This project will study the impacts of habitat structure on biodiversity; that is, the variety of forms of life. Habitat structure is the spatial arrangement of plants and resources in natural communities. This structure is important for biodiversity because it affects where organisms can live. The goal of this project is to effectively plan for the future of ecosystems in the face of human impacts. To date, studies have focused on one small aspect of habitat structure—tree canopy height—and have only done studies at small spatial scales. But, habitat structure is more complex than tree canopy height and might change at larger spatial scales when considering local communities up to entire continents. To address this knowledge gap, this project will use bird sightings and data collected from airplanes and satellites to test how habitat structure affects biodiversity at local to continental scales. Findings from this research will help understand the impacts of human disturbance and natural disturbance on habitats and biodiversity. The project will provide results and data for the scientific and educational communities. The project will also train a diverse workforce in ecological research by training middle- and high-schoolers and postdoctoral researchers from groups typically underrepresented in science.This project will provide new insights into the mechanistic underpinnings of avian diversity-vegetation associations through the exploration of the relationships between taxonomic and functional facets of avian diversity and three-dimensional (3-D) vegetation structure across spatial scales from local to continental. This project will expand on existing studies by recognizing the multi-dimensionality of vegetation structure, including both its vertical and horizontal heterogeneity of vegetation. To do so, the project will use air-borne and space-borne Light Detection and Ranging (LiDAR) sensors. Second, this research will identify traits that mediate the associations of avian diversity with 3-D vegetation structure through the exploration of trait-environment relationships. As such, the project will provide a basis for identifying traits that consistently respond to changes in vegetation structure and might hold the strongest potential for predicting future states of avian diversity in the face of habitat modification and loss. Finally, by exploring multiple spatial scales, the project will advance the theoretical foundation of scale dependence in biodiversity-vegetation relationships. Ultimately, the findings will have implications for understanding the impacts of environmental change on biodiversity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将研究栖息地结构对生物多样性的影响；即，栖息地结构是自然群落中植物和资源的空间排列，这种结构对生物多样性很重要，因为它影响生物体的生存环境。该项目的目标是在面临人类影响的情况下有效规划生态系统的未来。迄今为止，研究主要集中在栖息地结构的一个小方面——树冠高度——并且只在小空间尺度上进行了研究。 ，栖息地结构比树冠更复杂为了解决这一知识差距，该项目将使用从飞机和卫星收集的鸟类观测和数据来测试栖息地结构如何影响当地到大陆尺度的生物多样性。该研究的成果将有助于了解人类干扰和自然干扰对栖息地和生物多样性的影响。该项目还将通过培训中高级人员，为科学和教育界提供结果和数据。 -来自的学生和博士后研究人员该项目将通过探索鸟类多样性的分类和功能方面与跨空间尺度的三维（3-D）植被结构之间的关系，为鸟类多样性与植被关联的机制基础提供新的见解该项目将通过认识植被结构的多维性（包括植被的垂直和水平异质性）来扩展现有研究。其次，该研究将通过探索性状与环境的关系来识别介导鸟类多样性与 3D 植被结构之间关联的性状，因此，该项目将为识别性状提供基础。最后，通过探索多个空间尺度，该项目将推进生物多样性尺度依赖性的理论基础。 -植被关系。最终，这些发现将对理解环境变化对生物多样性的影响产生影响。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
