Admixed genomes, particularly those with an evolutionary history of genetic exchange with an endangered or extinct species, are valued for innovative and unconventional conservation actions. Here, we show the substantial conservation value ...
Comprehensive cytogenetic analysis of the aardwolf (Proteles cristatus) and comparative chromosome painting with the domestic cat (Felis catus) [0.03%]
非洲毛猬狗（Proteles cristatus）的全面细胞遗传分析与家猫（Felis catus）的比较染色体绘图研究

Ellie Kolb et al.
Aardwolf (Proteles cristatus) is one of the four extant hyenas. Up to now, chromosome analysis of the aardwolf is limited to the knowledge that this insectivorous hyena shares the same 2n=40 diploid chromosome number with the three bone-cru...
Admixture and environment shape population genetic and phytochemical variation across a conifer hybrid zone (Juniperus, Cupressaceae) [0.03%]
杂交与环境塑造了分布在柏属（柏科）范围内的松柏类种群遗传和植物化学的变异情况

Kathryn A Uckele et al.
Ancestry variation in hybrid zones can reflect the causes and genetic basis of reproductive isolation and result in novel phenotypic variation with the potential for extended ecological effects. Junipers (Juniperus) are foundational tree sp...
Effective population size associated with sky-island distribution in the summit rat, Rattus baluensis, a mountain Bornean endemic [0.03%]
与天空岛屿分布相关的巴拉努斯山峰会鼠的有效人口规模

Miguel Camacho-Sanchez et al.
Tropical mountains are hotspots of biodiversity and they can harbor species with sky-island distributions on mountaintops. The summit rat, Rattus baluensis, is a Bornean endemic previously known from two populations in the Kinabalu range. H...

Estimators for the numbers of polymorphic loci or alleles, such as private allele counts or allelic richness, are not as commonly used or well developed for single nucleotide polymorphism (SNP) data as are genetic estimators which rely on d...

Understanding the processes that shape spatial genetic differentiation is essential for understanding how populations adapt to environmental change. By evaluating the influence of these processes, we can gain insights into evolutionary dyna...
Triploidy in a pair of hybridizing salamanders at the far end of the speciation continuum [0.03%]
一对杂交虎纹蝾螈的三倍体现象——在物种形成连续谱的另一端
Jan W Arntzen,Evan McCartney-Melstad,Spartak N Litvinchuk et al.
Jan W Arntzen et al.
Ecological and genetic interactions of species at the far end of the speciation continuum can often be studied in sympatry. Triturus cristatus (C) and T. marmoratus (M) are two deeply differentiated yet hybridizing salamander species that e...
'The genome assemblies of the Tui chub, Siphateles bicolor, and Arroyo Chub, Gila orcuttii' [0.03%]
"Tui Chub（Siphateles bicolor）和Arroyo Chub（Gila orcuttii）的基因组组装"

Natural history museum collections are invaluable repositories of biodiversity, offering insights into life on Earth. Genomic approaches provide powerful tools to characterize biodiversity in these collections. However using these collectio...
Retention of ancestral polymorphism, not recent introgression, best explains elevated levels of genetic variation in Gila Trout Oncorhynchus gilae [0.03%]
祖先多态性的保留而非近期杂交最能解释吉拉 trout(Oncorhynchus gilae)遗传变异的升高

Introgressive hybridization is widespread in nature, often between native and introduced species. Closely related species also share ancestral genetic variation that mimics introgressive hybridization. In this study, we employed reduced-rep...
