International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 Fragmentation and destruction of a habitat are strongly relevant aspects to determine the richness and the dynamics of the mammals in ecosystems. This study, developed from October, 2010 to July, 2011 in three Atlantic Forest remnants in Ipumirim, SC, Brazil, aims at identifying the diversity of large‐ and medium‐sized nonflying mammals and verifying ...

Diversity of medium and large neotropical mammals in an area of mixed rain forest
Acta Scientiarum: Biological Sciences, 2018 Medium and large mammals (> 1 kg) were studied using camera traps with active sensors in a Conservation Unit located in an area of Mixed Rain Forest or Araucaria Forest (Atlantic Forest at altitude) in the South of Brazil, as a method for investigating

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Background. Kleiber’s law describes the quantitative association between whole‐body resting energy expenditure (REE, in kcal/d) and body mass (M, in kg) across mature mammals as REE = 70.0 × M0.75. The basis of this empirical function is uncertain. Objectives.

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.

Environmental DNA, Volume 8, Issue 2, March/April 2026.This study introduces a liquid‐based sampling approach for airborne eDNA (A). Using a greenhouse mock‐community for optimization (B), we use the novel approach in the tropical Andes to demonstrate its versatility and the complementary nature of airborne and aquatic eDNA for molecular biodiversity assessments (C).

Biotropica, Volume 58, Issue 2, March 2026.Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

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.

The relationship between external temperature and daily activity in a large rodent (Dasyprocta azarae) in the Brazilian Pantanal [PDF]
Journal of Tropical Ecology, 2015 Abstract:Daily activity patterns reflect interactions between circadian mechanisms and environmental stimuli. Among these stimuli, temperature can be an important factor affecting activity budgets. To sample the agouti (Dasyprocta azarae), a systematic camera-trap grid was established with 50 independent sampling sites.

Wildlife Letters, Volume 3, Issue 2, Page 56-63, June 2025.The Serra do Amolar, located in the Brazilian Pantanal, is a crucial but understudied area for biodiversity conservation. Through camera traps, we recorded 29 mammal species, including three rodent species documented for the first time in the area: Cavia aperea, Cuniculus paca, and Holochilus chacarius.

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.
