Genetic diversity is an important driver affecting the health of wildlife populations. In cooperatively breeding species, human impacts and breeder turnover can affect genetic diversity in groups. We generally do not have strong inferences ...
Facultative polyandry under heat stress and the evolutionary potential for climate-driven shifts in mating systems [0.03%]

The ecology of mating interactions determines a species' mating system, yet whether environmental change can alter the mating system of a species remains unclear. Elevated temperatures can cause male sterility, prompting females to remate f...
No evidence for heritability of extra-pair mating behavior in a cooperatively breeding bird [0.03%]

While extra-pair mating prevails among socially monogamous birds, it does not occur in all individuals within a population. Then, what underlies this variability? A poorly explored mechanism is the genetic contribution to the behavioral tra...
Lineage-specific targets of positive selection in three leaf beetles correspond with defence capacity against their shared parasitoid wasp [0.03%]
三种叶甲科昆虫的谱系特异性正选择目标与其对共享寄生黄蜂的防御能力对应关系研究
Xuyue Yang,Kalle Tunström,Tanja Slotte et al.
Xuyue Yang et al.
Parasitoid wasps are major causes of mortality of many species, making host immune defences a common target of adaptive evolution, though such targets outside model species are poorly understood. In this study, we used two tests of positive...
Genomic analysis of differentiation and demography of the formerly conspecific agile (Dipodomys agilis) and Dulzura (D. simulans) kangaroo rats [0.03%]
基因组分析揭示过去同种的灵活鼠和杜尔祖拉鼠豚分化及群体历史事件

Karyotype variation within Pacific kangaroo rat Dipodomys agilis motivated its division in 1997 into the agile kangaroo rat (AKR, D. agilis, 2N = 62) in the north of its range in California, and Dulzura kangaroo rat (DKR, D. simulans, 2N = ...

Repetitive DNA sequences are ubiquitous in eukaryotic genomes, significantly influencing their structure, function, and evolution. They can facilitate genomic rearrangements, contributing to chromosomal and genomic diversity. Chrysomelidae ...
Genome sequence analysis provides evidence that a boreal crustacean colonised Svalbard well before the ongoing Atlantification of the Arctic [0.03%]
基因组序列分析提供了证据表明，在北极当前大西洋化之前一个北欧的甲壳类动物就殖民了斯瓦尔巴群岛
Hedvig Kriszta Csapó,Jan Marcin Weslawski,Nova Mieszkowska et al.
Hedvig Kriszta Csapó et al.
The study of present-day species distributions often raises questions about historical demography. A particularly interesting phenomenon to put in historical context is contemporary human-induced atlantification and its role in reshaping Ar...
Quantifying genetic and genotypic gain gaps in Eucalyptus: the hidden cost of ignoring inbreeding and dominance [0.03%]
量化遗传和基因型收益差距在尤加利树中的隐藏成本：忽略近交和显性带来的影响
