The Hollister Herbarium at Tennessee Tech University will implement “Rooting Students in their Botanical History” — an educational module targeted for 11th and 12th grade biology students. The module will address “plant blindness,” a phenomenon defined as the failure to notice or appreciate plants. The herbarium will collaborate with three Tennessee high school biology teachers, a videographer, and a graduate research assistant to increase knowledge, awareness, and appreciation of plants over the three-year project. Students also will get to know herbarium specimens as an essential resource for information about the natural world.
This is an NSF Postdoctoral Research Fellowship in Biology, under the program Broadening Participation of Groups Under-represented in Biology. The fellow, Robert Habig, is conducting research and receiving training that is increasing the participation of groups underrepresented in biology. The fellow is being mentored by David Lahti at Queens College, City University of New York. The goal of the fellow's project is to perform a comparative evolutionary analysis of nest construction in the weaverbirds (Ploceus spp.). The evolutionary history of behavior can be nearly intractable and resistant to quantitative analysis. One strategy for illuminating our understanding of behavioral evolution is to conduct comparative studies of animal architectures, such as nests. Unlike behaviors themselves, nests persist through time, and have structures that can be disassociated into several quantitative features, which permits easy and comparable measurements and allows scientists to address questions about evolutionary history and functional relevance. The fellow's research addresses two major questions: (1) How do patterns of nest construction vary within and between species? (2) How do interrelated evolutionary processes shape variation in nest structure? This project is important for advancing foundational scientific knowledge, and will be the first study of weavers incorporating both molecular data and nest morphology to better understand the evolutionary underpinnings of a complex behavioral process. The fellow is also broadening participation in science by mentoring students underrepresented in biology.
The Fellow will reconstruct the evolution of nest construction in Ploceus weaverbirds incorporating advanced phylogenetic and morphological techniques including bioinformatics, computer modeling, X-ray computed tomography, and image processing. The Fellow will also conduct fieldwork in two hotspots of weaverbird diversity, the Awash Valley in Ethiopia and the Limpopo Province of South Africa, and collect behavioral data (e.g. rates of predation and brood parasitism; mating and parental behavior) and morphological data (e.g. nest structure) to test hypotheses of how distinct types of evolutionary selection shape the evolution of nest construction. The proposed comparative study can thus address questions such as how rapidly certain nest structural features evolve, which features are ancestral versus derived, which tend to exhibit phylogenetic signal, and which evolve in response to environmental features. The Fellow is receiving training in three-dimensional morphological analyses, phylogenetic tree construction, bioinformatics, computer modeling, and mentoring skills. The plan to broaden participation includes (1) recruitment, training, and mentoring of Queens College students from underrepresented groups in biology; (2) designing an evolutionary biology curriculum that ties in the research of the fellowship; (3) teaching an evolutionary biology class to underrepresented middle and high school students at the American Museum of Natural History; and (4) facilitating a research team for middle school and high school students.
The RASOR project is designed to increase engagement of students from rural Alaska communities in biomedical/STEM careers. Rural Alaskan communities are home to students of intersecting identities underrepresented in biomedical science, including Alaska Native, low-income, first generation college, and rural. Geographic isolation defines these communities and can limit the exposure of students to scientifically-minded peers, professional role models, and science career pathways. However these students also have a particularly strong environmental connection through subsistence and recreational activities, which makes the one-health approach to bio-medicine an intuitive and effective route for introducing scientific research and STEM content. In RASOR, we will implement place-based mentored research projects with students in rural Alaskan communities at the high school level, when most students are beginning to seriously consider career paths. The biomedical one-health approach will build connections between student experiences of village life in rural Alaska and biomedical research. Engaging undergraduate students in research has proved one of the most successful means of increasing the persistence of minority students in science (Kuh 2008). Furthermore, RASOR will integrate high school students into community-based participatory research (Israel et al. 2005). This approach is designed to demonstrate the practicality of scientific research, that science has the ability to support community and cultural priorities and to provide career pathways for individual community members. The one-health approach will provide continuity with BLaST, an NIH-funded BUILD program that provides undergraduate biomedical students with guidance and support. RASOR will work closely with BLaST, implementing among younger (pre-BLaST) students approaches that have been successful for retaining rural Alaska students along STEM pathways and tracking of post-RASOR students. Alaska Native and rural Alaska students are a unique and diverse population underrepresented in biomedical science and STEM fields.
The lack of diversity in the clinician-scientist workforce is a “very serious concern to the NIH” and to health care professions. Current efforts to broaden participation in STEM fields typically target high school and college-age students. Yet, history and national trends suggest that these efforts alone will not result in rapid or significant change because racial and ethnic disparities are already evident by this time. Children are forming career preferences as early as elementary school, a time when they have little exposure to science and STEM career options. The overall vision of this team is to meet the nation’s workforce goal of developing a diverse, clinician-scientist workforce while meeting the nation’s STEM goals. As a step toward this vision, the goal of This Is How We “Role” is to inspire elementary school students towards careers as clinician-scientists by increasing the number of K-4 students with authentic STEM experiences.
This goal will be attained through two specific aims. The focus of Aim 1 is to distribute and evaluate a K-4 afterschool program across the diverse geographic regions of the US, to support the development of a robust and diverse clinician-scientist workforce. Aim 2 is focused on developing the community resources (afterschool program curriculum, informational books and online certificate program) for promoting health science literacy and encouraging careers in biomedical and clinical research for K-4 students from underserved and underrepresented communities. Combined, these aims will enhance opportunities for young children from underserved communities to have authentic STEM experiences by providing culturally responsive, afterschool educational programs which will be delivered by university student and clinician-scientist role models who are diverse in gender, race, and ethnicity.
Books and an online certificate program about health issues impacting people and their animals (i.e. diabetes, tooth decay) will be developed and distributed to children unable to attend afterschool programs. Further, by engaging veterinary programs and students from across the US, along with practicing veterinarians, this program will examine whether the approaches and curriculum developed are effective across the diverse communities and geographic regions that span the country. Elementary school teachers will serve as consultants to ensure that educational materials are consistent with Next Generation Science Standards, and will assist in training university students and clinician-scientists to better communicate the societal impact of their work to the public.
The program will continue to use the successful model of engaging elementary school students in STEM activities by using examples of health conditions that impact both people and their animals. Ultimately, this project will educate, improve the health of, and attract a diverse pool of elementary school students, particularly those from underserved communities, to careers as clinician-scientists.
