Geographic Distribution of Chagas Disease Vectors in Brazil Based on Ecological Niche Modeling

Journal of Tropical Medicine, Volume 2012, Issue 1, 2012., 2012
Although Brazil was declared free from Chagas disease transmission by the domestic vector Triatoma infestans, human acute cases are still being registered based on transmission by native triatomine species. For a better understanding of transmission risk, the geographic distribution of Brazilian triatomines was analyzed.

Animal‐Based Remedies as Complementary Medicines in the Semi‐Arid Region of Northeastern Brazil

Evidence-Based Complementary and Alternative Medicine, Volume 2011, Issue 1, 2011., 2011
Animals (and their derived products) are essential ingredients in the preparation of many traditional remedies. Despite its prevalence in traditional medical practices worldwide, research on medicinal animals has often been neglected in comparison to medicinal plant research.

The Free‐Range Rock Cavy (Kerodon rupestris) Communicates the Urgency of a Threat Using Different Alarm Calls

Ethology, Volume 131, Issue 10, Page 175-186, October 2025.
Rock cavy alarm calls are finely modulated by threat proximity. ABSTRACT This study examines whether rock cavies (Kerodon rupestris), which are social rodents, modulate their alarm calls in response to various threat contexts. Conducted across four sample areas within two study sites in the Brazilian Caatinga region, alarm calls were collected using ...

Serotonergic fibers distribution in the midline and intralaminar thalamic nuclei in the rock cavy (Kerodon rupestris)

Brain Research, 2014
The thalamic midline/intralaminar complex is part of the higher-order thalamus, which receives little sensory input, and instead forms extensive cortico-thalamo-cortical pathways. The midline thalamic nuclei connect with the medial prefrontal cortex and the medial temporal lobe.

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 ...

Planning for a future of changes: Prioritising areas for conservation of small mammals in the Caatinga, Brazil

Diversity and Distributions, Volume 30, Issue 8, August 2024.
Abstract Aim Human land‐use and climate change are two of the main threats affecting biodiversity, especially in arid/semiarid regions. The most effective way to protect the species in these ecosystems against these threats is through the delimitation of protected areas (PAs).

The suprachiasmatic nucleus and the intergeniculate leaflet in the rock cavy (Kerodon rupestris): Retinal projections and immunohistochemical characterization

Brain Research, 2010
In this study, two circadian related centers, the suprachiasmatic nucleus (SCN) and the intergeniculate leaflet (IGL) were evaluated in respect to their cytoarchitecture, retinal afferents and chemical content of major cells and axon terminals in the rock cavy (Kerodon rupestris), a Brazilian rodent species.
