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 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.
