Coevolution of species' range borders: Interactions between interspecific competition, gene flow, and matching habitat choice [0.03%]
物种分布范围边界的协同进化：种间竞争、基因流动和适宜生境选择匹配之间的相互作用

Farshad Shirani
Existing theory examining the coevolutionary dynamics of species' range borders assumes random dispersal, which causes maladaptive gene flow from the range core to the range margins and contributes to the formation of range limits. However,...
Migration patterns and hybridization within the Asian stonechat complex in response to a major geographical barrier [0.03%]
响应主要地理屏障的亚洲石鸟杂交模式及其迁移规律

Tianhao Zhao et al.
Facing geographical barriers, phenotypic responses of migratory landbirds may differ even between closely related taxa: some may bypass barriers while others cross them. Such phenotypic variation can arise from different genetic backgrounds...
Causal attribution by the chain rule: unifying natural selection, learning, economics, and other disciplines [0.03%]

Analysis often splits change into components. For example, how much of the observed variance is caused by genes or environment? In many cases, the split is ultimately made by the logic of the chain rule, which divides the difference of a pr...
Additive effects of environmental and demographic variation shape the repeatability of evolution across replicated experiments [0.03%]
环境和人口因素的累积效应决定了进化在重复实验中的重现性

Karen Bisschop et al.
The repeatability of evolution is fundamentally important for understanding the origin and diversification of life as well as for developing evolutionary forecasting tools. Repeatability is limited by stochasticity, here defined as changes ...

Samuel Te Greenrod et al.
Temporal thermal heterogeneity is expected to favour intermediate, generalist phenotypes that can maintain growth across a broad thermal range but have sub-optimal growth at any single temperature. Yet, thermal variation typically occurs in...
Sexual antagonism, mating systems, and recombination suppression on sex chromosomes [0.03%]
性对抗、交配系统和染色体上的重组抑制作用
Ewan Flintham,Charles Mullon
Ewan Flintham
The suppression of recombination between sex chromosomes is a widespread feature of genetic sex determination systems. Competing explanations for this evolution fall into two broad categories: recombination arrest driven by the capture of s...
The legacy of past climate warming: strong local adaptation in rear-edge populations [0.03%]
过去气候变暖的遗留效应：后边缘种群中的强局部适应性
Antoine Perrier,Olivia J Keenan,Jeremiah W Busch et al.
Antoine Perrier et al.
Improving forecasts of species' responses to climate change has become a central challenge in ecology and evolution as species distributions are increasingly disrupted by ongoing climate warming. Insight into this challenge may be gained th...
Evidence for balancing selection on loci associated with host use in the genome of a generalist plant parasite [0.03%]
寄主利用位点平衡选择的证据：以一般性植物病原体为例
McCall Calvert,Alison Chen,Adya Gupta et al.
McCall Calvert et al.
Most research on host-parasite interactions has focused on tightly coevolved species pairs, yet many parasites are generalists that infect a wide range of host taxa. Generalist parasites are subject to highly variable selection pressures ac...

Ruth G Shaw et al.
The rapid pace of environmental change has prompted pressing concerns about the persistence of wild populations. For plants, because they move from one place to another only passively between generations, their persistence is especially lik...
Increased adaptive potential in novel environments can be predicted from genetic variance in development time expressed in native environments [0.03%]
在原生环境中表达的发育时间遗传变异可以预测在新环境中的适应潜力提升
Greg M Walter,Keyne Monro,Alastair Wilson et al.
Greg M Walter et al.
While developmental plasticity helps organisms to maintain fitness as environments change, such plasticity has limits. When novel environments exceed these limits and mean fitness declines, the extent of decline is expected to vary among ge...
