3 . More than 50 percent of the largest lakes in the world are losing water, storing less water than they did three decades ago, according to a new assessment published today in Science. The key causes are not surprising: The warming climate and unsustainable human consumption.
Lead author Fangfang Yao, a climate fellow at University of Virginia, and his team created a technique to measure changes in water levels of nearly 2,000 of the world’s biggest lakes and reservoirs (水库), which represent 95 percent of the total lake water storage on Earth.
They used 250,000 lake-area pictures taken by satellites between 1992 and 2020 to survey the area of 1,972 of Earth’s biggest lakes. They collected water levels from nine satellite altimeters (测高计) and used long-term water levels to reduce any uncertainty. For lakes without a long-term level record, they used recent water measurements made by newer instruments on satellites. Combining recent level measurements with longer-term area measurements allowed scientists to reconstruct the volume of lakes dating back decades.
The result was staggering: 53 percent of lakes globally experienced a decline in water storage. The authors compare this loss with the size of 17 Lake Meads, the largest reservoir in the United States.
To explain the trends in natural lakes, the team used recent advancements in water use and climate modeling. “Climate change and human water consumption were mainly responsible for the global net decline in natural lake volume and water losses in about 100 large lakes,” Yao said. “And many of the human and climate change footprints on lake water losses were previously unknown, such as the dryness of Lake Good-e-Zareh in Afghanistan.”
And their research offers an understanding into possible solutions. Yao said, “If human consumption is a large cause of lake water storage decline, then we can adapt and explore new policies to reduce large-scale (大范围) declines.” This happened in one of the lakes the team studied, Lake Sevan in Armenia. Lake Sevan has seen an increase in water storage, in the last 20 years, which the authors linked to the enforcement (实施) of conservation laws on water withdrawal since the early 2000s.

4 . On April 10, the University of Utah became officially Bee Campus certificated. This process was started by senior Zoē Bross in her second year on campus. Bee Campus USA hopes to protect the native pollinators (传粉者) on college campuses by increasing the number of native plants, providing nest sites, reducing the use of pesticides, and offering educational opportunities that help with pollinator conservation.
After first hearing her school wasn’t certificated a Bee Campus and finding becoming Bee Campus certificated would give the University more point s on the Advancement of Sustainability in Higher Education Sustainability Tracking, Assessment & Rating System (STARS) program, which decides ratings to campuses according to their sustainable efforts, Bross wanted to help.
There are many requirements to become Bee Campus certificated. The first major step for Bross was to create a standing Bee Campus committee with a mix of students and staff. Bross tried to reach out to professors and people specializing in this field. After many efforts, the program was finally passed through and a garden for it was created.
Over 100 people showed up to help plant in the garden. After the planting was done, Grounds, responsible for planting the pollinator gardens, set up their hydroseeder (水力播种机) and let attendees take turns spraying the hill, with a mixture of water and wildflower seeds, making the area more pollinator-friendly. Rocky, the school robot, even made an appearance, taking turns spraying.
Certificated by Bee Campus USA, Bee Campuses are expected to continue maintaining or improving pollinator habitats on campuses, as well as maintaining an educational online presence. “I see the campus continuing to be very interested,” Bross stated.
Future plans for the campus include more pollinator gardens, native wildflowers, and even bee sculptures to provide new habitats. As for Bross? She pictures herself somewhere warm and sunny in the near future, working in environmental communications and doing something for the change she wants to see in the world.

6 . In Canada, you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends.
Before they keep them in their houses, they take them to animal hospitals to give them injections (注射) so that they won’t carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal, you would be punished. If an animal happened to get run over by a car, people would be very sad.
People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life. Then the old will feel lonely. But pets can solve this problem. They can be good friends and never leave them alone.

7 . Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change.
Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer conditions expedite the sharks’ growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.
The scientists studied 27 sharks. Some were raised in average summer water temperatures, about27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.
Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.
One study this year found that worldwide numbers of oceanic sharks and rays dropped more than70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten sharks.
Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She is the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild.
She added that if the sharks are born smaller than usual, they are probably going to have to start looking for food sooner, and they’re going to have less time to adjust to their surroundings.
The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.

8 . While they can’t pick out precise numbers, animals can comprehend that more is, well, more. From birds to bees and wolves to frogs, animals use numbers to hunt, find a mate, return to their home, and more. Researchers believe that this ability, known as numerical competence, plays an important role in how animals make these decisions. Andreas Nieder, a biologist at the University of Tübingen, explores the current literature on how different animals comprehend numbers.
Honeybees, for instance, can remember the number of landmarks they pass when searching for food in order to find their way back home. This ability can also be seen in animals choosing a larger amount of food over a smaller amount or in animals forming hunting groups. Wolves are more likely to hunt successfully if they have the right number of wolves in their pack for their prey (猎物) with prey like elk (驼鹿), only around six to eight wolves are needed, while hunting wild pigs requires a pack of nine to thirteen. Their prey also uses this concept to protect themselves—elk tend to live in small groups, which rarely have encounters with wolves, or gather in large groups to reduce the chance of any individual becoming prey. “They are assessing the number of individuals in their groups for their everyday life situations,” Nieder says.
Furthermore, numerical competence also plays a role in attracting a mate. For example, male frogs sing “advertisement” calls to attract females. The females, listening to their complicated calls, choose the males that sing the most “chucks” in their calls.
Now researchers do have some sense of the rules that govern numerical competence in animals. For example, they count approximately (大概) rather than specifically and two numbers need to be more different for them to tell them apart as those numbers get bigger. However, Nieder argues that more research needs to be done. “I hope I can encourage behavioral ecologists to specifically explore numerical competence in the wild, and, in doing so, also open new research fields,” he says.

9 . In an awe-inspiring incident, a young killer whale recently demonstrated remarkable intelligence by seeking assistance from a group of humans to save its trapped mother, which challenged our conventional understanding of wild predators (食肉动物).
The online viral video, shared by Alvin Foo, began with a young killer whale emitting distressing cries towards a group of people on a boat. Recognizing the urgency of the situation, the concerned individuals promptly responded by contacting a rescue team. The young whale’s desperate request for help touched more people’s hearts and set a truly extraordinary chain of events in motion.
As the rescue team arrived, they were amazed to witness the young killer whale’s playful interaction with the humans. The whale appeared elated, seemingly understanding that assistance had finally arrived. This interaction between the mother killer whale and rescuers underlined the potential for mutual understanding beyond the boundary of traditional predator-prey relationships.
The young whale took on the role of a guide, leading the rescue team to its mother trapped in a fishing net. It navigated the water with purpose, as if fully aware that the humans possessed the means to save its mother. This display of intelligence left the rescuers in awe, highlighting the complex cognitive abilities of these magnificent marine creatures. With its guidance, the rescue team swiftly initiated the liberation process, carefully cutting the net to free the trapped whale. Astonishingly, they seemed to understand that the humans were there to help and did as asked.
The instant the mother whale was finally freed, an eruption of joyous cries filled the air. The emotional outpouring conveyed the immense gratitude of both the mother whale and the young whale to the humans who had intervened. As the rescue team made their way back to shore, the two whales swam alongside them. This heart-warming sight emphasized the lasting impact of the rescue. The bond formed through this extraordinary rescue operation was well obvious, proving that the profound connections can be established between various species. The journey back to safety symbolized the victory of compassion over adversity.

10 . New research by scientists at the University of Bristol explains how a “stop－start” pattern of evolution,governed by environmental change,could explain why crocodiles (鳄鱼) have changed so little since the age of the dinosaurs.
Crocodiles today look very similar to ones from 200 million years ago. There are also very few species alive today—just 25. Other animals such as lizards and birds have achieved a diversity of many thousands of species in the same amount of time. Prehistory also saw types of crocodile we don’t see today,including giants as big as dinosaurs,plant－eaters,fast runners and snakelike forms that lived in the sea.
The rate of their evolution is generally slow,but occasionally they evolve more apace because the environment has changed. In particular,this new research suggests that their evolution speeds up when the climate is warmer,and that their body size increases.
Lead author Dr. Max Stockdale said,“Our analysis used a machine learning algorithm (算法) to estimate rates of evolution. Evolutionary rate is the amount of change that has taken place over a given amount of time,which we can work out by comparing measurements from fossils and taking into account how old they are. For our study we measured body size,which is important because it interacts with how fast animals grow,how much food they need,how big their populations are and how likely they are to die out.”
The findings show that the limited diversity of crocodiles and their apparent lack of evolution result from a slow evolutionary rate. It seems the crocodiles arrived with an already efficient and versatile (多功能的) body plan that doesn’t require changes. This versatility could be one explanation why crocodiles survived the meteor (流星) impact at the end of the Cretaceous period,in which the dinosaurs died out. Crocodiles generally develop better in warm conditions because they cannot control their body temperature and require warmth from the environment.
