Impact Of Riverbank Lupine (Lupinus Rivularis) On Grand Fir (Abies Grandis) Ectomycorrhizal Symbioses, Andrew Labay Jan 2023

Impact Of Riverbank Lupine (Lupinus Rivularis) On Grand Fir (Abies Grandis) Ectomycorrhizal Symbioses, Andrew Labay

WWU Graduate School Collection

Lupine (Lupinus rivularis) is used in the revegetation of coarse sediments surrounding the Elwha basin in Washington State due to its ability to improve soil conditions. Previous research illustrated that seeding lupine with conifers increased growth and foliar nitrogen, however, decreased ectomycorrhizal (ECM) root colonization, an important symbiosis for conifers used in restoration. We hypothesized the observed decrease in ECM may be due to lupine increasing soil nitrogen, negating the need for a fungal symbiont. To investigate this, we explored the interaction between lupine and ECM colonization of grand fir (Abies grandis) in both a field …

Activity And Selectivity Of Class B Sortase Enzymes, Sophie Jackson Jan 2023

Activity And Selectivity Of Class B Sortase Enzymes, Sophie Jackson

WWU Graduate School Collection

Gram-positive bacteria attach many proteins to their cell walls via sortase enzymes. Sortases are cysteine transpeptidases and are grouped into 6 classes, A-F. Sortase enzymes, particularly sortase A from Staphylococcus aureus, have been used extensively for in vitro protein ligations. Here, we investigate substrate-binding in sortase A from Streptococcus pyogenes. In addition, class B sortases are typically overlooked for research and development due to low in vitro activity and incomplete knowledge of substrate specificity. Here, we investigate the activity of class B sortases from Bacillus anthracis (baSrtB), Clostridioides difficile (cdSrtB), Listeria monocytogenes (lmSrtB), and Staphylococcus aureus (saSrtB). Of these, …

Magnetic Methods To Characterize The Emplacement Of The Nodule Point Intrusion (Marrowstone Island, Wa), Charlie Nuncio Oct 2022

Magnetic Methods To Characterize The Emplacement Of The Nodule Point Intrusion (Marrowstone Island, Wa), Charlie Nuncio

Geology Graduate and Undergraduate Student Scholarship

The mafic intrusion of Nodule Point, Marrowstone Island, WA has sparse scientific literature to substantiate the local geologic history around its emplacement conditions. To fill this gap, rock magnetism and paleomagnetic methods have been applied to the intrusion and the sandstone of Scow Bay host rock. Samples taken from both lithologies were subject to thermal and alternating field demagnetization to assess paleomagnetic components. The Anisotropy of Magnetic Susceptibility (AMS) of samples was measured, and the maximum axis of susceptibility, K1, was used as an analog to hypothesize emplacement conditions. The host rock: the sandstone of Scow Bay, returned magnetization characteristics …

College of the Environment on the Peninsulas Publications

Heavy metal concentrations often vary at small spatial scales not captured by air monitoring networks, with implications for environmental justice in industrial-adjacent communities. Pollutants measured in moss tissues are commonly used as a screening tool to guide use of more expensive resources, like air monitors. Such studies, however, rarely address environmental justice issues or involve the residents and other decision makers expected to utilize results. Here, we piloted a community science approach, engaging over 55 people from nine institutions, to map heavy metals using moss in two industrial-adjacent neighborhoods. This area, long known for disproportionately poor air quality, health outcomes, …

The Plight Of The Enigmatic Southern Resident Killer Whales: Have We Done All We Can To Recover These Icons Of The Salish Sea?, Orla Robinson, Regan Nelson, Dr. Lance Barrett-Lennard, Carleen Thomas

Salish Sea Ecosystem Conference

Southern Resident killer whales recognize no boundaries but frequent the coastal waters of southern British Columbia (Canada) and northern Washington State (USA). Having acknowledged their conservation plight, the two respective national governments have afforded this distinct and much-valued population the status of ‘Endangered’ under their respective endangered species laws. Divergent natural resource management regimes, endangered species legislation, and marine use profiles in the two nations have at times limited a concerted conservation push for these killer whales. However, much has been learned over the past 20 years about the three primary threats to their recovery - diminished prey (primarily Chinook …
