Fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits in the California Current Ecosystem

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: Dynamic marine environments can shape complex spatial and temporal patterns in the population connectivity of marine species, and this is often exemplified in species with long larval phases.

Evidence for mate selection in captive-breeding rockfishes (genus Sebastes): inference from parentage analysis and the major histocompatibility complex (MHC)

Creator:: Johansson, M. L., Clifford, K., Fodness, B., Vazquez, N. A., and Banks, M. A.
Abstract:: Rockfish species of the genus Sebastes are notable for being numerous and diverse. Rockfishes are unusual among fish because they fertilize their eggs internally and release live, swimming larvae. They undergo complex courting behaviors, which may allow females to be selective about their mates. The major histocompatibility complex (MHC) has...

For species that inhabit both the coastal ocean and partially enclosed water bodies (i.e., estuaries or fjords), this information is even more critical since estuaries and fjords are often characterized by hydrological complexities...

Columbia River plume fronts. II. Distribution, abundance, and feeding ecology of juvenile salmon

Creator:: De Robertis, Alex, Morgan, Cheryl A., Schabetsberger, Robert A., Zabel, Richard W., Brodeur, Richard D., Emmett, Robert L., Knight, Carolyn M., Krutzikowsky, Gregory K., and Casillas, Edmundo
Abstract:: Well-defined fronts develop at the seaward edge of riverine plumes where suspended materials and planktonic organisms are concentrated by convergent water flows. Riverine plume fronts have been hypothesized to be favorable fish habitats because they can lead to localized prey aggregations. We examined the spatial distribution of juvenile Pacific salmonids...

Cold front induced changes on the Florida panhandle shelf during October 2008

Creator:: Kamykowski, D., Morrison, J. M., McCulloch, A. A., Nyadjro, E. S., Thomas, C. A., Sinclair, G. A., and Grabowski Pridgen, K.
Abstract:: A significant step transition between seasonally stratified and destratified hydrographic conditions occurred during an October 2008 cruise to the Florida Panhandle Shelf along a cross-shelf transect that was sampled before and after a cold front passed through the area. Meteorological measurements from nearby ocean and land-based stations characterized the event....

Closing report for the Coastal stream improvement and rehabilitation program authorized by Chapter 527, Oregon laws, 1961

Creator:: Summers, Virgil C., Neubauer, Edward K., and Oregon. Fish Commission
Abstract:: "The natural production of anadromous fish in many coastal streams has been seriously reduced by pollution, dams, timber harvesting, siltation, and other such forces. Many miles of streams that could be in production are not available to anadromous fish because access is blocked by log jams or natural barriers such...

Climate shifts the interaction web of a marine plankton community

Creator:: Francis, Tessa B., Scheuerell, Mark D., Brodeur, Richard D., Levin, Phillip S., Ruzicka, James J., Tolimieri, Nick, and Peterson, William T.
Abstract:: Climatic effects in the ocean at the community level are poorly described, yet accurate predictions about ecosystem responses to changing environmental conditions rely on understanding biotic responses in a food-web context to support knowledge about direct biotic responses to the physical environment. Here we conduct time-series analyses with multivariate autoregressive...

Classification of Animal Movement Behavior through Residence in Space and Time

Creator:: Orben, Rachael A., Thompson, David R., Tolkova, Irina, and Torres, Leigh G.
Abstract:: Identification and classification of behavior states in animal movement data can be complex, temporally biased, time-intensive, scale-dependent, and unstandardized across studies and taxa. Large movement datasets are increasingly common and there is a need for efficient methods of data exploration that adjust to the individual variability of each track. We...

Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Characterizing neutral and adaptive genomic differentiation in a changing climate: The most northerly freshwater fish as a model

Creator:: O'Malley, Kathleen G., Vaux, Felix, and Black, Andrew N.
Abstract:: Arctic freshwater ecosystems have been profoundly affected by climate change. Given that the Arctic charr (Salvelinus alpinus) is often the only fish species inhabiting these ecosystems, it represents a valuable model for studying the impacts of climate change on species life‐history diversity and adaptability. Using a genotyping‐by‐se‐ quencing approach, we...

Abstract:: The goal of this study was to describe the duration and magnitude of the physiological stress response in lingcod Ophiodon elongatus after exposure to brief handling and sublethal air stressors. The response to these stressors was determined during a 24‐h recovery period by measuring concentrations of plasma cortisol, lactate, glucose,...

Abstract:: Protein profiles and serological characteristics of 3 rhabdoviruses from snakehead fish Ophicephalus striatus were determined and compared to 5 known fish rhabdoviruses and 1 mammalian rhabdovirus. The snakehead rhabdovirus (SHRV) exhibited a bacilliform morphology and a Lyssavirus-type protein profile. The ulcerative disease rhabdovirus isolates (UDRV-BP and UDRV-19) were indistinguishable and...

Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Creator:: Weitkamp, Laurie A.
Abstract:: One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....

Buoyancy regulation and barotrauma in two species of nearshore rockfish

Creator:: Parker, Steven J., McElderry, Howard I., Rankin, Polly S., and Hannah, Robert W.
Abstract:: Fishes with closed swim bladders regulate buoyancy during depth changes by secreting and resorbing swim bladder gases. Forced ascent during fishery capture results in barotrauma caused by rapid expansion and exsolution of gases from body fluids. Pressure changes in hyperbaric chambers were used to examine changes in swim bladder integrity...
