A goal of the Tribal Colleges and Universities Program (TCUP) is to increase the science, technology, engineering and mathematics (STEM) instructional and research capacities of specific institutions of higher education that serve the Nation's indigenous students. Expanding the research efforts of faculty at these institutions expands the opportunities of their students to pursue challenging, rewarding careers in STEM fields, provides for research studies in areas that may be culturally significant, and encourages a community and generational appreciation for science and mathematics education. This project aligns directly with that goal, and moreover will inform the body of knowledge about issues of biological significance. The proposed research focuses on the production of culturally relevant berry and root crops on agricultural land within a coastal marine ecosystem. The goals are to: 1) establish and cultivate traditional berry and roots crops on tribally owned land and link food quality to soil quality; and 2) increase faculty research capacity and engage tribal college students in soil ecology, plant biology, and ethnobiology. The connection of faculty to research and thereby the students to culturally and geographically relevant research is an important step in retaining students who are more likely to pursue advanced degrees. The faculty research project tests hypotheses that state a) increased biological diversity increases the level of phytonutrients in perrenial and annual traditional plants, and b) low input, organic nitrogen applications will increase biological diversity and the percentage of organic matter in soil, and reduce the amount of nitrate activity in plant tissue. A cultivation system of traditional plants will be established with fertility treatments applied and assessed over a two-year period. Plant tissue will be examined for survival and growth, phytonutrients and nitrate activity, and yield. Additionally, soil quality, biologic activity, and biodiversity metagenomic analysis will be performed. The PI will collaborate with partners at the Northwest Indian College Institute for Indigenous Foods and Traditions and the Swinomish Tribal Community, as well as advisors at the University of Victoria, USDA-ARS Horticultural Unit, and the Confederated Tribes of the Umatilla Indian Reservation Department of Science, Engineering, and Energy. This project will provide: 1) a venue for demonstrating and investigating regionally significant best management practices (BMPs) for soil management and restoration; 2) new methods for quantifying the nutritional value and physiological response of traditional plants; and 3) culturally relevant research and education opportunities for faculty and students.

部落学院和大学方案的一个目标是提高为全国土著学生服务的特定高等教育机构的科学、技术、工程和数学教学和研究能力。扩大教师在这些机构的研究工作扩大了他们的学生的机会，追求具有挑战性的，有价值的职业生涯在干领域，提供了在可能具有文化意义的领域的研究，并鼓励社区和一代人欣赏科学和数学教育。该项目直接与这一目标相一致，而且将为有关生物学意义问题的知识体系提供信息。拟议的研究重点是在沿海海洋生态系统内的农业用地上生产与文化相关的浆果和块根作物。目标是：1）在部落拥有的土地上种植传统浆果和根茎作物，并将食品质量与土壤质量联系起来; 2）提高教师研究能力，让部落大学生参与土壤生态学、植物生物学和民族生物学。教师与研究的联系，从而学生与文化和地理相关的研究是留住更有可能攻读高级学位的学生的重要一步。教师的研究项目测试的假设，状态a）增加生物多样性增加植物营养素的水平在多年生和一年生传统植物，和B）低投入，有机氮的应用将增加生物多样性和土壤中有机质的百分比，并减少硝酸盐的活性在植物组织中的量。将建立一个传统植物的栽培系统，在两年的时间内实施和评估肥力处理。将检查植物组织的存活和生长、植物营养素和硝酸盐活性以及产量。此外，还将进行土壤质量、生物活性和生物多样性宏基因组分析。PI将与西北印第安学院土著食品和保护研究所和Swinomish部落社区的合作伙伴，以及维多利亚大学，USDA-ARS园艺部门和Umatilla印第安保留地科学，工程和能源部联合部落的顾问合作。该项目将提供：1）展示和调查区域重要的土壤管理和恢复最佳管理实践（BMPs）的场所; 2）量化传统植物的营养价值和生理反应的新方法; 3）为教师和学生提供文化相关的研究和教育机会。
