Eelgrass-macroalgae interactions; context-dependency in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot
Abstract:: This dissertation investigates the context-dependency of species interactions between seagrass and macroalgae in upwelling-influenced estuaries. In all coastal systems, nutrient loading is multidirectional, resulting from mostly freshwater and marine inputs. The directionality of nutrient inputs may affect the rate of supply of organic matter to the system. In systems where...

Surfgrasses (Phyllospadix spp.) as dynamic foundation species for macroinvertebrates along the Oregon coast

Creator:: Moulton, Orissa M.
Abstract:: Foundation species are important components of ecosystems because they provide habitat and ameliorate stressful conditions for residents. This thesis considers the role of surfgrasses (Phyllospadix spp.) as dynamic foundation species on the coast of Oregon in two studies. Chapter 2, which presents an observational survey of two Phyllospadix congeners, investigates...

Patterns of macrophyte wrack deposition on sandy beaches of the Pacific Northwest coast, U.S.A.

Creator:: Reimer, Jessica N.
Abstract:: Dislodged macroalgae and seagrasses, also known as marine wrack, frequently wash into coastal ecosystems from the ocean and are potentially important ecological resources for biological communities. These!nutrient and organic matter subsidies may be especially important on sandy beaches, where little in situ primary productivity exists for higher trophic levels. To...

Impacts of oysters on eelgrass (Zostera marina L.) : importance of early life history stages in response to aquaculture disturbance

Creator:: Wisehart, Lorena Michelle
Abstract:: The importance of seagrasses (families Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae) to estuarine communities is widely accepted and this, combined with their continued decline throughout the world, have resulted in a need to better understand the factors affecting their growth and reproduction. Conservation and restoration of seagrasses will require an understanding...

Marine conservation in Latin America and the Caribbean : an analysis of marine protected areas (MPAs)

Creator:: Guarderas, A. Paulina
Abstract:: Coastal and marine ecosystems in Latin America and the Caribbean are undergoing a rapid and drastic transformation. Dense human populations are concentrated in coastal areas, leading to increased coastal development, destruction of near-shore habitats, pollution, and overexploitation of marine resources. For most Latin American and Caribbean countries, the deterioration of...

The Roles of Recruitment, Species Interactions, and Oceanographic Context in Structuring Rocky Intertidal Communities of the Pacific Northwest and Atlantic Canada

Creator:: Meunier, Zechariah D.
Abstract:: Long-term, large-scale studies of meta-ecosystems provide critical information about how global change influences communities. In my dissertation, I analyzed data from studies encompassing 18 years (2006 – 2023) and over 1,000 km of coastline to investigate drivers of rocky intertidal community structure and dynamics. Specifically, I explored the roles of...

Carbon storage in U.S. Pacific Northwest coastal dunes : the role of invasive beachgrasses and sand supply

Creator:: Stepanek, John
Abstract:: As global atmospheric carbon emissions continue to rise, scientists and land managers are increasingly looking to natural ecosystems to sequester and store carbon to buffer the impacts of climate change. Despite their small geographic size, many coastal ecosystems such as salt marshes, seagrass meadows, and mangroves sequester large amounts of...

Investigating the Role of Dune Grasses, Carbon Storage, and Marine Nutrient Subsidies to the Functions and Services of U.S. Central Atlantic Coastal Dune Ecosystems

Creator:: Jay, Katya R.
Abstract:: Sandy beaches and dunes cover approximately one-third of the world’s ice-free coastlines and provide ecosystem services including coastal protection, recreation, wildlife habitat, and carbon sequestration. These dynamic interface habitats are variably shaped by wind, waves, sedimentary processes, and vegetation feedbacks. Positive biophysical feedbacks lead to the formation of vegetated coastal...

Predictability and constraints on the structure of ecological communities in the context of climate change

Creator:: Barner, Allison K.
Abstract:: Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...

The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...
