| benefiting from a migratory prey: spatio-temporal patterns in allochthonous subsidization of an arctic predator. | 1. flows of nutrients and energy across ecosystem boundaries have the potential to subsidize consumer populations and modify the dynamics of food webs, but how spatio-temporal variations in autochthonous and allochthonous resources affect consumers' subsidization remains largely unexplored. 2. we studied spatio-temporal patterns in the allochthonous subsidization of a predator living in a relatively simple ecosystem. we worked on bylot island (nunavut, canada), where arctic foxes (vulpes lagopus ... | 2012 | 22268371 |
