Living in the Pyrocene: Assemblage‐Wide Terrestrial Vertebrate Responses to Mega‐Fires in the Pantanal Wetlands

Ecology and Evolution, Volume 16, Issue 8, August 2026.
More than 60% of Serra do Amolar within the Pantanal Wetlands, Brazil, was burned in 2020. Nine vertebrate species showed a dependency on forest areas, which are more vulnerable to fires in this region, despite the fire not having shown a direct effect on the occupation.

The Impact of Food Properties on Jaw Movements in Rodents: A Comparison Between Myomorphous and Hystricomorphous Species

Journal of Morphology, Volume 287, Issue 8, August 2026.
We investigated the masticatory movements of two of the three main cranial‐mandibular morphological groups in Rodents (two species each) using 3D X‐ray reconstruction. We found that both groups use different movements and modulate their chewing differently in response to different food items.

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.

Long‐term changes in functional diversity and its implications for mammalian conservation and ecological restoration in a grassland ecosystem

Functional Ecology, Volume 40, Issue 8, Page 2379-2391, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Paleontological data provide information on natural environments prior to human influence, which are useful for tracking changes in ecosystem functioning through time. During the Late Pleistocene, about 10% of terrestrial mammalian species were extinct in South America.

Informal supply chains of wild meat from rural Amazonia and food security in an urban center

Conservation Biology, Volume 40, Issue 4, August 2026.
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.
