Mapa de series, geoseries y geopermaseries de vegetación de España[Memoria del mapa de vegetación potencial de España]. Parte I. [Salvador Rivas Martínez y colaboradores]

Résumé

The "Mapa de Series, geoseries y geopermaseries de vegetación de España, 2007" is a new conceptual and cartographic approach to the potential vegetation in Spain interpreted by means of the dynamic-catenal phytosociology (landscape phytosociology). It can be considered as an extended and up to day version of the "Mapa de series de vegetación de España, 1:4000.000" published in 1987 (ICONA, Serie Técnica: 3-208). The wide report is composed of six parts, being the last one, the cartographic, independent and corresponding to the potential vegetation maps (see the general index of the work). In the first part published now, Itinera Geobot. 17: 5-420. 2007, the concepts and essential units on Bioclimatology, Biogeography and Geobotany are presented in a concise way. In the chapter about the Bioclimatology, the parameters, indexes and bioclimatic units of the classification by Rivas-Martínez are presented in detail, and beside this, many climatic and bioclimatic data of 928 localities from peninsular and insular Spain are presented in a final subchapter. In the chapter about the Biogeography, there is an account of the typological approaches at regional, provincial and subprovincial level of the Earth, of Africa and Europe. The biogeographical typology of Spain and Portugal, proposed by Rivas-Martínez and coauthors in several occasions, is exposed widely to distrital level, and a concise and short geographic delimitation is offered, being its cartographic expression published in the chapter 9 of the "anexo cartográfico" (part 5). At the end of this chapter, there are also enumerated other biogeographic, fitogeographic and physiographic typologies on several peninsular and insular territories of Spain and Portugal: Alcaraz & al. (1991), J. C. Costa & al. (1999) and O. Bolòs & al. (2005). The chapter devoted to the Geobotany begins with a detailed exposition of the basics of the dynamic-catenal Phytosociology, with special attention to the cartographic units being treated: vegetation series, vegetation geoseries and vegetation geopermaseries. Then, the morphological aspects and the edaphic factors are reported. And, at last there is a synopsis of some old physiognomic-ecological classifications, which are somewhat useful at global level: Diels (1908) Brockmann-Jerosh & Rübel (1912), Huguet del Villar (1929) and Ellenberg & Mueller Dombois (1967).
