Deforestation Impacts on Bat Functional Diversity in Tropical Landscapes
Functional diversity is the variability in the functional roles carried out by species within ecosystems. Changes in the environment can affect this component of biodiversity and can, in turn, affect different processes, including some ecosystem services. This study aimed to determine the effect of forest loss on species richness, abundance and functional diversity of Neotropical bats. To this ...
متن کاملBeta-Diversity in Tropical Forests
Condit et al. (1) and Duivenvoorden et al. (2) discussed beta-diversity of tropical rainforest trees and came to some conclusions that we find problematic. Condit et al. argued that betadiversity of lowland rainforest trees is higher in Panama than in western Amazonia, based on observation of a steeper distance-decay of floristic similarity in 34 Panamanian tree plots compared with 16 Ecuadoria...
متن کاملLong-term impacts of logging on forest diversity in Madagascar.
Ecological perturbations can either be necessary for maintaining tropical forest diversity or responsible for its decline, depending on the scale, nature, and frequency of the disturbance. Anthropogenic disturbances such as logging and subsistence agriculture may promote the establishment of nonnative, invasive plant species, potentially affecting forest structure and diversity even long after ...
متن کاملDeforestation and tropical insect extinctions.
In a study comparing historical and recent records of forest-dwelling Helictopleurus dung beetles across Madagascar, Hanski et al. (2007) reported that species not found in Madagascar-wide sampling in 2002– 2006 have experienced a significantly higher level of deforestation within their known geographical ranges than those species that were recorded. They suggested that deforestation is respons...
متن کاملBeta-diversity in tropical forest trees.
The high alpha-diversity of tropical forests has been amply documented, but beta-diversity-how species composition changes with distance-has seldom been studied. We present quantitative estimates of beta-diversity for tropical trees by comparing species composition of plots in lowland terra firme forest in Panama, Ecuador, and Peru. We compare observations with predictions derived from a neutra...
