This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Red algae are among the dominant photosynthetic organisms in the sea. Many are leafy seaweeds, but a large number grow as crust-like pavements on the ocean floor. This project will examine molecular gene sequences and morphological structures in a re-evaluation of the classification and evolution of these crust-like red algae. Using new as well as existing collections of algae, a specimen-based systematic treatment will be produced. The study will provide correct names, species and genus descriptions, and decipher phylogenetic relationships of these red algae worldwide. This family is of great ecological significance in the deep-water marine environments worldwide, with some species involved in the establishment of red algal nodules common in the deep sea. This project will provide resources essential to future research and educational training in the biodiversity of seaweeds that share a crust-like habit. The results of this study should prove useful as a basis for interpreting morphological evolution and systematic relationships within a phylogenetic framework in other groups of red algae. Training and outreach will be conducted at many levels, including the production of databases and websites, and the posting of video clips on YouTube in order to reach a wide audience that may not be familiar with the concepts of basic scientific research, biodiversity, marine algae, or evolutionary approaches in general. These video clips will be easily accessible in K-12 classrooms in Louisiana and beyond.

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。红藻是海洋中的主要光合作用生物之一。许多是多叶的海藻，但也有大量生长在海底的贝壳状人行道上。该项目将研究分子基因序列和形态结构，以重新评估这些结壳状红藻的分类和进化。利用新的和现有的藻类收集，将产生基于标本的系统处理。这项研究将提供这些红藻的正确名称、物种和属的描述，并破译世界范围内这些红藻的系统发育关系。该科在全球深水海洋环境中具有重要的生态意义，一些物种参与了深海常见红藻结节的建立。该项目将为今后关于海藻生物多样性的研究和教育培训提供必要的资源，这些海藻有着类似外壳的习性。这项研究的结果应该被证明是有用的，作为解释其他红藻群体的形态进化和系统发育框架内的系统关系的基础。将在多个层面开展培训和外联活动，包括制作数据库和网站，并在YouTube上发布视频短片，以便接触到可能不熟悉基础科学研究、生物多样性、海洋藻或一般进化方法概念的广大受众。这些视频剪辑将很容易在路易斯安那州和其他地方的K-12教室中获得。
