Re-Occupancy of Breeding Territories by Ferruginous Hawks in Wyoming: Relationships to Environmental and Anthropogenic Factors

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Oakleaf, Robert J., Olson, Lucretia E., and Dugger, Katie M.
Abstract:: Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...

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...

Climate Change Winners: Receding Ice Fields Facilitate Colony Expansion and Altered Dynamics in an Adélie Penguin Metapopulation

Creator:: LaRue, Michelle A., Ainley, David G., Swanson, Matt, Dugger, Katie M., Lyver, Phil O'B., Barton, Kerry, and Ballard, Grant
Abstract:: There will be winners and losers as climate change alters the habitats of polar organisms. For an Adelie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a cluster of colonies in the southern Ross Sea, we report a recent population increase in response to increased nesting habitat as...

Current and Future Land Use around a Nationwide Protected Area Network

Creator:: Hamilton, Christopher M., Martinuzzi, Sebastian, Plantinga, Andrew J., Radeloff, Volker C., Lewis, David J., Thogmartin, Wayne E., Heglund, Patricia J., and Pidgeon, Anna M.
Abstract:: Land-use change around protected areas can reduce their effective size and limit their ability to conserve biodiversity because land-use change alters ecological processes and the ability of organisms to move freely among protected areas. The goal of our analysis was to inform conservation planning efforts for a nationwide network of...

Infection of Brachypodium distachyon by Formae Speciales of Puccinia graminis: Early Infection Events and Host-Pathogen Incompatibility

Creator:: Figueroa, Melania, Alderman, Stephen, Garvin, David F., and Pfender, William F.
Abstract:: Puccinia graminis causes stem rust, a serious disease of cereals and forage grasses. Important formae speciales of P. graminis and their typical hosts are P. graminis f. sp. tritici (Pg-tr) in wheat and barley, P. graminis f. sp. lolii (Pg-lo) in perennial ryegrass and tall fescue, and P. graminis f....

Identification of Genetic Variation between Obligate Plant Pathogens Pseudoperonospora cubensis and P-humuli Using RNA Sequencing and Genotyping-By-Sequencing

Creator:: Summers, Carly F., Gulliford, Colwyn M., Carlson, Craig H., Lillis, Jacquelyn A., Carlson, Maryn O., Cadle-Davidson, Lance, Gent, David H., and Smart, Christine D.
Abstract:: RNA sequencing (RNA-seq) and genotyping-by-sequencing (GBS) were used for single nucleotide polymorphism (SNP) identification from two economically important obligate plant pathogens, Pseudoperonospora cubensis and P. humuli. Twenty isolates of P. cubensis and 19 isolates of P. humuli were genotyped using RNA-seq and GBS. Principle components analysis (PCA) of each data...

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...

Analysis of Genome Sequences from Plant Pathogenic Rhodococcus Reveals Genetic Novelties in Virulence Loci

Creator:: Creason, Allison L., Vandeputte, Olivier M., Savory, Elizabeth A., Davis, Edward W., II, Putnam, Melodie L., Hu, Erdong, Swader-Hines, David, Mol, Adeline, Baucher, Marie, Prinsen, Els, Zdanowska, Magdalena, Givan, Scott A., El Jaziri, Mondher, Loper, Joyce E., Mahmud, Taifo, and Chang, Jeff H.
Abstract:: Members of Gram-positive Actinobacteria cause economically important diseases to plants. Within the Rhodococcus genus, some members can cause growth deformities and persist as pathogens on a wide range of host plants. The current model predicts that phytopathogenic isolates require a cluster of three loci present on a linear plasmid, with...

Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.
Abstract:: Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...

Warming Ocean Conditions Relate to Increased Trophic Requirements of Threatened and Endangered Salmon

Creator:: Daly, Elizabeth A. and Brodeur, Richard D.
Abstract:: The trophic habits, size and condition of yearling Chinook salmon (Oncorhynchus tshawytscha) caught early in their marine residence were examined during 19 survey years (1981–1985; 1998–2011). Juvenile salmon consumed distinct highly piscivorous diets in cold and warm ocean regimes with major differences between ocean regimes driven by changes in consumption...
