The diet of harbour seals ( Phoca vitulina ) at the southern limit of its European distribution (Normandy, France)
Changes in habitat availability or resources are likely to have the biggest impact on survival or abundance of individuals found at the extremity of the population’s range. In the case of such marginal populations, the first step in designing appropriate conservation plans is the identification of p...

Changes in habitat availability or resources are likely to have the biggest impact on survival or abundance of individuals found at the extremity of the population’s range.

For example, the interaction between coastal seals and fisheries is often considered as a major conservation issue, due to the potential co-exploitation of the same resources by both fishermen and seals. The diet of harbour seals was investigated by scat analysis at the southern extremity of their European range, in Baie des Veys (Normandy, France).
