At 00:02 GMT (03:02 local time) on 17 August, 1999 a magnitude 7.4 (Ms) earthquake occurred 100 km east of Istanbul causing extensive destruction. The event was expected and several scientists have published and attempted to publicize the danger. A paper on stress interactions for NW Turkey (J. Geophys. Res. 103 (1998) 24466–24469) concluded that “by combining the stress change map with the map of active faulting, likely locations for the occurrence of future earthquakes can be refined; faults in the Izmit Bay area, the western part of Biga Peninsula, the Saroz Gulf and a part of western Sea of Marmara must be regarded as posing a specific hazard”. An extension of that study is described here. It is shown that the Izmit (1999) earthquake loaded faults both to the east and west of the Izmit rupture. About three months after the Izmit event an M 7.2 earthquake occurred with an epicenter at Duzce extending the Izmit rupture to the east. In the Marmara Sea, west of Izmit, faults have been loaded by between 1 and 5 bar; 5 to 30 % of typical earthquake stress drops in the region suggesting the likelihood of a future event. The risk of a major event on a fault depends not just on stress increases associated with an individual earthquake, but also on the longer-term earthquake history and on tectonic loading. The roles of both are examined over two time periods from 1900 to 1999 and 1700 to 1999. Whatever interpretation we place on the data we conclude that one or two events as great or greater than the recent one is likely to occur within the next few decades near to the northern coast of the Marmara Sea [less ▲]

Face aux importantes perturbations, principalement d’origines anthropiques, qui affectent l’écosystème côtier méditerranéen, il est nécessaire de mettre en place des outils de diagnostic rapides de ces perturbations. Posidonia oceanica (L.) Delile, qui est un des piliers de cet écosystème, a souvent été utilisée pour évaluer l’état de santé du milieu côtier méditerranéen. Cependant, comme son turnover est relativement lent et que cette plante peut accumuler des réserves qui lui permettent, durant des périodes relativement longues, du garder une phénologie stationnaire, malgré des changement environnementaux, il est parfois trop tard lorsqu’elle montre les effets d’une perturbation. Dans ce contexte, il devient nécessaire de trouver des outils de diagnostic précoces de ces perturbations. Dans ce cadre, les modifications des populations épiphytes, qui ont un turnover plus rapide que la plante, apparaissent comme des marqueurs plus précoces de la pollution. Dans ce cadre, nous avons tenté de déterminer si les communautés épiphytes se développant sur des feuilles artificielles imitant les feuilles de posidonies étaient semblables à celles s’installant sur les feuilles naturelles, et ce afin de voir si les feuilles artificielles pouvaient être utilisées comme modèle de feuilles de posidonies dans le cadre d’études d’impact. Les résultats obtenus ont montrés que la colonisation des deux types de feuilles n’était pas similaire. En effet, la densité des épiphytes était beaucoup plus importante à la base des feuilles artificielles qu’à la base des feuilles de posidonies mais la diversité et l’équitabilité calculées pour les grands taxa était plus élevée sur les feuilles naturelles. Cependant, l’étude de la colonisation par les épiphytes réalisée sur toute la longueur de la feuille artificielle a montré une zonation proche de celle normalement rencontrée sur les feuilles matures de posidonies. Ainsi, au début de la colonisation et pour la base des feuilles, les feuilles artificielles ne sont pas de bons modèles des feuilles de posidonies et ne peuvent pas être utilisées dans le cadre d’études d’impact. Cependant, au vu des résultats obtenus pour toute la longueur des feuilles artificielles et des données de la littérature, on ne peut pas exclure que, pour des stades plus avancés de la colonisation, la feuille artificielle soit un bon modèle de la feuille naturelle.

Although human-driven landscape modification is generally characterized by habitat destruction and fragmentation, it may also result in the creation of new habitat patches, providing conditions conducive to spontaneous colonization. In this article, we propose the concept of ‘‘colonization credit’’ (i.e., the number of species yet to colonize a patch, following landscape changes) as a framework to evaluate the success of colonization, in terms of species richness, in new/restored habitats, taking into account the spatial structure of landscapes. The method mirrors similar approaches used to estimate extinction debt in the context of habitat fragmentation, that is, comparisons, between old and new habitat patches, of the relationships among spatial patch metrics and patch species richness. We applied our method to the case of spontaneous colonization of newly created habitat patches suitable for wet heathland plant communities in South Belgium. Colonization credit was estimated for the total species richness, the specialist species richness, and the species richness of three emergent groups (EGs) of specialist species, delineated on the basis of dispersal traits. No significant colonization credit was identified either in patches created 25–55 years ago or in those created within the past 25 years, with the exception of species from our first EG (mostly anemochorous species with long-term persistent seed bank). However, the differential response of species in that first EG could not be explained through their characteristic life history traits. The results of this study are encouraging and suggest that deliberate, directed restoration activities could yield positive developments in a relatively short period of time. [less ▲]
