: 26 animal species no longer meet the criteria to be listed as threatened. Australia’s biodiversity has been in decline, with more than 1, 700 species and ecological communities known to be on the line. In 1999, the Environment Protection and Biodiversity Conservation (EPBC) Act was passed to introduce protections for endangered animals. The burrowing bettong is one of 26 Australian species that have returned from the edge of extinction.

Seemingly these are working, as a recent study published in the journal Biological Conservation reviewed the animals that were previously or currently listed as threatened between 2000 and December 2022, and discovered that 26 species had recovered to no longer meet the criteria. Species that have seen improvement include the charmingly named burrowing bettong, the golden bandicoot and the bulloo grey grasswren.

Factors behind this improvement include habitat management, control of introduced predators (捕食者) and translocation of endangered animals to predator-free islands. However, the species have not been officially delisted at this time. The EPBC Act only allows species to be delisted if doing so will not have a negative effect on their survival, and researchers believe that conservation gains could be lost should management efforts be stopped.

Dr Michelle Ward, a conservation scientist at WWF Australia, told The Guardian, “The key problem with delisting species is that then they no longer have monitoring and no longer need certain funding plans.”

However, it is promising that researchers have found signs of improvement. Hopefully this will continue among these and other species!

6 . Safe Haven for Donkeys (驴) is providing sanctuary for rescued working donkeys in the El Saf region of Egypt.

First established in 2000 to help thousands of working donkeys in Israel, the charity Safe Haven for Donkeys has begun working with an Egyptian partner organization, the Bridge Foundation, to provide care to the donkeys in the El Saf region of Egypt.

Thousands of donkeys work in the brick kilns (窑) in Egypt, carrying 1.4 to 1.6 tonnes of bricks and moving at an intense pace to prevent unfired bricks from cracking in the heat. Due to lacking expert veterinary (兽医的) care, many of these animals are suffering intense pain from harness wounds, beatings, hoof issues and parasitic diseases spread by flies.

Now the cooperation between UK charity Safe Haven for Donkeys and Egyptian community development charity the Bridge Foundation is providing much-needed relief to these animals. The project includes a mobile veterinary clinic which treats common injuries and infections and trains the owners in how to best look after their donkeys.

In a press release, Andy Foxcroft, CEO of Safe Haven for Donkeys, said, “Through our work in Israel, we came to know of millions of working animals in Egypt without critical veterinary care. They were suffering a host of preventable and treatable painful conditions. Currently. no other animal welfare charity provides veterinary interventions in these particular kilns. So the skills of this charity are needed to treat sick and injured animals and provide training for owners and local professionals (vets and farriers). The first year is vital as we hope to make a lasting impact by reducing the unnecessary suffering of working animals. which sadly, is all too common a feature in the brick kilns.”

Safe Haven for Donkeys’ work, which helps about 10,000 animals a year, is made possible by charitable donations that fund the treatment and training they offer. You can make a donation on its website.

7 . Kruger National Park is, in a word, life-changing. One of the top attractions in South Africa, and one of the largest national parks in the world, Kruger National Park is a must for any wildlife lover.

Kruger National Park Animals

Nothing will prepare you for the huge volume of wildlife that you’ll be able to see in Kruger National Park. The park is home to 114 different species of reptiles; more than 500 species of birds; and 147 mammals. Not only will you have the opportunity to see the Big Five (lion, leopard, buffalo, elephant, and rhino), but you’ll see tons of other mammals like zebras, giraffes, hyenas, hippos, impalas, and many more.

When is the Best Time to Visit Kruger National Park?

The driest months being June, July, and August are the best time of year to visit the park, when the days are sunny and warm and the nights are cooler. Many trees and shrubs have lost their leaves, and water sources dry up, making it easier to spot game around the remaining waterholes.

Driving in Kruger National Park

What makes Kruger National Park unique from other parks is that it is accessible via self-drive. Many people who come to the park come with their own vehicle because it’s considerably more affordable than taking a guided tour. Doing a self-drive safari (游猎) also gives you more flexibility with your timing.

9 . Birders get nervous when they see landscapes covered in wind turbines (涡轮机). When the wind gets going, their blades (叶片) can turn around at well over 200km per hour. It is easy to imagine careless birds getting cut into pieces and wind turbines do indeed kill at least some birds. But a new analysis of American data suggests the numbers are negligible, and have little impact on bird populations.

Erik Katovich, an economist at the University of Geneva, made use of the Christmas BirdCount, a citizen-science project run by the National Audubon Society. Volunteers count birds they spot over Christmas, and the society gathers the numbers. He assumed, reasonably, that if wind turbines harmed bird populations, the numbers seen in the Christmas Bird Count would drop in places where new turbines had been built. Combining bird population and species maps with the locations and construction dates of all wind turbines, he found building turbines had no noticeable effect on bird populations.

Instead of limiting his analysis to wind power alone, he also examined oil-and-gas extraction (开采), which has boomed in America over the past couple of decades. Comparing bird populations to the locations of new gas wells revealed an average 15% drop in bird numbers when new wells were drilled, probably due to a combination of noise, air pollution and the disturbance of rivers and ponds that many birds rely upon. When drilling happened in migration centers, feeding grounds or breeding locations, bird numbers instead dropped by 25%.

Wind power, in other words, not only produces far less planet-heating carbon dioxide and methane than do fossil fuels. It appears to be significantly less damaging to wildlife, too. Yet that is not the impression you would get from reading the news. Dr Katovich found 173 stories in major American news media reporting the supposed negative effects that wind turbines had on birds in 2020, compared with only 46 stories discussing the effects of oil-and-gas wells.
