Area-sensitive forest birds move extensively among forest patches
Habitat fragmentation is thought to create a barrier to individual movements particularly for area-sensitive species which, by definition, prefer to breed in large tracts of forest. For two breeding seasons, we radio-tracked an area-sensitive species, the scarlet tanager Piranga olivacea, in a fragmented landscape in northeastern PA. We found that scarlet tanagers made extensive and frequent mo...

15 صفحه اولUse of Wildlife Tree Patches by Forest Birds in the Sub-Boreal Spruce (SBS) Zone
Many wildlife species are dependent on habitat attributes within forest stands such as large live trees, standing dead trees, fallen logs, and understory shrubs. Standing dead trees (snags) are especially important because they are used by many species, such as bats, woodpeckers, and furbearers, for feeding and/or nesting. Forest harvesting and silvicultural practices can eliminate or significa...
متن کاملDetecting and Modelling the Trend of Change in the Forest Land Use in Garasu Watershed Area Using Landscape Metrics
Detecting, predicting and quantifying the trends of landscape pattern change in the forests of Gharasu watershed area are necessary so as to assess the crises or prevent them. To this aim, the land use maps belonging to the years 1987, 2002 and 2018 were classified through the maximum likelihood method, and the forest area changes were estimated. Then, through the Geomod model and the forest ch...
