Birds of prey as limiting factors of gamebird populations in Europe: A review

Article Abstract:

The role of predators as limiting factors of prey populations has created conflicts between predators and human hunters since the hunters are likely to see predators as competitors for the same resources. The percentage of a given prey species in the diet of an avian predator does not necessarily reflect the impact of that predator on densities of prey populations.

Article Abstract:

Around 814 functional responses from 235 studies are reviewed showing that type I responses are not only exceptionally frequent among filter feeders but that they have only been reported from these consumers. The findings can be understood by considering the conditions that a consumer must fulfill in order to show a type I response.

Unstable dynamics and population limitation in mountain hares

Article Abstract:

Trophic interactions, either predator-prey or host-parasite, is the major factor limiting populations of mountain hare thus contributing to the unstable dynamics. Severe weather and food limitations could be other contributing factors for an unstable dynamics.
