Multistate Mark-Recapture Analysis Reveals No Effect Of Blood Sampling On Survival And Recapture Of Eastern Kingbirds (Tyrannus Tyrannus), Lucas J. Redmond, Michael T. Murphy
Multistate Mark-Recapture Analysis Reveals No Effect Of Blood Sampling On Survival And Recapture Of Eastern Kingbirds (Tyrannus Tyrannus), Lucas J. Redmond, Michael T. Murphy

The experimentally supported and prevailing opinion is that blood sampling has few to no long-term effects on survival of birds when conducted properly, and blood sampling has become a vital addition to the toolbox of many ornithologists. However, many of the studies that concluded that blood sampling had negligible effects on birds used approaches that did not account for temporary emigration and probability of capture. To date, the only study to have done so found that blood sampling had a strong negative effect on survival. We conducted a mark–recapture analysis of 8 years of banding and bleeding data on Eastern …
Policy Analysis For Optimizing Native Fisheries On The Mckenzie River, Mary Ray
Policy Analysis For Optimizing Native Fisheries On The Mckenzie River, Mary Ray
Environmental Science and Management Professional Master's Project Reports
The impact of hatchery fish on native populations has been extensively studied, especially as environmental management has generally moved toward a conservation focus. In Oregon, the McKenzie River native rainbow trout population has been the focus of recent interest groups attempting to induce a change in management practices to support native fisheries. The McKenzie River Chapter of Trout Unlimited is interested in learning more about the impacts that hatchery stocked rainbow trout have on native river populations. It is the group's intent to seek a rule change to management by the Oregon Department of Fish and Wildlife. A review of …
The Aquarium Trade As An Invasion Pathway In The Pacific Northwest, Angela L. Strecker, Philip M. Campbell, Julian D. Olden
The Aquarium Trade As An Invasion Pathway In The Pacific Northwest, Angela L. Strecker, Philip M. Campbell, Julian D. Olden

The aquarium trade moves thousands of species around the globe, and unwanted organisms may be released into freshwaters, with adverse ecological and economic effects. We report on the first investigation of the ornamental pet trade as an invasion pathway in the Pacific Northwest region of the United States, where a moderate climate and a large human population present ample opportunities for the introduction and establishment of aquarium trade species. Results from a regional survey of pet stores found that the number of fish (n=400) and plant (n=124) species currently in the aquarium trade is vast. Pet stores import thousands of …
Population Structure Of Island-Associated Pantropical Spotted Dolphins (Stenella Attenuata) In Hawaiian Waters, Sarah Shelby Courbis
Population Structure Of Island-Associated Pantropical Spotted Dolphins (Stenella Attenuata) In Hawaiian Waters, Sarah Shelby Courbis
Dissertations and Theses
Understanding gene flow, diversity, and dispersal patterns is important for predicting effects of natural events and anthropogenic activities on dolphin populations. With the very recent exceptions of false killer whales (Pseudorca crassidens), spinner dolphins (Stenella longirostris), and common bottlenose dolphins (Tursiops truncatus), Hawaiian odontocete species are managed as single stocks within the U.S. Hawaiian Exclusive Economic Zone. These exceptions are a result of recent studies that have indicated that some species have populations that show fidelity to individual islands or groups of islands, resulting in genetic differentiation, often with management implications. The first part …
Using Archaeological Fish Remains To Determine The Native Status Of Anadromous Salmonids In The Upper Klamath Basin (Oregon, Usa) Through Mtdna And Geochemical Analysis, Alexander E. Stevenson
Using Archaeological Fish Remains To Determine The Native Status Of Anadromous Salmonids In The Upper Klamath Basin (Oregon, Usa) Through Mtdna And Geochemical Analysis, Alexander E. Stevenson
Dissertations and Theses
Within the Upper Klamath Basin, Oregon, the native status of anadromous salmonids (Oncorhynchus spp.) has been a long standing question. Ongoing efforts to establish if these fish were native to the region prior to the construction of the Copco I Dam on the Klamath River (c.1917) have relied on sparse, contradictory and sometimes unreliable historic documentation and informant testimony. Current restoration projects with very high financial and social costs necessitate accurate and reliable data on salmonid species which once called the region home. Often, archaeolofaunal remains present a novel way to determine species present in an area prior to …
Postfledging Survival And Habitat Use Of Spotted Towhees (Pipilo Maculatus) In An Urban Park, Amy Ann Shipley
Postfledging Survival And Habitat Use Of Spotted Towhees (Pipilo Maculatus) In An Urban Park, Amy Ann Shipley
Dissertations and Theses
Habitat fragmentation, and the resulting increase in edge habitat, has important effects on birds, including the increased probability of nest predation, changes in habitat structure, and the increased presence of non-native plant species. It is critical to understand the effects of fragmentation at all stages of the avian life cycle, including the often overlooked postfledging period. Because much of juvenile mortality occurs during the immediate postfledging period, and juvenile mortality contributes substantially to population dynamics, it is necessary to understand if fledgling survival is reduced in edge habitats and if fledglings' survival is influenced by their habitat use. During 2008 …
