Terrestrial vertebrates (Tetrapoda) include our own species and represent one of the great and diverse evolutionary radiations that intersect with humans' everyday lives. The four tetrapod classes - birds, mammals, amphibians and reptiles - together comprise ca. 33,000 species, include life histories ranging from aquatic, subterranean, and arboreal to aerial, cover a variety of trophic strategies, and harbor some of the most stunning ecological adaptations. Tetrapods play a significant role in providing diverse ecological functions, and they are vital to biodiversity monitoring efforts. However, significant knowledge gaps remain in the evolutionary relationships, distributions of ecologically important traits, and distributions of species. The project will undertake concerted assembling efforts that will yield near species-level completeness of key evolutionary and ecological attributes thereby establishing a global model system for macroevolution, macroecology, comparative biology and global change research. The compiled trait and spatial data will provide a vital backbone for rigorous conservation monitoring and prioritization. The online analysis and visualization tools will extend successful, existing projects and will be built to be directly usable for other taxa and other Genealogy of Life (GoLife) projects. Massive parallel sequencing methods will be used to collect new multi-locus genetic information for ca. 4,000 species currently lacking such data. These data will be used to derive a dated posterior tree set that includes all tetrapod species and captures remaining uncertainty. The posterior tree set will be used to calculate evolutionary distinctness and a variety of tree metrics. Together with key collaborators the researchers will compile morphological, ecological and life history trait data for dozens of variables and additionally benefit from phylogenetic imputation to predict missing values. A new tool incorporated into the existing Map of Life infrastructure will link existing species distributional datasets to global environmental data layers and provide broad-scale niche characteristics for all vertebrates together with estimates of uncertainty. Further integration will link these products to online phylogeny visualization tools to allow map- and tree-based discovery and download. Finally, the project will demonstrate the utility of the integrated layers through example biogeographic, conservation and comparative analyses that will highlight the advance in inference and in predictive conservation use arising from near-complete and unbiased global data. The research will also provide online visualizations and tutorials, a museum exhibit developed around the products, a workshop based on VertLife infrastructure, and undergraduate and graduate summer internships.

陆生脊椎动物（四足型）包括我们自己的物种，代表了与人类日常生活相交的伟大而多样化的进化辐射之一。四个四脚架类别 - 鸟类，哺乳动物，两栖动物和爬行动物 - 共同包括大约。 33,000种，包括从水生，地下和树木到空中的生活历史，涵盖了各种营养策略，以及一些最令人惊叹的生态适应。四足动物在提供多种生态功能方面起着重要作用，它们对于生物多样性监测工作至关重要。然而，在进化关系，生态上重要特征的分布以及物种分布中仍然存在明显的知识差距。该项目将进行一致的组装努力，该努力将产生关键进化和生态属性的物种水平的完整性，从而建立宏观进化，宏观生态学，比较生物学和全球变化研究的全球模型系统。编译的性状和空间数据将为严格的保护监测和优先次序提供重要的主链。在线分析和可视化工具将扩展成功的现有项目，并将构建以直接用于其他分类单元和其他生命谱系（Golife）项目。大量平行测序方法将用于收集CA的新的多洛克斯遗传信息。目前有4,000种此类数据。这些数据将用于得出一个后代的后树集，其中包括所有四足动物物种，并捕获仍然存在不确定性。后树集将用于计算进化的独特性和各种树指标。研究人员将与主要的合作者一起编译数十个变量的形态，生态和生活历史特征数据，并从系统发育插补中受益以预测缺失值。现有的生命基础设施图中的一个新工具将将现有物种分布数据集与全球环境数据层联系起来，并为所有脊椎动物提供广泛的细分特征以及不确定性的估计。进一步集成将将这些产品与在线系统发育可视化工具联系起来，以允许基于地图和树木的发现和下载。最后，该项目将通过示例生物地理，保护和比较分析来证明集成层的实用性，这些分析将突出推理的进步以及靠近完整和无偏见的全球数据引起的预测性保护使用的进步。这项研究还将提供在线可视化和教程，围绕产品开发的博物馆展览，基于Vertlife基础设施的研讨会以及本科和研究生暑期实习。
