Forage Fish in the California Current Large Marine Ecosystem: Ecological Linkages, Current Catches and Values

Creator:: Cisneros-Montemayor, Andres and Sumaila, Rashid
Abstract:: I begin my talk by identifying the fish species that inhabit the California Current Large Marine ecosystem (CCLME). Next, I categorize these species into predator-prey and forage and non-forage fishes. I then present the current catches, landed values, payment to labour (wages), capital (profit) and payment to the resource owners...

Microeconomic influence of Marine Environment Conditions on Red Seabream Fishery of the Strait of Gibraltar

Creator:: Castilla Espino, David, Bago Sotillo, Elena, and García del Hoyo, Juan José
Abstract:: This paper is aimed at determining the impact of the variability of marine environment conditions on the capture of a vessel that exploit the red seabream fishery of the Strait of Gibraltar. This paper estimates first and second order elasticities of a Translog approximation of a Stochastic Distance Functions of...

The Effect of the Environment on California's Commercial Fisheries

Creator:: Norton, Jerrold and Herrick, Samuel Jr
Abstract:: Long-term, naturally occurring cycles can cause significant shifts in marine ecosystems referred to as regime shifts. While the new regime can be as diverse and ecologically acceptable as that which it replaced, individual species may completely disappear or be greatly depressed when a regime shift occurs. In this work we...

Assessing the Impact of Mpas on Recreational Uses of A Marine Ecosystem: the Case of the Côte Bleue Marine Park (France)

Creator:: Lavisse, Elodie, Charbonnel, Eric, Le Direach, Laurence, Roncin, Nicolas, Wilson, James, Boncoeur, Jean, and Alban, Frédérique
Abstract:: Though the basic purpose of MPAs is marine ecosystem conservation, the question of their influence on the local economy is often critical since it governs their social acceptability. This paper addresses the problem of measuring the consequences of creating a marine protected area (MPA) on recreational extractive and non-extractive uses...

Habitat use, spatial ecology, and stable isotope variability of the Pacific harbor seal (Phoca vitulina richardii) along the Oregon coast

Creator:: Steingass, Sheanna M.
Abstract:: Pacific harbor seals (Phoca vitulina richardii) are one of Oregon’s most common coastal predators, numbering between 10,000 and 12,000 individuals (Brown et al. 2005b). They consume more than 149 species or types of marine prey within the Pacific Northwest, which include a large variety of commercially important fisheries species. Despite...

Disturbances in a marine bacterioplankton system drive community assembly towards niche-based processes

Creator:: Vergin, Kevin L.
Abstract:: Over 100 monthly bacterioplankton DNA samples, from each of the surface and 200 m depths at the Bermuda Atlantic Time-series Study (BATS) site, were analyzed for community assembly processes. Correlation networks, filtered for potential autocorrelation artifacts, were constructed for each depth. Network characteristics for the two depths were remarkably similar...

Ecology and Environmental Controls of Two Keystone Groups of Oceanic Microorganisms : Diazotrophs and Pathogenic Vibrio

Creator:: Gradoville, Mary Rose
Abstract:: Marine bacteria play vital roles in every niche of the ocean, from small-scale symbioses to large-scale productivity and the regulation of Earth’s climate. Recent advances in molecular tools now allow us to probe the genetic potential of entire microbial communities. The next step is linking these diverse communities to the...

The Effects of Phytoplankton Prey Species and Nutrient Limitation on Microzooplankton

Creator:: McBeain, Kelsey Ann
Abstract:: Phytoplankton and microzooplankton comprise the base and the first link of the marine food web, respectively. These microbes are key drivers of marine carbon and nutrient cycles. Phytoplankton convert atmospheric CO₂ into organic carbon, and microzooplankton consume phytoplankton, packaging phytoplankton carbon into particulate forms that have a variety of fates:...

Effects of the invasive Pacific red lionfish Pterois volitans on native Atlantic coral-reef fish communities

Creator:: Albins, Mark A.
Abstract:: Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the...

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...
