The northeastern Atlantic and the Mediterranean Sea share geological histories and display great faunal aYnities. The majority of the Mediterranean species have Atlantic origins, with a few species with tropical aYnities. These include the parrotWsh Sparisoma cretense and the wrasse Thalassoma pavo that are restricted to the subtropical northeastern Atlantic, the Macaronesian archipelagos (Azor...
Climate control centers in each area are diverse and understanding how they relate to the atmospheric components of the Earth's surface contribute to prediction of climate fluctuations. In this study, by using Pearson's correlation and multivariate regression in a thirty-year period (1961-2010), the relationship between widespread rainfall anomalies in entire of Iran west with temperature a...
Taxonomical vs. functional responses of bee communities to fire in two contrasting climatic regions.
1. Valuable insights into mechanisms of community responses to environmental change can be gained by analysing in tandem the variation in functional and taxonomic composition along environmental gradients. 2. We assess the changes in species and functional trait composition (i.e. dominant traits and functional diversity) of diverse bee communities in contrasting fire-driven systems in two clima...
A major focus of invasion biology is understanding the traits associated with introduction success. Most studies assess these traits in the invaded region, while only few compare nonindigenous species to the pool of potential invaders in their native region. We focused on the niche breadth hypothesis, commonly evoked but seldom tested, which states that generalist species are more likely to bec...
The desiccation of the Mediterranean Sea during the Messinian Salinity Crisis 6.0-5.3 million years ago (Ma), caused a major extinction of the marine ichthyofauna of the Mediterranean. This was followed by an abrupt replenishment of the Mediterranean from the Atlantic after the opening of the Strait of Gibraltar. In this study, we combined demographic and phylogeographic approaches using mitoch...
The EU’s Member States bordering the Mediterranean – France, Greece, Italy and Spain have important and often locally significant fisheries sectors, operating in an environment that is characterised by high biological diversity. Despite the existence of an otherwise ‘common’ EU fisheries policy, Mediterranean fisheries have traditionally been subject to separate EU fish stock management measure...
The present study deals with the implementation of an eddy resolving model of the Levantine and Aegean basins and its one-way nesting with a coarse resolution (1/8× 1/8) global Mediterranean general circulation model. The modelling effort is done within the framework of the Mediterranean Forecasting System Pilot Project as an initiative towards real-time forecasting within the eastern Mediterra...
BACKGROUND Systematic reviews can offer policymakers and stakeholders concise, transparent, and relevant evidence pertaining to pressing policy priorities to help inform the decision-making process. The production and the use of systematic reviews are specifically limited in the Eastern Mediterranean region. The extent to which published systematic reviews address policy priorities in the regio...
To investigate the Artemisia vegetation in Isfahan Province, two rangelands of Khorous Galu in the southwest and Ashan in the west of Isfahan were selected. These rangelands are mountainous with semiarid climate. In Khorous galu, 68 species belonging to 50 genera and 24 families were identified. Life forms included hemicryptophytes (39%), therophytes (27.5%), chamaephytes (19%), geophytes (13%)...
