Resilience and vulnerability of the Northern Gannet (Morus bassanus): characterization of the behavioral and physiological responses to the global changes based on the pluriannual reproductive success
1. PLURIANNUAL REPRODUCTIVE SUCCESS, PREDATORS, PREY, AND ENVIRONMENTAL VARIABILITY To describe the response of the population of Northern gannets according to the variability of the availability of its main prey and some environmental factors in the Gulf of Saint Lawrence to highlight the most sensitive reproductive parameters and life history traits. 2. PLURIANNUAL REPRODUCTIVE SUCCESS, FORAGING BEHAVIOR, AND INTER-INDIVIDUAL VARIABILITY To compare the foraging strategies of the individuals with highest pluriannual reproductive successes (PRS) with those who present the lowest PRS. This objective aims at characterizing and at distinguishing on the behavioral plan the resilient individuals and the vulnerable individuals in the global changes. 3. PLURIANNUAL REPRODUCTIVE SUCCESS, HEALTH STATUS, AND INTER-INDIVIDUAL VARIABILITY To compare the individuals with the highest PRS with those who present the lowest PRS according to the sex, the divorce rate, the physical condition, the nutritional status and the oxidative stress. This objective aims at explaining the parental quality of gannets as well as their individual resilience or vulnerability in front of global changes.
