The Finnish population of White-tailed Eagle (Haliaeetus albicilla) has gone through two major demographic bottlenecks during the last two centuries. Strong conservation measures have allowed the population to recover, but despite the rapid population growth during recent years the species is still classified as endangered. We studied the genetic population(More)
Top predators may induce extensive cascading effects on lower trophic levels, for example, through intraguild predation (IGP). The impacts of both mammalian and avian top predators on species of the same class have been extensively studied, but the effects of the latter upon mammalian mesopredators are not yet as well known. We examined the impact of the(More)

Previous studies on intraguild predation have mainly focused on within-class assemblages, even though avian top predators may also influence mammalian mesopredator prey. By using nation-wide long-term data from Finland, northern Europe, we examined the impacts of golden eagles (Aquila chrysaetos) together with red foxes (Vulpes vulpes) and pine martens(More)
