A Consistent Estimator of the Evolutionary Rate [PDF]

open access: yes, 2014
We consider a branching particle system where particles reproduce according to the pure birth Yule process with the birth rate L, conditioned on the observed number of particles to be equal n.

Morphological modularity in the vertebral column of Felidae (Mammalia, Carnivora)

open access: yesBMC Evolutionary Biology, 2017
BackgroundPrevious studies have demonstrated that the clear morphological differences among vertebrae across the presacral column are accompanied by heterogeneous functional signals in vertebral shape.

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition

open access: yesIntegrative Zoology, EarlyView.
Herbivores showed higher alpha diversity than carnivores/omnivores, while omnivores had the highest beta diversity. Host phylogeny influenced gut microbiota more strongly in herbivores/omnivores, with phylogenetic distance correlating to microbiota dissimilarity.

The influence of modularity on cranial morphological disparity in Carnivora and Primates (Mammalia). [PDF]

open access: yesPLoS ONE, 2010
Although variation provides the raw material for natural selection and evolution, few empirical data exist about the factors controlling morphological variation.

Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Use of a Sendai virus-based vector for effcient transduction of pinniped fbroblasts

open access: yesВавиловский журнал генетики и селекции, 2019
Generation of induced pluripotent stem (iPS) cells expanded possibilities of pluripotency and early development studies. Generation of order Carnivora iPS cells from dog (Canis lupus familiaris), snow leopard (Panthera uncia), and American mink (Neovison

The Earliest Ursine Bear Demonstrates the Origin of Plant-Dominated Omnivory in Carnivora

open access: yesiScience, 2020
Summary: In Carnivora, increases in body size often lead to dietary specialization toward hypercarnivory. Ursine bears (Tremarctos and Ursus), however, are the only omnivorous Carnivora that evolved large body sizes (i.e., >50 kg). Traits contributing to

Morphology of Guard Hairs in Amazonian Marsupials: Intergeneric Variation, Habitat and Habit Association in a Phylogenetic Framework of the Order Didelphimorphia

open access: yesActa Zoologica, EarlyView.
ABSTRACT The cuticle and medulla of guard hairs exhibit distinct morphological patterns among mammalian species. To investigate this variability in marsupials from the Brazilian Amazon, we analysed guard hairs from nine Didelphimorphia species and incorporated data from an additional 25 didelphid species.

New Material and Revision of the Carnivora, Mammalia from the Lower Pleistocene Locality Apollonia 1, Greece

open access: yes, 2018
During the last field campaigns in the mammal fossiliferous site Apollonia 1 (Macedonia, Greece), new carnivoran material has been discovered. The new collection added two new carnivoran taxa, Homotherium latidens and Panthera gombaszogensis.
