Semicircular canal morphology in Rodentia and its relationship to locomotion

Journal of Anatomy, Volume 247, Issue 5, Page 953-969, November 2025.
Here, we present a selection of rodent inner ear 3D models in the lateral view, with rodents from seven locomotor categories (left to right: fossorial, semifossorial, semiaquatic, terrestrial, ricochetal, arboreal, and gliding). Semicircular canal (SCC) morphology, including radius of curvature and shape, can be differentiated between specialized forms

Sapsucker Wells as a Keystone Nutritional Resource: Evaluating Methods for Detection of Secondary Sap Consumers

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We used direct observations, camera traps, and environmental DNA (eDNA) to identify secondary consumers of sap from wells created by red‐naped (S. nuchalis) and Williamson's (S. thyroideus) sapsuckers among three groups of shrubs and trees in south‐central Colorado, USA.

Ecotone Might Provide Key Refugium for Sky Island Mammals in the Southern Appalachian Mountains

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Sky islands are among the most biodiverse ecosystems in the world but face a disproportionately high threat from climate change. We examined the spruce‐fir–northern hardwood ecotone as a possible refugium for mammals in the Southern Appalachian red spruce (Picea rubens)–Fraser fir (Abies fraseri) sky islands.
