Contrasting water strategies of two Mediterranean shrubs of limited distribution: uncertain future under a drier climate.

Contrasting water strategies of two Mediterranean shrubs of limited distribution : 1 uncertain future under a drier climate

Contrasting growth changes in two dominant species of a Mediterranean shrubland submitted to experimental drought and warming.

BACKGROUND AND AIMS Climate projections predict drier and warmer conditions in the Mediterranean basin in the next decades. The possibility of such climatic changes modifying the growth of two Mediterranean species, Erica multiflora and Globularia alypum, which are common components of Mediterranean shrublands, was assessed. METHODS A field experiment was performed from March 1999 to March 20...

Species distribution modelling of invasive alien species; Pterois miles for current distribution and future suitable habitats

The present study aims to predict the potential geographic distribution and future expansion of invasive alien lionfish (Pterois miles) with ecological niche modelling along the Mediterranean Sea. The primary data consisted of occurrence points of P. miles in the Mediterranean and marine climatic data layers were collected from global databases. All the used models run 100% su...

Canopy vs. soil effects of shrubs facilitating tree seedlings in Mediterranean montane ecosystems

Question: Is the facilitative effect of nurse shrubs on early recruitment of trees mediated by a ‘canopy effect’ (microclimate amelioration and protection from herbivores), a ‘soil effect’ (modification of soil properties), or both? Location: Two successional montane shrublands at the Sierra Nevada Protected Area, SE Spain. Method: Seedlings of Quercus and Pinus species were planted in four exp...

Water stress tolerance of shrubs in Mediterranean-type climate regions: Convergence of fynbos and succulent karoo communities with California shrub communities.

Mediterranean-type climate regions are highly biodiverse and predicted to be particularly sensitive to climate change. Shrubs of the mediterranean-type climate region of South Africa are highly threatened, and their response to water stress has been comparatively little studied. Resistance to water stress induced xylem cavitation (P(50)) and xylem specific hydraulic conductivity (K(s)) were mea...
