WIWO (NL) - Monitoring and breeding ecology of arctic birds at Medusa Bay

Bird numbers (number of nests or number of territories) of all species within fixed plots were monitored in a standardized way, in order to reveal temporal changes in breeding bird numbers at Medusa Bay. Additionally some important demographic variables were monitored to further explain these changes (i.e. arthropod abundance). Research activities also included research on breeding ecology of Brent Geese in relation to Snowy Owls.
