The utilization of aquatic bushmeat from small cetaceans and manatees in South America and West Africa

open access: yesFrontiers in Marine Science, 2016
Aquatic bushmeat can be defined as the products derived from wild aquatic megafauna (e.g. marine mammals) that are used for human consumption and non-food purposes, including traditional medicine.

Diving Behaviour and Foraging Ecology of Female Southern Elephant Seals from Patagonia

open access: yes, 1998
Published by and copyright by Aquatic Mammals.We asked if non-gestating adult female southern elephant seals, Mirounga leonina, from Peninsula Valdes, Argentina, forage on the wide continental shelf off the peninsula during the post-breeding trip to sea (

Microbiological Assessment of Some Culturable Microbiotafrom Clinically Healthy Bottlenose Dolphins (Tursiops truncatus) Under Human Care

open access: yes, 2016
The mammalian commensal microbiota constitutes over a thousand bacterial phylotypes (Suchodolski, 2014) and confers important functions, including a mucosal barrier function, a metabolic function, and an immune regulatory function, which contribute to ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Catalog of Osteological Collections of Aquatic Mammals from Mexico [PDF]

open access: yes, 1991
This paper compiles available information on osteological and other anatomical specimens of at least 51 species of aquatic mammals (34 extant, one recently extinct and 16 fossil) collected in Mexico between 1868 and 1990 and housed in 29 scientific ...

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

open access: yesThe Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Inter‐ and intraspecific variation in theropod dinosaur dental microwear and its palaeoecological implications

open access: yesThe Anatomical Record, EarlyView.
Abstract Differences in skull and tooth morphology, stomach contents, and estimated bite force between medium‐to‐large sized (≥100 kg) predatory theropod dinosaurs have long been suspected to correlate with differences in their diets and dietary guilds (e.g., hypercarnivory, piscivory).
