Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

AI, Robot: A Rhetorical Analysis of Jeopardy! Matches Featuring IBM’s Artificial Intelligence

Creator:: Steele, Evan T.
Abstract:: The relationship between the public and new technologies has historically been a tumultuous one, with public perceptions ranging from excited rapid adoption to standoffish pessimism. In 2011, IBM tried to use competition as a means of showcasing a new technology to the public. This thesis is a work of rhetorical...

Critically low abundance and limits to human-related mortality for the Maui's dolphin

Creator:: Hamner, Rebecca M., Wade, Paul, Oremus, Marc, Stanley, Martin, Brown, Phillip, Constantine, Rochelle, and Baker, C. Scott
Abstract:: The New Zealand endemic Maui’s dolphin Cephalorhynchus hectori maui is characterized by several life history traits thought to be important predictors of extinction risk in marine mammals, including a slow rate of reproduction, small geographic range, small group size, and coastal distribution. We continued the genetic monitoring of the remnant...

Evaluating the agreement between measurements and models of net ecosystem exchange at different times and timescales using wavelet coherence: an example using data from the North American Carbon Program Site-Level Interim Synthesis

J., Sahoo, A. K., Schaefer, K., Schwalm, C. R., Tian, H., Verbeeck, H., and Weng, E.
Abstract:: Earth system processes exhibit complex patterns across time, as do the models that seek to replicate these processes. Model output may or may not be significantly related to observations at different times and on different frequencies. Conventional model diagnostics provide an aggregate view of model–data agreement, but usually do not...

Evaluation and improvement of the Community Land Model (CLM4) in Oregon forests

Creator:: Hudiburg, T. W., Law, B. E., and Thornton, P. E.
Abstract:: Ecosystem process models are important tools for determining the interactive effects of global change and disturbance on forest carbon dynamics. Here we evaluated and improved terrestrial carbon cycling simulated by the Community Land Model (CLM4), the land model portion of the Community Earth System Model (CESM1.0.4). Our analysis was conducted...

Footprint of Positive Selection in Treponema pallidum subsp. pallidum Genome Sequences Suggests Adaptive Microevolution of the Syphilis Pathogen

Creator:: Giacani, Lorenzo, Chattopadhyay, Sujay, Centurion-Lara, Arturo, Jeffrey, BrendanM., Le, Hoavan T., Molini, Barbara J., Lukehart, Sheila A., Sokurenko, Evgeni V., and Rockey, Daniel D.
Abstract:: In the rabbit model of syphilis, infection phenotypes associated with the Nichols and Chicago strains of Treponema pallidum (T. pallidum), though similar, are not identical. Between these strains, significant differences are found in expression of, and antibody responses to some candidate virulence factors, suggesting the existence of functional genetic differences...

Performance of Linear and Nonlinear Two-Leaf Light Use Efficiency Models at Different Temporal Scales

Creator:: Wu, Xiaocui, Ju, Weimin, Zhou, Yanlian, He, Mingzhu, Law, Beverly E., Black, T. Andrew, Margolis, Hank A., Cescatti, Alessandro, Gu, Lianhong, Montagnani, Leonardo, Noormets, Asko, Griffis, Timothy J., Pilegaard, Kim, Varlagin, Andrej, Valentini, Riccardo, Blanken, Peter D., Wang, Shaoqiang, Wang, Huimin, Han, Shijie, Yan, Junhua, Li, Yingnian, Zhou, Bingbing, and Liu, Yibo
Abstract:: The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a...

Effect of age-based and environment-based cues on reproductive investment in Gambusia affinis

Creator:: Billman, Eric J. and Belk, Mark C.
Abstract:: We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:: Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.
Abstract:: Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...

Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...
