Ulva Spp. Bloom Dynamics In A Hyper-Eutrophic Estuary: Jamaica Bay, New York, Annesia Lamb

Dissertations, Theses, and Capstone Projects

In this dissertation, I present three studies that further our understanding of macroalgae identity, growth, and proliferation. Eutrophication is prevalent in shallow coastal ecosystems world-wide. One of the ecosystem consequences is the development of a bloom forming green marine macroalgae, Ulva spp. Ulva can have negative effects such as Zostera spp. degradation, fish, and shellfish declines. I performed assessments of (1) identity of the bloom-forming Ulva and other macroalgae assemblage, (2) physical, chemical, and biological drivers of Ulva bloom growth and proliferation, and (3) optimal irradiance and temperature requirements for early growth stages in Ulva linza.

The Distribution, Abundance, And Gut Microbiome Of Ribbed Mussel, Geukensia Demissa, Across Natural And Restored Salt Marshes In Jamaica Bay, New York, Bethany Freynk

Student Theses and Dissertations

Coastal wetlands perform valuable functions by protecting shorelines from floodwaters and storm surges, providing habitats for marine species, and improving local water quality. Unfortunately, over half of the area of global wetlands has been lost over the past century. Locally, in Jamaica Bay (Queens, NY), loss of wetlands has exceeded 98%. Restoration of Jamaica Bay marshes began in 2003. Ribbed mussels, Geukensia demissa, live symbiotically with marsh plants and have been shown to stabilize sediments and provide organic nutrients that enhance marsh plant growth. Mussels are suspension feeders, which collect algae from seawater and deposit organic matter in marsh sediments. …
