Avian responses to fragmentation of the Maulino Forest in central Chile
Depending on the mosaic of habitats that is created, forest fragmentation can reduce the abundance and diversity of forest birds. Temperate deciduous forests in South America are rapidly being replaced by pine plantations, ...
Are corridors, fragment size and forest structure important for the conservation of leaf-litter lizards in a fragmented landscape?
(CAMBRIDGE UNIV PRESS, 2009)
To investigate the implications of forest fragmentation for conservation of leaf-litter lizards the importance of fragment size, corridors and forest structure was examined in 20 forest fragments and six localities within ...
Bird diversity and abundance in forest fragments and Eucalyptus plantations around an Atlantic forest reserve, Brazil
(Kluwer Academic Publ, 2001-05-01)
Little of Brazil's remaining Atlantic forest is protected, so it is important to assess how well the region's wildlife can persist in areas/habitats outside reserves. We studied bird diversity and abundance during 546 point ...
Changes in forest structure and tree recruitment in Argentinean Chaco: Effects of fragment size and landscape forest cover
(Elsevier Science, 2013-05)
Subtropical Argentinean Chaco forests have been severely deforested and fragmented due to agriculture during the last six decades. The most affected forests are located in areas that are most favorable for crops. This ...
Dung decomposition and associated beetles in a fragmented temperate forest
(Sociedad de Biología de Chile, 2004)
Is top-down control by predators driving insect abundance and herbivory rates in fragmented forests?
The effects of forest fragmentation on ecological interactions and particularly on food webs have scarcely been analysed. There is usually less herbivory in forest fragments than in continuous forests. Here we hypothesize ...
Decreased frugivory and seed germination rate do not reduce seedling recruitment rates of Aristotelia chilensis in a fragmented forest
Habitat fragmentation reduces frugivorous bird abundance. Such a reduction may lead to a reduction in seed dispersal, thereby compromising seedling recruitment rate with far reaching consequences for plant population ...
Inquiring into the causes of depressed folivory in a fragmented temperate forest
Folivory is lower in forest fragments of the Maulino forest than in continuous stands. We experimentally assessed whether depressed folivory is related to a reduction in foliar palatability caused by the more xeric ...
Associations of Forest Cover, Fragment Area, and Connectivity with Neotropical Understory Bird Species Richness and Abundance
Theoretical and empirical studies demonstrate that the total amount of forest and the size and connectivity of fragments have nonlinear effects on species survival. We tested how habitat amount and configuration affect ...
