To date, studies that have addressed the impacts of global changes have mainly focused on linkingclimate variability and/or human disturbances to individual life history traits, population dynamics ordistribution. However, individual behavior and plasticity mediate these responses. The goal of this projectis to understand mechanisms linking environmental changes (climate & fisheries) - behavioral personalitytype - plasticity in foraging behaviors - life history traits - population dynamics for a seabird breeding inthe southern ocean: the wandering albatross. This project will also forecast the population structure andgrowth rate using the most detailed mechanistic model to date for any wild species incorporatingbehaviors in an eco-evolutionary context. Specifically, the investigators will (1) characterize the lifehistory strategies along the shy-bold continuum of personalities and across environmental conditions; (2)understand the link between phenotypic plasticity in foraging effort and personality; (3) characterize theheritability of personality and foraging behaviors; (4) develop a stochastic eco-evolutionary model tounderstand and forecast the distribution of bold and shy individuals within the population and theresulting effect on population growth rate in a changing environment by integrating processes from goals1, 2 and 3. To date, this has been hampered by the lack of long-term data on personality and life historiesin any long-lived species in the wild. For the first time ever, we have tested in a controlled environmentthe response to a novel situation for ~1800 individuals for more than a decade to define individualpersonality variation along the shy-bold continuum that we can relate to the life history traits over theentire species life cycle using unique long-term individual mark-recapture data sets for this iconic polarspecies. The novelty of this project thus lies in the combination of personality, foraging and demographicdata to understand and forecast population responses to global change using state-of-the-art statisticalanalysis and eco-evolutionary modeling approaches.

迄今为止，已经解决了全球变化影响的研究主要集中在关节可变性和/或人类骚乱与个人生活历史特征，人口动态命令上。但是，个体行为和可塑性介导了这些反应。该项目的目的是了解将环境变化（气候与渔业）联系起来的机制 - 行为人格型 - 觅食行为的可塑性 - 生活历史特征 - 南方海洋中海鸟繁殖的种群动态：徘徊的Albatross。该项目还将使用最详细的机械模型预测人口结构和生长速率，以迄今为止，在生态进化环境中融合了bebehaviors的任何野生物种。具体而言，调查人员（1）将描述性格连续性以及跨环境条件的生命历史策略； （2）了解表型可塑性在觅食努力和人格中之间的联系； （3）表征性格和觅食行为的可遗忘性； （4）开发一种随机的生态进化模型Tounderstand，并预测了人口中大胆和害羞的个体的分布，以及通过整合目标1、2和3的过程中对环境中人口增长率的影响对人口增长率的影响。到目前为止，这受到了由于对人格和生命的长期数据缺乏长期数据而在野生中缺乏长期数据的阻碍。有史以来，我们第一次在受控的环境中测试了对〜1800个人的新局势的反应，十多年来，我们使用独特的长期个人标记性数据集来定义我们可以与Theentire物种生命周期相关的害羞的连续体变化，这些变化与enterire物种生命周期的生命历史特征有关。因此，该项目的新颖性在于人格，觅食和人口统计学的结合，以了解和预测种群对全球变化的响应，使用最新的统计分析和生态进化的建模方法。
