Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems
ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...

Myxobiota of the Brazilian Atlantic Forest: species on oil palm tree (Elaeis guineensis, Arecaceae)
Elaeis guineensis Jacq. (Arecaceae), the oil palm tree, serves as a phorophyte for many different groups of organisms, someof whichhelp decompose organic matter comingfromthe organs of the tree itself or fromremainsof other plants retained in leaf ...

ESTIMATIVA DE BIOMASSA EM UMA FLORESTA TROPICAL NO MUNICÍPIO DE MAUÉS - AM, BRASIL
O sensoriamento remoto (SR), sistema de informação geográfica (SIG) e sistema de posicionamento global (GPS) são importantes ferramentas para as diversas etapas de inventários florestais, inclusive para as estimativas de biomassa. O objetivo deste trabalho foi consolidar uma metodologia para a espacialização ou mapeamento das variáveis biofísicas ...

ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

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

Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Influências Remotas Sobre a Amazônia e dela Sobre Outras Regiões: o Homem, a Flora e a Fauna [PDF]
A última e maior reserva florestal tropical do planeta que precisa ser conservada e explorada conscientemente, preservando o meio ambiente (desenvolvimento sustentável). Pois sua destruição alterará o clima da América do Sul, principalmente.
