Whales are an important part of the ocean. They maintain the ocean ecosystem by providing important nutrients for phytoplankton (浮游植物), microscopic organism (微生物) in the ocean, to grow as food for fish and other animals. Phytoplankton also carry out photosynthesis (光合作用) to keep carbon dioxide level low in the atmosphere to keep the Earth cool. So, without whales, the oceans wouldn’t be healthy.
Currently, North Atlantic right whales are critically endangered. Scientists from University of South Carolina and Cornell University imagined that it is the warmer ocean waters that force whales to go to new places that don’t have rules, such as speed limits for ships, shorter fishing seasons, etc., to protect whales.
To see if climate changes can explain the loss of whales, scientists analyzed the water temperature near the Gulf of Maine, the feeding place of the whales. The temperature is affected by the position of Gulf Stream which brings warm water from the south.
They also looked at population data for the whales and their food, which is primarily small shrimps and crabs called copepods. They estimated how the whale population changed based on the number of whale sightings, whale birth and their bodies. Finally, they analyzed how the change in the water temperature related to the change in the whale population.
The result showed that since 2010, the Gulf Stream has been farther north than ever before, bringing warmer waters to the region. The population data shows a significant decrease in copepods population beginning in 2010. This means there has been less food available for the whales.
The best explanation is that global warming is causing the northward shift of the Gulf Stream, which is consistent with climate change, and making the waters near the Gulf of Maine warmer. However, copepods prefer cold water. Warmer water wakes them too early, they miss the nutritious spring phytoplankton bloom they need to grow. Besides, when the Gulf Stream is farther north, less copepods are brought into the Gulf of Maine.
With food levels too low, fewer whales are born, and fewer survive. To find enough food, some whales swim north to the Gulf of St. Lawrence. Therefore, there were more whale sightings there. It also explains why there were more whale deaths in the area in 2017 and 2019. By looking at the carcasses, scientists know that ships hit the whales, or they got trapped in fishing gear. So, climate change both makes the whales’ food shorter and causes them to move to new places, making it harder to protect them.
Global warming doesn’t only change the weather; it changes the ocean. To protect ocean species and keep our oceans healthy, governments need to adjust how they manage the ocean.

For their study, biologist Corson Miller and his team exposés eleven selected dogs to digital images of women that were either angry or happy．Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry．
Interestingly, the dogs were not provided with the entire face．Some dogs were show Ti only upper halves while the others observed lower halves．That's because the scientists believe humans show their eruptions on their equities face．
After some training on how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions．
They also found those being trained to read angry expressions took a longer time to learn．They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly．However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear．In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed．
The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly．Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner．

【推荐2】Climate change is changing the migration routes of animals worldwide. Take the mule deer for example. Every spring in Wyoming, green-up first appears at lower altitudes before progressing up the mountainside. Migrating mule deer follow and seek food on this green wave. But as a changing climate leads to more frequent and more severe droughts, the greenery is not as abundant as it used to be.
Ellen Aikens, a researcher from the University of Wyoming, tracked mule deer as they surfed the green wave. In comparison to wet years, the green-up lasted across the landscape for about half as long in drought years and was also fragmented. Although the deer were able to keep up with the faster green wave, the nutritional value was lower, leaving the animals less prepared for the challenges of the year ahead.
Meanwhile in Europe, the population of Bewick’s swans that spend the winter in the Netherlands is declining. But when researchers looked at the data more closely, they found an increase in the wintering population of swans in Germany. It turns out that since the 1970s, the swans’ wintering habitat has shifted an average of 13 kilometers to the east each year.
“The swans like to spend time where it’s 5℃. And the temperature line has shifted in the same rate as the swans shifted eastward,” said Rascha Nuijten, an ecologist at the Netherlands Institute of Ecology.
These findings are important to our understanding of the conservation of migrant animals. When it comes to protecting a certain species, it’s not just about the current situation. Nature is dynamic. And the species that is present now might not be present in 10 years, not because we didn’t protect it but because maybe it is dynamic in its way. We need to include the dynamics of nature into our legislation and management.

【推荐3】What does your dog do if you lie down on the floor and put your arms or legs out straight to exercise? Does your dog come to your rescue in the same way as if you fell down, or realize you mean to do that? Researchers in Germany carried out a series of experiments to see whether dogs understand if humans do things on purpose.
For their study, they had 51 dog owners drop off their pets to the laboratory. First, the dogs learned that a human experimenter would feed them treats through a gap in a glass partition (隔断). And the researchers designed two situations, which were known as “unwillingness vs. inability”. In the “unwillingness” situation, the experimenter held the food in front of the dogs but didn’t give it to them on purpose, often teasing (戏弄) them before pulling it away. For the “inability” situation, they had two conditions, one where the person seemed clumsy (笨拙的) and he appeared as if he were trying to give the treat to the dogs, but it fell down. In the other, the gap was enveloped and the pet couldn’t get the treat.
In all of these experiments, the experimenter left the treat on the floor in front of the dogs, and the dogs were easily able to get to the treat. How quickly they got back the food depended on the specific situation. The researchers predicted correctly that the dogs would wait longer to go to get the treat if they thought the experimenter didn’t want them to have it, while they went to get it quickly when the treat was meant for them. “They probably understood that -This guy is not very skilled but he wants to give the food to me.” Bräuer suggests.
Bräuer says that there could be other factors that led to the dogs’ such performance in the experiments. Although she thinks the findings are important, Bräuer says she is looking forward to what other scientists around the world will say.

【推荐1】Australia recently declared the koala an endangered species in Queensland, the Australian Capital Territory, and New South Wales (NSW) because of its obvious population decline. In the state of NSW, koala conservation has become a key topic of discussion in the lead-up to the 25 March state election. However, the debate has focused on the expansion of protected areas and ignored the importance of koala conservation on private lands.
The major cause of the koala’s decline—in addition to climate change, wildfires, disease, and encounters with vehicles and dogs—is the loss and degradation(退化)of suitable habitat. In response, the NSW Government has expanded publicly protected areas in the state. Over the past 20 years—about three koala generations—NSW has officially confirmed an additional 1.5 million hectares(公顷)of protected land, some of which is high-quality koala habitat.
However, across Queensland, the Australian Capital Territory and NSW, 77% of the koala’s range is located on land that is owned or rented by private citizens or businesses, where degradation continues. Between 2003 and 2020, agriculture, forestry and infrastructure(基础设施)development have led to the act of cutting down or burning the trees within 760,500 hectare in NSW, including in regions such as the Cumberland Plain and Liverpool Plains, where koalas are known to live. Such development has reduced the gains made through new protected areas.
The current NSW Koala Strategy adopts a free approach without any restrictions, which leaves private landowners, renters and industry have the power to decide what should be done in much of koala habitat conservation.
An effective koala conservation strategy must include conservation measures in private protected areas, such as payments for ecosystem services, in addition to publicly protected areas. In other words, post-election agendas must strengthen protection of koala habitats on private lands.

【推荐2】Do you know what to do if you see a bird with a broken wing in your backyard, or a hurt raccoon (浣熊) by the side of the road? Use your phone!
It’s never a good idea to touch a wild animal or to try to help one without professional guidance. The animal might be dangerous to you，and you could cause further injury without meaning to.
That’s why the wildliferescue organization Animal Watch has created a new mobile app. The app helps users find the right solutions for animals that need urgent (紧急的) care.
Animal Help Now uses your phone’s GPS to find where the animal is located. Then the app asks questions about the animal: Is it wild or raised by humans? Is it a pet or a farm animal? Could the animal put humans in danger?
Based on the location, the time of day, the type of animal, and the injury, Animal Help Now will suggest a care provider that’s right for your situation. For wild animals, the app might suggest a nearby rescue facility that specializes in wounded wildlife. Or it might point you to registered care takers who nurse animals that have been hurt in the wild back to health. For pets or farm animals, the app lists the nearest veterinarians (兽医) who care for the type of animal that has been injured.
“The app is designed to work even when you don’t have cell or Internet access,”Animal Watch director Dave Crawford tells National Public Radio.
“So whether you’re driving through a remote area on the eastern Colorado plains, hiking a trail in Rocky Mountain National Park, or simply passing through a dead zone on your way to work，you’ll still be able to immediately find the help you need.” For now, Animal Help Now works only in Colorado, where Animal Watch is based. But the organization hopes to include information for users across the country.

Humans share Earth with many different kinds of wildlife. However, many of our animal and plant friends may not be around for much longer. According to a recent report on biodiversity, 1 million of Earth's 8 million species (物种) are in danger of extinction(灭绝).
Humans are mainly responsible for the danger. According to the report, the world's population has doubled in the last 50 years. Humans have used over a third of the world's land and 75% of fresh water to grow crops and keep animals. As a result, there are fewer habitats and fewer natural resources available.
Because of human activities, the global rate of species extinction over the past 50 years has been higher than it has averaged over the past 10 million years. The species extinction could have serious effects on ecosystems. We fail to notice when losing one species, then another, then… These are the types of changes we're observing where entire ecosystems break down. These developments lead scientists to believe that there could be a sixth mass extinction, the first to be caused by humans. No one want to experience one mass extinction like the one where the dinosaurs that died out last time.
Aimed at solving the problem, many countries have taken action. For example, China has banned the use of rhino horn and tiger bones, and the ivory trade, reported China Daily. According to Huffpost, there are things that we can do personally to save species. For example, don't buy products made from illegal ( 非法的)wildlife parts and reduce water waste. “Each individual action has an effect and every person can make a difference - through a mass we can turn the tide,” said Claudia Sobrevila, from Global Wildlife Program, according to official website of the WorldBank.

【推荐1】Masks that helped save lives are proving a deadly danger to wildlife, with birds and sea creatures trapped in the shocking number of thrown-away facial coverings. Single-use masks have been found around pavements, waterways and beaches worldwide. Worn once, the thin protective materials can take hundreds of years to decompose. “Face masks aren’t going away any time soon — but when we throw them away, these items can harm the environment and the animals,” Ashley Fruno of animal rights group PETA said.
In Britain, a gull was rescued by the RSPCA after its legs became tangled in the straps of a mask for up to a week. The animal welfare charity took it to a wildlife hospital for treatment before its release.
The biggest effect may be in the water. More than 1.5 billion masks made their way into the world’s oceans last year, accounting for around 6,200 extra tonnes of ocean plastic pollution, according to environmental group Oceans Asia.
Conservationists in Brazil found one mask inside the stomach of a penguin after its body was washed up on a beach, while a dead puffer fish was discovered caught inside another off the coast of Miami. French campaigners found a dead crab trapped in a mask near the Mediterranean.
Masks and gloves are “particularly problematic” for sea creatures, says George Leonard, chief scientist from NGO Ocean Conservancy. “When those plastics break down in the environment, they then enter the food chain and impact the entire ecosystems,” he added.
There has been a shift towards greater use of reusable cloth masks as the pandemic has worn on, but many are still using the lighter single-use varieties. Campaigners have urged people to bin them properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

【推荐2】Schoolbooks typically present explorers as intrepid individuals who, for example, sail wooden ships to new lands or climb Mt. Qomolangma alone. But today most explorers who are making fundamental discoveries are scientists. And whether the frontiers are tiny, like the human genome, or massive, like our deepest oceans, we still have much left to learn about planet Earth.
Exploration is science in its most basic form — asking questions of the natural world and, we hope, using the answers for the betterment of everything on Earth.
Exploration has great value. It inspires us, widens our knowledge and gives us hope for a better future. And the practical payoffs can even be lifesaving. Scientists who spent decades exploring what was in the atmosphere found that over time the concentration of carbon dioxide was rising. Without that discovery, we humans would now be living like the proverbial frog in a pot of gradually heating water, unsure why the environment around us is changing, and slowly boiling to death.
The human drive to overcome challenges is an essential aspect of the human drive to explore, which, in most cases, spurs innovation. Early human submersibles that reached the bottom of the deepest ocean trenches (海沟) made the trip just once, stressed by the enormous pressures there. But eventually a more stress-resistant deep–submergence vehicle, the Limiting Factor, allowed investor and undersea explorer Victor Vescovo to reach trench bottoms numerous times. Now there are roughly 4,000 autonomous Argo floats across the world’s oceans that dive down to 2,000 feet and resurface every 10 days. The Argo group will also deploy (部署) dozens of sensors every year that will gather biological and chemical data, leading to new observations about marine life.
Ocean research groups also have made it a priority to openly share their discoveries and data with the public and to inspire the next generation of young scientists. Anyone can go along for the ride — we can all be explorers. Maybe one day you’ll explore the Great Barrier Reef, the desert, or a rain-forest canopy (树冠).
Captain James T. Kirk began each episode of the original Star Trek television series by saying, “Space, the final frontier (前沿).” Not necessarily. We still have plenty to discover right here on Earth, and we eagerly await surprises from the newest worlds we find.

【推荐1】Warming seas across the globe are endangering coral reefs, a key ecosystem that supports marine life to live and thrive. As a possible way to save them from extinction, scientists have recently frozen and revived groups of adult corals for the first time, according to a recent study.
Freezing biological materials, or “cryopreserving” them, refers to keeping them in a deep freeze for long periods without affecting the cells viability (活性), according to the Science Times website.
This method usually cools them to very low temperatures, commonly to-196℃. Since cells would normally die at such a low temperature due to the formation of ice inside, scientists need to monitor the freezing rate and choose the freezing medium carefully.
Researchers in the US experimented with freezing pea-sized pieces of a common coral in Hawaii. After removing the microbes on the corals, they sealed the corals in metal containers filled with a chemical solution that partially dehydrated (脱水) them and helped control ice growth.
When the corals reached a temperature of around -200 ℃, the remaining water in the corals solidified into a glassy form. The corals were still alive, with their life-driving functions becoming extremely slow. After being cryopreserved for a few minutes, the researchers pulled the corals out and placed them in warm water. In two minutes, they started consuming oxygen — a sign of them staying alive.
Previously, researchers had already successfully cryopreserved coral larvae (幼虫), according to a study in 2018. However, the larvae can only be collected when corals spawn (产卵), which happens just a few nights each year. “That’s putting a lot of eggs in one basket,” US marine scientist Liza Roger told Science News.
This breakthrough offers more hope to the worlds corals, said Roger. However, there’s more work to be done. A few days after thawing (解冻), the corals became “stressed out” from the process and were killed by the bacteria they normally live in harmony with. The researchers are working on using antibiotics to help them survive for a longer period of time.

【推荐2】Andrew runs a car repair workshop in a village in London, where swallows have made their nests on the crossbeams beneath its roof. All day long, they fly in and out, bringing back insects for their hungry chicks, seemingly unconscious of the constant noise and the comings and goings of customers. However, this spring the swallows didn’t arrive back at his workshop until 10 April — the latest they have returned in nearly 40 years. Actually, the average return date has been 8 April, but this year I didn’t see one over my garden in Scottish Highlands until the 25th. Numbers are down, too. While the tide appears to have turned up from last weekend onwards, other familiar species, like house martin (毛脚燕), needle-tailed swift, etc have been very few and far between.
There are two reasons for their late arrival. Unlike many other migrating (迁徙) birds, which fatten themselves up before they depart, these species feed as they travel, replenishing (补充) lost energy by catching flying insects. For that reason, they are especially vulnerable to bad weather. And the weather in southern Europe this spring has been very unpredictable.
The second reason is that, here in Britain these years, although the weather has been mainly dry, there have been persistent easterly and northeasterly winds, which may have also slowed down the birds’ progress as they headed north.
How might this end up affecting these global travellers over the long term? Migrating birds usually live for only one or two years, so they need to get down to raising a family as soon as they return. Swallows, which usually start nesting in early April, may only be able to raise a single hatch this year, rather than two as they do in most years.
I have seen swallows all over the world and discovered just how important they are as a sign of spring: not just in Britain but all the way across the northern hemisphere. Yet I am concerned that rapid changes in the world’s climate pose a real threat to their chances of breeding successfully and their long-term future, even a week or two delays.
Fortunately, warm weather and clear skies have finally come to southern Europe, and the migration floodgates have opened. Earlier last week, down on the Somerset coast, I saw a steady passage of swallows, together with a few house martins, all heading steadily northwards. With warm sunshine and enough rain to produce quantities of insects, the swallows might be able to compensate for their lost time.
