Data-specific substitution models improve protein-based phylogenetics.

Publication Type: Academic Journal

Source(s): PeerJ. Aug2023, p1-20. 20p.

Abstract: Calculating amino-acid substitution models that are specific for individual protein data sets is often difficult due to the computational burden of estimating large numbers of rate parameters. In this study, we tested the computational efficiency and a...

Determining Phylogenetic Relationships of Some Endemic and Rare Astragalus Taxa in the Van Lake Basin.

Publication Type: Academic Journal

Source(s): Journal of Agriculture & Nature / Kahramanmaraş Sütçü İmam Üniversitesi Tarım & Doğa Dergisi. 2023, Vol. 26 Issue 4, p806-814. 9p.

Abstract: Dünyanın en çeşitli cinsi olan Astragalus, yaklaşık 3000 farklı takson içermektedir. Bu cins Türkiye'de 489 takson ve 63 bölüme sahiptir ve bu da ona %51 endemizm oranı vermektedir. Bu araştırma için 2019 yılında Van Gölü Havzası'ndan 82 Astragalus tak...

Determinants and Assembly Mechanism of Bacterial Community Structure in Ningxia Section of the Yellow River.

Publication Type: Academic Journal

Source(s): Microorganisms. Feb2023, Vol. 11 Issue 2, p496. 19p.

Abstract: The Yellow River is a valuable resource in the Ningxia Hui Autonomous Region and plays a vital role in local human activities and biodiversity. Bacteria are a crucial component of river ecosystems, but the driving factors and assembly mechanisms of bac...

Clustering systems of phylogenetic networks.

Publication Type: Academic Journal

Source(s): Theory in Biosciences. Nov2023, Vol. 142 Issue 4, p301-358. 58p.

Abstract: Rooted acyclic graphs appear naturally when the phylogenetic relationship of a set X of taxa involves not only speciations but also recombination, horizontal transfer, or hybridization that cannot be captured by trees. A variety of classes of such netw...

Phylogenetically conservative trait correlation: Quantification and interpretation.

Publication Type: Academic Journal

Source(s): Journal of Ecology. Oct2023, Vol. 111 Issue 10, p2105-2117. 13p.

Abstract: Correlation across species between two quantitative traits, or between a trait and a habitat property, can suggest that a trait value is effective in sustaining populations in some contexts but not others. It is widely held that such correlations shoul...

Total evidence time-scaled phylogenetic and biogeographic models for the evolution of sea cows (Sirenia, Afrotheria).

Publication Type: Academic Journal

Source(s): PeerJ. Aug2022, p1-52. 52p.

Abstract: Molecular phylogenetic studies that have included sirenians from the genera Trichechus, Dugong, and Hydrodamalis have resolved their interrelationships but have yielded divergence age estimates that are problematically discordant. The ages of these lin...

Estimating bite force in extinct dinosaurs using phylogenetically predicted physiological cross-sectional areas of jaw adductor muscles.

Publication Type: Academic Journal

Source(s): PeerJ. Jul2022, p1-19. 19p.


Abstract: I present a Bayesian phylogenetic predictive modelling (PPM) framework that allows the prediction of muscle parameters (physiological cross-sectional area, APhys) in extinct archosaurs from skull width (WSk) and phylogeny. This approach is robust to ph...

The ClaDS rate-heterogeneous birth–death prior for full phylogenetic inference in BEAST2.

Publication Type: Academic Journal

Source(s): Systematic Biology. Sep2023, Vol. 72 Issue 5, p1180-1187. 8p.

Abstract: Bayesian phylogenetic inference requires a tree prior, which models the underlying diversification process that gives rise to the phylogeny. Existing birth–death diversification models include a wide range of features, for instance, lineage-specific va...

Synthesizing the phylogenetic evidence for mutualism-associated diversification.

Publication Type: Academic Journal

Source(s): Evolution. Aug2023, Vol. 77 Issue 8, p1882-1892. 11p.

Abstract: Mutualisms are associations in which interacting species provide services or resources to each other. It has been suggested that being party to a mutualism can spur the diversification of the interacting species due to several potential hypothesized me...

A topology-marginal composite likelihood via a generalized phylogenetic pruning algorithm.

Publication Type: Academic Journal

Source(s): Algorithms for Molecular Biology. 7/31/2023, Vol. 18 Issue 1, p1-18. 18p.

Abstract: Bayesian phylogenetics is a computationally challenging inferential problem. Classical methods are based on random-walk Markov chain Monte Carlo (MCMC), where random proposals are made on the tree parameter and the continuous parameters simultaneously....
