Anthropogenic disturbances infiltrate forest fragments

Anthropogenic disturbances infiltrate forest fragments.

In the years after Edward O. Wilson and Robert MacArthur’s seminal book, The Theory of Island Biogeography (1), which laid the foundations for understanding species diversity and extinction rates in isolated habitats, was published in 1967, a flurry of papers erupted on the effect of fragmentation in tropical rainforests. The big question at that time was whether it would be more advisable to p...

Species richness and relative abundance of birds in natural and anthropogenic fragments of Brazilian Atlantic forest

Bird communities were studied in two types of fragmented habitat of Atlantic forest in the State of Paraná, southern Brazil; one consisted of forest fragments that were created as a result of human activities (forest remnants), the other consisted of a set of naturally occurring forest fragments (forest patches). Using quantitative data obtained by the point counts method in 3 forest patches an...

A meta-analysis of community response predictability to anthropogenic disturbances.

Disturbances often lead to changes in average values of community properties; however, disturbances can also affect the predictability of a community's response. We performed a meta-analysis to determine how response predictability, defined as among-replicate variance in diversity and community abundance, is affected by species removals, species invasions, nutrient addition, temperature increas...
