Adapting Biotoxin Monitoring For The Future: An Opportunity For A Harmful Algae Bloom (Hab) Network In Casco Bay, Maine, Zachary B. Gordon
Adapting Biotoxin Monitoring For The Future: An Opportunity For A Harmful Algae Bloom (Hab) Network In Casco Bay, Maine, Zachary B. Gordon
All Theses And Dissertations
Harmful Algae Blooms (HABs) related to marine biotoxins have considerable impacts on coastal communities and have been increasing in size and frequency globally. Maine is recognized as a leader in biotoxin management as it relates to bivalve shellfish, but it has been unclear how current management practices effect the growth of shellfish aquaculture and how they will adapt to future conditions. This research uses a collaborative approach to analyze the current state of biotoxin management in Maine. First, the current management practices in Maine were compared and contrasted with five other states dealing with similar issues. Then, the perspectives of …
Ichthyoplankton Distribution And Assemblage Within And Around The Saco River Plume, Tracey Bauer
Ichthyoplankton Distribution And Assemblage Within And Around The Saco River Plume, Tracey Bauer
All Theses And Dissertations
A majority of research has focused on the importance of large river plumes for ichthyoplankton survival and recruitment. However, the impacts of smaller, more ephemeral river plumes, such as those commonly found in the Gulf of Maine, on ichthyoplankton are far less understood. The purpose of the current study was to use a small river plume located in the southern Gulf of Maine as a model system to increase our understanding of their effects on ichthyoplankton distribution and diversity, and determine what biotic and abiotic factors may be influencing any differences observed. Plankton tow sampling revealed that although ichthyoplankton abundance …
Application Of A Bioenergetics Framework For Assessing Sub-Lethal Effects Of Pollutants In The Freshwater Mussel Elliptio Complanata, Christopher G. Goodchild
Application Of A Bioenergetics Framework For Assessing Sub-Lethal Effects Of Pollutants In The Freshwater Mussel Elliptio Complanata, Christopher G. Goodchild
All Theses And Dissertations
Although biomarkers are frequently used to assess sublethal effects of contaminants, a lack of mechanistic linkages to higher-level effects limits the predictive power of biomarkers. Bioenergetics has been proposed as a framework for linking cellular effects to whole-animal effects. We investigated sublethal effects of exposure to wastewater treatment facility effluent in freshwater mussels in situ, thereby capturing ecologically relevant exposure conditions. Our study focused on the energetic biomarker AMP-activated protein kinase (AMPK), while also considering more traditional biomarkers like heat shock proteins (HSP70), and antioxidant enzymes (i.e., superoxide dismutase (SOD), glutathione-S-transferase (GST)). We examined biomarkers at mRNA and protein levels. …
