INTRODUCTION

The progressing and escalating threats posed by invasive alien species in Europe suggest that immediate cooperative, specific planning is necessary if we are to have any chance to halt biodiversity loss. Scientific, technical, political and legal actions need to be put in place urgently in order to diminish the ecological and economic impacts of biological invasions.

In this framework, NEOBIOTA 2012 provides an international high-level forum to incorporate research into decision making processes and management of invasive alien species. NEOBIOTA constitutes an important opportunity to advance the dialogue and strengthen cooperation between the scientific community, conservation agencies, stakeholders, and policy and decision makers.

Researchers, representatives from governmental entities, non-profit organizations, and any person or party involved in biodiversity conservation and natural resource management are invited to participate and share ideas, new results and opinions in the field of biological invasions.

The species introductions shape the vertebrate communities in greater extent in the Mediterranean Basin that in other biodiversity hotspots. Harbouring simpler communities constituted by species evolved under relaxedness competition, Mediterranean islands are especially vulnerable to biological invasions. Determining the origin of such aliens is the first step to develop successful strategies of prevention and minimisation. Reptiles in the Balearic Islands represent a paradigmatic case, with more alien than native species. In this work, we identify the allochthonous status and the putative origin of the snakes Hemorrhois hippocrepis, Malpolon monspessulanus, Macroprotodon mauritanicus, Natrix maura and Rhinechis scalaris by using molecular markers. We also estimate the habitat suitability and anthropic favoring factors for each species using GIS models in an attempt to infer their patterns of invasion and expansion. This information is expected to provide insights on pathways by which these snakes have arrived to the islands and aid preventing new introductions and to implement control measures by policy makers. We assessed the origin of all the snakes sampled using several molecular markers (Cytb, ND4, COI) by putting sequences generated together with those published for the species both in its autochthonous range and in other introduced populations. Results are discussed in the context of the phylogeography of each species and its invasive character. For most of the species molecular data allowed identifying the potential source of the allochthonous population. Finally, we determine the importance of each factor (tree nurseries, human density, climate, land use) through the time for every species. This multi-approach, joining molecular data with ecological modeling together, reveals a promising tool for understanding of the complex invasion process and, hence, supporting conservation planning.
