Production of Ceratonova shasta Myxospores from Salmon Carcasses: Carcass Removal Is Not a Viable Management Option

Creator:: Foott, J. S., Stone, R., Fogerty, R., True, K., Bolick, A., Bartholomew, J. L., Hallett, S. L., Buckles, G. R., and Alexander, J. D.
Abstract:: Severe infection by the endemic myxozoan parasite, Ceratonova (synonym, Ceratomyxa) shasta, has been associated with declines in and impaired recovery efforts of populations of fall-run Chinook Salmon Oncorhynchus tshawytscha in the Klamath River, California. The parasite has a complex life cycle involving a polychaete worm host as well as a...

Density of the Waterborne Parasite Ceratomyxa shasta and Its Biological Effects on Salmon

Creator:: Hallett, Sascha L., Ray, R. Adam, Hurst, Charlene N., Holt, Richard A., Buckles, Gerri R., Atkinson, Stephen D., and Bartholomew, Jerri L.
Abstract:: The myxozoan parasite Ceratomyxa shasta is a significant pathogen of juvenile salmonids in the Pacific Northwest of North America and is limiting recovery of Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon populations in the Klamath River. We conducted a 5-year monitoring program that comprised concurrent sentinel fish exposures and...

Ice nucleation processes in upper tropospheric wave-clouds observed during SUCCESS

Creator:: Jensen, E. J., Toon, O. B., Tabazadeh, A., Sachse, G. W., Andersen, B. E., Chan, K. R., Twohy, Cynthia, Gandrud, Bruce W., Aulenbach, S. M., Heymsfield, Andrew J., Hallett, J., and Gary, B.
Abstract:: We have compared in situ measurements near the leading-edges of wave-clouds observed during the SUCCESS experiment with numerical simulations. Observations of high supersaturations with respect to ice (> 50%) near the leading edge of a very cold wave cloud (T < -60°C) are approximately consistent with recent theoretical and laboratory...

The origin and significance of crystal rich inclusions in pumices from two Chilean ignimbrites

Creator:: de Silva, S. L.
Abstract:: Crystal rich (~ 70–98% phenocrysts) magmatic inclusions in pumices for compositionally heterogeneous ignimbrites from the Central Andes of northern Chile are interpreted as the products of crystal accretion at the sidewalls of the magma chambers. The inclusions are typically andesitic in composition and are found as ‘peppery textured’ lenses and...

Managing the whole landscape: historical, hybrid, and novel ecosystems

Creator:: Hobbs, Richard J., Higgs, Eric, Hall, Carol M., Bridgewater, Peter, Chapin, F. Stuart, III, Ellis, Erle C., Ewel, John J., Hallett, Lauren M., Harris, James, Hulvey, Kristen B., Jackson, Stephen T., Kennedy, Patricia L., Kueffer, Christoph, Lach, Lori, Lantz, Trevor C., Lugo, Ariel E., Mascaro, Joseph, Murphy, Stephen D., Nelson, Cara R., Perring, Michael P., Richardson, David M., Seastedt, Timothy R., Standish, Rachel J., Starzomski, Brian M., Suding, Katherine N., Tognetti, Pedro M., Yakob, Laith, and Yung, Laurie
Abstract:: The reality confronting ecosystem managers today is one of heterogeneous, rapidly transforming landscapes, particularly in the areas more affected by urban and agricultural development. A landscape management framework that incorporates all systems, across the spectrum of degrees of alteration, provides a fuller set of options for how and when to...

Creator:: Atkinson, S. D., Foott, J. S., and Bartholomew, J. L.
Abstract:: Ceratonova gasterostea n. gen. n. sp. is described from the intestine of freshwater Gasterosteus aculeatus L. from the Klamath River, California. Myxospores are arcuate, 22.4 +/- 2.6 μm thick, 5.2 +/- 0.4 μm long, posterior angle 45 +/- 24°, with 2 sub-spherical polar capsules, diameter 2.3 +/- 0.2 μm, which...
