Sobre mètodes senzills d'anàlisi corològica i la seva aplicació a un cas concret: l'estudi de l'herpetofauna del Pirineu aragonès Authors Joan-Pau Martínez-Rica Abstract This paper has the purpose of applying some simple procedures of analysis to the study of the spatial distribution of the herpetofauna from the High Aragon. The work is based on a set of 1.255 data. Temporal distribution of these data throughout the year presents a great diversity according to the species considered; in most species mean activity lies at the end of the spring, or at the beginning of the summer. Mean activity comes later in Reptilia than in Amphibia. Almost all species present distributions of contagious type; this is consequence of an uneven prospective effort. The country is very poorly prospected, but it is still among the most thoroughly known zones in Spain. Density maps of different species reveal the prevailing influence of orography; it is also possible to detect the influence of an eastwest gradient of humidity in the distribution of many species. Mean altitude of data for each species gives a good criterion to discriminate the mountain forms from the plains forms. On the average, the mean points of distribution of localities for each species lie more at north for the former than for the later. Caudata present also a mean altitude higher then other taxa.
