POPULATION-DYNAMICS IN MIGRATORY AVIAN COMMUNITIES AT DIFFERENT SPATIAL AND TEMPORAL SCALES

The dynamics of migratory avian communities were compared over different spatial and temporal scales using data from the Mettnau-Reit-Illmitz migratory bird trapping program. Bird species that had similar year-to-year population fluctuations did not have similar long-term population trends. Species that had similar population dynamics at one trapping station only rarely exhibited similar dynamics at any of the other trapping stations.
