To avoid these dead ends, the researchers emphasize the need for collective human agency and design settings where it can flourish.
Researchers studied mountain goats' behavior in Glacier National Park, finding that ear flicks showed a strong correlation with the presence of snow. The lack of summer snow patches may increase their risk of local extirpation due to increased tick infestations.
Researchers found that chimpanzees are more likely to climb hills when heading towards contested borders, where they can quietly rest and hear distant sounds of rival groups. This behavior suggests that chimpanzees gauge the distance of rivals and act accordingly to avoid costly fights.
A study published in PLOS ONE found that roosters can recognize their mirror image and respond accordingly. The researchers tested 58 roosters and found that they emitted alarm calls when seeing themselves in the mirror, but not when seeing a conspecific. This suggests that roosters may have some level of self-awareness.
Researchers found that exposure to the aggregation pheromone 4,8-dimethyldecanal reduces death-feigning duration in red flour beetles, allowing them to save time and increase survival chances. Sex-related differences in death feigning behavior were also observed, with males exhibiting longer durations.

Researchers found that mothers' social environment predicts their sons' reproductive tactics, such as sneaking or guarding females. A biased female sex ratio in the maternal generation leads to increased male-male competition, resulting in more males and intense mating behaviors.
A 10-year study found that golden-crowned sparrows resettled an average of just 90 feet away from the center of their previous year's range when returning to California after winter migration. The study suggests that social bonds and familiar faces help anchor the birds to specific spaces, even when resources are scarce.

The Southern Resident killer whale population is spending far less time in the San Juan Islands as their primary food source, Chinook salmon, declines. This decline is likely an effort to find alternative food sources, and research shows a strong relationship between the whales' presence and salmon returns.
A recent study published in The Science of Nature found that parasites and body condition are crucial factors in determining the vulnerability of fish to angling. The research revealed that fish with high body condition and parasites, as well as those with low body condition but no parasites, were less likely to be caught by anglers.
New research suggests brown widow spiders actively seek and kill nearby black widows, displacing them in parts of the southern US. Brown widow females are also larger and more fertile than black widows, with a higher reproductive success rate.
Researchers have discovered unexpected similarities between stone tools used by monkeys and some of the earliest hominin stone artifacts. The findings suggest that accidental production of stone fragments during nut cracking may hold clues to the origin of intentional tool use in early humans.
Research from the University of Cambridge and Cardiff University found that damselfish scare off cleaner fish customers, leading to fewer species receiving vital cleaning treatment. This disruption could contribute to the breakdown of delicate ecosystems supported by coral reefs.
A study by Osaka Metropolitan University found that fish recognize themselves in photographs based on their faces, not bodies. The cleaner fish attacked photos with unfamiliar faces but not their own, indicating a higher sense of self awareness.

Biologists found songbirds can assess when predation risk from northern pygmy owls is highest and when there's safety in numbers. Mobbing behavior peaked in late summer and autumn when young birds are most vulnerable.
Researchers found muskies' size, boldness, and exploration levels are linked to their likelihood of striking. Anglers should prioritize catch-and-release and best practices to protect these traits.
A study by Oregon State University researchers found that synchronized fishing with dolphins in Brazil increases the number of fish caught and supports both species' survival. The cooperative relationship is specific to this population of dolphins and has been passed down through generations of fishermen.
Scientists found that invasive black rats transform reef fish behavior, causing changes in territorial patterns and nutrient cycles. The presence of rats disrupts the nutrient cycle by reducing seabird populations and nutrients deposited onto islands.
A recent study by Lancaster University found that coral bleaching events alter the behavior of butterflyfish, making it harder for them to recognize competitor species. This change leads to poorer decision-making, resulting in wasted energy and increased aggression.
Spotted hyenas show that twin brothers and buddies from the same birth group very often disperse together to breed. This coordination is likely due to similar preferences and social backgrounds. The frequent joint dispersal among twins and buddies has major consequences for understanding social dynamics and gene flow in wild populations.
Researchers analyzed coyote diets and movement in Cape Breton Highlands National Park to determine why a lone hiker was attacked. The study found that coyotes relied on moose due to resource scarcity, adapting their behavior to exploit this unusually large food source.

A large wingless wood-eating cockroach unique to Australia's Lord Howe Island has been rediscovered at the foot of a single Banyan tree. The species was thought extinct since the 1930s, but its genetic difference from offshore relatives suggests it may have survived due to co-evolution with ground-dwelling insects.
Researchers at NTNU studied zebrafish brain activity while increasing temperature, finding that brains completely stopped responding to stimuli but then 'lit up' when temperatures reached extreme levels. Adding oxygen improved thermal tolerance and recovery rate in fish, suggesting a key role for glial cells in regulating oxygen supply.
