Environmental Dna Is An Effective Method To Monitor Species In Various Freshwater Habitats, Kayleigh Mullen
All Master's Theses
This research investigated the use of DNA shed from individuals into the environment (eDNA) to monitor three amphibian species and two trout species associated with habitat intersected by Interstate-90 in Snoqualmie Pass, Washington. This included a large catchment area within creeks and nearby wetlands historically affected by I-90, including sites where significant habitat improvements had been made. Species-specific primers were used to detect three focal amphibians of varying local abundance and two focal trout species. This study showed successful detection of species across both lentic and lotic systems throughout the study area through efficient multiplexing (detection of multiple species in …

Floral Trait Architecture In Crop Sunflower (Helianthus Annuus) Under Drought Conditions, Lauren Segarra
All Master's Theses
Longer and more intense droughts are predicted to become more common in the coming century due to anthropogenic climate change. Drought can reduce crop yield and decrease food security. In order to mitigate the negative effects of drought on crop production, it is important to elucidate the underlying mechanisms that promote drought stress resistance in crop plants. Floral traits impact yield, especially in oilseed crops such as sunflower (Helianthus annuus), but their susceptibility to drought stress is understudied. The goal of this study was to describe the floral trait architecture of H. annuus crop lines under drought versus …
