Chemical communication is a key mechanism for modulating social and reproductive behaviours. Among the most studied chemical signals are the sodefrin precursor-like factors (SPFs), a group of pheromones that enhances reproduction receptivit...

Antagonist interactions, such as predator-prey interactions, are widespread in nature and drive both ecological and evolutionary outcomes. Coevolutionary outcomes of antagonistic interactions have been shown to be influenced by environmenta...
Coastal and inland American alligators (Alligator mississippiensis) diverge along physiological axes in response to a salinity gradient [0.03%]
响应盐度梯度美洲短吻鳄的生理学特征在沿海和内陆地区出现差异

Ecotypes often occupy an environmental gradient, which can lead to divergence in physiological traits between ecotypes. We tested the hypothesis that alligators from inland and coastal environments have physiologically and genetically diver...

Social interactions mediate the phenotypic expression of fitness-relevant traits. The expression of such labile social traits includes three distinct components: an individual's mean trait value (direct effect), its social responsiveness, a...
Ancestral Wolbachia lineages are likely donors of ribotoxin genes in Aedes aegypti [0.03%]
登革热媒介蚊Aedes aegypti中的棒状杆菌内共生菌的谱系与核糖毒素基因的关系研究

Walter J Lapadula Wj et al.
Ribosome-inactivating proteins (RIPs) are enzymes that irreversibly inhibit protein synthesis by depurinating a specific adenine residue in the ribosomal RNA. Although members of this gene family are widespread in plants and bacteria, their...
Sexual selection on males predicts reduced mitochondrial genetic diversity across mammals [0.03%]
雄性的性选择预测哺乳动物的线粒体遗传多样性减少

Sexual selection on males is expected to reduce genetic diversity via paternal inheritance because increased variance in male reproductive success lowers the male effective population size. It is plausible that sexual selection on males als...
Ecological harshness has a weak influence on reproductive trade-offs in a great tit population [0.03%]
生态恶劣条件对大山雀种群的繁殖权衡影响较弱

Lack's seminal work on bird clutch sizes has spurred expansive research on reproductive trade-offs, especially focusing on offspring quantity-quality trade-offs and the potential fitness consequences for the parents. The environment is a cr...
A field experiment assessing the roles of drought, herbivory, and local climate on cyanogenesis cline formation and local adaptation in Trifolium repens [0.03%]
一项实地实验评估了干旱、植食作用以及地方气候在白三叶草氰苷含量cline形成及地方适应性中的作用

Projecting how populations will adapt to environmental changes requires a mechanistic understanding of selection imposed by various biotic and abiotic factors. In white clover (Trifolium repens), clines in an antiherbivore defense mechanism...
Identifying the proximate mechanisms that generate plasticity in fecundity for nutrition in Drosophila melanogaster [0.03%]
揭示营养对果蝇(Drosophila melanogaster)繁殖力可塑性影响的机制

Nutrition is an important determinant of an animal's survival and fitness. Phenotypic plasticity allows a genotype to adjust life history traits to changes in its nutritional environment, and it varies among individuals. To understand how v...

Under the strong selective pressure of parasitism, hosts have evolved the strategy to recognize and reject parasitic eggs or chicks. Although studies have shown that hosts use multiple egg recognition mechanisms, it remains unclear whether ...
