The recent rapid radiation of Tillandsia subgenus Tillandsia (Bromeliaceae) provides an attractive system to study the drivers and constraints of species diversification. This species-rich Neotropical monocot clade includes predominantly ep...

DNA analyses have revolutionized species identification and taxonomic work. Yet, persistent challenges arise from little differentiation among and considerable variation within species, particularly among closely related groups. While image...
Link between the Birth-Death process and the Kingman Coalescent - Applications to Phylogenetic Epidemiology [0.03%]
birth-death过程与Kingman coalescent之间的关系及其在系谱流行病学中的应用

The two most popular tree models used in phylogenetics are the birth-death process (BD) and the Kingman coalescent (KC). These two models differ in several respects, notably: (i) the curve of the population size through time is a stochastic...
Accelerating Maximum Likelihood Phylogenetic Inference via Early Stopping to Evade (Over-)optimization [0.03%]
通过提前停止以避免过度优化来加速最大似然法的系统发育推断

Maximum Likelihood (ML) based phylogenetic inference constitutes a challenging optimization problem. Given a set of aligned input sequences, phylogenetic inference tools strive to determine the tree topology, the branch-lengths, and the evo...
Phylogenetic Estimation of Branch-specific Shifts in the Tempo of Origination [0.03%]

Studying rates of species diversification is one of the key themes in macroevolution. In particular, we are interested in if some clades in a phylogeny diversify more rapidly/slowly than others due to branch-specific diversification rates. ...
Inference of Cross-Species Gene Flow Using Genomic Data Depends on the Methods: Case Study of Gene Flow in Drosophila [0.03%]
基于基因组数据的跨物种基因流推断依赖于方法:果蝇中基因流情况的研究案例

Analysis of genomic data in the past two decades has highlighted the prevalence of introgression as an important evolutionary force in both plants and animals. The genus Drosophila has received much attention recently, with an analysis of g...
Type genomics: a Framework for integrating Genomic Data into Biodiversity and Taxonomic research [0.03%]

Name-bearing type specimens have a fundamental role in characterising biodiversity, as these objects represent the physical link between a scientific name and the biological organism. Type specimens are usually deposited in natural history ...
Batesian Mimicry Converges Towards Inaccuracy in Myrmecomorphic Spiders [0.03%]
拟态蚂蚁的 spiders 的 Batesian 拟态趋于不准确收敛

Batesian mimicry is an impressive example of convergent evolution driven by predation. However, the observation that many mimics only superficially resemble their models despite strong selective pressures is an apparent paradox. Here, we te...

Models used in likelihood-based morphological phylogenetics often adapt molecular phylogenetics models to the specificities of morphological data. Such is the case for the widely used Mkv model-which introduces an acquisition bias correctio...

Phylogenies contain a wealth of information about the evolutionary history and process that gave rise to the diversity of life. This information can be extracted by fitting phylogenetic models to trees. However, many realistic phylogenetic ...
