Unequal breeding sex ratio can significantly reduce effective population size, allowing a rare neutral allele to jump to a high frequency through genetic drift. However, this one-way alteration to allele frequency appears inconsistent with ...
Can extreme climatic events induce shifts in adaptive potential? A conceptual framework and empirical test with Anolis lizards [0.03%]
极端气候事件能否引发适应潜能的变化？基于安乐蜥的概念框架和实证测试

Multivariate adaptation to climatic shifts may be limited by trait integration that causes genetic variation to be low in the direction of selection. However, strong episodes of selection induced by extreme climatic pressures may facilitate...

Aposematic species combine a conspicuous signal with a secondary defence, the majority of which are studied in the context of a visual signal. While multimodality of the aposematic signal appears to be common in invertebrate species, we kno...
Strong phylogenetic congruence between Tulasnella fungi and their associated Drakaeinae orchids [0.03%]

The study of congruency between phylogenies of interacting species can provide a powerful approach for understanding the evolutionary history of symbiotic associations. Orchid mycorrhizal fungi can survive independently of orchids making co...
Mutation and selection processes regulating short tandem repeats give rise to genetic and phenotypic diversity across species [0.03%]
短串联重复序列的突变和选择过程在各物种中产生遗传和表型多样性

Short tandem repeats (STRs) are units of 1-6 bp that repeat in a tandem fashion in DNA. Along with single nucleotide polymorphisms and large structural variations, they are among the major genomic variants underlying genetic, and likely phe...
Direct and indirect phenotypic effects on sociability indicate potential to evolve [0.03%]
直接和间接的表型效应影响社交行为表明存在进化潜力

The decision to leave or join a group is important as group size influences many aspects of organisms' lives and their fitness. This tendency to socialise with others, sociability, should be influenced by genes carried by focal individuals ...
To self or not to self? Absence of mate choice despite costly outcrossing in the fungus Podospora anserina [0.03%]
自交还是不自交？尽管异交代价高昂，但拟散囊菌中并未出现交配选择现象

Fungi have a large potential for flexibility in their mode of sexual reproduction, resulting in mating systems ranging from haploid selfing to outcrossing. However, we know little about which mating strategies are used in nature, and why, e...
Within-population variation in body size plasticity in response to combined nutritional and thermal stress is partially independent from variation in development time [0.03%]
营养和热应力下响应体型可塑性组内变异部分独立于发育时间的变异

Ongoing climate change has forced animals to face changing thermal and nutritional environments. Animals can adjust to such combinations of stressors via plasticity. Body size is a key trait influencing organismal fitness, and plasticity in...

Coupling of multiple barriers to gene-flow, such as divergent local adaptation and reproductive isolation, facilitates speciation. However, alleles at loci that contribute to barrier effects can be dissociated by recombination. Models of li...
Genetic architecture of multiple mutualisms and mating system in Turnera ulmifolia [0.03%]

Plants often associate with multiple arthropod mutualists. These partners provide important services to their hosts, but multiple interactions can constrain a plant's ability to respond to complex, multivariate selection. Here, we quantifie...
