state of marine mammal population is a
concept with a very large content that is often used fairly intuitively
reference to any clear definition. Several sets of
criteria could be
conservation specifically deals with comparisons of
and distribution data with a supposedly undisturbed initial situation
population would be in equilibrium with their habitats and resources.
status describes fecundity and
mortality parameters which may lead to changes in abundance and
distribution. The health
status of a population describes
the main pathologies and causes of death, including nutritional state
contamination by pollutants, all being processes that determine
and survival of individuals.
the ultimate criteria allowing
one to state that a population has changed. However, the demographic and health
statuses of a population
are also of great interest for management purpose as they permit
processes to be identified before they have fully produced their
population abundance and distribution, thus allowing adapted
decisions to be taken earlier.
