Mapping Migratory Bird Prevalence Using Remote Sensing Data Fusion

Creator:: Swatantran, Anu, Dubayah, Ralph, Goetz, Scott, Hofton, Michelle, Betts, Matthew G., Sun, Mindy, Simard, Marc, and Holmes, Richard
Abstract:: Background: Improved maps of species distributions are important for effective management of wildlife under increasing anthropogenic pressures. Recent advances in lidar and radar remote sensing have shown considerable potential for mapping forest structure and habitat characteristics across landscapes. However, their relative efficacies and integrated use in habitat mapping remain largely...

Temporal Genetic Variance and Propagule-Driven Genetic Structure Characterize Naturalized Rainbow Trout (Oncorhynchus mykiss) from a Patagonian Lake Impacted by Trout Farming

Creator:: Benavente, Javiera N., Seeb, Lisa W., Seeb, James E., Arismendi, Ivan, Hernández, Cristián E., Gajardo, Gonzalo, Galleguillos, Ricardo, Cádiz, Maria I., Musleh, Selim S., and Gomez-Uchida, Daniel
Abstract:: Knowledge about the genetic underpinnings of invasions—a theme addressed by invasion genetics as a discipline—is still scarce amid well documented ecological impacts of non-native species on ecosystems of Patagonia in South America. One of the most invasive species in Patagonia’s freshwater systems and elsewhere is rainbow trout (Oncorhynchus mykiss). This...

Ocean Acidification Has Multiple Modes of Action on Bivalve Larvae

Creator:: Waldbusser, George G., Hales, Burke, Langdon, Chris J., Haley, Brian A., Schrader, Paul, Brunner, Elizabeth L., Gray, Matthew W., Miller, Cale A., Gimenez, Iria, and Hutchinson, Greg
Abstract:: Ocean acidification (OA) is altering the chemistry of the world’s oceans at rates unparalleled in the past roughly 1 million years. Understanding the impacts of this rapid change in baseline carbonate chemistry on marine organisms needs a precise, mechanistic understanding of physiological responses to carbonate chemistry. Recent experimental work has...

Integrating Temperature-Dependent Life Table Data into a Matrix Projection Model for Drosophila suzukii Population Estimation

Creator:: Wiman, Nik G., Walton, Vaughn M., Dalton, Daniel T., Anfora, Gianfranco, Burrack, Hannah J., Chiu, Joanna C., Daane, Kent M., Grassi, Alberto, Miller, Betsey, Tochen, Samantha, Wang, Xingeng, and Ioriatti, Claudio
Abstract:: Temperature-dependent fecundity and survival data was integrated into a matrix population model to describe relative Drosophila suzukii Matsumura (Diptera: Drosophilidae) population increase and age structure based on environmental conditions. This novel modification of the classic Leslie matrix population model is presented as a way to examine how insect populations interact...

Abstract:: Forest health issues are on the rise in the United States, resulting from introduction of alien pests and diseases, coupled with abiotic stresses related to climate change. Increasingly, forest scientists are finding genetic/genomic resources valuable in addressing forest health issues. For a set of ten ecologically and economically important native...

Distillation Time as Tool for Improved Antimalarial Activity and Differential Oil Composition of Cumin Seed Oil

Creator:: Zheljazkov, Valtcho D., Gawde, Archana, Cantrell, Charles L., Astatkie, Tess, and Schlegel, Vicki
Abstract:: A steam distillation extraction kinetics experiment was conducted to estimate essential oil yield, composition, antimalarial, and antioxidant capacity of cumin (Cuminum cyminum L.) seed (fruits). Furthermore, regression models were developed to predict essential oil yield and composition for a given duration of the steam distillation time (DT). Ten DT durations...

First Detection of the Larval Chalkbrood Disease Pathogen Ascosphaera apis (Ascomycota: Eurotiomycetes: Ascosphaerales) in Adult Bumble Bees

Creator:: Maxfield-Taylor, Sarah A., Mujic, Alija B., and Rao, Sujaya
Abstract:: Fungi in the genus Ascosphaera (Ascomycota: Eurotiomycetes: Ascosphaerales) cause chalkbrood disease in larvae of bees. Here, we report the first-ever detection of the fungus in adult bumble bees that were raised in captivity for studies on colony development. Wild queens of Bombus griseocollis, B. nevadensis and B. vosnesenskii were collected...

Ungulate Browsing Maintains Shrub Diversity in the Absence of Episodic Disturbance in Seasonally-Arid Conifer Forest

Creator:: Pekin, Burak K., Wisdom, Michael J., Endress, Bryan A., Naylor, Bridgett J., and Parks, Catherine G.
Abstract:: Ungulates exert a strong influence on the composition and diversity of vegetation communities. However, little is known about how ungulate browsing pressure interacts with episodic disturbances such as fire and stand thinning. We assessed shrub responses to variable browsing pressure by cattle and elk in fuels treated (mechanical removal of...

Food Webs in Relation to Variation in the Environment and Species Assemblage: A Multivariate Approach

Creator:: Schriever, Tiffany A.
Abstract:: The abiotic environment has strong influences on the growth, survival, behavior, and ecology of aquatic organisms. Biotic interactions and species life histories interact with abiotic factors to structure the food web. One measure of food-web structure is food-chain length. Several hypotheses predict a linear relationship between one environmental variable (e.g.,...

Development of Partial Ontogenic Resistance to Powdery Mildew in Hop Cones and Its Management Implications

Creator:: Twomey, Megan C., Wolfenbarger, Sierra N., Woods, Joanna L., and Gent, David H.
Abstract:: Knowledge of processes leading to crop damage is central to devising rational approaches to disease management. Multiple experiments established that infection of hop cones by Podosphaera macularis was most severe if inoculation occurred within 15 to 21 days after bloom. This period of infection was associated with the most pronounced...
