Remotely sensed indicators and open-access biodiversity data to assess bird diversity patterns in Mediterranean rural landscapes

摘要: Biodiversity monitoring at simultaneously fine spatial resolutions and large extents is needed but limited by operational trade-offs costs. Open-access data may be cost-effective to address those limitations. We test the use of open-access satellite imagery (NDVI texture variables) biodiversity data, assembled from GBIF, investigate relative importance variables habitat extent structure as indicators bird community richness dissimilarity in Alentejo region (Portugal). Results show that, landscape scale, forest better indicated availability tree cover overall than or habitats. Open-land birds also respond structure, namely spectral homogeneity size open-land patches presence perennial vegetation amid herbaceous Moreover, were more important climate geographic distance explain patterns regional scale. Overall, summer imagery, when discernible, particularly suited inform dissimilarity, while spring appears useful richness.
