Intraspecific and interspecific brood parasitism occur frequently in
waterfowl. We examine the consequences of these behaviors to the
population dynamics of Barrow's and Common Goldeneyes during a 10 year
study period in central British Columbia. The frequency of parasitism was
significantly related to population density and to the availability of
nest sites. High levels of parasitism, in turn, resulted in reduced
reproductive success of females. Using a simulation model based on field
data, we demonstrate that high frequencies of intraspecific parasitism can
lead to the extirpation of local populations. Brood parasitism between
species leads to the additional complication that parasite offspring may
become sexually imprinted on the host species, thereby facilitating
cross-mating and interspecific hybridization. We test this hypothesis
using (1) a comparative analysis of the Anseriformes and (2) field studies
and molecular genetic analyses of interspecific hybridization in
goldeneyes. Our results demonstrate that social interactions such as brood
parasitism may play an important role in determining the long-term
viability of local populations. |
