Dispersal Ability Reduces Thermal Specialization and Prevents Climate-Driven Extinctions in a Neotropical Rainforest. [PDF]

open access: yesGlob Chang Biol
We found that species with higher dispersal ability are less specialized in their temperature tolerances and more likely to persist under climate change. By analyzing more than 6 thousand species of plants, invertebrates, and vertebrates distributed in the Atlantic Rainforest, we show that more mobile species can avoid extinction by shifting locations,

Fish on Fire: Shifts in Amazonian fish communities after floodplain forest fires

open access: yesJournal of Applied Ecology, Volume 60, Issue 8, Page 1637-1646, August 2023., 2023
Amazonian fish communities change after floodplain forest fires. Unburnt forests have diverse fish communities, with a large proportion of unique and small omnivorous species. In contrast, carnivores and detritivores become more common in fire scars and white‐sand savannas formed after forest fires. Less omnivore fish after forest fires can reduce tree

Effects of time since invasion and control actions on a coastal ecosystem invaded by non‐native pine trees

open access: yesEcological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Pine invasion reduced native species abundance, plant cover, richness and diversity, with an increase over time since invasion. Species diversity and richness were lower in the managed area than in the area that had not been invaded. Restoration activities are therefore required to increase native species diversity.

El Niño impacts on human‐modified tropical forests: Consequences for dung beetle diversity and associated ecological processes

open access: yesBiotropica, Volume 52, Issue 2, Page 252-262, March 2020., 2020
Abstract Our knowledge of how tropical forest biodiversity and functioning respond to anthropogenic and climate‐associated stressors is limited. Research exploring El Niño impacts are scarce or based on single post‐disturbance assessments, and few studies assess forests previously affected by anthropogenic disturbance.
