(Seitzinger et al.2005; Mayorga et al.2010). The coastline length and river catchment surface areas were extracted using a GIS from the attributes of the shapefile of the GlobalNEWS product while the river discharge corresponded to those calculated for the year 2000 by Fekete et al. (2010)....
The estimated home range and core area data were transferred to QGIS 3.16 (QGIS Development Team) as a shapefile to extract each ecological factor value (except for climatic factors) corresponding to each home range and core area using zonal statistics. Topographic factors as independent variables....
