Influence of Food Distribution and Relatedness on Social Interactions in a Colony of Free‐Ranging Domestic Cats (Felis catus)

open access: yesEthology, Volume 131, Issue 7, July 2025.
In a free‐ranging colony of domestic cats, individuals engaged in affiliative but not agonistic behaviors in a selective manner. The distribution of food resources but not relatedness influenced affiliative interactions between dyads of cats. When food was provided at feeding stations, there was a similar distribution of affiliative interactions among ...

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 ...

A steric gate prevents mutagenic dATP incorporation opposite 8‐oxo‐deoxyguanosine in mitochondrial DNA polymerases

open access: yesThe FEBS Journal, Volume 292, Issue 13, Page 3430-3448, July 2025.
Reactive oxygen species induce mutagenic DNA lesions, such as 8‐oxo‐2′‐deoxyguanosine (8‐oxodG), which acts as a template for dCMP and dAMP incorporation through its anti and syn conformations. Specific residues must regulate the fidelity of templated 8‐oxodG.

Immunological Responses to Tetanus and Influenza Vaccination in Donkeys

open access: yesJournal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Donkeys are routinely vaccinated with protocols developed for horses, yet species‐specific data on their immune responses are limited. Hypothesis/Objectives We hypothesized that donkeys exhibit robust T‐cell‐mediated immunity and regulatory adaptation after vaccination, comparable to horses.

Written in bones: palaeoclimate histotaphonomic history inferred from a complete Megatherium skeleton preserved in the Atacama Desert

open access: yesPalaeontology, Volume 68, Issue 4, July/August 2025.
Abstract A nearly complete and relatively well‐preserved skeleton of the giant ground sloth Megatherium sp. in the hyperarid core of the Atacama Desert reveals how climate related taphonomic processes drastically transformed these remains over time.
