Research at Duke University found that older male swamp sparrows sing less frequently and consistently, leading other males to approach them closer. This suggests that a decline in song quality may indicate to other males that an aging rival is no longer a threat.
Squid exhibit strong alarm behaviors when exposed to underwater pile driving noise, which can be associated with offshore wind farms. The study found that fast habituation may make squids more vulnerable to predation, while longer periods between pile driving activity may discourage long-term habituation.
Researchers observed a dramatic shift from chaotic to ordered motion in jackdaw mobs as they grew in density. The birds initially follow 'topological' rules for winter roosting but switch to 'metric' rules for predator avoidance, leading to the emergence of organized behavior.

By examining couples' homes and community designs, scientists can identify patterns that promote healthier behavior and positive experiences among occupants.
Researchers at the University of Michigan discovered that paper wasps possess the ability to use known relationships to infer unknown ones, similar to humans. This cognitive skill may be linked to their complex social behavior and dominance hierarchies, allowing them to rapidly make deductions about novel social relationships.
Researchers monitored microchipped rats in the presence of feral cats, finding that rats avoided cats and spent more time in burrows, contradicting popular opinion about cat-rat interactions. The study adds to growing evidence that releasing cats to control city rats is outweighed by threats to urban wildlife.
Researchers found that boldness in male and female yellow-spotted monitor lizards was associated with higher mating success. However, this boldness came with a cost: exposed individuals were at a higher risk of being eaten by predators during the wet season.

A new study found that small and hungry prawns are more likely to innovate when in a group, while size has no effect alone or with hunger. This challenges the long-held notion that necessity drives innovation.
A new study reveals that demarketing can be an effective way to reduce carbon footprint by altering consumer values. Materialistic individuals tend to decrease their consumption after reading a report about overconsumption, whereas those with low materialism may increase their consumption in response to social norms.
Researchers discovered that mongoose cooperativeness lasts a lifetime, with consistent individuals helping offspring care and those with selfish personalities not increasing their workload. The study found varying personality types among mongooses, which remain unknown.
Researchers found that 18% of wild banded mongoose pups are fathered by males from rival packs, reducing the risk of inbreeding. Female mongooses take risks to mate with rivals during pack 'warfare', while males discriminate between relatives and non-relatives.
A new study found that cat owners are unaware of the number of animals killed by their pets and resist control measures. Despite this, many owners agree to neutering as a method of improving cat welfare.
A new study from the University of Exeter has found that racehorse speeds have improved greatly since 1850, with increases in speed greatest in shorter distance races. The researchers used a large data set of racing records to analyze thoroughbred performance at the elite level and found that horses are getting faster.
Researchers found that male flour beetles can detect chemical cues on females indicating sperm competition and adjust their courtship efforts accordingly. When females exhibit the scent of one to three rival males, males increase their reproductive investment.
A new study published in Behavioural Ecology found that elderly crickets' behavior becomes more entrenched with age, making them less responsive to changing environmental conditions. This suggests that older individuals may struggle to adapt to changes in climate, habitat, or diet, potentially affecting their survival prospects.
A unique combination of ecological, environmental, and behavioral factors led to the abundant production and preservation of Early Triassic swim tracks. Delayed ecologic recovery, depositional environments, and tetrapod swimming behavior contributed to their formation.

Researchers observed varying activity levels among jumping spiders and house crickets, finding that combined personality types best predicted survival for crickets and foraging success for spiders.
In a study of gray tree frogs, females preferred calls that were longer and more frequent, which is a challenging task. The findings support the multitasking hypothesis, suggesting that high-quality males can produce multiple signals at once.
A new study published in PLOS ONE reveals unique social interactions among great white sharks while scavenging on dead whales in South Africa. The team observed 40 different sharks feeding on a carcass over a single day, suggesting that shark populations may rely on scavenging to supplement their regular feeding activities.
A study by behavioral ecologist John Hoogland found that prairie dogs are more likely to disperse in the absence of nearby close kin. This unique pattern is attributed to the benefits of cooperation with close kin, including shared resources and defense against predators.
Researchers studying the endangered lemur found that females live longer than males, on average into their early 30s. The team's findings suggest that age-specific dispersal behavior may carry greater costs for males, leading to earlier mortality.
Researchers found that fish exposed to anxiety-moderating drugs like Oxazepam became bolder and less social, leading to changes in their hunting behavior. This can have serious ecological consequences, including disturbance of the balance in aquatic environments.
