Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

The Anatomical Record, EarlyView.Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

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 ...

Travaux de l'Institut de Speologie Emile Racovitza, 2017 Oribatid mite species from Piatra Craiului Mountains (Southern Carpathians, Romania) were studied according to their altitudinal distribution. The mites were sampled from four sites (beech forest, fir and beech forest, nude scree and subalpine grassland)

Deciphering the Patterns and Drivers of Tardigrade Diversity Along Altitudinal Gradients
Molecular EcologyABSTRACT Altitudinal gradients offer a unique opportunity to understand the drivers of species richness, as mountain regions cover vast areas and contribute disproportionately to global terrestrial biodiversity. However, such gradients are often studied without considering the role of microhabitats, which introduce fine‐scale ...

Archaeological Prospection, EarlyView.ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...
