Informal supply chains of wild meat from rural Amazonia and food security in an urban center
Conservation Biology, EarlyView.Abstract Iquitos, the most populated city in the Peruvian Amazon, is a hub in the regional supply chain of wild meat and supplies urban consumers. Studies on wild meat consumption have focused primarily on markets, limiting the scope of species considered to those that are economically valuable and potential inferences from those data.

Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests
Ecology, Volume 107, Issue 3, March 2026.Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest
Biotropica, Volume 58, Issue 2, March 2026.We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

The coronary arteries of the agouti (Agouti paca, Linnaeus, 1766) [PDF]
Biotemas, 2009 The present study aimed to describe the coronary arteries in the agouti. Twelve hearts set, in a 10% formaldehyde aqueous solution, were used. The presence of left and right coronary arteries was observed in all hearts.

Fallen Logs Act as Natural Bridges Over Rivers in a Tropical Wet Forest
Biotropica, Volume 58, Issue 1, January 2026.We studied how vertebrate species used logs as bridges over rivers in a tropical rainforest. Most mammals present in the area used logs, but the frequency and probability of crossing varied widely among species, between seasons, and in relation to the dimensions of the log and the river below.

Social media videos highlight the impacts of the illegal use of snares on Brazilian biodiversity
People and Nature, Volume 7, Issue 11, Page 2811-2820, November 2025.Abstract Snares are one of the most used types of non‐selective traps for hunting worldwide, though their use is prohibited in many countries, including Brazil. Indiscriminate and unmonitored use of snares can induce serious conservation problems, particularly in megadiverse countries where higher species richness and diversity mean that the ...

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.

Human impact on mammal diversity in Secoya Land, Ecuadorian Amazon
ACI Avances en Ciencias e Ingenierías, 2009 To evaluate the impact of hunting on the diversity of mammals in the Secoya land in the northeastern of Ecuador, we using a non-invasive methodology based on the use of "camera traps" located in forests at different distances from Secoya settlements from

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 ...
