Where do adaptive shifts occur during invasion? A multidisciplinary approach to unravelling cold adaptation in a tropical ant species invading the Mediterranean area
- Evolution may improve the invasiveness of populations, but it often remains unclear whether key adaptation events occur after introduction into the recipient habitat (i.e. post-introduction adaptation scenario), or before introduction within the native range (i.e. prior-adaptation scenario) or at a primary site of invasion (i.e. bridgehead scenario). We used a multidisciplinary approach to determine which of these three scenarios underlies the invasion of the tropical ant Wasmannia auropunctata in a Mediterranean region (i.e. Israel). Species distribution models (SDM), phylogeographical analyses at a broad geographical scale and laboratory experiments on appropriate native and invasive populations indicated that Israeli populations followed an invasion scenario in which adaptation to cold occurred at the southern limit of the native range before dispersal to Israel. We discuss the usefulness of combining SDM, genetic and experimental approaches for unambiguous determination of eco-evolutionary invasion scenarios.

Terrestrial mammals as biostratigraphic indicators in upper Paleocene-lower Eocene marine deposits of the southern North Sea Basin
- Teeth of terrestrial mammals found in shallow marine deposits of the late Paleocene and early Eocene in the southern North Sea Basin (Belgium, northern France and southeastern England) have been used as biostratigraphic indicators. Analyses indicate that the age of the continental Walbeck mammal fauna (Germany) is close to that of the Upper Selandian Heers Formation of Belgium (NP4-5). The MP6 referencelevel of Cernay (France) is probably correlated with the lower part of NP9 (late Thanetian). The MP7 – MP8 + 9 intermediate faunas of Meudon and Pourcy could be partly equivalent in age to Biochron NP10. The MP8 + 9 reference-level of Avenay corresponds to the upper part of the London Clay and Kortrijk Formations, which are of late middle Ypresian age (lower NP12), or to the lower part of the Wittering and Tielt Formations, which are dated early late Ypresian (middle NP12). The MP10 Grauves and Prémontré faunas (France) are correlated with the NP13 Upper Wittering Formation. The taphonomy of terrestrial mammals discovered in marine deposits indicates several origins of the material such as reworking, action of predators or fluvial transport.
