Individual variation in movement behaviour and its implications for space use***     Animal movement influences many important ecological properties and processes, such as habitat use, genetic exchange between populations, species interactions, spread of diseases and invasive species, transfer of energy and nutrients, and risk of extinction. Many studies have shown that movement behaviour can be viewed as a personality trait which shows consistent differences between individuals that are maintained under different conditions, such as along an environmental gradient, between levels of predation risk, or over time. Movement behaviour may also be related to other personality traits, forming "movement syndromes" that can be defined as consistent associations of individual movement behaviour with morphological, life-history, or other behavioural characteristics.***     The main goal of my Discovery research program is to understand the biological mechanisms underlying variation in individual movement behaviour, using movement syndromes as a unifying conceptual framework to link movement and other phenotypic traits across different situations. This goal is supported by three objectives related to the following questions: 1) which individual characteristics are correlated with movement behaviour, and how strongly?; 2) do the relationships of movement with other individual characteristics influence ecological performance (growth and survival)?; 3) are these relationships useful to predict movement in novel situations?***     *Our work will focus on brook charr, Salvelinus fontinalis, a fish species of great economic value whose movement in streams can be studied using modern tagging technology that allows us to track individuals and locate them repeatedly over extended time periods. We will use state-of-the-art field and statistical methodologies in experimental settings to systematically quantify the strength, stability, and predictive power of movement syndromes across a range of ecologically relevant situations and to examine the relationship of the syndromes with performance in the wild.***     The ability to link personality traits to processes operating over larger spatial and temporal scales provides a powerful tool for understanding ecological and evolutionary dynamics. An improved understanding of movement syndromes will encourage the application of this approach in other contexts, including its use by managers to evaluate the effects of personality-dependent movements on population persistence, access to critical habitats, impact of invasive species, and disease propagation. This research program will provide training in advanced statistical modelling and modern tagging and tracking technologies to one Ph.D. and three M.Sc. students, as well as exposure to field research in behavioural ecology for at least five undergraduates.**

运动行为的个体差异及其对空间利用的影响 * 动物运动影响许多重要的生态特性和过程，如栖息地利用、种群间的遗传交换、物种间的相互作用、疾病和入侵物种的传播、能量和营养物质的转移以及灭绝的风险。许多研究表明，运动行为可以被视为一种人格特征，它显示了在不同条件下保持的个体之间的一致差异，例如沿着环境梯度，捕食风险水平之间，或随着时间的推移。运动行为也可能与其他人格特征有关，形成“运动综合征”，可以定义为个体运动行为与形态，生活史或其他行为特征的一致关联。 我的发现研究计划的主要目标是了解个体运动行为变化的生物学机制，使用运动综合征作为统一的概念框架，将运动和其他表型特征联系起来。这一目标得到了与以下问题相关的三个目标的支持：1）哪些个体特征与运动行为相关，有多强？2)运动与其他个体特征的关系是否影响生态表现（生长和生存）？3)这些关系对预测新情况下的运动有用吗？* * 我们的工作将集中在溪红点鲑，Salvelinus fontinalis，一种具有巨大经济价值的鱼类，其在溪流中的运动可以使用现代标记技术进行研究，使我们能够在很长一段时间内跟踪个体并重复定位它们。我们将在实验环境中使用最先进的领域和统计方法，系统地量化运动综合征在一系列生态相关情况下的强度，稳定性和预测能力，并检查综合征与野外表现的关系。 将人格特质与在更大的空间和时间尺度上运行的过程联系起来的能力为理解生态和进化动力学提供了一个强大的工具。更好地了解运动综合征将鼓励这种方法在其他情况下的应用，包括管理人员使用它来评估人口持久性，获得关键的栖息地，入侵物种的影响，和疾病传播的个性依赖的运动的影响。该研究计划将为一名博士提供先进的统计建模和现代标记和跟踪技术的培训。和三名硕士生，以及至少五名本科生接触行为生态学的实地研究。
