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...
