Behavioural Landscape Ecology of Birds: Scaling-up from Individuals to Populations / Écologie comportementale et du paysage des oiseaux: de l'individu à la population

我的长期研究目标是量化景观结构对物种和个体的运动和分布格局的影响。根据理论，景观的组成和配置决定了资源（如食物和配偶）的空间分布和捕食风险，进而影响动物通过运动对栖息地的采样、选择和利用。到目前为止，关于景观结构如何影响物种或个体分布的实证研究取得了进展，景观结构是根据生境斑块的大小、形状和隔离度来定义的。然而，对于特定资源的分布和相互作用的物种或个体的分布如何调节景观结构（如上所述）的影响，人们的关注却很少。这种知识的缺乏可能是目前景观指标在预测景观尺度上的关键生态过程（如扩散和栖息地选择）方面表现不佳的原因。在接下来的5年里，我和我的学生将专注于景观结构的作用，包括资源的空间显性分布，野生鸟类个体的运动、栖息地利用、资源防御和交配。

My long-term research objective is to quantify the influence of landscape structure on the movement and distribution patterns of species and individuals. According to theory, both the composition and the configuration of landscapes determine the spatial distribution of resources (e.g., food and mates) and predation risk, which in turn affect the sampling, selection, and use of habitats by animals through movement. So far, empirical progress has been made with respect to how landscape structure, defined in terms of the size, shape and isolation of habitat patches, affects the distribution of species or individuals. Yet, poor attention has been given as to how the influence of landscape structure (as defined above) is mediated by the distribution of specific resources and the distribution of interacting species or individuals. This lack of knowledge is likely responsible for the current poor performance of landscape metrics at predicting key ecological processes acting at the landscape scale, such as dispersal and habitat selection. Over the next 5 years, my students and I will focus on the role of landscape structure, including the spatially-explicit distribution of resources, on the movement, habitat use, resource defence and mating of individual wild birds.
