Abstract Helianthemetea guttati communities are pioneer spring and early summer ephemeral grasslands, dominated by non-nitrophilous therophytes. In Continental Portugal, these communities have not yet been fully investigated, and thus the objectives of the present study are: (1) to identify community types in therophytic grasslands; (2) to recognize those communities that configure the European priority habitat 6220* (pseudo-steppe with grasses and annuals); (3) to establish environmental… 
Early spring ephemeral therophytic non-nitrophilous grasslands as a habitat of various species of romulea in the southern balkans
Abstract The work deals with habitats of Romulea bulbocodium and Romulea linaresii ssp. graeca in the southern Balkans. Both species appear in early spring ephemeral therophytic non-nitrophilous
Rapid Characterisation of Vegetation Structure to Predict Refugia and Climate Change Impacts across a Global Biodiversity Hotspot
The LiDAR-based mapping approach presented enables the integration of site-based biotic assessment with structural vegetation types for the rapid delineation and prioritization of key refugia.
Species–area relationships and minimum area in citrus grove weed communities
Field surveys were carried out in the Catania plain (eastern Sicily, Italy) on winter–spring weed communities in citrus groves, an economical and traditional crop of the Mediterranean area. The aim
Investigating reproductive incompatibility barriers in a Mediterranean rockrose (Cistus ladanifer)
It is argued that, in contrast to the results of its sister species, the highly polymorphic C. ladanifer possesses an extremely stable SI system but a weak reproductive barrier between varieties.
Plant Biosystems-An International Journal Dealing with all Aspects of Plant Biology : Official Journal of the Societa Botanica Italiana
Cistus ladanifer L. (Cistaceae) is a shrubby species, primarily found as a dominant species of the Mediterranean evergreen scrub. Intervarietal (var. ladanifer and var. maculatus) cross compatibility
Conservation status of habitats (Directive 92/43 EEC) of coastal and low hill belts in a Mediterranean biodiversity hot spot (Gargano – Italy)
The work reports an assessment of the presence and conservation status of the habitats according to the 92/43/EEC Directive of Gargano coastal and low hill belts, their relationships with plant communities, threatened species, phytoclimatology, threats, and suggestions for management purposes.
Long-term cropland abandonment does not lead per se to the recovery of semi-natural herb communities deemed habitats of community interest - On-line supplement
It is found that topographic and soil conditions drive species assemblage in pastures after crop abandonment, but that long-term abandonment does not lead per se to the recovery of the semi-natural grassland communities deemed worthy of conservation in the EEC Directive.


Floristic composition and spatial distribution assessment of montane mesophilous grasslands in the central Apennines, Italy: A multi-scale and diachronic approach
Abstract Evaluation of past land use offers valuable information in seeking to understand the distribution patterns of plant communities, insofar as such activity may have altered soil features,
The ecological significance of annuals on a Mediterranean grassland (Mt Ventoux, France)
A study was carried out on a Mediterranean limestone grassland to search for the ecological significance of the occurrence of annuals. In the studied grassland, most of annuals are concentrated in
Cynosurion cristati grasslands in the central Apennines (Tyrrhenian sector): A phytosociological survey in the Lepini and Prenestini mountains
Abstract Cynosurion cristati grasslands are semi‐natural habitats that have developed on mesotrophic soils with a good water supply and are found from the basal up to the mountain vegetation belts.
Biogeography of the Baetic ranges (SE Spain): A historical approach using cluster and parsimony analyses of endemic dolomitophytes
This paper deals with the biogeographical relations between the dolomitophilous flora of the Baetic ranges and the most interesting relations were revealed by means of two complementary strategies: Cluster Analysis and PAE.
Syntaxonomical checklist of vascular plant communities of Spain and Portugal to association level
This paper is a catalogue of all syntaxa from class to association ever described and recognized in Spain and Portugal (Iberian Peninsula, Balearic, Madeira, Azorean and Canary Islands), according
Modulation of diversity by grazing and mowing in native tallgrass prairie
Mowing or the reestablishment of grazing in anthropogenically stressed grasslands enhanced biodiversity, particularly on burned and fertilized treatments.
Environmental control and spatial structure in ecological communities: an example using oribatid mites (Acari, Oribatei)
We have recently proposed to use partial canonical ordinations to partition the variation of species abundance data into four additive components: environmental at a local scale, the spatial
Climate change and grasslands through the ages: an overview
It is predicted that C4-grasses, which are already present in southern Europe, will further expand but that, in the short term, land abandonment will have much more deleterious effects than temperature change due to increased wild fires, loss of biodiversity and desertification.
Spatial and environmental components of variation in the distribution patterns of subarctic plant species at Kevo, N Finland - A case study at the meso-scale level
This study presents a quantitative partitioning of the total variance in the patterns of occurrence of 231 vascular plant taxa in 362 1 x 1 km grids in the Kevo Nature Reserve into four independent
