Adult survival and per-capita production of young explain dynamics of a long-lived goose population
Population growth rates in geese can be sensitive to small changes in survival and/or production of young, explain more variation in population change can be crucial for implementing effective conservation actions. Here, we show that annual adult survival and production of young (assessed in winter)...
