Invasive bullfrog use of novel ephemeral habitats in the Pacific Northwest

Creator:: Cook, Megan Tetsuko
Abstract:: Invasive species are a major threat to global biodiversity. Understanding the mechanisms underlying successful invasions is imperative for developing effective management strategies. Plasticity in physiological, morphological, and behavioral traits could be an indicator of invasion potential in non-native species. The invasive American bullfrog (Lithobates catesbeianus) has recently been observed breeding...

Accounting for Transient Dynamics Improves use of Marine Protected Areas as a Reference Point for Fisheries Management

Creator:: Quennessen, Victoria I.
Abstract:: Fisheries management that is based on quantitative assessment has commonly relied on estimating the unfished biomass of a fished stock to compare current and historical population size. Developing predictive models for this requires many years of catch and abundance data. Smaller, new, or mainly recreational fisheries may not have the...

Structure, abundance, and distribution of pelagic zooplankton in a deep, oligotrophic Caldera Lake

Creator:: Karnaugh, Elena N.
Abstract:: From July 1985 to April 1987 the pelagic zooplankton community of Crater Lake, Oregon was studied to determine taxonomic structure, absolute and relative densities, and spatial and temporal distributional patterns. Samples were collected using vertically-towed zooplankton nets. The community structure consisted of two cladoceran and nine rotifer species, which were...

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...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

Effect of adult aquatic insect life history on return to Lookout Creek, H. J. Andrews Experimental Forest, Oregon

Creator:: Farrand, Alexander Mark
Abstract:: Aquatic insects that emerge out of streams to mate represent a potential energy flux to terrestrial food webs. The relative success of an individual aquatic adult insect is whether it survives long enough to produce offspring, i.e. mate and return to the stream to oviposit eggs. Some characteristics of the...

An Integrated Approach to the Investigation of Age, Growth and Population Dynamics of Burrowing Thalassinidean Shrimps in a U.S. West Coast Estuary

Creator:: Bosley, Katelyn Marie
Abstract:: Two indigenous species of burrowing shrimp inhabit and often dominate the intertidal zone of estuaries along the US West Coast, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species are considered ecosystem engineers and play a role in maintaining estuarine health and ecosystem function. They...

Utilization of dietary protein by the mussel, Mytilus edulis trossulus (Linnaeus 1758)

Creator:: Kreeger, Daniel A.
Abstract:: Protein microcapsules (PM) were developed as a tool for investigating aspects of dietary protein utilization by mussels, Mytilus edulis trossulus. Digestion of PM in vitro by protease, trypsin, amylase and extracts from the gut of mussels varied significantly depending on the type of protein encapsulated or whether carbohydrates were added...
