Testing the Relationships between Diversification, Species Richness, and Trait Evolution [0.03%]
检验多样化、物种丰富度和性状进化之间的关系

Understanding which traits drive species diversification is essential for macroevolutionary studies and to understand patterns of species richness among clades. An important tool for testing if traits influence diversification is to estimat...
How Well Can We Detect Lineage-Specific Diversification-Rate Shifts? A Simulation Study of Sequential AIC Methods [0.03%]
顺序AIC方法检测谱系特异性分化速率变化的能力如何？一项模拟研究

Michael R May
Evolutionary biologists have long been fascinated by the extreme differences in species numbers across branches of the Tree of Life. This has motivated the development of statistical methods for detecting shifts in the rate of lineage diver...
Detecting Hidden Diversification Shifts in Models of Trait-Dependent Speciation and Extinction [0.03%]
隐性多样化转移的检测：基于性状依赖的物种分化与灭绝模型中的研究

The distribution of diversity can vary considerably from clade to clade. Attempts to understand these patterns often employ state-dependent speciation and extinction models to determine whether the evolution of a particular novel trait has ...

Nico M Franz et al.
Classifications and phylogenies of perceived natural entities change in the light of new evidence. Taxonomic changes, translated into Code-compliant names, frequently lead to name:meaning dissociations across succeeding treatments. Classifi...
Does Gene Tree Discordance Explain the Mismatch between Macroevolutionary Models and Empirical Patterns of Tree Shape and Branching Times? [0.03%]
基因树分歧能否解释宏观进化模型与树木形态和分支时间实证模式之间的不匹配现象？
Tanja Stadler,James H Degnan,Noah A Rosenberg
Tanja Stadler
Classic null models for speciation and extinction give rise to phylogenies that differ in distribution from empirical phylogenies. In particular, empirical phylogenies are less balanced and have branching times closer to the root compared t...
Estimating the Effect of Competition on Trait Evolution Using Maximum Likelihood Inference [0.03%]
利用最大似然估计法估算竞争对性状演化的影响
Jonathan Drury,Julien Clavel,Marc Manceau et al.
Jonathan Drury et al.
Many classical ecological and evolutionary theoretical frameworks posit that competition between species is an important selective force. For example, in adaptive radiations, resource competition between evolving lineages plays a role in dr...
Gene Tree Discordance Causes Apparent Substitution Rate Variation [0.03%]
基因树不一致引起 substitution rate 变化现象
Fábio K Mendes,Matthew W Hahn
Fábio K Mendes
Substitution rates are known to be variable among genes, chromosomes, species, and lineages due to multifarious biological processes. Here, we consider another source of substitution rate variation due to a technical bias associated with ge...
Bridging Inter- and Intraspecific Trait Evolution with a Hierarchical Bayesian Approach [0.03%]
用分层贝叶斯方法连接动植物个体间和个体内性状演化
Anna Kostikova,Daniele Silvestro,Peter B Pearman et al.
Anna Kostikova et al.
The evolution of organisms is crucially dependent on the evolution of intraspecific variation. Its interactions with selective agents in the biotic and abiotic environments underlie many processes, such as intraspecific competition, resourc...
Integrative Taxonomy Recognizes Evolutionary Units Despite Widespread Mitonuclear Discordance: Evidence from a Rotifer Cryptic Species Complex [0.03%]
综合分类学承认尽管线粒体和细胞核基因存在分歧，但仍能识别进化单位——来自一种轮虫隐存物种复合群的证据
Spiros Papakostas,Evangelia Michaloudi,Konstantinos Proios et al.
Spiros Papakostas et al.
Mitonuclear discordance across taxa is increasingly recognized as posing a major challenge to species delimitation based on DNA sequence data. Integrative taxonomy has been proposed as a promising framework to help address this problem. How...
Distinct Processes Drive Diversification in Different Clades of Gesneriaceae [0.03%]
导致苦苣苔科不同分支植物多样化发展的进化机制不同

Eric H Roalson
Using a time-calibrated phylogenetic hypothesis including 768 Gesneriaceae species (out of [Formula: see text]3300 species) and more than 29,000 aligned bases from 26 gene regions, we test Gesneriaceae for diversification rate shifts and th...
