New international research, led by New Zealanders, has found that fruit-eating birds living in stressful environments will up their calorie intake by eating the largest possible fruits that can easily fit in their beaks. The team looked at 97 bird species and the more than 800 plants from around the world they eat. They found birds will often eat fruits that match their beak size when they’re near their limits of where they live, where conditions tend to be more challenging. The team says [...]

Heatwaves over the four hottest months of the year lead to more than 150,000 deaths around the world each year, according to research led by Monash University which looked at deaths over 30 years going back to 1990. The authors say this equates to 236 deaths per 10 million residents or around 1% of all deaths. The authors say this suggests that heatwaves account for about 30% of all heat-related deaths each year, suggesting protecting people during heatwaves could be a cost-effective strategy [...]

Two new electric eel species have been identified in the Amazon basin, including one fish with a record-breaking shock, scientists say. Researchers had previously identified only one species of electric eel in more than 250 years of studying the creatures that lurk in South American waters and stun their prey with electric discharges. However, the new genetic and ecological analysis, published Tuesday in the peer-reviewed Nature Communications, identifies a total of three unique [...]
