Native Perspectives about Coupling Indigenous Traditional Knowledge with Western Science in Geoscience Education from a Focus Group Study

Traditional Knowledge (TK) from Native American/Alaska Native (NA/AN) communities is often met with dismissive attitudes due to its perceived qualitative nature, however, careful examination of what TK represents, and how it formed, leads to the realization that TK is a mixture of qualitative, quantitive, and spiritual knowledge utilizing the same rigor as western science. TK represents knowledge about place, historical insight, and spiritual beliefs with a longstanding and tested understanding about terrestrial and aquatic systems. Theoretical positioning of this study supports the ideology that providing NA/AN students with culturally aligned educational opportunities creates equitable and inclusive learning environments, thereby increasing sense of identity and belonging. We present focus group data collected from two national conferences focused on success of NA/AN students in geoscience. Using a small discussion group format respondents were asked to consider: (1) How do you define science?, (2) How do you define TK?, and (3) What does coupling TK and science mean to you? Our findings revealed a holistic definition of science using typical (e.g., biology, geology, etc.) and atypical (e.g., social science, cultural identity, equity) descriptors. These findings emphasize the importance of developing culturally aligned curriculum across all education levels to support NA/AN students

Silica Biomineralization of Calothrix-Dominated Biofacies from Queen\u27s Laundry Hot-Spring, Yellowstone National Park, USA

Experiments on microorganisms capable of surviving silicification are often conducted to gain a better understanding of the process of silica biomineralization and to gain insights into microbially influenced rock formations and biofabrics like those found in ancient deposits such as the Early Archean Apex Chert formation (Schopf, 1993; House et al., 2000). An ideal microorganism for studying silicification is the large sheathed cyanobacterium Calothrix, which form distinctive organo-sedimentary structures in the low to moderate temperature regions of hydrothermal springs or columnar stromatolitic structures in aquatic systems. Our ability to identify and characterize microfossils from ancient deposits allows us to gain a better understanding of environmental conditions on early Earth. Here we characterized Calothrix-dominated biofacies along the outflow apron of Queen\u27s Laundry Hot-Spring in Yellowstone National Park using microscopy and molecular techniques to examine biofacies morphology and phylogenetic diversity. We found that flow regime and temperature had a profound effect on community composition as identified by the observation of five distinct Calothrix-dominated communities and on biofacies architecture along the outflow apron

Indigenizing Environmental Thinking

we asked people to respond to the following prompt: As we face environmental challenges, such as climate change, extraction economies, (over)development, loss of habitats and ecosystems, pollution, and other harms, what might Indigenous ways of knowing offer to address these global concerns? How might Indigenizing and/or decolonizing our methodologies transform higher education teaching and research
