Independent Effects of Forest Cover and Fragmentation on the Distribution of Forest Breeding Birds
The aims o f this study were ( 1 ) to determine the relative importance o f the independent effects o f forest cover and fragmentation on the distribution o f forest breeding birds, and ( 2 ) to test the hypothesis that the negative ef fect o f forest fragmentation on species distribution increases with decreasing forest cover, i.e., the negative interaction ef fect o f forest cover and fragmen...
متن کاملSensitivity to fragmentation and spatial distribution of birds in forest fragments of northern paraná
In this study we investigated the relationship between the sensitivity to forest fragmentation of bird species and their habitat spatial distribution. We hypothesized that a homogenous spatial distribution is associated to habitat-generalist species, which would tend to be less sensitive to forest fragmentation; in contrast, a heterogeneous spatial distribution would drive to an increase of sen...

متن کاملSearching for bioindicators of forest fragmentation: passerine birds in the Atlantic forest of southeastern Brazil.
Aiming to evaluate the potential of Passerine birds as bioindicators of forest fragmentation, we studied the avifauna in the mountain region of the state of Rio de Janeiro by mist-netting between 2001 and 2005. We sampled six sites, including four small fragments (from 4 to 64 ha) in an agricultural area (Teresópolis), one second-growth forest (440 ha - Miguel Pereira) and a continuous forest (...
متن کاملLocal extinctions in flocking birds in Amazonian forest fragments
Questions: Does the tendency to join flocks predispose a bird species to local or global extinction? Does the ability to revise particular social preferences in fragmented landscapes confer greater persistence? Do solitary species of birds persist longer in small forest patches? Background: Social carnivores range more widely than solitary carnivores and are more prone to local extinction in fr...
