Mobilização social para adaptação à mudança climática: uma experiência na bacia do Rio Pardo (RS)

open access: yesRevista PerCursos, 2018
Face à inatividade de governos nacionais em promover adaptação à mudança do clima, a adaptação pela esfera subnacional vem ganhando relevância no debate acadêmico.

Environmental Filtering Dominates Over Dispersal Limitation in Structuring Highly Mobile Tropical Communities

open access: yesJournal of Biogeography, Volume 53, Issue 6, June 2026.
ABSTRACT Aim To disentangle the relative roles of environmental filtering (niche processes) and dispersal limitation (neutral processes) in structuring communities of a highly mobile tropical taxon, and to assess the implications for biodiversity patterns at broad spatial scales. Location Brazilian Amazon. Time Period 2011–2019.

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

open access: yesSedimentology, Volume 73, Issue 4, Page 1225-1243, June 2026.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Climate‐induced shifts in long‐term tropical tree reproductive phenology: Insights from species dependent on and independent of biotic pollination

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1286-1298, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The dependence on biotic pollination may constrain plant phenological responses because flowering time ultimately defines reproductive success. We proposed a local‐scale study combining long‐term phenology and experimental data to evaluate how a key functional trait—the

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna. We conducted this study in the Cerrado, where severe frost events allowed us to compare fruit production and frugivorous bird abundance before and after the disturbance.
