functional response of staging semipalmated sandpipers feeding on burrowing amphipods. | despite its fundamental relevance to many ecological processes in predator-prey relationships, the functional response, which relates predator intake rate to prey density, remains difficult to document in the field. here, i document the functional response of semipalmated sandpipers (calidris pusilla) foraging on a burrowing amphipod corophium volutator during three field seasons at the peak of fall migration in the upper bay of fundy (new brunswick, canada). i gathered data during the ebbing ti ... | 2009 | 19543917 |
