    This dataset is based on the Atlas of Amphibians and Reptiles of Portugal published by ICNF in 2008. The publication of this document is related to the implementation of the National Strategy for the Conservation of Nature and Biodiversity, whose 5th strategic option concerns development throughout the national territory of specific actions for the conservation of species and habitats, defining as one of the action directives the elaboration of several distribution atlases. The Atlas shows, according to the record of observations made up to the date of its publication, the distribution, in Portugal, of amphibians and reptiles that are autochthonous in the Portuguese territory, and also exotic species existing in the wild: 17 species of amphibians; 30 species of terrestrial reptiles; and 5 species of sea turtles. The original publication presents, for each of the species, a sheet with the characterization of the species and notes on the main threats and measures for its conservation.

  • The Atlas of Shapes includes an illustrative scheme of the shapes subdivided in “Simple Shapes” and “Complex Shapes”. Clicking on a specific shape, users are able to see: the code and the name of the shape, the shape view (e.g., lateral, frontal, etc.) with the corresponding linear dimensions, the biovolume and surface area computational models with all the formulae associated. Clicking again on a specific shape, users will be redirected to all taxa present in the Atlas of Phytoplankton that are characterized by the selected shape. Atlas of shapes and Atlas of phytoplankton are integrated and can be easily joint switching from taxonomic identification to morphological characterization of phytoplankton.

    The Atlas of nesting birds from Portugal makes an inventory of 235 breeding species, from which 221 are native, and, among these, 205 with regular nesting activity. It covers a period from 1999 to 2005. The project "Atlas of the Birds that Nest in Portugal" aimed to know the current distribution of breeding species in Mainland Portugal and in the autonomous regions of Madeira and the Azores and to characterize abundance, when possible, of national populations of these species, during the period of 1999 to 2005. This dataset comprised two layers of information: Directed Census - Distribution data for bird species targeted by directed census, except Aquila adalberti, Aegypius monachus and Pterocles alchata whose location is confidential (includes marginal 10x10 km UTM squares); Other species - distribution data for the remaining species (does not include UTM 10x10 km marginal grids). The project involved the participation of ca. 500 volunteers, more than a dozen professional employees and various work teams in the organization. It is the result of a fundamental partnership with three other entities, namely the SPEA - Portuguese Society for the Study of Birds (a non-governmental association that works for the conservation of birds and their habitats in Portugal and which brings together numerous members interested in this faunal group); the Natural Park of Madeira (PNM) and the Regional Directorate for the Environment of the Azores (DRA), entities responsible for the conservation of wild birds in the autonomous regions.
