Natural populations often experience heterogeneity in the quality and abundance of environmentally acquired resources across both space and time, and this variation can influence population demographics and evolutionary dynamics. In this st...

Polyploids are organisms with three or more chromosome sets, which often give them different physiology, morphology, and evolutionary properties. The impact of polyploidy on the genetic load dynamics, in terms of accumulation, fixation, and...
Gene expression evolution is predicted by stronger indirect selection at more pleiotropic genes [0.03%]
更具多效性的基因会受到更强的间接选择从而预测其表达进化方向

Changes in gene expression levels are central to adaptation, yet predicting and understanding their evolution remains challenging. Here, we used transcriptome-wide variation in the red flour beetle Tribolium castaneum to identify genes unde...
Multivariate trait evolution: models for the evolution of the quantitative genetic G-matrix on phylogenies [0.03%]
多变量性状进化：定量遗传G矩阵的系统发育模型

Simone P Blomberg et al.
Genetic covariance matrices (G-matrices) are a key focus for research and predictions from quantitative genetic evolutionary models of multiple traits. There is a consensus among quantitative geneticists that the G-matrix can evolve through...
Relative testis size is associated with vagina length but not sperm storage traits in Galliformes [0.03%]
Relative testis size与Galliformes的vagina length有关但与sperm storage traits无关

Post-copulatory sexual selection, comprised of sperm competition and cryptic female choice, is a powerful evolutionary force that can drive the rapid diversification of reproductive traits across taxa. In birds, the female reproductive trac...

Understanding the drivers of biodiversity is a central goal in evolutionary biology. In particular, sexual selection has long been proposed as a potential catalyst of speciation, but empirical evidence remains inconclusive. Here, we present...
Early-season helping yields increasing returns to scale at the onset of eusociality [0.03%]
早期助养导致初期eusociality呈规模报酬递增现象

The evolution of eusociality, characterized by cooperative brood care, reproductive division of labor, and overlapping generations, represents a major evolutionary transition. A central paradox is that early models suggested diminishing ret...
An early-life survival and reproductive trade-off shapes selection on body size [0.03%]
早期生存和繁殖之间的权衡塑造了对体型的选择

Maria João Janeiro et al.
Evolutionary trade-offs-opposing trait effects on total fitness via different fitness components-are likely to be widespread. Some key trade-offs are expected to be the result of chains of causation acting across an organism's lifetime. For...
Temporal dynamics and adaptiveness of thermal phenotypic plasticity in a ciliate [0.03%]
纤毛虫热形态可塑性的时空动态及其适应性

Léonard Dupont et al.
Phenotypic plasticity is a widespread strategy used by organisms to cope with environmental fluctuations. Empirical studies have mostly focused on describing the amplitude of phenotypic change through reaction norms, which ignore the tempor...
Rapid temporal adaptation structures tolerance to toxic cyanobacteria in a natural population of the water flea Daphnia [0.03%]
