Three‐Dimensional Limb Kinematics in Brown‐Throated Three‐Toed Sloths (Bradypus variegatus) During Suspensory Quadrupedal Locomotion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 5, Page 564-577, June 2025.
ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

Contribuição ao estudo da anatomia macroscópica dos rins e das estruturas vasculares sanguíneas no hilo renal do bicho-preguiça (Bradypus variegatus)

Medicina Veterinária, 2020
Devido à ação antrópica sob o habitat natural do Bradypus variegatus, esta espécie encontra-se em risco de extinção. Um dos principais pontos para a conservação de espécies em extinção é conhecer sua anatomia e fisiologia. Porém, para o B.

How much seagrass does a dugong need? Metabolic rate of live wild dugongs, Dugong dugon, determined through indirect calorimetry (oxygen consumption)

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Deterioration of seagrass beds worldwide has raised concern about the future of dugongs because almost all aspects of their life history depend on availability of seagrass. Understanding their energy metabolism and consequently how much seagrass they need will inform protective conservation strategies for dugongs. This study determined resting

Morphological analysis of teeth in Bradypus variegatus Schinz, 1825 (Mammalia, Bradypodidae)

Biotemas, 2016
Among the sloth species, we may highlight the Bradypus variegatus, found especially in northeastern Brazil. Given the importance and scarcity of information about the digestive tract of wild animals, this article aims to describe dental morphology in ...

Anthropogenic extinctions explain most size and trophic mismatches between large mammalian primary consumers from Amazonian and African rainforests

Biotropica, Volume 57, Issue 1, January 2025.
Present‐day Amazonia has an impoverished fauna of large folivorous mammals by comparison with African rainforests, but recent fossil discoveries suggest that late‐Quaternary anthropogenic extinctions could account for most size and trophic faunal mismatches.

Cathemerality: a key temporal niche

Biological Reviews, Volume 99, Issue 2, Page 329-347, April 2024.
ABSTRACT Given the marked variation in abiotic and biotic conditions between day and night, many species specialise their physical activity to being diurnal or nocturnal, and it was long thought that these strategies were commonly fairly fixed and invariant.
