The scrubland of limestone-derived decarbonated soils of the western Iberian Pe...

In the present article, the proposal of a new suballiance, Lavandulo luisieri-Cistenion albidi, is presented, constituted by chamaephytic and nanophanerophytic communities in eroded decarbonated soils derived from limestones (leptosols, chromic luvisols and cambisols) in the dry to lower hyperhumid, thermo-mesomediterranean bioclimatic levels. It is distributed throughout the western Iberian Peninsula in the Co...

Tipologia dos lameiros de Trás-os-Montes

Os lameiros são pastagens seminaturais de flora indígena dependentes de uma gestão antrópica por pastoreio e/ou corte. Nas regiões de clima mediterrânico ou submediterrânico são constituídos por mosaicos complexos de comunidades vegetais. Os trabalhos clássicos do Eng.o Agrón. A. N. Teles nas décadas de 1960 e 1970 demonstraram que a maior parte da biomassa dos lameiros é produzida em comunidades de Arrhenather...

Environmental and landscape rehabilitation: case study for fresh stone treatmen...

The construction of big dams usually cause a severe environmental change at a local level, producing a considerable visual impact that must be remedied and the disturbed area must be rehabilitated and recovered, approaching the landscape prior to the dam construction. In this work, several assays were tested, with the purpose of finding a treatment for fresh cut granite that could be used as a general rock trea...

Conservation Management of EU Priority Habitats after Collapse of Traditional P...

Agricultural abandonment is a major driver of change in rural landscapes. Assumed to provide beneficial results to the environment and the conservation of biota, rural abandonment triggers landscape and biotic homogenization and loss of valuable species and habitats. This article focuses on the ecological effects and conservation challenges of shifts in extensive grazing regimes on marginal pastureland of Medit...

Bioclimatological mapping tackling uncertainty propagation: application to main...

We present a bioclimatological diagnosis of mainland Portugal, namely the thermotype and ombrotype maps following Rivas-Martínez’s worldwide bioclimatic classi$cation system. In order to obtain this diagnosis, we produced maps of bioclimatological indices using, as base data, geostatistical interpolations of air temperature and precipitation.We performed uncertainty propagation obtaining uncertainty measures fo...

O novo catálogo da vegetação portuguesa (Continente, Açores e Madeira): descriç...

In this work we propose a syntaxonomic scheme, according to the Code of Phytosociological Nomenclature for the vegetation of Portugal: continental and the Azores and Madeira archipelagos. The scheme encompasses 827 associations (4 communities), 245 alliances, 116 orders, and 64 vegetation classes. The 58 suballiances, 2 suborders and 4 subclasses, are also mentioned, as auxiliary ranks. For the higher syntaxa d...

New contributions on flora and vegetation of northeastern Portugal ultramafic o...

In this work we present some syntaxonomic novelties on the vegetation of the referred ultramafic outcrops focused on three new associations: Jonopsidio abulensis-Sedetum maireani, Armerio daveaui-Agrostietum castellanae and Seseli peixotoani- Avenuletum lusitanicae; in addition, a new nomenclatural combination of an endemic taxon from the Morais massif (Armeria langei subsp. marizii) is proposed. We also clarif...
