Ants in Burned and Unburned Areas in Campos Rupestres Ecosystem

Sociobiology, 2016
Ground-dwelling ants have shown consistent resilience to fire in savanna environments. We carried out a study to investigate how ant community structure responds to fire in a harsh and fragile Cerrado ecosystem, the campos rupestres. We studied the change in the ant communities on a local scale subjected to fire in two rocky outcrop habitats at two ...

Microclimate drives demographic compensation in a narrow endemic tropical species

New Phytologist, Volume 250, Issue 1, Page 166-180, April 2026.
Summary Demographic compensation occurs when reductions in some vital rates are offset by increases in others, allowing populations to maintain similar performance across varying environments. This mechanism may help explain species' ecological distributions and range limits, yet its role at microenvironmental scales remains poorly understood.

Should I Stay or Should I Go? Using Open Data to Investigate Movements of the Streamer‐Tailed Tyrant (Gubernetes yetapa)

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Migration is a global phenomenon shaping bird assemblages in response to seasonal climate variations. The Streamer‐tailed Tyrant (Gubernetes yetapa) is a Neotropical bird associated with wetlands. Although considered common across most of its range, its natural history remains poorly understood, and some authors have suggested it may exhibit ...
