The carnivore remains from the Sima de los Huesos Middle Pleistocene site(Sierra de Atapuerca, Spain) [PDF]

open access: yes, 1997
Remains of carnivores from the Sima de los Huesos site representing at least 158 adult individuals of a primitive (i.e., not very speleoid) form of Ursus deningeri Von Reichenau 1906, have been recovered through the 1995 field season.

Geographic distributions shape the functional traits in a large mammalian family

open access: yesEcology and Evolution, 2021
Traits of organisms are shaped by their living environments and also determined in part by their phylogenetic relationships. For example, phylogenetic relationships often affect the geographic distributions of animals and cause variation in their living ...

Nuevo registro del oso andino (Tremarctos ornatus, Carnivora: Ursidae) para el departamento de Caldas, Colombia

open access: yesMammalogy Notes, 2023
En Colombia la fragmentación de ecosistemas naturales, las actividades agrícolas y ganaderas han generado perdida en el hábitat natural del oso andino (Tremarctos ornatus), por lo cual, sus registros no son frecuentes.  Aquí reportamos un nuevo registro

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

The accelerating influence of humans on mammalian macroecological patterns over the late Quaternary [PDF]

open access: yes, 2019
The transition of hominins to a largely meat-based diet ~1.8 million years ago led to the exploitation of other mammals for food and resources. As hominins, particularly archaic and modern humans, became increasingly abundant and dispersed across the ...

Expanding the Faunal Interpretation of the Cova Eirós (NW Iberia) Middle Paleolithic–Early Upper Paleolithic Record With ZooMS

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The Cova Eirós archaeopaleontological site preserves the most comprehensive archaeostratigraphic sequence in the northwestern Iberian Peninsula, with an exceptionally rich record spanning from the Mousterian to the Upper Paleolithic. The extensive fragmentation of the faunal record and the rich taxonomic diversity at this site have limited the

Comparative Analysis of Olfactory Receptor Repertoires Sheds Light on the Diet Adaptation of the Bamboo-Eating Giant Panda Based on the Chromosome-Level Genome

open access: yesAnimals, 2023
The giant panda (Ailuropoda melanoleuca) is the epitome of a flagship species for wildlife conservation and also an ideal model of adaptive evolution. As an obligate bamboo feeder, the giant panda relies on the olfaction for food recognition.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Bite‐DNA Shows Substantial Browsing on Willows (Salix spp.) by North American Bison in Yellowstone National Park

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Riparian willows in Yellowstone National Park are shaped by ungulate browsing, but species‐specific contributions remain unclear. Using bite‐DNA metabarcoding of browsed willow twigs across six northern range sites, we found that American bison were the most frequent browsers, exceeding elk and often mule deer.

The influence of skull shape modularity on internal skull structures: a 3D-Pilot study using bears [PDF]

open access: yes, 2015
In order to capture the phenotypic variation of the internal skull structures, such as the sinuses or the brain, it is necessary to perform CT scans in a large number of specimens, which is difficult and expensive.
