Phylogenomics of a genus of 'Great Speciators' reveals rampant incomplete lineage sorting, gene flow, and mitochondrial discordance in island systems [0.03%]
一个“伟大特化物种”属的系统基因组学揭示了群岛系统的大量不完全谱系分选、基因流和线粒体分歧

Jenna M McCullough et al.
The flora and fauna of island systems-especially those in the Indo-Pacific-are renowned for their exceptional diversification and for shaping key evolutionary theories. Yet, phylogenetic studies often undersample the full diversity of these...

A somewhat personal account of the development and acceptance of numerical taxonomic methods during the early years of the journal Systematic Zoology. Includes a few perspectives on the changes in taxonomy and the journal after 75 years. ...
Algebraic Invariants for Inferring 4-leaf Semi-Directed Phylogenetic Networks [0.03%]
用于推断四叶半有向进化网络的代数不变量

Samuel Martin et al.
A core goal of phylogenomics is to determine the evolutionary history of a set of species from biological sequence data. Phylogenetic networks are able to describe more complex evolutionary phenomena than phylogenetic trees but are more dif...
Cryptic species can be phylogenetically old despite strong sex-biased dispersal [0.03%]
隐藏物种的系统发育年龄可以很大，尽管雄性偏向扩散很强烈
Lars Dietz,Jonas Eberle,Sandra Kukowka et al.
Lars Dietz et al.
The impact of strongly differentiated populations on species delimitation due to limited or sex-biased dispersal remains challenging and under-explored in the framework of integrative taxonomy. The Mediterranean chafer beetle genus Pachypus...
DupLoss-2: Improved Phylogenomic Species Tree Inference under Gene Duplication and Loss [0.03%]

Accurate species tree reconstruction in the presence of widespread gene duplication and loss is a challenging problem in eukaryote phylogenomics. Many phylogenomics methods have been developed over the years to address this challenge; these...
The Complex Interplay between Evolutionary Flexibility and Diversification in a Family of Spiders [0.03%]
蜘蛛进化适应性与多样化的复杂关系研究——以寇蛛科为例

Guanliang Meng et al.
Understanding the mechanisms of how morphological traits drive speciation and contribute to species richness is pivotal in evolutionary biology. In this context, the evolutionary flexibility of morphological traits may play a significant ro...
Nuclear Phylogenomic Insights into Relationships, Support, and Conflict Among the Early Diverging Lineages of the Megadiverse Epidendroid Orchids [0.03%]
核基因组系统发育研究揭示了千屈兰兰亚科早期分化类群之间的关系、支持和冲突
Craig F Barrett,John V Freudenstein,Samuel V Skibicki et al.
Craig F Barrett et al.
Parasites present fascinating examples of evolutionary modification that simultaneously pose challenges for systematics. This is exemplified by fully mycoheterotrophic orchids, which are completely dependent on fungi, constituting nearly ha...
No Consistent Effect of Migration on Speciation Rates in Two Avian Superfamilies: A Check on the Robustness of Trait-Dependent Diversification Methods [0.03%]
迁移对两类鸟类超科分化率无影响：检验性状相关分化的稳健性的研究
Gina M Calabrese,Kira E Delmore,Jochen B W Wolf et al.
Gina M Calabrese et al.
Seasonal migration is performed by taxonomically diverse groups across the planet's oceans and continents. Migration has been hypothesized to promote speciation through a variety of mechanisms that may initiate reproductive isolation and po...
Introgressed variants obscure phylogenetic relationships but are not subject to positive selection in Australasian long-tailed parrots [0.03%]
异域基因渗入扰乱了分类单元关系但不会导致选择效应

Brian Tilston Smith et al.
Gene flow often obscures phylogenetic relationships but the evolutionary significance of introgressed variants is unclear. Here we examine the Australasian long-tailed parrots (Psittaculinae: Polytelini) in which an unexpected sister relati...
