Gastrointestinal parasite assemblages from the wild rodent capybara (Hydrochoerus hydrochaeris) inhabiting a natural protected area from Argentina

, 2023
Knowledge about parasitic diseases of wildlife will help us to understand the dynamics of parasites and their effects on host populations. The capybara (Hydrochoerus hydrochaeris) is the largest living rodent in the world, and its distribution is ...

Integrated tick control on a farm with the presence of capybaras in a Brazilian spotted fever endemic region

Revista Brasileira de Parasitologia Veterinária, 2019
Ticks of the Amblyomma cajennense complex present high infestation rates. These ticks transmit the bacterium Rickettsia rickettsii, which causes Brazilian Spotted Fever.

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Dental Microwear Evidence of Holocene Dietary Variability in the Argentinian Pampas and Paraná Delta

American Journal of Biological Anthropology, Volume 191, Issue 1, September 2026.
ABSTRACT Objectives This study explores the subsistence strategies of Middle‐to‐Late Holocene human populations in the Argentinean Pampas and Paraná River Delta by analyzing dental microwear patterns. Materials and Methods We examined occlusal molar microwear textures of individuals from the Middle and Late Holocene recovered from 12 archaeological ...

Host, vector, and parasite dynamics: exploring intrinsic and extrinsic factors shaping tick‐borne filarial nematode transmission

Biological Reviews, Volume 101, Issue 4, Page 1779-1792, August 2026.
ABSTRACT Tick‐borne filarial nematodes are a complex and understudied group of parasites that rely on ticks for transmission in vertebrates. This review examines how intrinsic and extrinsic factors may influence the successful transmission of filarial nematodes in tick vectors, drawing insights from extensively studied haematophagous dipteran vector ...

“WANTED DEAD OR ALIVE:” BLACK VULTURES (CORAGYPS ATRATUS) FEEDING ON A LIVE CAPYBARA (HYDROCHOERUS HYDROCHAERIS) [PDF]

, 2018
∙ Although vultures are scavengers that feed mainly carcasses, they occasionally may feed on living tissue of vulnerable vertebrates. In South America, most records of vulture attacks on live animals refer to newborns of domes‐ tic mammals.

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.
