项目摘要

The Web application/database MorphoBank is a modern tool giving scientists a digital workspace to collaborate on matrices in teams worldwide - and in real time. In MorphoBank scientists can add annotated digital images to matrices to support observations of phenotypes. All data are permanently archived in a highly reusable format at no cost to the investigator. Powerful new algorithms have emerged in the last decade that allow investigators to use continuous or morphometric data directly in phylogenetic tree-building. This project will develop new web-based tools to allow investigators to collect and display continuous data in phylogenetic matrices in Morphobank. In this context users can integrate both continuous and discrete variables, can illustrate and label this information and can share the data with the scientific community and the public following publication.Continuous and morphometric data (e.g., relative length of jaw to skull, absolute body size) are commonly collected scientific practice and recognized to be phylogenetically informative. However, integrating continuous with discrete data in online matrices with images is not yet possible. By introducing new tools to organize and graph continuous data through the stable online platform, MorphoBank, paleontologists can better examine how coding practices affect tree-building and can present more robust descriptions of how continuous data from fossils inform the Tree of Life.

Web应用程序/数据库MorphoBank是一个现代工具，为科学家提供了一个数字工作空间，以便在全球团队中进行实时的矩阵协作。在MorphoBank中，科学家可以向矩阵添加带注释的数字图像，以支持对表型的观察。所有数据都以高度可重复使用的格式永久存档，调查员不需要任何费用。在过去十年中出现了强大的新算法，使研究人员能够直接使用连续或形态测量数据来构建系统发育树。该项目将开发新的基于网络的工具，使研究人员能够在Morphobank中收集和显示系统发育矩阵的连续数据。在这种情况下，用户可以整合连续变量和离散变量，可以说明和标记这些信息，并可以在发布后与科学界和公众共享数据。连续的和形态测量的数据（例如，颌骨与颅骨的相对长度，绝对体型）通常被收集到科学实践中，并被认为是系统发育方面的信息。然而，将连续数据和离散数据在带有图像的在线矩阵中进行积分是不可能的。通过引入新的工具，通过稳定的在线平台MorphoBank来组织和绘制连续数据，古生物学家可以更好地研究编码实践如何影响树的构建，并可以更可靠地描述来自化石的连续数据如何为生命之树提供信息。
