Effect of fragmentation on the Costa Rican dry forest avifauna
(2016)
Deforestation and changes in land use have reduced the tropical dry forest to isolated forest patches in northwestern Costa Rica. We examined the effect of patch area and length of the dry season on nestedness of the entire ...
Vulnerability of small forest patches to fire in the Paraiba do Sul River Valley, southeast Brazil: Implications for restoration of the Atlantic Forest biome
(2020-06-01)
The Atlantic Forest biome, a biodiversity hotspot historically threatened by deforestation and human disturbance, has recently seen a net gain in native forest cover due to changes in land use, enactment of new laws, and ...
Local extinctions of obligate frugivores and patch size reduction disrupt the structure of seed dispersal networks
(Wiley-Blackwell, 2018-11-01)
A central problem in ecology is to understand how human impacts affect plant-animal interactions that lead to effective seed dispersal services for plant communities. Seed dispersal services are the outcome of plant-frugivore ...
Patch-size and isolation effects in the Fisher-Kolmogorov equation
(Springer, 2008-10-01)
We examine the classical problem of the existence of a threshold size for a patch to allow for survival of a given population in the case where the patch is not completely isolated. The surrounding habitat matrix is ...
Ant community patterns in highly fragmented Chaco forests of central Argentina
(Wiley Blackwell Publishing, Inc, 2019-04)
The Chaco is the largest dry forest biome in South America and one of the regions most threatened by agricultural intensification. As a consequence, in several areas Chaco forests persist as forest remnants of different ...
Priorização de remanescentes florestais visando a conservação da biodiversidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Planejamento e Uso de Recursos Renováveis - PPGPUR-SoCâmpus Sorocaba, 2019-02-27)
The Atlantic forest fragmentation is considered a serious threat for biodiversity since this biome is considered one of the hottest hotspots. Due to this reason, there are many environmental strategies being developed to ...
Isolation determines patterns of species presence in highly fragmented landscapes
(Wiley-Blackwell, 2011-12-01)
In fragmented landscapes, changes in habitat availability, patch size, shape and isolation may affect survival of local populations. Proposing efficient conservation strategies for such species relies initially on ...
Avian responses to forest fragmentation during the breeding and non-breeding seasons
(Wiley Blackwell Publishing, Inc, 2020-10)
Forest fragmentation represents a threat to several bird species worldwide. Several factors can change across seasons (e.g. bird perception of the landscape, weather conditions, biotic interactions), which can modify the ...
Population variation in patch and party size in muriquis (Brachyteles arachnoides)
(Plenum Publ Corp, 1998-04-01)
We examined the relationship between food patch size and feeding party size with comparative data from two populations of muriquis (Brachyteles arachnoides) in the 37,797-ha forest at the Parque Estadual de Carlos Botelho ...
