The molecular clock hypothesis is fundamental in evolutionary biology as by assuming constancy of the molecular rate it provides a timeframe for evolution. However, increasing evidence shows time dependence of inferred molecular rates with ...
The Species versus Subspecies Conundrum: Quantitative Delimitation from Integrating Multiple Data Types within a Single Bayesian Approach in Hercules Beetles [0.03%]
种类与亚种的困境：在单一贝叶斯方法中整合多种数据类型以确定赫丘利金龟的量化界限

With the recent attention and focus on quantitative methods for species delimitation, an overlooked but equally important issue regards what has actually been delimited. This study investigates the apparent arbitrariness of some taxonomic d...

Phylogenetic trees are central to many areas of biology, ranging from population genetics and epidemiology to microbiology, ecology, and macroevolution. The ability to summarize properties of trees, compare different trees, and identify dis...

In modern evolutionary divergence analysis the role of geological information extends beyond providing a timescale, to informing molecular rate variation across the tree. Here I consider the implications of this development. I use fossil ca...
Maximum Likelihood Phylogenetic Inference is Consistent on Multiple Sequence Alignments, with or without Gaps [0.03%]
最大似然法系基因组系统发生分析在有无空位的多重序列对齐中是一致的

We prove that maximum likelihood phylogenetic inference is consistent on gapped multiple sequence alignments (MSAs) as long as substitution rates across each edge are greater than zero, under mild assumptions on the structure of the alignme...
Cryptic Species or Inadequate Taxonomy? Implementation of 2D Geometric Morphometrics Based on Integumental Organs as Landmarks for Delimitation and Description of Copepod Taxa [0.03%]
隐种还是分类不足？基于 integumental 器官作为地标的二维几何形态计量法在水溞类分类单元的划分和描述中的应用实施研究

Discovery of cryptic species using molecular tools has become common in many animal groups but it is rarely accompanied by morphological revision, creating ongoing problems in taxonomy and conservation. In copepods, cryptic species have bee...
Testing Classical Species Properties with Contemporary Data: How "Bad Species" in the Brassy Ringlets (Erebia tyndarus complex, Lepidoptera) Turned Good [0.03%]
用现代数据检验经典的类群属性——“差物种”在金环 Erebia tyndarus 类群中如何变好（Lepidoptera）

All species concepts are rooted in reproductive, and ultimately genealogical, relations. Genetic data are thus the most important source of information for species delimitation. Current ease of access to genomic data and recent computationa...
The Phylogeny of Rickettsia Using Different Evolutionary Signatures: How Tree-Like is Bacterial Evolution? [0.03%]
基于不同的进化特征的立克次氏体的系统发育研究：细菌进化的树状性如何？

Gemma G R Murray et al.
Rickettsia is a genus of intracellular bacteria whose hosts and transmission strategies are both impressively diverse, and this is reflected in a highly dynamic genome. Some previous studies have described the evolutionary history of Ricket...
Invariant Versus Classical Quartet Inference When Evolution is Heterogeneous Across Sites and Lineages [0.03%]
当各位点和谱系的进化是异质的时候，不变性的推理相对于经典四联法的推理

One reason why classical phylogenetic reconstruction methods fail to correctly infer the underlying topology is because they assume oversimplified models. In this article, we propose a quartet reconstruction method consistent with the most ...
