Long-Term Citizen-Collected Data Reveal Geographical Patterns and Temporal Trends in Lake Water Clarity

Creator:: Lottig, Noah R., Wagner, Tyler, Norton Henry, Emily, Spence Cheruvelil, Kendra, Webster, Katherine E., Downing, John A., and Stow, Craig A.
Abstract:: We compiled a lake-water clarity database using publically available, citizen volunteer observations made between 1938 and 2012 across eight states in the Upper Midwest, USA. Our objectives were to determine (1) whether temporal trends in lake-water clarity existed across this large geographic area and (2) whether trends were related to...

LintzHeatherCEOASEvidenceTreeSpecies.pdf

Creator:: Monleon, Vicente J. and Lintz, Heather E.
Abstract:: Climate change is expected to change the distribution of species. For long-lived, sessile species such as trees, tracking the warming climate depends on seedling colonization of newly favorable areas. We compare the distribution of seedlings and mature trees for all but the rarest tree species in California, Oregon and Washington,...

Creator:: Schoebel, Corine N., Stewart, Jane, Gruenwald, Niklaus J., Rigling, Daniel, and Prospero, Simone
Abstract:: Human activity has been shown to considerably affect the spread of dangerous pests and pathogens worldwide. Therefore, strict regulations of international trade exist for particularly harmful pathogenic organisms. Phytophthora plurivora, which is not subject to regulations, is a plant pathogen frequently found on a broad range of host species, both...

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...

Creator:: Danies, Giovanna, Myers, Kevin, Mideros, Maria F., Grünwald, Niklaus J., and et al.
Abstract:: Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...

AverettNonNativePlantInvasion.PDF

Creator:: Averett, Joshua P., McCune, Bruce, Parks, Catherine G., Naylor, Bridgett J., DelCurto, Tim, and Mata-González, Ricardo
Abstract:: Mountain environments are currently among the ecosystems least invaded by non-native species; however, mountains are increasingly under threat of non-native plant invasion. The slow pace of exotic plant invasions in mountain ecosystems is likely due to a combination of low anthropogenic disturbances, low propagule supply, and extreme/steep environmental gradients. The...
