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.
Gene Flow Disruption and Population Declines in a Soil Arthropod in Fragmented Habitats [0.03%]
栖息地片段化导致土壤节肢动物基因流动受阻和种群数量减少

Tammy Ai Tian Ho et al.
Our results underscore that even seemingly abundant species in fragmented landscapes can experience severe reductions in effective population size and gene flow.
Population histories of the Indigenous Adivasi and Sinhalese from Sri Lanka using whole genomes [0.03%]
利用全基因组研究斯里兰卡土著亚迪瓦西人和僧伽罗人的人口历史
Jose A Urban Aragon,Esha Bandyopadhyay,Amali S Fernando et al.
Jose A Urban Aragon et al.
Additionally, in contrast to the Sinhalese, the Adivasi have maintained low effective population size and undergone strong founder events, which is consistent with their hunter-gatherer lifestyle, historic relocations, and habitat fragmentation.
Long read genome unravels MHC I genomic architecture, evolution, and diversity loss in Gubernatrix cristata [0.03%]
长读取基因组揭示了Gubernatrix cristata的MHC I基因组架构、进化和多样性丧失
Marisol Domínguez,Enrique Celemín,Nikolai Gusev et al.
Marisol Domínguez et al.
This genome reveals sustained high genome-wide heterozygosity despite inbreeding, with homozygosity patterns and effective population size estimates indicating a long-term decline.

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...
Hybrid genome assembly of the widespread bat Rhinolophus lepidus provides insights into susceptibility to SARS-CoV-2 infection and climate change threat [0.03%]
广泛分布的中华扁鼻蝠（Rhinolectus lepidus）混合基因组组装为SARS-CoV-2感染易感性和气候变化威胁提供见解
Kritika M Garg,Dolyce H W Low,Geraldine Lee et al.
Kritika M Garg et al.
We observed an effect of past climatic conditions on the effective population size with drastic population size reduction in the past 50,000 years.
Ancient genomes reveal demographic trajectories during the Classic Maya period [0.03%]
古基因组揭示了经典玛雅时期的种群动态轨迹
Madeleine Murray,Seiichi Nakamura,Melvin Fuentes et al.
Madeleine Murray et al.
Estimates of effective population size suggest a decline at the end of the Classic period, when Classic Maya civilization experienced widespread destabilization and collapse.
Pleistocene island connectivity did not enhance dispersal or impact population size change in Galápagos geckos [0.03%]
更新世岛屿间的连通性未增强加拉帕戈斯壁虎的扩散或影响种群大小的变化
Edward A Myers,Rayna C Bell,Isaac Overcast et al.
Edward A Myers et al.
Furthermore, we found no evidence of introgression; demographic modelling indicated that all species increased rapidly in effective population size in the period 20-150 ka, and these inferred demographic expansions were largely asynchronous and apparently unassociated with species or island age.
Were bed bugs the first urban pest insect? Genome-wide patterns of bed bug demography mirror global human expansion [0.03%]
基因组学揭示床虫种群扩张模式与人类活动紧密相关

, Cimex lectularius, belonging to two genetically distinct lineages, one associated with bats and the other with humans, coupled with demographic modelling, our findings suggests that while their association with humans dates back potentially hundreds of thousands of years, a dramatic change in the effective...population size of the human-associated lineage occurred approximately 13 000 years ago; a pattern not found in the bat-associated lineage.
Genetic Diversity Resonates With Conservation Strategies: A Case Study of Labeo rohita Population [0.03%]

Relatively lower effective population size estimation in both Padma and Jamuna could be a reflection of the loose conservation policy on these two rivers.
