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...

Vascular plant communities in Portugal (Continental, the Azores and Madeira)

In this paper 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 classes, are also mentioned, as auxilliary ranks. For the higher syntaxa d...

A global view on the riparian forests with Salix neotricha and Populus alba in ...

Forests dominated by Salix neotricha, and Populus alba found along the mesoeutrophic rivers in the Iberian Peninsula, were studied. We discuss the floristic circumscription, chorology, and community segregation based on the available releve´s of all Iberian riparian communities included in Populenion albae. Eleven formerly described communities were analyzed and due to original floristic combination, habitat fe...

Geographic variation among iberian communities of the exotic halophyte Cotula c...

The exotic annual forb Cotula coronopifolia has locally invaded salt marsh communities naturally dominated by Spergularia marina along large parts of the Iberian coastline. While the floristic composition of C. coronopifolia dominated communities on the Atlantic coast of northern Portugal has already been described, this information was missing for the southern part of the country. We carried out a phytosociolo...

Os sobreirais da bacia ceno-antropozóica do Tejo (Província Lusitano-Andaluza L...

Os sobreirais da bacia ceno-antropozóica do Tejo (Província Lusitano-Andaluza Litoral), Portugal. A análise das características das formações litológicas de enchimento da bacia do Tejo, com idades que vão do Miocénico ao Plistocénico, permitiu compreender melhor o mosaico de sobreirais potenciais, pertencentes respectivamente ao Oleo sylvestris-Quercetum suberis e ao Asparago apphylli-Quercetum suberis. A compo...

A methodological approach to potential vegetation modeling using GIS techniques...

An attempt to obtain a consistent spatial model of natural potential vegetation (NPV) for the mainland Portuguese territory is reported. Spatial modeling procedures performed in a Geographic Information System (GIS) environment, aimed to operationalize phytosociological expert-knowledge about the putative distribution of potential zona1 forest communities dominam in the Portuguese continental territories. The p...

Phytosociologic associations and Natura 2000 habitats of Portuguese coastal san...

The portuguese coastline is quite long and the littoral ecosystems are of the outmost importance in the context of the national flora and vegetation. The diversity of vegetation types and the endemicity of their flora justify the attention paid to coastal habitats in the implementation of the Natura 2000 network. In this paper we present a synatoxonomical revision of the phanerophytic, chamaephytic and hemicryp...

The landscape and plant communities of Serra da Arrábida

The field trip takes place in the biogeographic territories of the Sadensean-Dividing Portuguese Subprovince (Coastal Lusitan- Andalusian Province, Mediterranean Region), throughout the upper thermomediterranean thermotype and subhumid ombrotype.
