Local Variability Mediates Vulnerability of Trout Populations to Land Use and Climate Change

Creator:: Penaluna, Brooke E., Dunham, Jason B., Railsback, Steve F., Arismendi, Ivan, Johnson, Sherri L., Bilby, Robert E., Safeeq, Mohammad, and Skaugset, Arne E.
Abstract:: Land use and climate change occur simultaneously around the globe. Fully understanding their separate and combined effects requires a mechanistic understanding at the local scale where their effects are ultimately realized. Here we applied an individual-based model of fish population dynamics to evaluate the role of local stream variability in...

Phytophthora Have Distinct Endogenous Small RNA Populations That Include Short Interfering and microRNAs

Creator:: Fahlgren, Noah, Bollmann, Stephanie R., Kasschau, Kristin D., Cuperus, Josh T., Press, Caroline M., Sullivan, Christopher M., Chapman, Elisabeth J., Hoyer, J. Steen, Gilbert, Kerrigan B., Grunwald, Niklaus J., and Carrington, James C.
Abstract:: In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements. RNA silencing was likely present in the common ancestor of modern eukaryotes, but most research has focused on plant and animal RNA silencing systems. Phytophthora...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Characteristics of Settling Coral Reef Fish Are Related to Recruitment Timing and Success

Creator:: Rankin, Tauna L. and Sponaugle, Su
Abstract:: Many marine populations exhibit high variability in the recruitment of young into the population. While environmental cycles and oceanography explain some patterns of replenishment, the role of other growth-related processes in influencing settlement and recruitment is less clear. Examination of a 65-mo. time series of recruitment of a common coral...

Increasing synchrony of high temperature and low flow in western North American streams: double trouble for coldwater biota?

Creator:: Arismendi, Ivan, Safeeq, Mohammad, Johnson, Sherri L., Dunham, Jason B., and Haggerty, Roy
Abstract:: Flow and temperature are strongly linked environmental factors driving ecosystem processes in streams. Stream temperature maxima (T [subscript max_w]) and stream flow minima (Q[subscript min]) can create periods of stress for aquatic organisms. In mountainous areas, such as western North America, recent shifts toward an earlier spring peak flow and...

Distribution of Potato virus Y Strains in Tubers during the Post-Harvest Period

Creator:: Whitworth, Jonathan L., Hamm, Philip B., and Nolte, Phillip
Abstract:: Russet Burbank, Russet Norkotah, and Shepody tubers infected with Potato virus Y strains (PVYO, PVYN:O, PVYNTN) were tested from storage at 4A degrees C at the initiation of sprouting and then the same tubers were tested again from storage at 4A degrees C seventy eight days later. Samples were taken...

Can parasites halt the invader? Mermithid nematodes parasitizing the yellow-legged Asian hornet in France

Creator:: Villemant, Claire, Zuccon, Dario, Rome, Quentin, Muller, Franck, Poinar, George O., Jr., and Justine, Jean-Lou
Abstract:: Since its introduction in France 10 years ago, the yellow-legged Asian bee-hawking hornet Vespa velutina has rapidly spread to neighboring countries (Spain, Portugal, Belgium, Italy, and Germany), becoming a new threat to beekeeping activities. While introduced species often leave behind natural enemies from their original home, which benefits them in...

United States Forest Disturbance Trends Observed Using Landsat Time Series

Creator:: Masek, Jeffrey G., Goward, Samuel N., Kennedy, Robert E., Cohen, Warren B., Moisen, Gretchen G., Schleeweis, Karen, and Huang, Chengquan
Abstract:: Disturbance events strongly affect the composition, structure, and function of forest ecosystems; however, existing US land management inventories were not designed to monitor disturbance. To begin addressing this gap, the North American Forest Dynamics (NAFD) project has examined a geographic sample of 50 Landsat satellite image time series to assess...

Ocean wavenumber estimation from wave-resolving time series imagery

Creator:: Plant, Nathaniel G., Holland, K. Todd, and Haller, Merrick C.
Abstract:: We review several approaches that have been used to estimate ocean surface gravity wavenumbers from wave-resolving remotely sensed image sequences. Two fundamentally different approaches that utilize these data exist. A power spectral density approach identifies wavenumbers where image intensity variance is maximized. Alternatively, a cross-spectral correlation approach identifies wavenumbers where...
