Scaling of internal joint distance in the elbow of small‐ to medium‐sized mammals: Implications for range of motion analyses

open access: yesJournal of Anatomy, Volume 248, Issue 6, Page 950-971, June 2026.
We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.

Dehnel's Phenomenon in Mammals

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Some small mammals, which remain active year‐round, undergo reversible reductions in body size, braincase height, and the mass of internal organs, including the brain, from summer to winter. It is called Dehnel's phenomenon. In this review, we summarise knowledge of the mechanisms, adaptive value, and genetic basis of the phenomenon, and show how new ...

CSGM: A R Package to Conduct a Robust Cross‐Sectional Geometric Morphometric Analysis

open access: yesAmerican Journal of Biological Anthropology, Volume 190, Issue 1, May 2026.
ABSTRACT Objective Evaluating the relationships between the shape and biomechanical function of bone cross‐sections can contribute novel insights towards human functional and evolutionary morphology. However, this research involves unique analytical and statistical challenges when comparing complex and multidimensional shape data to multivariate ...

Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility?

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Since larger compound eyes and ocelli altogether improve vision, one may expect that insects specialised in chasing very mobile resources possess such morphological optimisation. By analysing 77 species of bees and wasps, we have found that wasps had larger eyes, but not larger ocelli, than bees.

Phenotypic Variation of Lake Charr (Salvelinus namaycush) in North America

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Lake charr (Salvelinus namaycush) head and body variation were compared among lakes across the species range in North America to determine if variation was organized more strongly among morphs or lakes. For 3445 lake charr, head‐shape variation was > 17 times greater among morphs than lakes and body‐shape variation was > 16 times greater among morphs ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...
