Under What Conditions Could Eelgrass Measurably Drawdown Carbon? Relating Carbon Drawdown To Pco2, Irradiance, And Leaf Area Index Of Zostera Marina, Tyler Tran
WWU Graduate School Collection
Seagrass meadows, common to coastal habitats, have been identified as potential short-term refugia for calcifying organisms from ocean acidification (OA). In nearshore, soft-sediment habitats of the Salish Sea, eelgrass (Zostera marina L.) is the dominant seagrass species, and several studies have found that eelgrass is effective at taking up inorganic carbon and may be carbon-limited, potentially increasing uptake potential in the future. However, irradiance levels vary throughout a day and can therefore influence rates of carbon uptake and release through the relative rates of photosynthesis and respiration. Eelgrass meadows vary in terms of meadow size, shoot density and morphology, …
Development Of A Rangeland Degradation Risk Model For The Peruvian Andes, Colin Schmidt
Development Of A Rangeland Degradation Risk Model For The Peruvian Andes, Colin Schmidt
WWU Graduate School Collection
This study developed a Rangeland Degradation Risk Model for the Peruvian Andes based on the Unit Stream Powered Erosion Deposition Model using globally available datasets. A supervised land cover classification was conducted to identify suitable grazing areas and to conduct a regional analysis of susceptibility to erosion. Field data were collected from two different study sites, Huascaran National Park and Nor Yauyos Cochas Landscape Reserve, and were used to assess the model’s accuracy in different ecosystems and land use types. Field data were also leveraged to identify additional data needs and other potential drivers of degradation not taken into account …
Isopeptide Ligations Catalyzed By Streptococcus Suis Sortase A, Sarah Bowersox
Isopeptide Ligations Catalyzed By Streptococcus Suis Sortase A, Sarah Bowersox
WWU Graduate School Collection
Chemically modified proteins are critical components of modern therapeutics and basic research. To generate non-natural protein derivatives, bacterial sortase enzymes have been effective due to their ability to catalyze selective ligations between protein targets and functional groups that are uncommon in nature. Thus far, the enzymatic approach using sortase has been limited to modifications at the termini of peptide chains. Here we describe efforts to develop a sortase-mediated strategy for the formation of isopeptide bonds at the side chains of internal lysine residues. To this end, we have identified a sortase A homolog from Streptococcus suis (SrtAsuis) that …
