Contemporary effective population size (Ne) can be estimated using linkage disequilibrium (LD) observed across pairs of loci presumed to be selectively neutral and unlinked. This method has been commonly applied to data sets containing 10-1...
Making sense of the relationships between Ne, Nb and Nc towards defining conservation thresholds in Atlantic salmon (Salmo salar) [0.03%]
厘清保护阈值定义中的有效种群大小、核化种群大小和最小种群大小之间的关系——大西洋鲑鱼(Salmo salar)案例研究

A-L Ferchaud et al.
Effective population size over a generation (Ne) or over a reproductive cycle (Nb) and the adult census size (Nc) are important parameters in both conservation and evolutionary biology. Ne provides information regarding the rate of loss of ...

An open question in evolutionary biology is the relationship between standing variation for a trait and the variation that leads to interspecific divergence. By identifying loci underlying phenotypic variation in intra- and interspecific cr...
Paternity analysis reveals wide pollen dispersal and high multiple paternity in a small isolated population of the bird-pollinated Eucalyptus caesia (Myrtaceae) [0.03%]
父性分析显示,在一种传粉鸟传粉的孤立种群中(桃金娘科巨桉),花粉传播范围广且多雄性交配现象高

N Bezemer et al.
Optimal foraging behaviour by nectavores is expected to result in a leptokurtic pollen dispersal distribution and predominantly near-neighbour mating. However, complex social interactions among nectarivorous birds may result in different ma...
Sex change and effective population size: implications for population genetic studies in marine fish [0.03%]
性别变化和有效种群大小:对海洋鱼类群体遗传学研究的启示

I Coscia et al.
Large variance in reproductive success is the primary factor that reduces effective population size (Ne) in natural populations. In sequentially hermaphroditic (sex-changing) fish, the sex ratio is typically skewed and biased towards the 'f...
Relaxed selective constraints drove functional modifications in peripheral photoreception of the cavefish P. andruzzii and provide insight into the time of cave colonization [0.03%]
relaxed的选择限制驱动了洞穴鱼P. andruzzii周边光感受器的功能修改 并为我们提供了关于其进入洞穴的时间的见解
L Calderoni,O Rota-Stabelli,E Frigato et al.
L Calderoni et al.
The genetic basis of phenotypic changes in extreme environments is a key but rather unexplored topic in animal evolution. Here we provide an exemplar case of evolution by relaxed selection in the Somalian cavefish Phreatichthys andruzzii th...
Genome-wide SNP data suggest complex ancestry of sympatric North Pacific killer whale ecotypes [0.03%]
全基因组SNP数据表明同域分布的北大西洋杀人鲸生态型具有复杂的祖先来源关系

Three ecotypes of killer whale occur in partial sympatry in the North Pacific. Individuals assortatively mate within the same ecotype, resulting in correlated ecological and genetic differentiation. A key question is whether this pattern of...
The sex locus is tightly linked to factors conferring sex-specific lethal effects in the mosquito Aedes aegypti [0.03%]
蚊子埃及伊蚊的性别决定基因座与赋予性别特异致死效应的因素紧密连锁

E Krzywinska et al.
In many taxa, sex chromosomes are heteromorphic and largely non-recombining. Evolutionary models predict that spread of recombination suppression on the Y chromosome is fueled by the accumulation of sexually antagonistic alleles in close li...
Origin of a cryptic lineage in a threatened reptile through isolation and historical hybridization [0.03%]

Identifying phylogenetically distinct lineages and understanding the evolutionary processes by which they have arisen are important goals of phylogeography. This information can also help define conservation units in endangered species. Suc...

We describe the astonishing changes and progress that have occurred in the field of population genetics over the past 50 years, slightly longer than the time since the first Population Genetics Group (PGG) meeting in January 1968. We review...
