The causal variables were chosen to explain changes in the area and intensity of the edge effect per vegetation class.
Edge Effect on the Arboreal Foliage-gleaning Insectivore Foraging Guild: The RDA biplot showed that the arboreal foliage-gleaning insectivores selected young stands of trees with a diameter between 10 and 20 cm dbh.
Abrupt habitat edges can have a variety of negative and positive influences (edge effects) on wildlife populations, community dynamics, and ecological processes (e.g, Laurance and Yensen, 1991; Murcia, 1995).
In order to test the influence of both spatial variables in the model, we fitted individual models exclusively with the spatial mean trend surface (Eqn 2) and the edge effect distance (Eqn 3):
The proposed approach removes Gaussian noise in the frequency domain and then uses linear guided filtering to further enhance the image recovery, resulting in better denoising and edge effects. As color images display more detailed textures, this filtering overcomes the gradient inversion effect in the edge regions.
Edge effect in the environmental variables: air temperature, relative humidity and photosynthetically active radiation (PAR), along transects of 70 m from the matrix to the interior of P.
Smaller fragments are more degraded as a result of environmental damage that the edge effect leads to plant species.
1978) and to compensate for the "edge effect": at least some sampled individuals have home ranges that extend beyond the edges of the sampling grid, but they are counted as if they reside only within the trapping grid (Dice 1938).
Larger mammals are generally more sensitive to the edge and have larger edge effect distances (Benitez-Lopez et al.
