Simplified, Portable and Cost‐Efficient Airborne eDNA Metabarcoding to Expand Tropical Biodiversity Assessments

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).

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

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 ...

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.

Diversity and Activity Pattern of Terrestrial Mammal Species in Serra do Amolar, Brazilian Pantanal 巴西潘塔纳尔湿地阿莫拉尔山脉陆生哺乳动物物种的多样性及活动模式

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.

Neotropical mammal responses to megafires in the Brazilian Pantanal

Global Change Biology, Volume 30, Issue 4, April 2024.
We investigated how forest fires in the Brazilian Pantanal affected the occupancy of eight mammals and the density of jaguars and ocelots. We found that occupancy or habitat use declined for six of the species, with the giant armadillo being the most affected species, and the density of jaguars and ocelots remained stable, though the persistence of ...

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.
