The Impact of Food Properties on Jaw Movements in Rodents: A Comparison Between Myomorphous and Hystricomorphous Species

Journal of Morphology, Volume 287, Issue 8, August 2026.
We investigated the masticatory movements of two of the three main cranial‐mandibular morphological groups in Rodents (two species each) using 3D X‐ray reconstruction. We found that both groups use different movements and modulate their chewing differently in response to different food items.

Ultrasound call detection in capybara [PDF]

Pesquisa Veterinária Brasileira, 2012
The vocal repertoire of some animal species has been considered a non-invasive tool to predict distress reactivity. In rats ultrasound emissions were reported as distress indicator. Capybaras[ vocal repertoire was reported recently and seems to have ultrasound calls, but this has not yet been confirmed.

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, Volume 40, Issue 8, Page 2379-2391, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Rickettsiales in South America: A Systematic Review of Their Molecular Detection and Distribution in Arthropods and Vertebrates

Public Health Challenges, Volume 5, Issue 2, June 2026.
ABSTRACT Bacteria of the order Rickettsiales comprise a diverse group of obligate intracellular microorganisms that are globally distributed and highly prevalent in tropical and subtropical regions. In South America, these bacteria have been associated with arthropod vectors, such as ticks, fleas, mites, lice, and certain dipterans, as well as with a ...

Tomographic imaging of lunulae in capybara knees

, 2011
The lunulae, ossification of the meniscus, are found in several species of rodents. Some studies suggest that the lunulae may be anatomical features, because there are not any pathological findings in microscopy.

Spatial Ecology and Habitat Selection by Jaguars and Pumas in a Protected Area in the Atlantic Forest of Brazil

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding animal distribution is crucial for elucidating natural history, population dynamics, and inter‐ and intraspecific interactions. This knowledge informs the planning and evaluation of management and conservation strategies, particularly for sympatric, scarce, and threatened species such as jaguars (Panthera onca) and pumas (Puma ...
