In this paper we present the results of a geobotanical study carried out on the communities of Cytisus oromediterraneus and Genista cinerascens in Serra da Estrela, two species that in the Central Iberian Peninsula lead the associations Cytiso oromediterranei-Genistetum cinerascentis and Pteridio aquilini-Cytisetum oromediterranei. The prime objective was to describe their geographical and main ecological featu...

As result of several field trips following PhD researches in Marianic-Monchiquensean Sector, we describe a new broomland association named Genistetum triachanthi-polyanthi as a thermomediterranean, oceanic and sub-humid to humid, schistose association. The 26 relevés analysis, combining phytosociologic methodology with hierarchical cluster analysis (Ward's Hierarchical Clustering, based on Bray-Curtis distance)...
Dentro de los indicadores ambientales establecidos en la IDE OTALEX C, se encuentran indicadores climáticos. El último periodo de estos que ha sido estudiado se extiende desde 1971 a 2000 con datos de 99 estaciones termopluviométricas. Se han elaborado mapas de temperaturas y precipitaciones, calculándose además el Índice de continentalidad (Ic), el Índice ombrotérmico (Io), el Índice de aridez (Ia), la evapotr...
Se propone una metodología para la ampliación de la cartografía de usos existente hasta el momento, mediante el análisis de imágenes satelitales, con algoritmos basados en la identificación de objetos (OBIA). El objeto de estudio es analizar las dinámicas territoriales de las Vegas Altas del Guadiana, partiendo de la cartografía Corine Land Cover y plantear un procedimiento que permita ampliar los años de análi...
La cartografía integrada del medio natural está basada en la toma en consideración de factores del medio, permitiendo identificar factores ecológicos relevantes en relación a gradientes edáficos. Estos factores son la base para la elaboración de unidades edafoambientales. Hasta el momento, el concepto de diversidad ha sido utilizado ampliamente en biología, existiendo escasos antecedentes tanto en la literatura...
O Livro Verde dos Montados apresenta diversos objectivos que se interligam: Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma oportunidade de caracterizar o sistema tendo em conta as suas vár...
Extremadura, in Spain, and Alentejo and Centro, in Portugal, are tree regions belonging to different countries but with several common interests. They are continuous border areas that share similar ecological, socioeconomic and environmental characteristics. The cooperation between these territories which promotes the collaboration and exchange of information between both sides of the Spanish-Portuguese frontie...
This work was developed as part of PhD research devoted to the flora and vegetation of the Caldeirão and Monchique mountains that aims to identify the vegetation climatophilous series and use them as an environmental diagnosis of Algarve administrative province phyto-ecological subregions. Biogeographic and bioclimatic considerations are presented, as well as the study area pedological and lithological characte...
This paper re-examines the Rhamno-Prunetea class in the centre and south of the Iberian Peninsula, especially in Andalusia. The paper also deals with the alliances Pruno-Rubion ulmifolii Lonicero-Berberidion hispanicae in the south of the Iberian Peninsula, and Berberidion vulgaris (Berberidenion seroi) in the area of Cuenca. Our analysis of 225 relevés arranged in 22 phytosociological tables helped us to re-or...
