Habitat fragmentation is characterised by reducing a continuous vegetation area in isolated patches. The objective was to evaluate if there process of or habitat loss the Chapada Diamantina and report first impressions on how local biodiversity affected. We used Geoprocessing techniques elaborated map cover land use with Sentinel satellite images. also QGIS 3.10, visual analysis, photo interpre...

Habitat loss and climate change pose a double jeopardy for many threatened taxa, making the identification of optimal habitat for the future a conservation priority. Using a case study of the endangered Bornean orang-utan, we identify environmental refuges by integrating bioclimatic models with projected deforestation and oil-palm agriculture suitability from the 1950s to 2080s. We coupled a ma...
