Abstract The Hybrid Single-Particle Lagrangian Integrated Trajectories (HYSPLIT) model has been applied to calculate the spatial and temporal distributions of dust originating from North Africa. The model has been configured to forecast hourly particulate matter ≤10 μm (PM10) dust concentrations focusing on the impacts over the southern Iberian Peninsula. Two full years (2008 and 2009) have been simulated and compared against surface background measurement sites. A statistical analysis using discrete and categorical evaluations is presented. The model is capable of simulating the occurrence of Saharan dust episodes as observed at the measurement stations and captures the generally higher levels observed in eastern Andalusia, Spain, with respect to the western Andalusia station. But the simulation tends to underpredict the magnitude of the dust concentration peaks. The model has also been qualitatively compared with satellite data, showing generally good agreement in the spatial distribution of the dust column.

We assembled genome-wide data from 271 ancient Iberians, of whom 176 are from the largely unsampled period after 2000 BCE, thereby providing a high-resolution time transect of the Iberian Peninsula. We document high genetic substructure between northwestern and southeastern hunter-gatherers before the spread of farming. We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia’s ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry. We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European–speaking regions but also into non-Indo-European–speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia. Additionally, we document how, beginning at least in the Roman period, the ancestry of the peninsula was transformed by gene flow from North Africa and the eastern Mediterranean.

AbstractRecent molecular studies indicate that Podarcis wall lizards occurring in the southern region of the Iberian Peninsula and in North Africa, from south Morocco to eastern Tunisia, constitute a monophyletic group composed of several highly differentiated forms that appear to be incipient species. However, Algerian populations, which are geographically intermediate, have not been investigated so far. In this study we determine the levels of genetic variability between Algerian populations and other North African populations, using a more extensive sampling scheme covering most of the distribution range in this area. Our results show that North African Podarcis present high genetic diversity, comprising at least five highly divergent lineages. Two of these lineages were only detected in Algeria, which harbours most of the genetic diversity found within Podarcis from North Africa.

Declared national park since 2003 in the province of Naâma in Algeria, it covers an area of around  24 400 hectares. Djebel Aissa national park offers particularly favorables conditions for the development of important floristic diversity with endemic and / or rare taxa.The inventory of the plant biodiversity in the park revealed the existence of 379 taxa belonging to 52 families and 233 genera. An important endemics number has recorded:  24 North Africa, 23 Algerian-Moroccan,4 North Africa and Iberian Peninsula, 5 Algerian, 6 Saharan, 1 Algerian-Tunisian, 1 ibero-algero-Moroccan and 2 ibero –Moroccan. 65 species were reported as rare or very rare, including 15 quite rare species, 36 rare species, 12 very rare species and 2 extremely rare species.

RESUME. Diversité floristique des suberaies du Parc National de Tlemcen (Algérie). L’analyse de la diversité floristique des forêts de Hafir Zariffet a révélé l’existence de 211 taxons appartenant à 65 familles et 164 genres. Le nombre de taxons endémiques et/ou rares inventoriés comporte: 1 endémique algérien,7 algéro-marocains, 11 ibéro-algéro-marocains, 7 sont endémiques d’Afrique du Nord et 11 sont des endémiques d’Afrique du Nord et de la Péninsule ibérique. Le nombre des taxons rares s’élève à 26 dont 9 sont en même temps rares est menacés. Des efforts urgents de protection doivent êtres consentis pour préserver le chêne liège ainsi que les espèces endémiques qui lui sont inféodées.Mots clés. Subéraies, inventaire, diversité, Parc National de Tlemcen, Algérie.SUMMARY. Flora diversity of cork oak forest in the National Park of Tlemcen (Algeria). The analysis of the floristic diversity of forest massif “Hafir-Zariffet” in the Tlemcen National Park has revealed the existence of 211 taxa which belong to 65 families and 164 genera. The number of taxa endemic and/or rare includes: 1 endemic algerian, 7 algero-moroccan, 11 ibero-algero-moroccan, 7 are endemic in North Africa and 11 are endemic in Iberian Peninsula and North Africa. The number of rare taxa is 26, 9 are at the same time threatened. Urgent efforts are required to preserve the cork oak as well as endemic species confined to it.Key words. Cork oak forest, inventory, diversity, National Park of Tlemcen, Algeria.
