Fish-habitat associations on a deep reef at the edge of the Oregon continental shelf

Creator:: Tissot, Brian N., Hixon, Mark Anthony, Barss, William, and Stein, David L.
Abstract:: Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...

Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Mapping the Global Emergence of Batrachochytrium dendrobatidis, the Amphibian Chytrid Fungus

Creator:: Olson, Deanna H., Aanensen, David M., Ronnenberg, Kathryn L., Powell, Christopher I., Walker, Susan F., Bielby, Jon, Garner, Trenton W. J., Weaver, George, The Bd Mapping Group, and Fisher, Matthew C.
Abstract:: The rapid worldwide emergence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) is having a profound negative impact on biodiversity. However, global research efforts are fragmented and an overarching synthesis of global infection data is lacking. Here, we provide results from a community tool for the compilation of worldwide Bd presence...

Differences in Adélie Penguin (Pygoscelis adeliae) Chick Growth Rates and Diet

Creator:: Jennings, Scott, Varsani, Arvind, Dugger, Katie M., Ballard, Grant, and Ainley, David G.
Abstract:: Sexually size-dimorphic species must show some difference between the sexes in growth rate and/or length of growing period. Such differences in growth parameters can cause the sexes to be impacted by environmental variability in different ways, and understanding these differences allows a better understanding of patterns in productivity between individuals...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...

Excited state structural dynamics of a dual-emission calmodulingreen fluorescent protein sensor for calcium ion imaging

Creator:: Oscar, Breland G., Liu, Weimin, Zhao, Yongxin, Tang, Longteng, Wang, Yanli, Campbell, Robert E., and Fang, Chong
Abstract:: Fluorescent proteins (FPs) have played a pivotal role in bioimaging and advancing biomedicine. The versatile fluorescence from engineered, genetically encodable FP variants greatly enhances cellular imaging capabilities, which are dictated by excited state structural dynamics of the embedded chromophore inside the protein pocket. Visualization of the molecular choreography of the...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:: Pearcy, William G. and Fisher, Joseph P.
Abstract:: We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...

A Numerical Examination of ¹⁴CO₂ Chamber Methodologies for Sampling at the Soil Surface

Creator:: Egan, Jocelyn, Nickerson, Nick, Phillips, Claire, and Risk, Dave
Abstract:: Radiocarbon is an exceptionally useful tool for studying soil-respired CO₂, providing information about soil carbon turnover rates, depths of production, and the biological sources of production through partitioning. Unfortunately, little work has been done to thoroughly investigate the possibility of inherent biases present in current measurement techniques, like those present...

The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

Creator:: Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
Abstract:: Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

ARK: Aggregation of Reads by K-Means for Estimation of Bacterial Community Composition

Creator:: Koslicki, David, Chatterjee, Saikat, Shahrivar, Damon, Walker, Alan W., Francis, Suzanna C., Fraser, Louise J., Vehkaperä, Mikko, Lan, Yueheng, and Corander, Jukka
Abstract:: Motivation: Estimation of bacterial community composition from high-throughput sequenced 16S rRNA gene amplicons is a key task in microbial ecology. Since the sequence data from each sample typically consist of a large number of reads and are adversely impacted by different levels of biological and technical noise, accurate analysis of...
