Maternally transmitted endosymbionts of arthropods are common and phylogenetically diverse. Several bacteria, including Wolbachia and Cardinium, have independently evolved the ability to induce cytoplasmic incompatibility (CI) limiting the ...

Phenotypic plasticity enables organisms to produce better-suited phenotypes when the environment changes, improving fitness under adverse conditions. Yet responding to environmental cues may provide little use in a constant environment, whe...

The evolution of novel animal signals is critical to the generation of biodiversity. Here, we explore how new sexual signals become established. This process is challenging to explain because if receiver preferences are coupled with existin...
The effects of sexual selection on functional and molecular reproductive divergence during experimental evolution in seed beetles [0.03%]
性选择对实验进化过程中种子甲虫功能和分子生殖分歧的影响

Salomé Fromonteil et al.
Sexual selection can be an engine of divergent evolution between closely related lineages, as a result of idiosyncratic coevolution of male and female reproductive traits. The possibility that this can contribute to speciation has ample sup...
Fast females, slow males: accelerated ageing and reproductive senescence in Drosophila melanogaster females across diverse social environments [0.03%]
雌快雄慢：果蝇(Drosophila melanogaster) 女性在多样化的社会环境下的快速衰老和生殖力下降

Females and males typically differ in lifespan, patterns of ageing, and reproduction. General explanations for variation in the magnitude of this sex-specificity remain elusive, and the role of the social environment in this context is unde...
Live birth in lizards: A process-based model for the roles of temperature, behavior, and life-history [0.03%]
温度、行为和生活史对蜥蜴活胎生过程的作用机制模型研究

Guillermo Garcia-Costoya et al.
Life-history traits evolve to optimize fitness trade-offs across an organism's life cycle. Potentially to mediate the trade-off between survival and fecundity, multiple animal groups have independently evolved live birth (viviparity), inclu...
Historical contingency limits adaptive diversification in a spatially structured environment [0.03%]

Understanding how genotype-by-environment (G × E) interactions influence evolutionary trajectories and contribute to historical contingency is key to predicting adaptation. In structured environments, populations often diversify into ecoty...
Joint test of historical vs. contemporary biogeography supports abundant center hypothesis shaping spatial patterns of self-fertilization [0.03%]

Plant reproductive assurance describes the ability of a plant to successfully reproduce in an environment that is potentially devoid of conspecifics and/or pollinators. Traditionally, studies have focused on contemporary ecology-pollinator ...
Can the right partner mitigate harm? Rhizobial strains vary in their mediation of herbicide stress in a plant-rhizobia mutualism [0.03%]

Agriculture has intensified the presence of chemical stressors in the rhizosphere-the region surrounding roots where critical plant-microbe interactions occur, such as those between leguminous plants and nitrogen-fixing rhizobial bacteria. ...
Gestation length both shapes and is shaped by other life history traits in terrestrial eutherian mammals [0.03%]
胎盘哺乳动物的妊娠期既塑造了生活史其他性状又受到其他性状的影响
Thodoris Danis,Dana Lin,Daniel S Caetano et al.
Thodoris Danis et al.
The length of gestation in eutherian mammals, which is key to their reproductive success, is closely connected to other life history traits, body mass, and brain mass, but the direction of relationships between these variables is unclear. H...
