Última Biogeography and ecology of southern Portuguese butterflies and burnets (Lepidoptera) Naturalis Schmitt, T.. Biogeography and ecology of southern Portuguese butterflies and burnets (Lepidoptera) During several visits to the western part of the Algarve (southern Portugal), the author mapped the butterflies and burnets of this region. In total, I observed 58 butterfly species (51 Papilionoidea, 7 Hesperiidae) and 6 Zygaenidae during my observations in spring and summer. More than 80% of the species are Palaearctic faunal elements, three species are considered Holarctic, three are Nearctic and four are Palaeotropic. Around 75% of the Palaearctic species are Mediterranean faunal elements. Within the Palaearctic group, the 23 species belonging uniquely to the Atlanto- Mediterranean faunal type are by far the largest group. Siberian elements are lacking. Thus, the...

This work presents an entropy approach to disaggregate agricultural data at a local level. It comprises two different steps. In a first one, an information prior at disaggregated level based on experts’ opinions, available cartography of land use and biophysical data is created. In a second step, it’s used a minimum cross entropy process in order to manage these information inputs and to guaranty a solution compatible with all the different restrictions. The model was applied to the region of Algarve in the year of 1999, in order to disaggregate the data at the pixel and county level. Results show that the model was able to provide some satisfactory results since the estimated values obtained for the different areas revealed a good approximation to the...
