Nuevas icnitas de grandes mamíferos en el Mioceno de la Cuenca del Ebro (Huesca, España)

Geogaceta, 2023
El yacimiento de Los Ibones supone una nueva aportación al conocimiento del registro icnológico de vertebrados del Mioceno de la Cuenca del Ebro. El yacimiento se encuentra en la superficie de un nivel de calizas en el tránsito entre las formaciones ...

Unraveling differences in fecal microbiota stability in mammals: from high variable carnivores and consistently stable herbivores

Animal Microbiome, 2021
Background Through the rapid development in DNA sequencing methods and tools, microbiome studies on a various number of species were performed during the last decade. This advance makes it possible to analyze hundreds of samples from different species at

Convergence of Afrotherian and Laurasiatherian Ungulate-Like Mammals: First Morphological Evidence from the Paleocene of Morocco.

PLoS ONE, 2016
Molecular-based analyses showed that extant "ungulate" mammals are polyphyletic and belong to the two main clades Afrotheria (Paenungulata) and Laurasiatheria (Euungulata: Cetartiodactyla-Perissodactyla).

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition

Integrative 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.

Comparative functional morphological study of the tarsal joint mobility in artiodactyls and perissodactyls in light of astragalar morphological differences

Journal of Anatomy, Volume 249, Issue 3, Page 587-603, September 2026.
This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.

Species traits mediate the abundant‐center patterns in ground‐dwelling mammal and bird species in China

Ecography, Volume 2026, Issue 7, July 2026.
The abundance center hypothesis (ACH) posits that species abundance peaks at distribution centers; however, empirical support remains inconsistent. This study tested the generality of the ACH and investigated species traits as mediators of abundance–distance relationships.

Reconstruction of the cranial musculature of the paraceratheriid rhinocerotoid Pappaceras meiomenus and inferences of its feeding and chewing habits [PDF]

Acta Palaeontologica Polonica, 2017
The paraceratheriid Pappaceras is the earliest unequivocal rhinocerotoid genus to date, for which the osteological morphology is relatively unique compared to other perissodactyls.

Defaunation Maps for Tropical Mammals and Birds

Global Ecology and Biogeography, Volume 35, Issue 7, July 2026.
ABSTRACT Motivation Overhunting is a major driver of defaunation in tropical ecosystems, yet its impacts and spatial extent remain challenging to quantify through conventional remote sensing approaches. Novel modelling frameworks based on quantitative relationships between impacts on wildlife populations and the main drivers of hunting pressure have ...
