Measuring mosquito diversity patterns in an Amazonian terra firme rain forest.
We reanalyzed a dataset consisting of approximately 10,700 crepuscular and night-biting female mosquitoes (Culicidae) collected over 12 mo in the canopy and understorey of primary Amazonian rain forest. We investigate whether vertical habitat stratification and rainfall modified major ecological parameters of this mosquito ensemble, combining descriptive and hypothesis-testing statistics with s...
متن کاملSpecies Richness and Density of Palms in Terra Firme Forests of Amazonia
f ABSTRACT The characteristics of the palm community in Amazonian terra firme forests are defined from three inventories carried out in the lower Tocantins (east), the lower Rio Negro (center), and the lower Ucayali (west) valleys. At all sites, most of the palms are small, understory species; the palm community is mainly under 10 m in height (99.8 to 99.9%); and adult arborescent palms occur a...
متن کاملGeological control of floristic composition in Amazonian forests
AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...
متن کاملRapid tree carbon stock recovery in managed Amazonian forests
While around 20% of the Amazonian forest has been cleared for pastures and agriculture, one fourth of the remaining forest is dedicated to wood production. Most of these production forests have been or will be selectively harvested for commercial timber, but recent studies show that even soon after logging, harvested stands retain much of their tree-biomass carbon and biodiversity. Comparing sp...
