O serviço de assistência técnica e extensão rural (ATER) é parte da estratégia central do projeto Assentamentos Sustentáveis na Amazônia (PAS): ele é capaz de promover mudanças nos padrões produtivos, alavancar o manejo integrado dos lotes rurais e fortalecer atividades de baixo impacto nas áreas abertas, reduzindo a demanda por novas áreas para a produção agropecuária.
Effects of partial throughfall exclusion on the phenology of Coussarea racemosa (Rubiaceae) in an east-central Amazon rainforest
Severe droughts may alter the reproductive phenology of tropical tree species, but our understanding of these effects has been hampered by confounded variation in drought, light and other factors during natural drought events. We used a large-scale experimental reduction of throughfall in an easterncentral Amazon forest to study the phenological response to drought of an abundant subcanopy tree, Coussarea racemosa. We hypothesized that drought would alter the production and the timing of reproduction, as well as the number of viable fruits.
