Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought      (via sciencedaily.com)     Original source 

Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.

Improving statistical methods to protect wildlife populations      (via sciencedaily.com)     Original source 

In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.

Genes provide hope for the survival of Arabia's last big cat      (via sciencedaily.com)     Original source 

The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in Oman, the research team discovered higher levels of genetic diversity in captive leopards across the region. This important genetic resource has the potential for a major role in successful recovery of the Arabian leopard.

Cooperative hunting requires less brainpower than previously thought      (via sciencedaily.com)     Original source 

Through the use of artificial intelligence technology, a team of scientists has shown that advanced cognitive abilities are unnecessary for cooperative hunting. Their findings suggest that cooperative hunting, previously thought to be a complex social behavior seen primarily in mammals such as lions and chimpanzees, can also develop in species with lower levels of cognitive ability.

New data-driven model rapidly predicts dehydrogenation barriers in solid-state materials      (via sciencedaily.com)     Original source 

Researchers have developed a groundbreaking data-driven model to predict the dehydrogenation barriers of magnesium hydride, a promising material for solid-state hydrogen storage. This advancement holds significant potential for enhancing hydrogen storage technologies, a crucial component in the transition to sustainable energy solutions.

Otters, especially females, use tools to survive a changing world      (via sciencedaily.com)     Original source 

Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools -- most of whom are female -- are able to eat larger prey and reduce tooth damage when their preferred prey becomes depleted.

Shedding light on perovskite hydrides using a new deposition technique      (via sciencedaily.com)     Original source 

Perovskite hydrides are promising materials for various emerging energy technologies, but measuring their intrinsic hydride-ion conductivity is difficult. In a recent study, researchers address this issue using a novel laser deposition technique in an H-radical atmosphere. Using this approach, they grew thin-film single crystals of two different perovskite hydrides and characterized their hydride-ion conductivity. These efforts will bolster research on hydrogen-related materials.

Tiger beetles fight off bat attacks with ultrasonic mimicry      (via sciencedaily.com)     Original source 

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by showing that tiger beetles use ultrasonic warning signals that mimic those of toxic moths.

Parasitic worm likely playing role in decline of moose populations      (via sciencedaily.com)     Original source 

A parasitic worm that can infest the brains of moose appears to be playing a role in the decline of the iconic animal in some regions of North America. Moose populations have been dwindling for years across the country due to many contributing factors, but new research has found the impact of Eleaophora schneideri, also known as the arterial worm, has likely been underestimated.

Climate change is most prominent threat to pollinators      (via sciencedaily.com)     Original source 

A new article has found that climate change is the most prominent threat to pollinators -- such as bumblebees, wasps, and butterflies -- who are essential for biodiversity conservation, crop yields and food security. The research suggests that many of the threats to pollinators result from human activities.
