The double-edged effect of environmental fluctuations on evolutionary rescue [0.03%]
环境波动对进化救援的双刃剑效应

Recent studies revealed that contemporary evolution can prevent population extinction in deteriorating environments. Such evolutionary rescue has been intensively studied, but few have focused on environmental fluctuations. As global change...

The existence of substantial additive genetic variance in fitness poses a long-standing question for evolutionary geneticists. A new theoretical paper by Connallon & Czuppon examines the effect of random genetic drift and temporal fluctuati...
Wing length canalisation and behaviour across birds: a phylogenetic meta-analysis of variance [0.03%]
基于系统发育的方差元分析：鸟类翅长的等势分布及其行为效应

We examined the expectation that stronger stabilising selection leads to a decrease in trait variation across species by investigating individual variation in wing length. We hypothesised that species that heavily rely on aerial feeding, as...
Pollinator assemblage composition predicts trait divergence in a pollination-generalized plant [0.03%]
访花昆虫群落组成预测了定植于广泛传粉生态位上的植物的性状分化趋势

Felipe Torres-Vanegas et al.
The causal role of pollinators in driving the divergence of plant traits is a fundamental tenet of angiosperm evolution, providing hallmark examples of natural selection. However, it remains unclear how geographic variation in pollinator as...
Caenorhabditis diversity on Pohnpei, Micronesia, provides evidence that the Elegans Supergroup has its roots in the Americas and diversified in the Pacific en route to Asia [0.03%]
密克罗尼西亚波纳佩岛上芽胞杆菌的多样性表明，优雅超谱系起源于美洲并在太平洋地区向亚洲辐射扩散的过程中多样化发展

Model organisms are powerful tools for discovery in cell and molecular biology, and studies of their natural history have the potential to provide bridges between these fields and ecology and evolutionary biology. The nematode Caenorhabditi...

Experimental evolution is a powerful method that has been instrumental for revealing core mechanisms of adaptation and coevolution. It has mostly been used in very simple settings of one or two species. Yet, it is now increasingly being emp...
Digest: Population-level processes that facilitate divergence differ between Andean and Amazonian birds [0.03%]
概要：安第斯山脉和亚马逊地区的鸟类在分化过程中，群体层面的促进机制不同

Pranav Gokhale
Wacker and Winger (2026) examine population-level divergence across two very different but connected landscapes, the Andes and the Amazon, using genomic data from eight Tangara bird species. Andean populations show strong genetic structure,...
Addressing multi-generational non-genetic responses in experimental studies of evolution [0.03%]
实验进化研究中多代非遗传反应的产生及应对措施
Giacomo Zilio,Stéphanie Bedhomme,Emanuel A Fronhofer et al.
Giacomo Zilio et al.
Populations that face environmental change reducing their mean fitness can recover by adaptive genetic evolution over multiple generations, but their immediate responses may also involve non-genetic mechanisms, though the latter can be diff...
The land-to-water transition impacts brain shape in caniform carnivorans [0.03%]
陆生到水生的转变影响伪熊科食肉动物的大脑形状
Thomas M B Kirkwood,Susanne Shultz,Mary T Silcox et al.
Thomas M B Kirkwood et al.
Mammals exhibit remarkable diversity in brain size and morphology, resulting from numerous ecological radiations throughout the Cenozoic. Although previous studies have demonstrated the influence of phylogeny, allometry, and various ecologi...
A quantitative genetics analysis of evolution in the hominoid appendicular skeleton [0.03%]
类人猿附肢骨骼进化定量遗传分析
Marianne J Cooper,Mark A Conaway,Noreen von Cramon-Taubadel
Marianne J Cooper
Hominoidea are a diverse superfamily, with potential selection on the postcranium from divergent locomotor patterns. The scarcity of postcranial primate fossil remains, however, means that selection on the appendicular skeleton has been dif...
