1 . Research led by ecologist Bart Hoekstra of the University of Amsterdam shows that birds are affected by the mass use of fireworks on New Year’s Eve up to a distance of 10 km (6 miles) away.
With data from weather radars and bird counts an international team of researchers revealed how many birds take off immediately after the start of the fireworks, at what distance from fireworks this occurs and which species groups mainly react. “Birds take off as a result of an acute flight response due to sudden noise and light. We already knew that many water birds react strongly, but now we also see the effect on other birds throughout the Netherlands, ”says ecologist Bart Hoekstra of the University of Amsterdam. In the scientific journal Frontiers in Ecology and the Environment, the researchers therefore argue for large fireworks-free zones.
Last year, other researchers at IBED discovered that geese are so affected by fireworks that they spend an average of 10% longer looking for food than normal during at least the next 11 days. They apparently need that time to restore their energy to their former condition, after fleeing from the fireworks.
Because 62% of all birds in the Netherlands live within a radius of 2. 5 km of inhabited areas, the consequences of fireworks are high for all birds throughout the country. “Flying requires a lot of energy, so ideally birds should be disturbed as little as possible during the cold winter months. Measures to ensure this are especially important in open areas such as grasslands, where many larger birds spend the winter. The effects of fireworks on birds are less pronounced near forests and semi-open habitats. In addition, smaller birds such as tits and finches live there, which are less likely to fly away from disturbance.”
The authors argue for fireworks-free zones in areas where large birds live. Hoekstra: “These buffer zones could be smaller in areas where light and sound travel less far, such as near forests. Furthermore, fireworks should mainly be lit at central locations in built-up areas, as far away from birds as possible. It would be best for birds if we moved towards light shows without sound, such as drone shows or decorative fireworks without very loud bangs.”

3 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair（婴儿车）, she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.
The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma（哮喘）.
Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."
“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets（小装置）. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution？'So we did it."
Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."

4 . The world of underwater slumber is unlike what we see on the surface. For mammals (哺乳动物), a good night’s sleep sends an animal into a state of unconsciousness (无知觉) during hours of restorative sleeping that helps heal the body and solidify memories firmly in the mind. For fish, however, sleep isn’t such a well-defined process. Instead, many fish species have taken to spending short periods in a state of reduced activity or rest while keeping their eyes open to scan the water for potential threats. During these periods of reduced activity, a fish’s bodily functions slow down and its watchfulness drops.
The breadth of animals in the ocean that exhibit this type of reduced activity is wide-reaching. Among the hundreds of thousands of creatures in the sea, some merely ride along with the current, such as jellyfish. Others find rocky bedrooms for the night, while those such as stingrays bury themselves in the sand to rest. However, it must be really hard to get a good night’s sleep when you breathe air but live in water. This is something that the world’s underwater mammals have to deal with.
To prevent themselves from drowning (溺死) in their sleep, underwater mammals such as dolphins and manatees have developed the ability to “turn off” one side of their brain to rest, known as unihemispheric sleep. While one side is fast asleep, the other keeps all the animal’s vital functions running, such as breathing. Manatees, for example, love to sleep, spending up to 12 hours a day in a deep slumber. However, as air-breathing animals, manatees need to surface every 20 minutes or so for oxygen. To achieve this, the half of the brain that’s still awake sends the sleeping manatee to the surface to get some air.

5 . Throughout history, many species of animals have been threatened with extinction. When Europeans first arrived in North America, more than 60 million buffalo (水牛) lived on the continent. Yet hunting the buffalo was so popular during the 19th century that by 1900 the animal’s population had fallen to about 400 before the government stepped in to protect the species. In some countries today, the elephant faces a similar challenge, as illegal hunters kill the animals for the ivory in their tusks.
Yet not all animals with commercial value face this threat (威胁).The cow, for example, is a valuable source of food, but no one worries that the cow will soon be extinct. Why does the commercial value of ivory threaten the elephant. while the commercial value of beef protects the cow?
The reason is that elephants are a common resource, while cows are private goods. Elephants wander freely without any owners. The hunter has a strong motivation to kill as many elephants as he can find. Because illegal hunters are numerous, each has only a slight motivation to preserve the elephant population. By contrast, cattle live on farms that are privately owned. Each farmer makes great effort to maintain the cattle population on his farm because he harvests the benefit of these efforts.
Governments have tried to solve the elephant’s problem in two ways. Some countries, such as Kenya and Uganda, have made it illegal to kill elephants and sell their ivory. Yet these laws have been hard to put into effect, and elephant populations have continued to dwindle. By contrast, other countries, such as Malawi and Namibia, have made elephants private goods and allowed people to kill elephants, but only those on their own property.
With private ownership and the profit motive now on its side, the African elephant might someday be as safe from extinction as the cow. The ancient Greek philosopher Aristotle pointed out the problem with common resources: “What is common to many is taken least care of, for all men have greater regard for what is their own than for what they possess in common with others.”

8 . The rhino census (犀牛普查) is out, bearing good news for the greater one-horned rhinos! In September, 2022, the International Rhino Foundation (IRF) documented in a report that there is a baby boom in this population, representing an increase of 167 percent.
According to the report, there are a total of 4,014 greater one-horned rhinos living in India, Nepal, and Bhutan. Although this is positive news, their IUCN (International Union for Conservation of Nature) status still remains vulnerable.
In India alone, the home to 70 percent of the world’s greater one-horned rhinos, there was an increase of 274 rhinos since the last biannual census, according to the organization Rhino Review.
An important reason for this baby boom is the fact that Assam, India, has enlarged Kaziringo National Park, home to the world’s largest one-horned rhino population. The park went from 430 square kilometers to 1,040 square kilometers. This gives more breeding areas for the rhinos, and they are closed to visitors during breeding season.
India and Nepal are also protecting the rhinos by enforcing wildlife crime laws. To reduce rhino death by poaching (偷猎), the IRF donates vehicles and equipment, plus education including guard training and crime investigation.
The IRF data for other rhino species is not as promising, although the greater one-horned rhino numbers are encouraging for future conservation. According to the report, there is a decline in Sumatran rhinos, Africa’s white rhinos, while the Javan rhino population is stable and threatened by loss of habitat.
The State of the Rhino report offers hope for these other species. Given that the greater one-horned things were once close to extinction, with fewer than 100 living in the world, their recovery is incredible. This demonstrates that there are solutions when organizations and people work together. Let us hope that this successful rhino baby boom will affect other endangered wildlife species around the globe.

10 . Dogs may have earned the title of our best friends through their interactions with humans, but now researchers say these social skills could, be present shortly after birth rather than being learned.
To better understand the role of biology in dogs’ abilities to communicate with humans, the researchers studied 375 eight-week-old service dogs. They looked at how these dogs performed in a series of tasks designed to measure their communication skills. The puppies were still living with their littermates (同窝出生者) and had not been sent to live with a volunteer puppy raiser, making it unlikely that they had learned about his or her behavior.
In the first task, a person hid a treat beneath one of two overturned cups and pointed to it to see if the puppy could follow the gesture. Since dogs are good at using noses to find things a treat was also taped to the insides of, both cups. In the second task, puppies watched as the researchers placed a yellow, block next to the correct cup, instead of pointing to indicate where the puppy should look for the food.
The third task was designed to observe puppies’ tendency to look at human faces. The researchers spoke to the puppy in a voice people sometimes use when talking to a baby. They then measured how long the puppy fixed a stare on the human.
In the last task, researchers sealed a treat inside a closed container and presented it to the puppy. They then measured how often the puppy looked to the human for help in opening the container.
The study found that while many of the puppies were responsive to humans’ physical and verbal cues, very few looked to humans for help with the unsolvable task. Researchers said, “This suggests that while puppies may be born knowing how to respond to human-initiated communication, the ability to initiate communication on their own may come later.” The next step will be to see if specific genes that may contribute to dogs’ abilities to communicate with humans can be identified.
