Shifts in grasses diversity patterns between two contrasting 40-year climate pe...
Duarte, Maria Cristina; Rocha, Vanézia; Fernández-Palacios, José María; Gomes, Isildo; Neto, Carlos; Costa, José C.; Branquinho, CristinaGrasses are one of the most successful and dispersed plant families worldwide and their environmental and economic values are widely acknowledged. They dominate the landscape of Cabo Verde, the southernmost and driest archipel- ago of Macaronesia, and are relevant natural resources for local populations, but a comprehensive evaluation of their distribution patterns is still lacking. In this study, we aim to eva...

Cardoso, João Francisco; Costa, José C.; Neto, Carlos; Aguiar, Carlos; Bioret, Frederic; Schmit, Tomas; Fonseca, João PauloNo Sudoeste de Angola, na Província do Namibe, em bioclima tropical superior, termotropical, árido, ocorre uma vegetação nano-microfanerofanerofítica formada por uma savana aberta caracterizada pela frequente presença de plantas suculentas. Assim observa-se as seguintes comunidades: 1 Boscio welwitschii-Colophospermetum mopanes: savana micro-nanofanerofítica, em solos alcalinos (pH 7-9) de textura franco-arenos...
Ultrabásicos de Cabeço de Vide
Costa, José C.; Neto, Carlos; Aguiar, Carlos; Flor, António; Pereira, PauloAs rochas ultrabásicas (ou ultramáficas) são relativamente frequentes no Alentejo. Dada a exiguidade dos afloramentos, e em consequência de processos morfogenéticos (e.g., movimento das partículas do solo por ação da gravidade) ou de lavouras e outras operações agrícolas, os produtos da meteorização destas rochas estão, geralmente, misturados com materiais provenientes de solos adjacentes derivados de outras li...

Costa, José C.; Neto, Carlos; Aguiar, Carlos; Capelo, Jorge; Espírito Santo, Dalila; Honrado, João José; Pinto-Gomes, Carlos; Monteiro-Henriques, T.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...
The meaning of mainland Portugal beaches and dunes’ psammophilic plant communit...
Martins, Mónica C.; Neto, Carlos; Costa, José C.Due to their position of interface between the sea and land, the flora and vegetation of coastal beaches and dunes, occupy ecologically extreme, sensitive, unique and valuable habitats. The occurrence of a large number of endemic taxa and specific plant associations endowed with key ecological services and adapted to a stressful and harsh environmental gradient, gives them a high interest for nature conservatio...

Costa, José C.; Monteiro-Henriques, T.; Bellu, Annalisa; Aguiar, CarlosThe mesophilous woods dominated by Quercus faginea subsp. faginea or Acer monspessulanum thriving on neutral to alkaline deep clayish soils have been collected under the alliance Aceri granatensis-Quercion fagineae (Rivas Goday, Rigual & Rivas-Martínez in Rivas Goday, Borja, Esteve, Galiano, Rigual & Rivas-Martínez 1960) Rivas-Martínez 1987. Punctually, woods dominated by Q. faginea subsp. alpestris, Corylus av...
