The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

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 ...

Development of the nasal capsule in Emydura subglobosa (Testudines: Pleurodira) with a comparison to other turtles

The Anatomical Record, EarlyView.
Abstract Extant turtles occupy freshwater, marine, and terrestrial habitats, and their nasal region provides important evidence for the evolution of respiration‐ and sensory‐related cranial morphology. However, developmental data on the turtle nasal capsule remain limited, particularly in Pleurodira.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

A spatial risk map of gray wolf livestock depredations across the Great Lakes Region

Global Ecology and Conservation
Livestock depredations by gray wolves are a source of human-wildlife conflict across their recolonizing range in the midwestern United States of America (USA) which may hinder recovery efforts.

Osteohistological evidence for terrestrial adaptation and an extended growth period in mekosuchine crocodylians and its potential role in their extinction

The Anatomical Record, EarlyView.
Abstract The Australasian crocodylian fossil record is dominated by the extinct endemic clade Mekosuchinae, with known members spanning the Eocene‐to‐Holocene. This diverse clade exhibited high morphological disparity, from early members superficially similar to Crocodylus, to more terrestrial forms later in the clade's evolutionary history.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

A meta-analysis of edge effects on nesting success in forest and shrubland birds of eastern North America

Journal of Field Ornithology
Numerous studies report proximity to land cover edges decreases avian nesting success, yet variation among species, sites, and nesting guilds obscures overall patterns.
