Cosmovision as Cognitive Technology: The Case of Mesoamerican Medicinal Knowledge

open access: yesTopics in Cognitive Science, EarlyView.
Abstract We examine the use of cognitive technologies in the acquisition and retention of botanical and medicinal knowledge. We focus on the Cruz‐Badianus codex, a 16th‐century Nahua (Aztec) herbarium which discusses the use of plants for a range of illnesses.

The Earliest Ursine Bear Demonstrates the Origin of Plant-Dominated Omnivory in Carnivora

open access: yesiScience, 2020
Summary: In Carnivora, increases in body size often lead to dietary specialization toward hypercarnivory. Ursine bears (Tremarctos and Ursus), however, are the only omnivorous Carnivora that evolved large body sizes (i.e., >50 kg). Traits contributing to

Phylogenetic allometric scaling of near basal breathing frequency in terrestrial, semi‐aquatic and aquatic mammals

open access: yesExperimental Physiology, EarlyView.
Abstract We measured the BASAL breathing frequency following an overnight fast in adult, non‐pregnant/non‐lactating, inactive mammals ranging in body mass from 15 to 5520 kg. The data included results from 338 individual animals from 34 species that were divided into terrestrial, semi‐aquatic (Otariidae and Phocidae) and aquatic mammals.

Cardiac conduction system and the electrocardiogram of the common hippopotamus (Hippopotamus amphibius)

open access: yesExperimental Physiology, EarlyView.
Abstract The common hippopotamus (Hippopotamus amphibius) shares a common terrestrial ancestor with whales (Cetacea) and has independently evolved similar physiological adaptations to their aquatic lifestyle. Although several studies have explored the electrical signalling in whale hearts, the understanding of the conduction system and electrical ...

Covariation in the Craniocervical Junction of Carnivora

open access: yesJournal of Morphology
ABSTRACTThe craniocervical junction is the transition between the skull and the vertebral column that provides mobility while maintaining sufficient stability (i.e., protection of the brainstem and the spinal cord). The key elements involved are the occiput, the first cervical vertebra (CV1, atlas) and the second cervical vertebra (CV2, axis).

Describing Diet of Imperiled Sierra Nevada Red Foxes and a Carnivoran Competitor Using DNA Metabarcoding

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Montane red foxes (Vulpes vulpes ssp.) native to western North America are of broad conservation interest, but their ecology is poorly understood due to their rarity. We examined the diet of the Sierra Nevada red fox (V. v. necator) in an unstudied portion of their range in Oregon, USA, then evaluated dietary overlap between red fox and coyote (Canis ...

Modelling Species Distribution at the Boundaries of the Earth's Climate

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 7, July 2025.
ABSTRACT Aim Correlative species distribution models (SDMs) are widely used to project species' responses to global changes. The climatic niche of a species is calibrated under current climate conditions and then projected in space and/or time, making model extrapolation an important concern. This issue is particularly relevant when considering species
