Humans rely on a suite of fundamental social motives to navigate recurring adaptive challenges. Using data from 14 532 participants across 42 societies, we examine sex similarities and differences in the strength of these motives across adu...

Human activities generate a variety of novel food sources that wild animals exploit. On land and in water, these human-derived foods can profoundly alter intraspecific interactions in wildlife with cascading effects on population dynamics a...
Recent evolution of large offspring size and post-fertilization nutrient provisioning in swordtails [0.03%]
剑尾鱼中大型后代尺寸和受精后营养供应的近期进化变迁

Organisms have evolved diverse reproductive strategies that impact the probability that their offspring survive to adulthood. Using morphological measurements in embryos and fry, gene expression analysis and hybrid crosses, we describe dive...
Fear generalization: correlated individual differences in response to predator cues, smoke and pesticides [0.03%]
恐惧泛化：对捕食者线索、烟雾和农药反应的个体差异相关性

Organisms face numerous biotic and abiotic threats. Behavioural responses to these threats impact individual fitness and often affect population, community and ecosystem outcomes. Although animals face diverse threats, most studies on behav...

Owing to their precision and predictability, radiogenic isotopes are prized for tracking the movement of terrestrial and freshwater species, as well as the origins of natural products. Yet, their use in marine systems is rare. Here, we inve...

Relatively few clades have colonized the deep sea. Here, we analyse evolutionary pathways into this harsh environment, as a continuum defined by two potential endmembers-a 'piecemeal model', with exclusively deep-sea species (deep-sea endem...
Sibling interference in mother-offspring interactions reveals jealous reactions in wild baboons [0.03%]
野生狒狒母子互动中的兄妹干扰揭示了兄弟姐妹的嫉妒反应

Whether non-human animals can experience complex emotions like jealousy remains debated. In humans, jealousy is particularly salient in sibships, where children often disrupt affiliative parent-sibling interactions. Jealousy could similarly...
Evolutionary convergence and trophic diversity in hot vent and cold seep shrimps showcase a continuum of symbiosis [0.03%]
热液和冷泉虾的趋同进化与营养多样性展示了共生的连续性

Convergent evolution offers a powerful lens through which to examine the selective forces shaping life in extreme environments. In deep-sea hot vents and cold seeps, invertebrates have independently evolved symbioses with chemosynthetic bac...
Trait-mediated effects of anthropogenic noise on bird behaviour and fitness [0.03%]
人为噪声对鸟类行为和适应性的性状介导效应

Birds are considered especially vulnerable to anthropogenic noise because of their reliance on acoustic information. Single-species research shows that noise can impact different aspects of bird behaviour and consequently reduce their fitne...

The current understanding of proximodistal axis patterning in arthropod legs is grounded in insect models. The paradigm for appendage evolution in this phylum is that the gene regulatory network responsible for leg subdivision and patternin...
