Post-Breeding Season Migrations of a Top Predator, the Harbor Seal (Phoca vitulina richardii), from a Marine Protected Area in Alaska

Creator:: Womble, Jamie N. and Gende, Scott M.
Abstract:: Marine protected areas (MPAs) are increasingly being used as a conservation tool for highly mobile marine vertebrates and the focus is typically on protecting breeding areas where individuals are aggregated seasonally. Yet movements during the non-breeding season can overlap with threats that may be equally as important to population dynamics....

Carbon Stocks of Tropical Coastal Wetlands within the Karstic Landscape of the Mexican Caribbean

Creator:: Kauffman, J. Boone, Medina, Israel, Gamboa, Julieta N., Torres, Olmo, Caamal, Juan P., Reza, Miriam, Herrera-Silveira, Jorge A., and Adame, Maria Fernanda
Abstract:: Coastal wetlands can have exceptionally large carbon (C) stocks and their protection and restoration would constitute an effective mitigation strategy to climate change. Inclusion of coastal ecosystems in mitigation strategies requires quantification of carbon stocks in order to calculate emissions or sequestration through time. In this study, we quantified the...

Phylogenetic and morphometric analysis of speckled dace (Rhinichthys osculus) from Oregon's Great Basin

Creator:: Hoekzema, Kendra L.
Abstract:: Speckled dace (Rhinichthys osculus) is a small cyprinid that is geographically widespread throughout western North America, and the most frequently occurring sh in Oregon. Because of the genetic and morphological variation in this species across its range, it has been referred to as a "species complex" and no revision to...

Climate Change Winners: Receding Ice Fields Facilitate Colony Expansion and Altered Dynamics in an Adélie Penguin Metapopulation

Creator:: LaRue, Michelle A., Ainley, David G., Swanson, Matt, Dugger, Katie M., Lyver, Phil O'B., Barton, Kerry, and Ballard, Grant
Abstract:: There will be winners and losers as climate change alters the habitats of polar organisms. For an Adelie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a cluster of colonies in the southern Ross Sea, we report a recent population increase in response to increased nesting habitat as...

Reproductive success and foraging ecology of the rusty blackbird on the Copper River Delta, Alaska

Creator:: Loomis, David M.
Abstract:: The Rusty Blackbird (Euphagus carolinus) has suffered significant population declines across its entire geographic range and the mechanisms associated with this decline are poorly understood. Although much of the Rusty Blackbird breeding habitat in Alaska has remained relatively unaltered by anthropogenic activities, this species continues to decline by an estimated...

Assessment of the quantitative fluorescent antibody technique and chemotherapy for the detection and control of Renibacterium salmoninarum in salmonid fishes

Creator:: Drongesen, Jeffrey Edward
Abstract:: Detection and treatment of bacterial kidney disease (BKD) was investigated. Experiments were conducted to evaluate the quantitative, fluorescent antibody technique (QFAT) that is used to detect, identify, and quantify both typical and 'bar form' Renibacterium salmoninarum cells. Smears of kidney tissue from naturally and artificially infected salmonids, both with and...

Effects of inbreeding Coho salmon (oncorhynchus kisutch)

Creator:: Solazzi, M. F. (Mario Frank)
Abstract:: Effects of inbreeding coho salmon (Oncorhynchus kisutch) on survival during early life history, growth, feed efficiency, and resistance to gas bubble disease were studied. No effect of inbreeding could be associated with either F=0.25 or F=0.125. Tetraploidy may help explain the absence of inbreeding depression at these levels.

Status and habitat preference of California bighorn sheep on Sheldon National Wildlife Refuge, Nevada

Creator:: Hansen, Michael Charles
Abstract:: A herd of California bighorn sheep (Ovis canadensis californiana), re-introduced to the area of Hell Creek on the Sheldon National Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978 to 20 August 1980. Major vegetation and physiographic types were delineated and described. Habitat preferences were determined from field...

Dynamics of a recovering Arctic bird population: the importance of climate, density dependence, and site quality

Creator:: Bruggeman, Jason E., Swem, Ted, Andersen, David E., Kennedy, Patricia L., and Nigro, Debora
Abstract:: Intrinsic and extrinsic factors affect vital rates and population-level processes, and understanding these factors is paramount to devising successful management plans for wildlife species. For example, birds time migration in response, in part, to local and broadscale climate fluctuations to initiate breeding upon arrival to nesting territories, and prolonged inclement...

Large-scale macroinvertebrate assemblage patterns from least-disturbed wadeable stream sites across the 48 contiguous US states

Creator:: Gerth, W. J., Herlihy, A. T., and Sifneos, J. C.
Abstract:: We quantified the patterns in macroinvertebrate assemblages and their associated environmental gradients from 457 least-disturbed wadeable stream sites across the 48 contiguous United States sampled as part of US EPA’s National Wadeable Stream Assessment. The majority of the variation in assemblage composition at the finest taxonomic resolution was related to...
