Bean tree plan to protect Amazon

A new project aims to use Inga trees to keep land fertile for the long term, reducing pressure on smallholders to abandon their land. The plan could help maintain tree cover in the Amazonian Arc of Deforestation by supporting sustainable agriculture and providing a premium income for milk produced from grazing cattle.

Jackdaws learn from each other about 'dangerous' humans

Researchers at the University of Exeter found that jackdaws can learn to identify dangerous people by hearing a warning call, and this knowledge helps them avoid humans who pose a threat. The birds that heard the warning call returned to their nests more quickly when seeing the human again, indicating they had learned to recognize danger.

Diving birds follow each other when fishing

European shags follow social cues by watching fellow birds to determine the best time and place to dive. This behaviour may help them save energy and find fish more efficiently. The study sheds light on the importance of understanding seabird species' adaptability in response to environmental pressures.

Staring at seagulls could save your chips

Researchers found that herring gulls take 21 seconds longer to approach food when a human is watching, suggesting that just observing the birds can reduce food-snatching. The study highlights the importance of modifying individual behavior to manage gull-nuisance issues in urban areas.

Study reveals how bacteria beat immune systems

A new study by University of Exeter researchers shows that pathogens can evolve to become more virulent without increasing their rate of replication. This suggests that manipulating host immune systems may play a role in generating symptoms necessary for transmission.

'Intensive' beekeeping not to blame for common bee diseases

A study by researchers from the University of Exeter and Berkeley found that crowding honeybees together does not greatly increase disease prevalence. However, intensive beekeeping could accelerate the spread of new diseases. Beekeepers don't need to worry about the number of bees they keep together as long as there is enough food.

Healthy lifestyle may offset genetic risk of dementia

A new study found that living a healthy lifestyle can significantly reduce the risk of dementia for individuals with a high genetic risk. The research, published in JAMA, analyzed data from over 196,000 adults and discovered that adhering to a healthy lifestyle, regardless of genetic risk, was associated with a reduced risk of dementia.

Project to examine 'price of birdsong'

A new project at the University of Exeter aims to discover how economics can help protect the environment by placing an economic value on biodiversity. The project will develop trading platforms to advance price measurements of biodiversity and provide individuals and businesses with access to conservation solutions in various countries.

'Gentle recovery' of Brazil's leatherback turtles

Researchers found a significant increase in the number of leatherback nests in Espírito Santo, Brazil, from 25.6 to 89.8 between 1988 and 2017. The gentle recovery is attributed to local conservation efforts, but the population still faces threats from climate change, pollution, and coastal development.

Climate change benefits for giant petrels

A new study finds that climate change will benefit giant petrels with warmer weather and improved foraging conditions, allowing them to dominate access to carrion on land and travel less at sea. However, females may be harmed by increased longline fishing, which could impair their survival.

Honeybee mite raises bumblebee virus risk

A study by the University of Exeter found that Varroa destructor mites indirectly increase infection rates among wild bumblebees by spreading deformed wing virus (DWV) through honeybee colonies. This highlights the need for beekeepers to treat their affected colonies.

Worm study sparks hope for slowing muscle decline

A recent study published in the FASEB Journal has found that inhibiting various stages of mitochondrial dysfunction can suppress muscle atrophy. Researchers used Caenorhabditis elegans worms to model human muscle diseases and showed that experimental drugs could prevent muscle decline caused by dysfunctional mitochondria.

Fishing among worst jobs for health

Fishing workers in England and Wales experience poor general health, with 2.8% reporting 'bad' or 'very bad' health and 10.3% limited by long-term illness. The industry is facing social, environmental, and political change, highlighting the need for targeted interventions.

Some songbird nests are especially vulnerable to magpie predation

A new study found that magpies are the most common predators of songbird nests, accounting for 70% of visits. Nests within magpie breeding territories were also more likely to be predated, especially in late season when magpies have young. The research highlights the need to identify and remove problem individuals to improve management...
