From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy
The Anatomical Record, EarlyView.Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

The effect of feeding on the respiratory activity of the sloth
Brazilian Journal of Medical and Biological Research, 2002 The aim of the present study was to confirm whether feeding influences the resting breathing rate and to observe possible alterations in blood gas and pH levels produced by feeding in unanesthetized sloths (Bradypus variegatus). Five adult male sloths (4.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
The Anatomical Record, EarlyView.Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

What are the vector species of the Oropouche virus?
Pest Management Science, EarlyView.Here, we review the timeline of Oropouche virus (OROV) detection in various hematophagous Diptera, from 1955 to date, including mosquitoes and midges. All vector competence experiments also are described. The results suggest that Culicoides are the primary vectors.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant defence phenotypes commonly integrate physical and chemical traits that may act synergistically against herbivores, but empirical evidence for synergy as a defence strategy remains limited.

Journal of the Royal Anthropological Institute, EarlyView.In the central highlands of Odisha, India, Kutia Kondh families navigate a precarious reality shaped by productive autonomy, decentralized authority, and material and relational uncertainty. Abundance and destitution are finely balanced in a world where humans, animals, ancestors, and spirits are co‐present and co‐dependent but also opaque and ...

Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it
