This network strategy helps facilitate the formation and maintenance of social relationships, even after years apart.
Research suggests that great-tailed grackles, a species expanding its range across the US, possess high levels of behavioral flexibility. This trait enables them to adjust their foraging behaviors and exploit human-provided resources. However, sociability and habitat use were not strongly correlated with flexibility.
A recent study by researchers at Kyoto University found that dogs across all age groups did not exhibit preferences for generous or selfish individuals, despite their ability to eavesdrop on another dog's interactions. This suggests that reputation formation may be more complex than previously thought in animals like dogs.
Researchers report 34 incidents of orcas offering food to humans, including instances where they approached people on the water or on shore. This behavior may indicate orcas' interest in building relationships with humans.
Researchers found that male mosquito brains respond to a wider range of sounds than females and have more diverse responses. This suggests that males use complex acoustic cues to locate females in noisy environments, making traditional traps less effective.
Researchers found that some shark bites are motivated by self-defense when sharks feel threatened or provoked. This discovery challenges the common perception of sharks as mindless predators and highlights the importance of respecting their space.
Understanding how dominance and tribal instincts fuel division is critical to addressing global conflicts and economic inequality. Professor Jorge A. Colombo argues that fundamental behavioural drives are hardwired into our species and continue to shape human behaviour today.
Researchers mapped the precise brain mechanisms that enable animals to overcome instinctive fears, revealing two key components in this learning process. The study found that a brain structure called the ventrolateral geniculate nucleus (vLGN) stores learning-induced memories and is triggered by the release of endocannabinoids.
A new study has discovered that close spatial proximity serves as an indicator of friendship in feral female buffalo, with individual personalities playing a key role. The research found that buffalo with similar social tension, vigilance, and general dominance traits tended to spend more time together.
Researchers found chimpanzees of all ages displayed contagion of grooming and playful behaviors, with younger chimps more susceptible to play contagion. This behavioral contagion may help strengthen social bonds by reinforcing friendly behaviors.
A team of researchers created the first brain-wide map of prairie voles during mating and pair bonding, discovering 68 distinct brain regions active across seven circuits. The study found that male ejaculation elicits a profound emotional state in both males and females, coordinating the formation of a bond.
Researchers at Imperial College London found that specific brain cells in the prefrontal cortex trigger mice to prepare for bed when tired, a behavior likely shared with humans. This hard-wired survival feature suggests that humans should prioritize sleep hygiene to maintain good health.
Researchers found that humpback whales have a unique response to wind noise, singing louder in noisy conditions. In contrast, they do not exhibit an increased reaction to vessel noise from boats. This finding has implications for understanding whale behavior and potential consequences for breeding practices.
Researchers discovered that great apes deliberately spin themselves to dizzy, mimicking human behaviors like whirling dervishes. This study suggests that humans may have inherited the need for altered states from their evolutionary ancestors.
A new study has found that zebrafish larvae increase their chances of escape by moving at an angle perpendicular to the predator's direction. The study also examines the role of environmental noise and biomechanical constraints in shaping behavioral responses.
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 analyzed 105 cat interactions to categorize them into playful, aggressive, or intermediate groups. The majority (56.2%) were classified as playful, while 28.6% were agonistic. Intermediate behavior was observed in 15.2% of cats, exhibiting characteristics of both play and aggression.
A recent study by a transdisciplinary research team found ample evidence of the negative effects of light pollution on migrating animals, but also areas where more data is needed. The researchers concluded that there's a need for more data to help protect migrating animals, particularly species other than birds.
A study by Oregon State University found that dogs with owners who have high expectations and respond well to their behavior are more social, secure, and persistent problem solvers. The research suggests that understanding a dog's needs is crucial for raising secure and resilient dogs.
A new study finds that neon goby parents help their offspring develop by pushing them out the door at the right time. Offspring hatched by parents are larger and more developed than those that hatch on their own, suggesting a complex parenting behavior. This discovery highlights the surprising complexities of fish parenting behavior.
Researchers found that cats' damage to catnip releases higher amounts of strong insect repellents, which are 10-fold higher than from intact leaves. This altered iridoid mixture promotes a prolonged response in cats, effectively repelling mosquitoes.
Researchers found that genetic relatedness correlates with hormonal responses and behavioural reactions in fish, allowing for selective breeding of less-stressed fish. This approach could simplify breeding methods for aquaculture and aquariums.
A new study published in the Journal of Dairy Science found that Norwegian Red calf personality is related to feeding behavior and growth, with calves displaying different traits affecting their milk and concentrate intake. Calves weaned based on individual concentrate intake had higher average daily gains postweaning.
Young dairy calves are motivated to seek full social contact, even with partial interaction, according to a new study. The researchers found that calves pushed more weight to access pens with a social partner compared to empty pens, highlighting the importance of socialization for calf development.
Research reveals Japanese macaques in Kamikochi feed on aquatic insects and molluscs, supplementing their winter diet with high-nutritional value food sources. The unique behavior is attributed to the region's topography and hydrological environment, providing a stable food source for the macaques.
In a study published in Scientific Reports, researchers found that Japanese macaques in the Kamikochi area of Chubu Sangaku National Park eat live brown trout and other freshwater animals to stay alive during harsh winters. The discovery reveals a new adaptation mechanism for these monkeys to cope with extreme conditions.
Researchers from Wellesley College discovered that honey bees (Apis cerana) produce unique sounds, including 'antipredator pipes', to warn fellow bees of giant hornet threats. These signals result in increased bee activity and defense actions against the attackers.
Researchers at the Sainsbury Wellcome Centre have discovered a new brain circuit that enables mice to override their instincts based on previous experience. The ventral lateral geniculate nucleus (vLGN) inhibits threat reactions when animals feel safe, but activates them when danger is perceived.
A new study by the University of Exeter reveals that domestic cats rely almost entirely on their owner-provided food for nutrition. Despite being prolific hunters, cats only consume a small percentage of the prey they catch.
Researchers captured footage of a tortoise attacking and killing a tern chick on Frégate Island. The tortoise approached the chick with its jaws open, suggesting it was an experienced hunter. This unusual behavior challenges previous assumptions about tortoises' diets and hunting habits.
A new study published in Nature shows that rodents rely on a combination of innate instincts and learning to recognize unique infant cries. Experienced caregivers were found to be more effective at identifying subtle variations in distress calls and retrieving crying pups, while inexperienced animals required extensive training.
Researchers at EMBL have traced the physical connection between the prefrontal cortex and brainstem that inhibits instinctive behavior. The study found that this connection, specifically to the PAG region of the brainstem, prevents social animals from acting out impulses.
A new UT study suggests that prey emit warning cues to survive and also help predators avoid danger. The theory proposes a mechanism called concurrent reciprocal selection, where both prey and predators benefit from the signals, ensuring their survival.
A study published in Current Biology found that people's reactions to repulsive images can forecast their political orientation. The strength of a person's reaction was enough to predict an individual's political ideology with high accuracy. This research suggests that neural responses associated with disgust may be inherited and linke...
Female ants and bees are more inclined to care for the queen's offspring due to their maternal behaviors preserved through evolution. This study reveals that females take on jobs suited historically, leading to the evolution of species with female-dominated caregiving roles.
Neuroscientist Joseph LeDoux suggests that studying animal survival instincts can provide insights into human emotions. By analyzing brain functions used for survival, researchers may gain new understandings of both humans' and animals' emotional responses.
A study published in the Proceedings of the National Academy of Sciences found that addictive drugs may hijack the same nerve cells and connections as salt appetite in the brain. This could explain why addiction treatment with abstinence is so difficult, and offers new approaches to addiction research.
A new study suggests that unhappy consumers are more likely to crave tactile experiences, such as hugging a teddy bear, to alleviate negative emotions. This is because their brain systems mimic those of mammals, which prioritize comfort and security in times of stress.
