Maximize Resolution or Minimize Error? Using Genotyping-By-Sequencing to Investigate the Recent Diversification of Helianthemum (Cistaceae) [PDF]

open access: yes, 2019
A robust phylogenetic framework, in terms of extensive geographical and taxonomic sampling, well-resolved species relationships and high certainty of tree topologies and branch length estimations, is critical in the study of macroevolutionary patterns ...

OBAMA: OBAMA for Bayesian amino-acid model averaging [PDF]

open access: yesPeerJ, 2020
Background Bayesian analyses offer many benefits for phylogenetic, and have been popular for analysis of amino acid alignments. It is necessary to specify a substitution and site model for such analyses, and often an ad hoc, or likelihood based method is

A surrogate function for one-dimensional phylogenetic likelihoods

open access: yes, 2017
Phylogenetics has seen an steady increase in substitution model complexity, which requires increasing amounts of computational power to compute likelihoods.

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]

open access: yes, 2008
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using

Phylogenetic analyses of ray-finned fishes (Actinopterygii) using collagen type I protein sequences

open access: yesRoyal Society Open Science, 2021
Ray-finned fishes (Actinopterygii) are the largest and most diverse group of vertebrates, comprising over half of all living vertebrate species. Phylogenetic relationships between ray-finned fishes have historically pivoted on the study of morphology ...

Phylogeny and adaptive evolution of the brain-development gene microcephalin (MCPH1) in cetaceans. [PDF]

open access: yes, 2011
BACKGROUND: Representatives of Cetacea have the greatest absolute brain size among animals, and the largest relative brain size aside from humans. Despite this, genes implicated in the evolution of large brain size in primates have yet to be surveyed in ...

Bayesian total evidence dating reveals the recent crown radiation of penguins [PDF]

open access: yes, 2016
The total-evidence approach to divergence-time dating uses molecular and morphological data from extant and fossil species to infer phylogenetic relationships, species divergence times, and macroevolutionary parameters in a single coherent framework ...

Phylogeography by diffusion on a sphere: whole world phylogeography [PDF]

open access: yesPeerJ, 2016
Background Techniques for reconstructing geographical history along a phylogeny can answer many questions of interest about the geographical origins of species. Bayesian models based on the assumption that taxa move through a diffusion process have found

Out of the Black Sea: Phylogeography of the Invasive Killer Shrimp Dikerogammarus villosus across Europe [PDF]

open access: yes, 2015
The amphipod Dikerogammarus villosus has colonized most of the European main inland water bodies in less than 20 years, having deteriorating effect on the local benthic communities. Our aim was to reveal the species phylogeography in the native Black Sea
