The County Administrative Board (Länsstyrelsen) has given the green light for the release of Atlantic sturgeon into the Göta River so that it can recover in Swedish waters. Today, the fish is considered regionally extinct on Sweden's red list.

It was about a hundred years ago that the Atlantic sturgeon last swam in the Swedish water system of the Göta and Nordre rivers. The reason for its disappearance was that it was heavily fished, and it was also strongly affected by the homogenization of the watercourse and the expansion of hydroelectric power.

The "Return of the Sturgeon" (Störens återkomst) project is run by the Swedish Association for Sport Fishing and Fisheries Conservation (Sveriges sportfiske- och fiskevårdsförbund) with the aim of re-establishing the species, primarily in the Göta and Nordre Älv as the main area. This is also done in cooperation with the University of Gothenburg, the Swedish University of Agricultural Sciences and the Gothenburg Museum of Natural History.

There is also cooperation with Germany, where experts from the Leibniz Institute for Freshwater Ecology and Inland Fisheries in Berlin have already secured fry. The Germans are said to be experts in the ecology of the Atlantic sturgeon and also have long experience in reintroducing the species.

The County Administrative Board (Länsstyrelsen) in Västra Götaland has now given the go-ahead for the release of the sturgeon, and the next step will be to transport about ten young fish for release. The fish will be tagged and monitored for some time to see how the release works, and more fish will be shipped from Germany to Sweden in May.

"A unique event"

– This is a unique event. That Sweden actively regains a regionally extinct species, that is very unusual! It's so exciting, and I really look forward to the day when we can look at the river and think 'there below swims an Atlantic sturgeon as well', project manager and biologist Linnéa Jägrud told the sport fishing magazine Sportfiskarna.

The sturgeon is said to have played an important role in Scandinavian history, and archaeological finds have been made that are believed to date back to the 15th century. Anglers say that restoring the species is partly about preserving biodiversity, but it is also a way of restoring the lost identity of the river. It could also increase the potential for sustainable fishing in the future.

– At a time of setbacks for nature, environmental difficulties and unprecedented species extinction, the reintroduction of an extinct species would send an important and inspiring signal to conservationists across Europe and the West, says Jägrud.

“The Great Moose Migration” reduces stress and anxiety

Swedish public broadcaster SVT's nature program helps millions of viewers relax and feel connected to nature – despite the experience being digital, shows a study from SLU.

The Great Moose Migration is a program that annually livestreams the spring migration of moose in Kullberg in Ångermanland, northern Sweden. For 20 days, viewers follow the moose as they travel through forests and swim across the Ångerman River. The program attracts millions of Swedes each year, as well as viewers in other countries.

Now researchers at SLU (Swedish University of Agricultural Sciences) have examined how viewers are affected by the moose program. Through surveys distributed via social media and the program's live chat, over 2,000 people have described their experiences. The results, published in the journal People and Nature, show that the program creates a strong sense of calm and connection to nature.

— Viewers describe how the sound of wind, birds, and rain gives a feeling of presence, and how the slow rhythm of the broadcast helps them unwind. Many experience that the program reminds them of childhood memories, previous nature experiences, or places they have a personal connection to, says researcher Minh-Xuan Truong in a press release.

Relieves anxiety

The program is a typical example of so-called "slow TV", where viewers simply follow the moose at nature's pace without any narrator, quick cuts, or dramatic music.

What makes the experience so realistic is primarily the natural sounds. The river's murmur, birdsong, and the whisper of wind create a feeling of actually being at the location. Some viewers even reported that they could smell the rain or pine forest.

The fact that the program is unedited is also appreciated. Sometimes animals are visible, sometimes not – just like when hiking in the forest in real life.

The study shows that the silence, slow images, and nature's beauty function as a break from everyday stress. Several participants in the survey described how the program relieves headaches and anxiety, while others emphasized the calming effect of seeing animals in their natural environment.

Does not replace real nature experiences

Viewers generally report feeling a strong connection to nature. The feeling was particularly pronounced among people who frequently spend time outdoors and are environmentally engaged. The connection to nature also tended to increase with age. The live chat during the program is also appreciated, as many experience that it creates a sense of community.

The researchers emphasize that digital nature experiences can never replace being outside yourself, but that they can function as an important complement.

— Digital outdoor life seems to be able to promote recovery and connection to nature in a similar way to experiences in actual nature. It can of course never replace real nature experiences, but it can be an important complement, especially for people who have difficulty getting outside, said Truong.

China’s emissions may have peaked – massive investment in renewables

The modern China

China accounts for over 30 percent of the world's greenhouse gas emissions, but is simultaneously investing more than any other country in renewable energy and electric vehicles. New figures suggest that Chinese emissions may have peaked earlier than expected.

China emits an estimated 15.6 gigatons of carbon dioxide equivalents (carbon dioxide and other greenhouse gases) annually, making the country the world's single largest emitter. But behind the figures, a comprehensive transformation is underway, reports AFP.

Chinese electricity production is still dominated by coal, which accounts for nearly 60 percent of generated power. But massive installations of renewable energy are rapidly changing the picture. China now has 1,482 gigawatts of installed solar and wind power capacity and aims to increase its capacity sixfold from 2020 levels to 3,600 gigawatts by 2035.

According to analysts' assessments, the goal is realistic – in fact, so realistic that the country may reach it earlier than planned. During 2024, China added significantly more than the 200 gigawatts per year that would be required to meet the target.

Electric vehicles taking over the market

In the automotive market, the transition has been even faster. Nearly half of all new cars sold in China during 2024 were either electric or plug-in hybrids. The country accounts for over 70 percent of global electric vehicle production and has, according to the International Energy Agency (IEA), become the world leader in the field.

President Xi Jinping has stated that vehicles with "new energy" should become mainstream in the Chinese market – a goal that has essentially already been achieved.

Emissions may have peaked

In September, China presented concrete numerical targets for emission reductions for the first time: a reduction of 7–10 percent by 2035.

Some observers believe that Chinese emissions have already reached their highest level, or are close to doing so, thanks to the rapid expansion of renewable energy and nuclear power. Beijing has previously committed to reaching peak emissions by 2030 at the latest and to being "carbon neutral" by 2060.

In China, debate about the downsides of wind power is not common, and large amounts of wind power have been installed in desert areas and offshore in recent years.

Income level found to influence garden biodiversity

Biodiversity

Researchers see gardens as a potential tool for preserving biodiversity as global diversity declines.

Households with lower incomes tend to have more biodiversity in their gardens, according to a study from North Carolina State University in the United States. People with higher incomes prefer neatly mowed lawns instead.

In the study, published in HortScience, researchers examined attitudes toward biodiversity in the United States. They surveyed over 2,000 people and looked at whether they had any innate appreciation for biodiversity, something called biophilia.

The results showed that far from all people had an innate appreciation for biodiversity, and it varied greatly between individuals. However, it was not uncommon for it to develop early in life.

Biodiversity is declining globally and climate goals are often not met. Therefore, researchers have begun to see gardens as a tool for preserving plant and animal life. But to succeed, they must first understand who is willing to let their gardens grow wilder.

— While a single person’s garden isn’t going to do much individually, as a collective they could be a big part of conserving biodiversity. The question then becomes; how do you get those people to change their gardens in that way? says Vanessa Woods, doctoral student at NC University, in a press release. To do that, you must first identify the people who are receptive to these more natural gardens with greater biodiversity.

Income plays a role

The most important factor for biophilia was income level, the researchers conclude. The higher the income, the less inclined people were to have more biodiversity in their garden, preferring neatly mowed lawns.

The lower the income level, the more positively disposed people were to a more wild-grown garden. Households with an income below $25,000 per year showed the greatest interest in biodiversity. Additionally, people who lived more environmentally friendly lifestyles were also more open to a garden that promotes biodiversity.

Melinda Knuth, lead researcher and associate professor at North Carolina State University, believes it is important to identify those who are attracted to biodiversity in order to bridge the gap between intention and conservation actions.

— To do that, you first need to identify the people who will be receptive to those messier, more biodiverse types of gardens, she says.

Leopard seals sing lullabies

Published October 24, 2025 – By Editorial staff
Male leopard seals sing up to 13 hours per day during mating season to attract females
2 minute read

The mating calls, or songs, of leopard seals resemble human nursery rhymes and lullabies, new analyses show. Among other things, the song is reminiscent of "Baa, Baa, Black Sheep".

Leopard seals live in Antarctica where they mostly spend their time hunting penguins or relaxing on the floating sea ice. They can grow nearly four meters long and weigh between 300 and 500 kilograms. Males also have another repetitive occupation – and that is to find a female to mate with. To do this, the males "sing" when they are underwater. They do this every day from late October to early January.

Males can sing for up to 13 hours per day. Females also sing, but only for a few days a year when they are in heat.

— It’s big business for them. They’re like the songbirds of the Southern Ocean. During the breeding season, if you drop a hydrophone into the water anywhere in the region, you’ll hear them singing, says Professor Tracey Rogers, from the University of New South Wales (UNSW), in a press release.

Now researchers have analyzed recordings of the male seals' songs to better understand their structure and patterns. There they discovered that the structure of leopard seal songs resembles nursery rhymes or lullabies.

"Baa, baa, black sheep"

In total, songs from 26 different males were studied and it was found that the sounds were very similar in pitch and length, but that the order and pattern in which the sounds were emitted varied considerably between individuals.

"We think this is a deliberate strategy. While leopard seals are solitary animals, the males need their call to carry clearly across vast stretches of icy ocean, to woo a mate", the researchers write in Science Direct.

The researchers compared the song with several different styles of human music and discovered that it consisted of five key notes. What also stood out were the similarities between the predictability of nursery rhymes and leopard seal calls. Nursery rhymes are characterized by being simple, repetitive and easy to remember, something that the seals' songs also were.

Among other things, they found similarities with the well-known rhymes "Twinkle, Twinkle, Little Star", "Baa, Baa, Black Sheep" and the classic "Rock-a-bye Baby". The simple melodies likely make it possible for the male leopard seal to continue singing his unique mating call for several days, which is important to avoid changes in pitch or frequency as this could create misunderstandings among other leopard seals.

— It’s the order and pattern that matters. They’ve stylised it to an almost boring degree, which we think is a deliberate strategy, so their call carries a long distance across the ice, says Professor Tracey Rogers.
