The Effect Of Blue Mussel (Mytilus Edulis) Extinction On Ecosystem Function In The Gulf Of Maine Rocky Intertidal, Sophia K. Montague
The Effect Of Blue Mussel (Mytilus Edulis) Extinction On Ecosystem Function In The Gulf Of Maine Rocky Intertidal, Sophia K. Montague
Honors Theses
Stressors associated with climate change including thermal stress and ocean acidification inhibit the growth and reproduction of many species, including the ecologically and economically important blue mussel species in the Gulf of Maine (GOM). Established scaling relationships between mussel size, abundance, and water filtration suggests that the decline of mussels will stunt GOM water filtration. This change in the rate of water filtration could have large effects on the abundance of phytoplankton, abundance of invertebrate larvae, abundance of nutrients and organic material, food web stability, and biodiversity. Overall, this thesis explores the effect of blue mussel (Mytilus edulis) …
Development And Validation Of Gene Delivery Methods For Crassostrea Virginica, Adrienne N. Tracy
Development And Validation Of Gene Delivery Methods For Crassostrea Virginica, Adrienne N. Tracy
Honors Theses
The Eastern oyster (Crassostrea virginica) is an important part of the East Coastal USA economy because aquaculture creates jobs. Sadly, the oysters are under constant threat due to increasing pollution, red tides, and diseases. Bivalves, and oysters in particular, are also becoming potential model organisms in medical research. With the sequencing of the oyster genome, scientists are focusing on deciphering the function of the predicted genes. However, the limited number of molecular and cellular tools available makes functional annotation of the genome challenging. A consistent, replicable gene delivery system needs to be developed to assess gene function and understand the …
The Impact Of Climate Change On The Migration Phenology Of New England’S Anadromous River Herring And American Shad, Charles K. Cobb
The Impact Of Climate Change On The Migration Phenology Of New England’S Anadromous River Herring And American Shad, Charles K. Cobb
Honors Theses
Anadromous fish play important roles in food webs and nutrient cycling in both aquatic and marine ecosystems. As a result of climate change however, anadromous fish’s migration timing has begun to change, with potentially deleterious consequences to both anadromous fish, and the species that depend on them. Western coastal US studies have linked earlier anadromous fish returns to warming marine temperatures and changes in river flow regimes, but the exact temperatures thresholds that anadromous fish respond to, and the relative importance of temperatures and river flows, remain somewhat unknown. Additionally, there has been relatively little research on anadromous fish phenology …
Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton
Mathematical Modeling Of Emiliania Huxleyi And A Host-Specific Virus, Julia Middleton
Honors Theses
The world’s oceans provide the basis for life on the planet. One microscopic algae, the coccolithophores, and Emiliania huxleyi in particular, is a major source of carbon drawdown in the context of the global carbon cycle and account for a significant amount of the primary production in oceanic ecosystems. We know that the oceans are packed with marine viruses and they have an important role in the rise and fall of plankton populations but current mathematical models do not accurately account for virus-host interactions when predicting plankton blooms. Therefore I am using model optimization and comparison techniques to evaluate current …
The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin
The Role Of Underutilized Fish In New England's Seafood System, Taylor Witkin
Honors Theses
The global fisheries crisis has led to an increasing recognition for the need to relieve pressure on overfished, popular food fish stocks. Opportunities exist to shift consumer demand toward more sustainable choices, including fish that may be locally abundant. Attempts have been made to market underused fish (sometimes termed “trash fish”) that represent more sustainable alternatives; however, it is unclear whether consumers will choose to purchase these more sustainable options, particularly if underused fish are also unfamiliar. Chapter 1 reviews existing research and current issues surrounding sustainable seafood and the recent shift toward local, abundant, undervalued species in New England’s …
