Uncertainty analysis: an evaluation metric for synthesis science

Creator:: Harmon, Mark E., Fasth, Becky, Halpern, Charles B., and Lutz, James A.
Abstract:: The methods for conducting reductionist ecological science are well known and widely used. In contrast, those used in the synthesis of ecological science (i.e., synthesis science) are still being developed, vary widely, and often lack the rigor of reductionist approaches. This is unfortunate because the synthesis of ecological parts into...

The relative contribution of climate to changes in lesser prairie-chicken abundance

Creator:: Ross, Beth E., Haukos, David, Hagen, Christian, and Pitman, James
Abstract:: Managing for species using current weather patterns fails to incorporate the uncertainty associated with future climatic conditions; without incorporating potential changes in climate into conservation strategies, management and conservation efforts may fall short or waste valuable resources. Understanding the effects of climate change on species in the Great Plains of...

Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:: Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.
Abstract:: Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...

Identifying Potential Mechanisms Enabling Acidophily in the Ammonia-Oxidizing Archaeon "Candidatus Nitrosotalea devanaterra"

Creator:: Lehtovirta-Morley, Laura E., Sayavedra-Soto, Luis A., Gallois, Nicolas, Schouten, Stefan, Stein, Lisa Y., Prosser, James I., and Nicol, Graeme W.
Abstract:: Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has...

Genetic and Functional Diversification of Small RNA Pathways in Plants

Creator:: Xie, Zhixin, Johansen, Lisa K., Gustafan, Adam M., Kasschau, Kristin D., Lellis, Andrew D., Zilberman, Daniel, Jacobsen, Steven E., and Carrington, James C.
Abstract:: Multicellular eukaryotes produce small RNA molecules (approximately 21–24 nucleotides) of two general types, microRNA (miRNA) and short interfering RNA (siRNA). They collectively function as sequence-specific guides to silence or regulate genes, transposons, and viruses and to modify chromatin and genome structure. Formation or activity of small RNAs requires factors belonging...

The ERI-6/7 Helicase Acts at the First Stage of an siRNA Amplification Pathway That Targets Recent Gene Duplications

Creator:: Fischer, Sylvia E. J., Montgomery, Taiowa A., Zhang, Chi, Fahlgren, Noah, Breen, Peter C., Hwang, Alexia, Sullivan, Christopher M., Carrington, James C., and Ruvkun, Gary
Abstract:: Endogenous small interfering RNAs (siRNAs) are a class of naturally occuring regulatory RNAs found in fungi, plants, and animals. Some endogenous siRNAs are required to silence transposons or function in chromosome segregation; however, the specific roles of most endogenous siRNAs are unclear. The helicase gene eri-6/7 was identified in the...

Eocene and not Cretaceous origin of spider wasps: Fossil evidence from amber

Creator:: Rodriguez, Juanita, Waichert, Cecilia, von Dohlen, Carol D., Poinar, George, Jr., and Pitts, James P.
Abstract:: Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...

Predation on an Upper Trophic Marine Predator, the Steller Sea Lion: Evaluating High Juvenile Mortality in a Density Dependent Conceptual Framework

Creator:: Horning, Markus and Mellish, Jo-Ann E.
Abstract:: The endangered western stock of the Steller sea lion (Eumetopias jubatus) - the largest of the eared seals - has declined by 80% from population levels encountered four decades ago. Current overall trends from the Gulf of Alaska to the Aleutian Islands appear neutral with strong regional heterogeneities. A published...

Historical Biogeography and Diversification of Truffles in the Tuberaceae and Their Newly Identified Southern Hemisphere Sister Lineage

Creator:: Bonito, Gregory, Smith, Matthew E., Nowak, Michael, Healy, Rosanne A., Guevara, Gonzalo, Cazares, Efren, Kinoshita, Akihiko, Nouhra, Eduardo R., Domınguez, Laura S., Tedersoo, Leho, Murat, Claude, Wang, Yun, Arroyo Moreno, Baldomero, Pfister, Donald H., Nara, Kazuhide, Zambonelli, Alessandra, Trappe, James M., and Vilgalys, Rytas
Abstract:: Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...
