Filtração de partículas através do dossel de uma floresta tropical úmida

Boletim do Museu Paraense Emílio Goeldi - Ciências Naturais, 2014
Understanding the dinamics of filtration of pollen and spores by plant canopies is crucial to the in the modelling of their dispersal, yet few studies have quantified filtration. Here, we examine the decline in the density of flour particles descending through a 40 m-tall tropical canopy on a windless day at Caxiuanã National Forest, Pará, Brazil ...

Dinâmica sazonal da produção e decomposição de serrapilheira em floresta tropical de transição [PDF]

Revista Brasileira de Engenharia Agrícola e Ambiental, 2009
Em função de se analisar a produção, dinâmica e decomposição de serrapilheira em busca da sazonalidade do microclima em uma floresta tropical de transição Amazônia Cerrado, propõe-se estimar a produção de serrapilheira, por meio de caixas de coleta de 1 m² e o acúmulo de serrapilheira sobre o solo por meio de quadrantes de 25 x 25 cm, distribuídos ...

When Calves Get Vulnerable, Ocelots (Leopardus pardalis) Get Bold: A Camera Trap Record of Opportunistic Foraging in a Fragmented Landscape

Biotropica, Volume 58, Issue 2, March 2026.
We report the first confirmed record of an ocelot (Leopardus pardalis) dragging a newborn calf in a degraded forest fragment of southeastern Brazil. Using camera trap records, we reveal an opportunistic foraging event involving a vulnerable domestic prey within a highly fragmented landscape.

Large emissions from floodplain trees close the Amazon methane budget [PDF]

, 2017
Wetlands are the largest global source of atmospheric methane (CH4), a potent greenhouse gas. However, methane emission inventories from the Amazon floodplain, the largest natural geographic source of CH4 in the tropics, consistently underestimate the ...

CARACTERIZAÇÃO ESPECTRAL DE PROPRIEDADES ÓPTICAS DE AEROSSÓIS EM REGIÃO DE FLORESTA TROPICAL

Nativa, 2018
Aerossóis atmosféricos desempenham um papel importante no equilíbrio de energia do sistema Terra-atmosfera. Medidas de aerossóis foram realizadas em área de floresta tropical utilizando fotômetro solar da rede global AERONET. Dados de 4 anos permitiram classificar as propriedades óticas dos aerossóis, definindo a climatologia para área de floresta ...

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

Biotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.
