Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:

Kaltenberg, Amanda May

Abstract:

Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

Foraging ecology, diving behavior, and migration patterns of harbor seals (Phoca vitulina richardii) from a glacial fjord in Alaska in relation to prey availability and oceanographic features

Creator:

Womble, Jamie N.

Abstract:

Understanding the movement behavior and foraging strategies of individuals across multiple spatial and temporal scales is essential not only for understanding the biological requirements of individuals but also for linking individual strategies to population level effects. Glacial fjords scattered throughout south-central and southeastern Alaska host some of the largest seasonal...

Natal source contributions of Pacific cod (Gadus macrocephalus) recruits in the southeastern Bering Sea

Creator:

DiMaria, Ruth A.

Abstract:

Effective and sustainable fisheries management not only depends on identifying and defining stocks (fundamental unit of management), but also on having knowledge of factors influencing the abundance, distribution and connectivity of stocks. Population structure of Pacific cod (Gadus macrocephalus) in the southeastern Bering Sea (EBS) remains unresolved although genetic data...

Identifying habitat factors for canary rockfish (Sebastes pinniger) off Washington and Oregon using environmental data and trawl logbooks

Creator:

Vestfals, Cathleen D.

Abstract:

If fisheries managers are to effectively manage commercially exploited fish populations, a basic understanding of the factors that influence fish distribution and abundance is required. In 2005, efforts to identify Essential Fish Habitat (EFH) for the 82 groundfish species managed by the Pacific Fishery Management Council along the West Coast...

Function of Oregon Estuaries to Juvenile Fishes, with Focus on Juvenile Rockfishes (Sebastes spp.) in Yaquina Bay, Oregon

Creator:

Schwartzkopf, Brittany D.

Abstract:

The role that anthropogenic and natural habitats in estuaries play in long-term population trends for Oregon’s nearshore marine fishes is poorly understood, in part due to limited temporal sampling. One important nearshore marine group is northeastern Pacific rockfishes (Sebastes spp.), which are highly diverse, with around 96 documented species, and...

Maternal effects, the environment, and age structure: A mechanistic fine-scale approach to describe a complex set of factors contributing to larval growth and survival

Creator:

Arnold, Linsey M.

Abstract:

The relationship between population characteristics and population productivity is fundamental to sustainable fisheries management, but predicting productivity remains a challenging task. Proposed mechanisms driving the variability in productivity at a given population size have included environmental and demographic factors related to the age structure of the population, but the broad-scale...

The Factors Affecting the Diets of Groundfish in the Gulf of Alaska : Ecological and Modeling Considerations

Creator:

Thompson, Kevin A.

Abstract:

Marine systems undergo changes in community composition over time as a result of a variety of environmental and anthropogenic factors. Understanding these community changes and the factors that drive them is critical for ecosystem management of marine resources. The Gulf of Alaska (GOA) is a large marine ecosystem that includes...

Influence of Novel Ocean Conditions on Life History Characteristics of a Nearshore Rockfish with Implications for Population Assessment and Management

Creator:

Rosemond, Rebecca C.

Abstract:

The California Current Large Marine Ecosystem (CCLME), located on the eastern boundary of the North Pacific Ocean, is highly dynamic, with variable conditions driven by seasonal upwelling, regional oceanography, and broad scale climate patterns. In the last decade, the northeast Pacific Ocean has experienced several marine heatwaves (MHWs), prolonged periods...

Eyes on the Seafloor : Using Video Tools to Monitor Benthic Communities at Dredged Material Disposal Sites at the Mouth of the Columbia River

Creator:

Fields, Stephanie A.

Abstract:

The mouth of the Columbia River (MCR) is an intersection of more than a river and ocean, but also multiple economically valuable activities including dredging to maintain a deep draft shipping channel and an active Dungeness crab (Metacarcinus magister) fishery. More than three million cubic meters of sediment are annually...

Provisioning, growth and survival of Adélie penguin chicks at Cape Crozier, Ross Island, Antarctica

Creator:

Jennings, Scott

Abstract:

Understanding the factors that contribute to or limit reproductive success is a fundamental objective of the field of ecology, providing insight into the ways ecosystems function and facilitating better management of natural resources. Behaviors that benefit offspring often increase costs to parents, and thus parents must adjust their level of...
