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；也就是说，各种各样的生活形式。栖息地结构是植物和资源自然社区的空间布置。这种结构对生物多样性很重要，因为它会影响生物可以居住的地方。该项目的目的是有效地为面对人类影响的生态系统的未来计划。迄今为止，研究集中在栖息地结构的一个小方面（树冠层高度）上，并且仅在小空间尺度上进行了研究。但是，栖息地结构比树冠的高度更为复杂，在考虑当地社区直至整个延续时，可能会在较大的空间尺度上发生变化。为了解决这个知识差距，该项目将使用从飞机和卫星收集的鸟类目击者和数据来测试栖息地结构如何影响当地至连续尺度的生物多样性。这项研究的发现将有助于了解人类灾难和自然灾害对栖息地和生物多样性的影响。该项目将为科学和教育社区提供结果和数据。该项目还将通过培训中学和高中生和博士后研究人员的培训，这些劳动力在科学方面通常不足以代表性不足。该项目将提供新的见解，以通过探索分类和跨性别的跨性别性（3​​多）的构建范围的相关性来对鸟类多样性蔬菜的机械基础，从连续。该项目将通过认识到植被结构的多维性，包括其植被的垂直和水平异质性，从而扩展现有研究。为此，该项目将使用空中和太空传播的光检测和射程（LIDAR）传感器。其次，这项研究将通过探索特质环境关系来确定介导鸟类多样性与3-D蔬菜结构的关联的特征。因此，该项目将为识别始终如一地响应蔬菜结构变化的特征提供基础，并可能在面对栖息地的修改和损失时具有强大的潜力来预测未来的鸟类多样性状态。最后，通过探索多个空间尺度，该项目将推动生物多样性蔬菜关系中规模依赖性的理论基础。最终，调查结果将对理解环境变革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知识分子优点和更广泛的影响评估标准来评估诚实地通过评估来诚实地支持。
