Phylogenomics, Biogeography, and Morphometrics Reveal Rapid Phenotypic Evolution in Pythons After Crossing Wallace's Line [0.03%]
系统发育基因组学、生物地理学和形态计量学揭示了穿越沃氏线后蟒科动物的快速表型演化

Damien Esquerré et al.
Ecological opportunities can be provided to organisms that cross stringent biogeographic barriers towards environments with new ecological niches. Wallace's and Lyddeker's lines are arguably the most famous biogeographic barriers, separatin...
On the Selection and Analysis of Clades in Comparative Evolutionary Studies [0.03%]
论比较进化研究中支系的选择与分析
Steven Poe,Christopher Anderson,Joseph Barnett
Steven Poe
Researchers commonly present results of comparative studies of taxonomic groups. In this review, we criticize the focus on named clades, usually, comparably ranked groups such as families or orders, for comparative evolutionary analyses and...
Evaluating the Performance of Probabilistic Algorithms for Phylogenetic Analysis of Big Morphological Datasets: A Simulation Study [0.03%]
基于形态大数据的系统发育分析的概率算法性能评估：一项模拟研究

Reconstructing the tree of life is an essential task in evolutionary biology. It demands accurate phylogenetic inference for both extant and extinct organisms, the latter being almost entirely dependent on morphological data. While parsimon...
Exact Distribution of Divergence Times from Fossil Ages and Tree Topologies [0.03%]
来自化石年龄和树形的分歧时间的确切分布
Gilles Didier,Michel Laurin
Gilles Didier
Being given a phylogenetic tree of both extant and extinct taxa in which the fossil ages are the only temporal information (namely, in which divergence times are considered unknown), we provide a method to compute the exact probability dist...
Bayesian Inference of Ancestral Host-Parasite Interactions under a Phylogenetic Model of Host Repertoire Evolution [0.03%]
基于宿主谱系模型的寄生虫祖先宿主交互的贝叶斯推断方法研究
Mariana P Braga,Michael J Landis,Sören Nylin et al.
Mariana P Braga et al.
Intimate ecological interactions, such as those between parasites and their hosts, may persist over long time spans, coupling the evolutionary histories of the lineages involved. Most methods that reconstruct the coevolutionary history of s...
Global Diversification of Anelosimus Spiders Driven by Long-Distance Overwater Dispersal and Neogene Climate Oscillations [0.03%]
安洛西蚊蛛属全球多样化由远距跨水扩散和新近纪气候振荡驱动而成
Yufa Luo,Seok P Goh,Daiqin Li et al.
Yufa Luo et al.
Vicariance and dispersal events, combined with intricate global climatic history, have left an imprint on the spatiotemporal distribution and diversity of many organisms. Anelosimus cobweb spiders (Theridiidae), are organisms ranging in beh...
Lineage Identification Affects Estimates of Evolutionary Mode in Marine Snails [0.03%]
谱系识别影响海洋螺类进化方式的估算
Felix Vaux,Michael R Gemmell,Simon F K Hills et al.
Felix Vaux et al.
In order to study evolutionary pattern and process, we need to be able to accurately identify species and the evolutionary lineages from which they are derived. Determining the concordance between genetic and morphological variation of livi...
A Multitype Birth-Death Model for Bayesian Inference of Lineage-Specific Birth and Death Rates [0.03%]
用于系谱特异性出生率和死亡率贝叶斯推断的多类型生灭模型
Joëlle Barido-Sottani,Timothy G Vaughan,Tanja Stadler
Joëlle Barido-Sottani
Heterogeneous populations can lead to important differences in birth and death rates across a phylogeny. Taking this heterogeneity into account is necessary to obtain accurate estimates of the underlying population dynamics. We present a ne...

Birds can use different types of gaits to move on the ground: they either walk, hop, or run. Although velocity can easily explain a preference for running, it remains unclear what drives a bird species to favor hopping over walking. As many...
Morphological Phylogenetics Evaluated Using Novel Evolutionary Simulations [0.03%]
采用新型进化模拟评估形态系统发生学
Joseph N Keating,Robert S Sansom,Mark D Sutton et al.
Joseph N Keating et al.
Evolutionary inferences require reliable phylogenies. Morphological data have traditionally been analyzed using maximum parsimony, but recent simulation studies have suggested that Bayesian analyses yield more accurate trees. This debate is...
