Performance of sheep and goats in a delay of gratification task
Animal CognitionSelf-control, the ability to resist an immediate reward for a more beneficial delayed outcome, is an adaptive skill underlying decision-making. While widely studied in non-human primates and birds, its evolution remains debated.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton
The Anatomical Record, EarlyView.Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Bite force estimates and morphological correlations of jaw muscles in parrots
The Anatomical Record, EarlyView.Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel
The Anatomical Record, EarlyView.Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...

Current Zoology, 2010 Although concerns about harvesting levels of the American Horseshoe Crab, Limulus polyphemus have prompted increased research into its ecology, current understanding of the species’ foraging ecology is mostly limited to mid-Atlantic populations.

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes
Animal Research and One Health, EarlyView.The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Using motion‐detection cameras to monitor foraging behaviour of individual butterflies
Ecology and EvolutionThe activity of many animals follows recurrent patterns and foraging is one of the most important processes in their daily activity. Determining movement in the search for resources and understanding temporal and spatial patterns in foraging has ...
