The stepwise colonization of islands within an archipelago is typically punctuated by successive founder effects, with each newly founded population being a subsample of the gene pool of the source island. Thus, the genetic signature of successive bottlenecks should be detected when analysing the genetic structure between islands of an...

Determining the causes of a failed eradication of a pest species is important because it enables an argued adjustment of the methodologies used and the improvement of the protocols for future attempts. We examined how molecular monitoring can help distinguish between the two main reasons for an eradication failure (i.e., survival of some...

Determining the inter-island migration abilities of pest species and delimiting eradication units enable more viable long-term eradication campaigns because recurrent colonization from neigbboring islands is avoided. We examined the genetic structure of the invasive Norway rat (Rattus norvegicus) to identify gene flow between islands and...

The giant bathymodioline mussels from vents have been studied as models to understand the adaptation of organisms to deep-sea chemosynthetic environments. These mussels are closely related to minute mussels associated to organic remains decaying on the deep-sea floor. Whereas biological data accumulate for the giant mussels, the small mussels...

New Caledonia archipelago is located in the South West Pacific between Australia and the Vanuatu archipelago. The land covers 19,100 km2, and the EEZ and territorial waters extend to 1,450,000 km2. The main island, Grande Terre, is surrounded by a barrier reef of 1100 km length enclosing a large lagoon of 24,000 km2 and up to 60 m deep. The...
