Geoclimatic regions were identified using a PCA.\n\t\t\t\t\t\tIndividual habitat suitability (HS) models for 23 amphibians and 35 reptiles\n\t\t\t\t\t\tat 10 \u00d7 10 km scale were calculated with ENFA, using 12 environmental\n\t\t\t\t\t\tfactors established with Remote Sensing (RS) techniques. The species\n\t\t\t\t\t\tpresence proportion in each geoclimatic region was calculated through a\n\t\t\t\t\t\tcross-tabulation between each potential occurrence model and the geoclimatic\n\t\t\t\t\t\tregions. Species chorotypes were determined through Hierarchical Cluster\n\t\t\t\t\t\tAnalysis using Jaccard's index as association measure and by the analysis of\n\t\t\t\t\t\tmarginality and tolerance factors from individual HS models. Predicted\n\t\t\t\t\t\tspecies density maps were calculated for each geoclimatic region. Probable\n\t\t\t\t\t\tunder-sampled areas were estimated through differences between the predicted\n\t\t\t\t\t\tspecies density maps and observed (Gap analysis). The selected PCA\n\t\t\t\t\t\tcomponents divided the Iberian Peninsula in two major geoclimatic regions\n\t\t\t\t\t\tlargely corresponding to the Atlantic and Mediterranean climates. The\n\t\t\t\t\t\tJaccard's index clustered herptiles in two main taxonomic groups, with\n\t\t\t\t\t\tdistribution similar to the Atlantic and Mediterranean geoclimatic regions\n\t\t\t\t\t\t(7 amphibian + 13 reptile species in three Atlantic subgroups and 16\n\t\t\t\t\t\tamphibian + 22 reptile species in four Mediterranean subgroups). Marginality\n\t\t\t\t\t\tand tolerance factor scores identified species groups of herptile\n\t\t\t\t\t\tspecialists and generalists. The highest observed and predicted species\n\t\t\t\t\t\tdensity areas were broadly located in identical regions. Predicted gaps are\n\t\t\t\t\t\tlocated in north-western, north-east and central Iberia. RS is a useful tool\n\t\t\t\t\t\tfor biogeographical studies, as it provides consistent environmental data\n\t\t\t\t\t\tfrom large areas with high accuracy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1163\/156853809788201207","type":"journal-article","created":{"date-parts":[[2009,5,4]],"date-time":"2009-05-04T19:28:24Z","timestamp":1241465304000},"page":"185-206","source":"Crossref","is-referenced-by-count":72,"title":["Biogeographical patterns derived from remote sensing variables: the amphibians and reptiles of the Iberian Peninsula"],"prefix":"10.1163","volume":"30","author":[{"family":"Sillero","sequence":"first","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o em Ci\u00eancias Geo-Espaciais (CICGE) da Universidade do Porto, Departamento de Matem\u00e1tica Aplicada, R.
