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 کاملTermite (Insecta: Isoptera) Species Composition in a Primary Rain Forest and Agroforests in Central Amazonia
Termites play important roles in organic matter decomposition, nutrient cycling, and soil structure in tropical rain forests. When forests are replaced by agriculture, termite species richness, abundance, and function often decline. We compared the termite assemblage of a primary forest site with that of a low plant diversity, palm-based agroforest (five plant species) and a high plant diversit...
متن کاملResponses of Understory Rain Forest Birds to Road Edges in Central Amazonia
In the lowland tropical rain forest of central Amazonia, I investigated the responses of understory bird communities to forest edges bordering a narrow (<40 m width), unpaved road. From 3681 mist-net captures, bird abundance and composition were examined at three distances (10, 70, and 130 m) from forest edge. The degree to which regrowth vegetation along forest borders reduced edge effects was...
متن کاملThroughfall in a Puerto Rican lower montane rain forest: A comparison of sampling strategies
During a one-year period, the variability of throughfall and the standard errors of the means associated with different gauge arrangements were studied in a lower montane rain forest in Puerto Rico. The following gauge arrangements were used: (1) 60 fixed gauges, (2) 30 fixed gauges, and (3) 30 roving gauges. Stemflow was measured on 22 trees of four different species. An ANOVA indicated that m...
