From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

The Anatomical Record, Volume 309, Issue 8, Page 2199-2220, August 2026.
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.

Prolactin and Triiodothyronine Modulate Seasonal Variation in Brown Adipose Tissue in Djungarian Hamsters

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 710-718, August 2026.
ABSTRACT Seasonal photoperiodic cycles regulate energy rheostasis in many animals. Brown adipose tissue (BAT) and the liver are key metabolic organs that show remarkable plasticity in response to photoperiodic conditions. Prolactin (PRL) and thyroid hormones are endocrine signals that transmit neural‐derived photoperiodic time measurement encoding to ...

Evolution of Acidic Mammalian Chitinase Gene (CHIA) is Related to Insectivory Feeding in Rodents

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study provides the first systematic investigation into the molecular evolution of the acidic mammalian chitinase (CHIA) gene across 37 rodent species with diverse diets. Results demonstrate that the CHIA gene has been lost or pseudogenized in obligate herbivores, while being maintained under purifying selection in chitin‐consuming lineages, with ...
