Diel activity patterns in demersal fishes on Heceta Bank, Oregon

Creator:: Hart, Ted
Abstract:: Most fishes exhibit differences in activity patterns from day to night, with a switch from high to low activity at dusk and reverse at dawn. Marine reef fishes show similar behavior among sites, despite dissimilar species assemblages, suggesting that common selection pressures are leading to convergent behavior. Few studies to...

Long-term Colonization Of A Subarctic Artificial Reef System In Whittier, Alaska

Creator:: Levy, Charlotte S. and Brown, Eloise J.
Abstract:: Over half of the U.S. coastline is found in Alaska, and the majority of the state’s economic activity occurs along the coast. Increased coastal development poses a potential threat to nearshore habitats in Alaska. The installation of artificial reef (AR) systems can mitigate habitat loss; however, few AR systems have...

Diver observations of community structure on a subarctic marine artificial reef in Whittier, Alaska

Creator:: Levy, Charlotte
Abstract:: Increased coastal development poses a potential threat to nearshore habitats in Alaska, and artificial reefs (AR) are an increasingly popular tool for mitigating habitat loss. Although well studied in tropical and temperate locations, less is known about AR efficacy in high latitude locations. Since ARs are heavily influenced by ecological...

Light and the behavior of pelagic animals during night and crepuscular periods

Creator:: Wisdom, Daniel W.
Abstract:: Light plays an important role in ecological processes in the ocean both day and night. While relatively inexpensive, off the shelf instruments are available to measure Photosynthetically Active Radiation or PAR during the day, efforts to quantify light levels at night have proven more difficult. The goal of this work...

Age Structure Metrics for Precautionary Management: Can Simpler Assessment Techniques Save Fish, Time, and Money?

Creator:: Cusack, Christopher, Harte, Michael, Sylvia, Gil, Larkin, Sherry, and Heppell, Selina
Abstract:: Stock assessment techniques currently used in the United States are extremely costly to implement, involve significant data requirements, and are inaccessible to all but a few stock assessment scientists. A systematic decrease in fishery yields and the designation of several species as overfished on the west coast of the United...

Invasive bullfrog larvae lack developmental plasticity to changing hydroperiod

Creator:: Cook, Megan T., Heppell, Selina S., and Garcia, Tiffany S.
Abstract:: Determining the mechanisms responsible for the success of invasive species is critical for developing effective management strategies. Artificially draining managed wetlands to maintain natural ephemeral conditions is a common practice in the Pacific Northwest and is assumed to kill invasive American bullfrog (Lithobates catesbeianus) larvae, which typically overwinter in permanent...

The effects of temperature and predator densities on the consumption of walleye pollock (Gadus chalcogrammus) by three groundfish in the Gulf of Alaska

Creator:: Thompson, Kevin A., Heppell, Selina S., and Thompson, Grant G.
Abstract:: Many multispecies models have assumed that prey density determines per-capita predator consumption rates, following a functional response relationship. However, empirical evidence suggests that a predator’s diet can also be influenced by a variety of environmental factors, including interactions with other predators. We used diet and abundance data from National Marine...

A Proposed Framework for Identifying and Evaluating Ecosystem Service Tradeoffs for Marine Protected Area Planning

Creator:: Harte, Michael, Rosenberger, Randall, Sylvia, Gil, and Heppell, Selina
Abstract:: Existing research on the effectiveness of marine protected areas narrowly focuses on developing sets of management indicators tied to outcomes described in management plans or on the achievement of a single objective such as an increase in the size or number of older, more fecund female fish in a protected...

Advancing marine reserve science : from field experiments to marine conservation planning tools

Creator:: Leslie, Heather M.
Abstract:: This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...
