Ecological niches are closely intertwined with cognition in many animal lineages. For example, diet breadth is linked with performance on tasks measuring learning and exploration in several vertebrates, with generalists often exhibiting fas...
Enhanced conspicuousness of prey in warmer water mitigates the constraint of turbidity for predators [0.03%]
温暖水域中猎物更显眼可缓解浑浊度对捕食者的制约作用

Changes in environmental conditions impact predator-prey interactions by altering behavior through sensory and non-sensory (eg metabolic or cognitive) pathways. Elevated water temperature and turbidity are known to alter activity levels and...
No evidence for kin selection as an explanation for social group formation in clown anemonefish [0.03%]
无证据表明亲属选择可以解释小丑刺豚鱼社会群体形成的机制

Social groups in which some individuals forgo reproduction and others reproduce, are one of the most remarkable products of evolution. To fully understand these social groups, we must understand both why non-breeders tolerate their situatio...

We investigated the influence of relatedness on the function of dyadic butting contests over access to a food resource (plant phloem) in the group-living horned aphid Astegopteryx bambusae on bamboo leaves. Relatedness between dueling pairs...
Wind alters plant-pollinator community structure, bee foraging rate & movements between plants [0.03%]
风改变植物-传粉者群落结构、蜜蜂采食速率及植株间移动行为

Wind is an important abiotic factor that influences an array of biological processes including animal behavior, but it is rarely considered in plant-pollinator interactions. Here, we investigate the impact of wind speed on plant-pollinator ...

A widely accepted explanation for the reliability of offspring begging signals assumes a differential benefit model balanced by direct viability costs independent of offspring nutritional condition. However, supporting evidence for this ide...

Noise pollution is a global threat to biodiversity, significantly affecting acoustic communication in birds and other taxa. While European robins (Erithacus rubecula) adjust their songs in response to urban noise during the breeding season,...
Parasitic mussels induce upstream movement in their fish hosts: early evidence of extended phenotype [0.03%]
寄生淡菜使得它们的鱼类宿主向河流上游移动：扩大表型的早期证据

Parasites often have a large impact on their hosts and can alter host phenotype to increase their own fitness, a phenomenon known as extended phenotype. Studies demonstrating extended phenotype for non-trophically transmitted parasites are ...
Diel rhythmicity of activity and corticosterone metabolites in Arctic barnacle geese during breeding [0.03%]

Birds that migrate from temperate areas to the Arctic to breed lose their strongest Zeitgeber of circadian organization when they cross the Arctic circle in spring - the 24h light-dark cycle. Under continuous daylight, diverse behavioral an...
Living with males leads to female physical injury in the leaf-footed cactus bug [0.03%]
与雄性共同生活会导致仙人掌叶足虫的雌性身体受伤

Males in many species possess sexually selected weapons that they use to fight for mating opportunities. It is well established that male-male competition can lead to physical injuries for males. However, very few studies have looked at the...
