Atlantic Puffin (Fratercula arctica) Foraging Ecology During Marine Heatwave Conditions

Creator:: Kennerley, William L.
Abstract:: Marine heatwaves (“MHWs”) are discrete periods of anomalously warm ocean conditions that can lead to shifts in the distribution and abundance of marine organisms. Low-trophic level, pelagic forage species are frequently among those affected by MHWs, often resulting in considerable impacts upon their predators. In the North Atlantic Ocean, Atlantic...

Spatial Association of Humpback Whales (Megaptera novaeangliae) and their Prey in the Southern Gulf of Maine, USA

Creator:: Kirchner, Theresa
Abstract:: Efficient foraging strategies result in a predator spatially overlapping with its prey, foraging in the most profitable patches, and minimizing the time transiting between patches. Previous studies investigating baleen whale foraging strategies have generally focused on investigating spatial overlap with prey patches, patch profitability or movement within feeding grounds. The...

The Soundcheck of the Sea : Comparing Marine Soundscapes on a Continental Scale

Creator:: Haver, Samara M.
Abstract:: Monitoring marine ambient sound using standardized methods supports assessments of ocean sound levels across widespread ecosystems. This thesis quantifies differences among coastal and deep-water marine soundscapes in the Atlantic and Pacific oceans. The sources of sound in a soundscape are compartmentalized into three components and compared over time and among...

Long Term Trends and Sources of Sound in United States Waters

Creator:: Haver, Samara M.
Abstract:: Passive acoustic monitoring is a valuable tool for observing the status of marine environments. Comparisons of underwater soundscapes over temporal and spatial scales can provide data to inform marine conservation efforts, including protection of threatened and endangered species. This dissertation utilizes passive acoustic data collected via a broadly spaced array...

Movement, dive behavior, and habitat-use of common murres (Uria aalge) in the Northern California Current System under variable ocean conditions

Creator:: Loredo, Stephanie A.
Abstract:: Year-round habitat use of marine predators provides knowledge of important marine areas throughout different life stages. Large-scale, environmental variability, both in space and time, causes changes in the behavior and distribution of marine predators that are important to quantify for conservation. In the Northern California Current System (NCCS), common murres...

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...

Tonight’s Specials Include Mysids, Amphipods, and More: An Examination of the Zooplankton Prey of Oregon Gray Whales and its Impact on Foraging Choices and Prey Selection

Creator:: Hildebrand, Lisa
Abstract:: Understanding prey quality and prey selection by predators is critical for management efforts aimed at identification and protection of essential habitats and prey. Marine predators must make daily foraging choices in a heterogenous and dynamic environment in order to meet the high energetic demands of migration, reproduction and foraging. With...

The Effect of Group Size on Individual Roles and the Potential for Cooperation in Group Bubble-net Feeding Humpback Whales (Megaptera novaeangliae)

Creator:: Mastick, Natalie
Abstract:: Group foraging is observed in many species as a means to increase the ability of members of the group to find and exploit patchy prey. Group foraging can be exhibited in a number of different contexts based on the relationships between the participants, including by-product mutualism. One variant of by-product...

Carbon Dynamics Associated with Land Cover Change in Tropical Mangrove Ecosystems of the Mahakam Delta, East Kalimantan, Indonesia

Creator:: Arifanti, Virni B.
Abstract:: The Mahakam Delta which was once among the largest mangrove forests in Indonesia, has been subjected to dramatic changes in structure and function due to massive shifts from mangrove forest to shrimp ponds and oil and gas development. To understand the impacts of mangrove loss to the greenhouse gas (GHG)...

Jumping in with Both Feet: Exploring Factors that Shape Juvenile Amphibian Movement

Creator:: Bredeweg, Evan M.
Abstract:: Investigation into how animals move within the landscape is important for both understanding of ecological processes and conservation management. Animal movement is important in shaping life history transitions, demographics, individual fitness, and species distributions. However, as landscapes become increasingly affected by human activities, movement becomes important as species navigate landscapes...
