Dispersal-Limited Symbionts Exhibit Unexpectedly Wide Variation in Host Specificity [0.03%]
扩散受限的内共生体表现出出乎意料的宿主特异性变异

Alix E Matthews et al.
A fundamental aspect of symbiotic relationships is host specificity, ranging from extreme specialists associated with only a single host species to generalists associated with many different species. Although symbionts with limited dispersa...

Accurate phylogenies are fundamental to our understanding of the pattern and process of evolution. Yet, phylogenies at deep evolutionary timescales, with correspondingly long branches, have been fraught with controversy resulting from confl...
Phylogenetic Analysis of Allotetraploid Species Using Polarized Genomic Sequences [0.03%]
基于极化基因组序列的异源四倍体物种系统发生分析

J Luis Leal et al.
Phylogenetic analysis of polyploid hybrid species has long posed a formidable challenge as it requires the ability to distinguish between alleles of different ancestral origins in order to disentangle their individual evolutionary history. ...
Impacts of Taxon-Sampling Schemes on Bayesian Tip Dating Under the Fossilized Birth-Death Process [0.03%]
取样方案对化石出生死亡过程贝叶斯定年法的影响

Arong Luo et al.
Evolutionary timescales can be inferred by molecular-clock analyses of genetic data and fossil evidence. Bayesian phylogenetic methods such as tip dating provide a powerful framework for inferring evolutionary timescales, but the most widel...
Diversification Models Conflate Likelihood and Prior, and Cannot be Compared Using Conventional Model-Comparison Tools [0.03%]
分化模型混淆了可能性和先验，不能使用常规的模型比较工具进行比较

Time-calibrated phylogenetic trees are a tremendously powerful tool for studying evolutionary, ecological, and epidemiological phenomena. Such trees are predominantly inferred in a Bayesian framework, with the phylogeny itself treated as a ...

The Lowest Radial Distance (LoRaD) method is a modification of the recently introduced Partition-Weighted Kernel method for estimating the marginal likelihood of a model, a quantity important for Bayesian model selection. For analyses invol...
Ancient Rapid Radiation Explains Most Conflicts Among Gene Trees and Well-Supported Phylogenomic Trees of Nostocalean Cyanobacteria [0.03%]
古老快速辐射解释了固氮蓝藻支序冲突及高支持度基因组树的主要分歧
Carlos J Pardo-De la Hoz,Nicolas Magain,Bryan Piatkowski et al.
Carlos J Pardo-De la Hoz et al.
Prokaryotic genomes are often considered to be mosaics of genes that do not necessarily share the same evolutionary history due to widespread horizontal gene transfers (HGTs). Consequently, representing evolutionary relationships of prokary...
Identifying the Best Approximating Model in Bayesian Phylogenetics: Bayes Factors, Cross-Validation or wAIC? [0.03%]
贝叶斯系统发生学中最佳近似模型的识别：贝叶斯因子、交叉验证还是wAIC？
Nicolas Lartillot
Nicolas Lartillot
There is still no consensus as to how to select models in Bayesian phylogenetics, and more generally in applied Bayesian statistics. Bayes factors are often presented as the method of choice, yet other approaches have been proposed, such as...
New Phylogenetic Markov Models for Inapplicable Morphological Characters [0.03%]
新的用于不适用形态特征的系统发育马尔可夫模型

Sergei Tarasov
This article proposes new Markov models for phylogenetic inference with anatomically dependent (inapplicable) morphological characters. The proposed models can explicitly model an anatomical dependency in which one or several characters are...
