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 کاملFalling palm fronds structure amazonian rainforest sapling communities.
The senescence and loss of photosynthetic and support structures is a nearly universal aspect of tree life history, and can be a major source of disturbance in forest understoreys, but the ability of falling canopy debris in determining the stature and composition of understorey communities seems not to have been documented. In this study, we show that senescent fronds of the palm Iriartea delt...
متن کاملAre Microhabitat Preferences of Coexisting Species Under Selection and Adaptive?
Microhabitat preferences are assumed to be adaptive, suggesting that fitness is higher in preferred microhabitats and potentially reflecting natural selection on habitat choices. I examined microhabitat preferences and adaptiveness of preferences for seven bird species coexisting in high elevation snowmelt drainages based on study of microhabitat and survival of 1556 nests. Habitat features in ...
متن کاملMicrohabitat locality allows multi-species coexistence in terrestrial plant communities
Most terrestrial plant communities exhibit relatively high species diversity and many competitive species are ubiquitous. Many theoretical studies have been carried out to investigate the coexistence of a few competitive species and in most cases they suggest competitive exclusion. Theoretical studies have revealed that coexistence of even three or four species can be extremely difficult. It ha...
