Forest conversion into pasture selects dung beetle traits at different biological scales depending on species pool composition. [PDF]
Briefly, we assess the impacts of forest conversion on the functional diversity of dung beetles in two different regions of Brazil, considering in particular intraspecific variation. To do this we conducted standardized surveys in seven forest fragments and adjacent pastures for every region and measured fourteen traits in individuals collected in each

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...

Evidence for seasonal cycles in deep‐sea fish abundances: A great migration in the deep SE Atlantic?
The authors demonstrate a significant correlation between epipelagic primary production and deep‐sea fish abundances at 1,500 m from 2010 to 2016 on the Angola margin. These findings highlight the importance of upper‐ocean processes to deep‐sea ecosystem functioning, and their potential vulnerability to future change.

Abstract The large increase in Eastern European migrants entering the Dutch labour market has led to concerns about their potential claim on Dutch unemployment benefits. We use a decomposition analysis to investigate differences in uptake of unemployment benefits between migrants and native Dutch employees by analysing register data for all employees ...

Dinâmica da Serapilheira em Floresta Estacional Semidecidual atingida por Barragem Hidrelétrica
O pulso de inundação é a principal força que atua nos processos ecossistêmicos de ambientes que sofrem influência direta do rio. Entre essas áreas encontramos as matas ripárias que têm sido intensamente impactadas pela instalação de hidrelétricas e seus ...

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.
