Big data, big problems? How to circumvent problems in biodiversity mapping and ensure meaningful results

Ecography, Volume 2024, Issue 8, August 2024.
Our knowledge of biodiversity hinges on sufficient data, reliable methods, and realistic models. Without an accurate assessment of species distributions, we cannot effectively target and stem biodiversity loss. Species range maps are the foundation of such efforts, but countless studies have failed to account for the most basic assumptions of reliable ...

Using Remote Sensing and Random Forest to Assess the Conservation Status of Critical Cerrado Habitats in Mato Grosso do Sul, Brazil

Land, 2016
Brazil’s Cerrado is a highly diverse ecosystem and it provides critical habitat for many species. Cerrado habitats have suffered significant degradation and decline over the past decades due to expansion of cash crops and livestock farming across South ...

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 ...

Conservation detection dogs: A critical review of efficacy and methodology

Ecology and Evolution, Volume 14, Issue 2, February 2024.
Conservation detection dogs (CDD) can be effective and applied to possibly limitless conservation scenarios but moving forward researchers must provide more consistent and detailed methodologies so that comparisons can be conducted, results are more easily replicated and progress can be made in standardising CDD work. This review aims to summarise what

NEW DATA ON THE REPRODUCTIVE LIFESPAN OF GIANT ARMADILLOS (PRIODONTES MAXIMUS) IN THE WILD

Oecologia Australis
The reproductive lifespan of a species is a key parameter used in a multitude of ecological analyses and conservation status assessments. A long-term study on giant armadillos (Priodontes maximus) in the Brazilian Pantanal using camera traps demonstrated that a female had a pup when she was at least 20 years old.

Environmental and Anthropogenic Predictors Influence the Diversity of Nonflying Mammals in a Native Savanna Landscape of Northern South America

International Journal of Zoology, Volume 2024, Issue 1, 2024.
The native savannas of eastern Colombia cover about six percent of the Neotropical savannas. Within these 17 million hectares, the current composition of nonflying mammals evidenced colonization from Andean, Guyanese, and Amazonian speciation centers and endemism processes.

COMPOSITION OF MEDIUM AND LARGE MAMMALS IN FOREST RESERVE IN THE CERRADO OF BRAZIL CENTRAL

Revista Árvore
Knowledge about fauna location and distribution is very important for animal biology understanding. Conservation Units are relevant to biodiversity when considering factors such as hunting, agricultural expansion and forest fires.

Patterns of mammal subsistence hunting in eastern Amazon, Brazil

Wildlife Society Bulletin, 2018
Hunting affects many threatened mammal species in Brazil. We described subsistence hunting patterns for medium‐ (1.0–14.9 kg) and large‐sized (>15 kg) mammal species by a rural community in the eastern Amazon, Brazil. From April 2012 to November 2013, we
