Prey selection by the tropical marine snail Thais melones : a study of the effects of interindividual variation and foraging experience on growth and gonad development

Creator:: West, Lani
Abstract:: I studied the feeding behavior of marked individuals of the carnivorous marine snail Thais melones in a rocky shore habitat of Pacific Panama. The population of snails consume a variety of invertebrate species such as bivalves, limpets, and polychaetes. Individuals exhibited a range of diet breadth, with some specialized, but...

Polygyny in the bobolink : habitat quality and the adaptive complex

Creator:: Martin, Stephen George, 1941-
Abstract:: The adaptiveness of polygyny in passerines poses a particularly intriguing problem. The altricial young of this group require extended parental care, but young of polygynous pairings generally lack the undivided attention of the male which young of monogamous pairings receive. Polygynous offspring may thus be undernourished and experience greater mortality....

Sea urchin eggs, Calcium and magnesium flux in dividing sea urchin eggs

Creator:: Kleinschuster, Stephen John
Abstract:: This study was initiated to determine the concentration of magnesium and calcium in dividing eggs of the sea urchin Stroncavocentrotus purpuratus and to explore the relationship between these ions and mitotic events. Samples of developing eggs, maintained at 15°C, were taken at ten-minute intervals from fertilization through the second cleavage,...

Assessing the Health of the U.S. West Coast with a Regional-Scale Application of the Ocean Health Index

Creator:: Halpern, Benjamin S., Longo, Catherine, Scarborough, Courtney, Hardy, Darren, Best, Benjamin D., Doney, Scott C., Katona, Steven K., McLeod, Karen L., Rosenberg, Andrew A., and Samhouri, Jameal F.
Abstract:: Management of marine ecosystems increasingly demands comprehensive and quantitative assessments of ocean health, but lacks a tool to do so. We applied the recently developed Ocean Health Index to assess ocean health in the relatively data-rich US west coast region. The overall region scored 71 out of 100, with sub-regions...

The ecological and behavioral dynamics of breeding in three sympatric anuran amphibians

Creator:: Olson, Deanna H.
Abstract:: Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...

Catching the Right Wave: Evaluating Wave Energy Resources and Potential Compatibility with Existing Marine and Coastal Uses

Creator:: Kim, Choong-Ki, Toft, Jodie E., Papenfus, Michael, Verutes, Gregory, Guerry, Anne D., Ruckelshaus, Marry H., Arkema, Katie K., Guannel, Gregory, Wood, Spencer A., Bernhardt, Joanna R., Tallis, Heather, Plummer, Mark L., Halpern, Benjamin S., Pinsky, Malin L., Beck, Michael W., Chan, Francis, Chan, Kai M. A., Levin, Phil S., and Polasky, Stephen
Abstract:: Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows 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...

Chemical signaling and pheromone evolution in plethodontid salamanders

Creator:: Palmer, Catherine Anne
Abstract:: My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....
