Most have been reduced to isolated trees and small forest fragments in which native tree species reproduce poorly. The replacement of native birds by introduced generalists may be contributing to dry forest decline through modification of seed dispersal patterns. To document seed dispersal by introduced birds, we conducted foraging observations on fleshy-fruited trees and measured seed rain under trees and in adjacent open areas for http://www.selleckchem.com/products/z-vad-fmk.html 1 year in a dry forest dominated by native trees. Although trees covered only 15.2 percent of the study area, 96.9 percent of the bird-dispersed seeds were deposited beneath them. The Japanese white-eye (Zosterops japonicus) was the principal dispersal agent. Among bird-dispersed seeds, those of the invasive tree Bocconia frutescens accounted for 75 percent of all seeds collected beneath trees (14.8?seeds/m2/yr) and the invasive shrub Lantana camara accounted for 17 percent. Although nearly 60 percent of the reserve's native woody species possess fleshy fruits, introduced birds rarely disperse their seeds. Native trees accounted for http://www.selleckchem.com/products/ly2157299.html plants may eventually replace the remaining native http://www.selleck.cn/products/XL184.html flora. ""Large areas of the Rio Negro basin in Amazonia are covered by continuous tracts of tropical forest, but have few primate species. This is anomalous considering the general relationship between area and number of species. One possibility is that much of the forest is unsuitable habitat for most primates and the area of suitable habitat is much less than the forested area. This has important consequences for the design of reserves and predictions of the consequences of climate change, which tend to be based on broad categories based on satellite images, and not on information of species distributions within those broad categories. The study was conducted through diurnal and nocturnal line-transect surveys in the Biodiversity Research Program 25-km2 permanent grid in Viru�� National Park, which has vegetation associations typical of much of northern Amazonia. The highest primate diversity and abundances occurred in tall terra firme forests (58%), whereas inundated forests and scrublands, which cover 42 percent of the survey grid and 90.8 percent of the Viru�� National Park, have virtually no primates.
