Experimental heteroxenous cycle of Lagochilascaris minor Leiper, 1909 (Nematoda: Ascarididae) in white mice and in cats

Memorias do Instituto Oswaldo Cruz, 1992
Reports of natural infections of sylvatic carnivores by adult worms of species similar to Lagochilascaris minor in the Neotropical region led to attempts to estabilish experimental cycles in laboratory mice and in cats.

Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

Austral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

Mammal Review, Volume 55, Issue 3, July 2025.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Understanding mammary activity in red-rumped agouti and implications for management and conservation of this Neotropical game species

Brazilian Journal of Biology, 2017
The red-rumped agouti (Dasyprocta leporina) produces precocial young and is the most hunted and farmed game species in several Neotropical countries. An understanding of the reproductive biology, including the relationship between litter size and teat ...

Thinking with Amazonian Indigenous Peoples to expand ideas on domestication

People and Nature, Volume 7, Issue 3, Page 560-574, March 2025.
Abstract Indigenous knowledges are being increasingly recognized as fundamental for environmental governance, ecosystem management and biodiversity conservation. However, they tend to be recognized by Western science only when they converge with Western scientific knowledge, while ontological differences are generally treated as irrelevant or ...

Effect of different anesthetic protocols on erection, ejaculation and sperm parameters in red-rumped agoutis (Dasyprocta leporina) subjected to electroejaculation

Theriogenology Wild, 2023
: With the aim of contributing to the development of assisted reproduction for red-rumped agouti germplasm conservation, we compared different anesthetic protocols for electroejaculation in agoutis in terms of anesthetic parameters, functions of erection

Medium and large mammal responses to fire in a neotropical savanna system in Guyana

Biotropica, Volume 57, Issue 1, January 2025.
Mammal responses to fire—both natural and man‐made—in an Indigenous savanna landscape in Guyana were researched with transects for animal signs and live sightings. Species richness showed a non‐linear relationship with time since fire, likely due to differing responses from individual species, which may be explained by habitat preference and post‐fire ...

The Agoutis: A Future Model for Ecologically Relevant Neuroscience and Physiology In Natura

Ethology, Volume 130, Issue 12, December 2024.
Recent advances in behavioral monitoring and wireless physiology make neuroscience in the wild a viable option for larger animal models. Here we spotlight one such species, the agouti (Dasyprocta spp.) a large promising rodent model for the future of neuroscience in natura.
