Abstract Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms evolutionarily, morphologically physiologically distinct from other trees, these differences have important consequences for services (e.g., carbon sequestration storage) in terms responses to climate change. We quantified global patterns palm relative abundance help improve understanding forests reduce uncertainty about under Location...

Palms are most diverse in warm and humid regions near the equator. Though palms remain relatively well conserved, they under increasing pressure from deforestation. Here, we analyze patterns of palm species richness relative to latitudinal gradient, sampling effort, deforestation Amazon, compare floristic similarity among Amazonian sub-regions. We built a database 17,310 records for 177 species. The areas with greatest were western, central northeastern principally at latitudes 0-5ºS....

A floristic inventory was carried out in an area of palm-dominated creek forest Jenaro Herrera, the northeast Peru. All trees ≥ 10 cm dbh were surveyed a one-hectare permanent plot using standard RAINFOR methodology. There 618 individuals belonging to 230 species, 106 genera and 43 families. The results showed that total basal 23.7 m2. three species with highest importance value indexes Iriartea deltoidea Ruiz & Pav., Oenocarpus bataua Mart. (Arecaceae) Carapa procera DC. (Meliaceae)....

Avaliar a sustentabilidade ambiental é uma tarefa complexa, implica em organizar um conjunto de conceitos e variáveis. Uma forma avaliação que se popularizou recentemente, partir Wackernagel et al. (1996), foi o da Pegada Ecológica. A presente pesquisa teve por objetivo avaliar envolvimento dos alunos Universidade Federal do Pará (UFPA) ações sustentáveis diretas seu padrão consumo, utilizando metodologia O resultado simulação apresentou pegada ecológica média 2,7 hectares pessoa, revelando...

Este estudo teve como objetivo fazer uma análise econômica da cadeia produtiva de açaí na comunidade São João Batista, no município Abaetetuba, Pará, Brasil. Realizaram-se 31 entrevistas semi-estruturadas e abertas a famílias pequenos médios produtores açaí. Essa atividade gerou maior renda época safra do açaí, que variou entre R$ 800 até pouco mais 1.000 nos meses produção (agosto-outubro). O preço venda dos primários variou, acordo com safra, tendo um baixo custo, durante o pico...
