Impact of soil texture on plant communities of Raphanus raphanistrum L.
Cano-Ortiz, Ana; Del Río González, Sara; Pinto-Gomes, CarlosOur soil study of the chromic soils located in the strip of land between Sierra Morena and the Guadalquivir Valley reveals a pH-value close to neutral in 25 samples. The pH-values are close to 5.5 only in the samples taken from the arenosols of the granitic batholith of Los Pedroches. However, it is the percentage of clay, sand and silt that explains the occurrence of grassland dominated by Raphanus raphanistru...
The Algarve climatophilous vegetation series – Portugal: a base document to the...
Quinto-Canas, Ricardo; Vila-Viçosa, Carlos; Paiva-Ferreira, Rodrigo; Cano-Ortiz, Ana; Pinto-Gomes, CarlosThis 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...
Current state of the Prunetalia spinosae communities in the centre and south of...
Cano-Ortiz, Ana; Pinto-Gomes, Carlos; Quinto-Canas, Ricardo; Vila-Viçosa, Carlos; Rodríguez-Torres, Alfonso; Redondo, ManuelaThis 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...

Pinto-Gomes, Carlos; Cano-Ortiz, Ana; Quinto-Canas, Ricardo; Vila-Viçosa, Carlos; Lombardo, Mª C. MartínezThe statistical and phytosociological study of 255 relevés taken in the south-west of the Iberian Peninsula and made up of our own samples and previous publications reveals how close these relevés, previously ascribed to different syntaxa, really are. Our re-arrangement of the data leads us to propose for the territory the 15 associations already published and three new ones, namely: Genisto floridae-Adenocarpe...
A new Erica lusitanica Rudolphi heathland association to the Iberian south-west
Vila-Viçosa, Carlos; Quinto-Canas, Ricardo; Mendes, Paula; Cano-Ortíz, Ana; Rosa-Pinto, José; Pinto-Gomes, CarlosAs result of several field trips following doctoral research in Marianic-Monchiquensean Sector, we describe a new heathland named Lavandulo viridis-Ericetum lusitanici ass nova hoc loco (Genistion micrantho-anglicae, Rivas- Martínez 1979) as a thermomediterranean to lower mesomediterranean, upper dry to humid, schistose association. The analysis of 11 relevés, following Braun-Blanquet methodology shows the flor...
A contribute to the knowledge of the climatophilous cork-oak woodlands from Ibe...
QUINTO-CANAS, Ricardo; VILA-VIÇOSA, Carlos; MEIRELES, Catarina; PAIVA-FERREIRA, Rodrigo; MARTÍNEZ-LOMBARDO, Maria; CANO-ORTIZ, Ana; PINTO-GOMES, CarlosThis work results as an in-depth study of climatophilous cork-oak woodlands from Iberian southwest, by the necessity to profound the knowledge of this West-Mediterrenean vegetal formations, particularly in the most atlantic territories. Accordingly, we describe a new cork-oak forest association subhumid to humid, thermomediterranean, siliceous, from « Marianico-Monchiquense » sector as a climatophilous serie, n...
Contribution to the study of the Taenianthero-Aegilopion geniculatae alliance i...
CANO-ORTIZ, Ana; PINTO-GOMES, Carlos; CANO-CARMONA, EusébioThis paper deals with the study of Taeniathero-Aegilopion geniculatae subnitrophilous communities found in the centre and south of Portugal, particularly in abandoned olive groves with vegetal cover. The edaphic and phytosociological study reveals that these pasturelands thrive on neutro-basic soils. In the corresponding dendrogram and in the co-location network, their peculiar floristic composition and, in par...
Determination of the nutritional state of soils by means of the phytosociologic...
Cano-Ortiz, Ana; Pinto-Gomes, Carlos; Esteban, Francisco; Cano, EusébioThe paper deals with the nitrophilous Hordeum leporinum pasturelands peculiar to the olive groves of Jaén, Spain. The study first selects physiognomically homogeneous land plots and subsequently samples are taken where the relevant species is dominant. Simultaneously, an edaphic sample is taken and the different edaphic parameters are analysed. By means of phytosociological and statistical methods (cluster anal...
Biodiversity of Hordeion leporini in Portugal: a phytosociological and edaphic ...
CANO-ORTIZ, Ana; PINTO-GOMES, Carlos; ESTEBAN, F.J.; RODRIGUEZ-TORRES, A.; GONI, J.; de la HAZA, I.; CANO CARMONA, E.This study reveals the occurrence of Phalaris coerulescens communities both in Portugal and the south of Andalusia (Spain). These grasslands present a variable cover ratio and have an average dominant vegetation size of about 100 cm. They tend to occur in river beds and in places which are sometimes water-logged, with a certain amount of organic matter inducing the occurrence of nitrophilous companion species. ...
