Genomic insights into runs of homozygosity, effective population size and selection signatures in Iranian meat and dairy sheep breeds [0.03%]
基因组视角下的伊朗肉羊和奶羊群体的纯合度区段、有效种群大小及选择痕迹分析

Genome-wide scan for run of homozygosity (ROH) stretches, effective population size (Ne) and selection signatures can help to elucidate mechanisms of selection and pinpoint genomic regions linked with phenotypic traits. This study aimed to ...

Effective population size (Ne) is a quantity of central importance in evolutionary biology and population genetics, but often notoriously challenging to estimate. Analyses of Ne are further complicated by the many interpretations of the con...

Variation in a sample of molecular sequence data informs about the past evolutionary history of the sample's population. Traditionally, Bayesian modelling coupled with the standard coalescent is used to infer the sample's bifurcating geneal...

This is a reference manual for the elegant, yet hideously complex concept of effective population size (Ne), inspired by a classic, self-published manual of automotive repair 'for the compleat idiot'. The Guide is timely, given the recent K...
Estimating effective population size trajectories from time-series identity-by-descent segments [0.03%]
从随时间变化的同一片断遗传关系中估计有效种群大小的变化轨迹

Long, identical haplotypes shared between pairs of individuals, known as identity-by-descent (IBD) segments, result from recently shared co-ancestry. Various methods have been developed to utilize IBD sharing for demographic inference in co...
ZW sex chromosome differentiation in paleognathous birds is associated with mitochondrial effective population size but not mitochondrial genome size or mutation rate [0.03%]
古鸟纲鸟类ZW性染色体分化与线粒体有效种群大小而非线粒体基因组大小或突变率有关

Eukaryotic genome size varies considerably, even among closely related species. The causes of this variation are unclear, but weak selection against supposedly costly "extra" genomic sequences has been central to the debate for over 50 year...
Spatio-Temporal Changes in Effective Population Size in an Expanding Metapopulation of Eurasian Otters [0.03%]

Conservation efforts are leading to demographic growth and spatial expansion of some previously endangered species. However, past population bottlenecks or population size fluctuations can have lasting effects on effective population size (...
Effects of Social Structure on Effective Population Size Change Estimates [0.03%]
社会结构对有效种群大小变化估计的影响

Most methods currently used to infer the "demographic history of species" interpret this expression as a history of population size changes. The detection, quantification, and dating of demographic changes often rely on the assumption that ...
Parallel genetic adaptation amid a background of changing effective population sizes in divergent yellow perch (Perca flavescens) populations [0.03%]
有效种群大小变化背景下黄鲈（Perca flavescens）不同种群的并行遗传适应性增强

Aquatic ecosystems are highly dynamic environments vulnerable to natural and anthropogenic disturbances. High-economic-value fisheries are one of many ecosystem services affected by these disturbances, and it is critical to accurately chara...
A reduction in effective population size has not relaxed purifying selection in the human population of Eivissa (Balearic Islands) [0.03%]
有效人口数量的减少并未放松对伊维萨岛（巴利阿里群岛）人类群体的纯化选择

Ibiza (Eivissa) is one of the main Balearic Islands in the western Mediterranean. Recent studies have highlighted the genetic distinctiveness of present-day Eivissans within the region and suggested it could be attributed to the genetic dri...
