All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

Creator:: Hamner, Rebecca Marie
Abstract:: The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...

Applications of slow-moving autonomous platforms for passive acoustic monitoring and density estimation of marine mammals

Creator:: Fregosi, Selene
Abstract:: Advances in mobile autonomous vehicles for oceanographic sensing provide new opportunities for passive acoustic monitoring of marine mammals. Acoustically equipped mobile autonomous platforms, including gliders, deep-water profiling floats, and drifting surface buoys can survey for a variety of marine mammal species over intermediate spatiotemporal scales. Additionally, such mobile platforms may...

Beached Bones: Exploring the Genetic Impact of Exploitation on the Diversity of Great Whales in the South Atlantic

Creator:: Sremba, Angela L.
Abstract:: Commercial whaling during the 20th century drastically reduced many populations of great whales in the Southern Hemisphere. The Antarctic blue whale, for example, is estimated to have been reduced to less than 0.1% of its original abundance based on catch records and population dynamic models. Despite this population bottleneck, several...

Bioenergetics-based predator-prey relationships between piscivorous birds and juvenile salmonids in the Columbia River estuary

Creator:: Lyons, Donald E.
Abstract:: This dissertation focuses on the predator-prey relationship between two species of avian predators, Caspian terns (Hydroprogne caspia) and double-crested cormorants (Phalacrocorax auritus), and one of their important prey types, juvenile salmonids (Oncorhynchus spp.), in the Columbia River estuary of Oregon and Washington states during the period 1998 – 2007. I...

Body Condition and Hormone Assessment of Eastern North Pacific Gray Whales (Eschrichtius robustus) and Associations with Ambient Noise

Creator:: Lemos, Leila S.
Abstract:: Anthropogenic activities have posed many threats to the oceans and marine life. Understanding how individuals are affected and physiologically respond to these threats is crucial and allows for management and conservation applications. I evaluated the overall health condition of a subpopulation of gray whales (Eschrichtius robustus) along the Oregon coast,...

California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Development and Evaluation of an Animal-borne Active Acoustic Tag to Conduct Minimally Invasive Behavioral Response Studies on Marine Mammals

Creator:: Fregosi, Selene
Abstract:: Development of new research tools is needed to better understand the potential effects of a noisier ocean on individual and populations of marine mammals. Current behavioral response studies utilize ship-mounted sound sources to induce short-term noise-related behavioral responses in tagged animals. Combining the tag with the sound source into an...
