Habitat heterogeneity affects population growth in goshawk Accipiter
... regulation in a territorial breeding system is interference competition. However, this would be expected to cause a more even decrease in individual success with increasing density than site-dependent regulation. 2. We tested these ideas using long-term (1975–99) population data from a goshawk Accip ...
