Simulating dynein’s powerstroke using Brownian dynamics

Creator:: Capek, Elliott
Abstract:: Dynein is a motor protein which transports cargo along tracks inside the cell. Like related motor proteins kinesin and myosin, dynein uses cellular energy to take steps with its two foot domains. Unlike kinesin or myosin, dynein’s stepping pattern is highly varied: it can take steps between zero and 60nm...

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...

A new species of Bembidion (Ecuadion) from Ecuador (Coleoptera, Carabidae, Bembidiini), with a key to members of the georgeballi species group

Creator:: Maddison, David R. and Toledano, Luca
Abstract:: A new species of ground beetle, Bembidion ricei, is described from the Andes mountains of Ecuador east of Quito. It belongs to the georgeballi species group of subgenus Ecuadion, and is most similar to Bembidion georgeballi. A key to the species of the group is provided.

Differential surface activation of the A1 domain of von Willebrand factor

Creator:: Tronic, Elaine H., Yakovenko, Olga, Weidner, Tobias, Baio, Joe E., Penkala, Rebecca, Castner, David G., and Thomas, Wendy E.
Abstract:: The clotting protein von Willebrand factor (VWF) binds to platelet receptor glycoprotein Ibα (GPIbα) when VWF is activated by chemicals, high shear stress, or immobilization onto surfaces. Activation of VWF by surface immobilization is an important problem in the failure of cardiovascular implants, but is poorly understood. Here, the authors...

3,3'-Diindolylmethane Induces G₁ Arrest and Apoptosis in Human Acute T-Cell Lymphoblastic Leukemia Cells

Creator:: Shorey, Lyndsey E., Hagman, Amanda M., Williams, David E., Ho, Emily, Dashwood, Roderick H., and Benninghoff, Abby D.
Abstract:: Certain bioactive food components, including indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) from cruciferous vegetables, have been shown to target cellular pathways regulating carcinogenesis. Previously, our laboratory showed that dietary I3C is an effective transplacental chemopreventive agent in a dibenzo[def,p]chrysene (DBC)-dependent model of murine T-cell lymphoblastic lymphoma. The primary objective of the...

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...

Evaluating Paratransgenesis as a Potential Control Strategy for African Trypanosomiasis

Creator:: Medlock, Jan, Atkins, Katherine E., Thomas, David N., Aksoy, Serap, and Galvani, Alison P.
Abstract:: Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodalis can then be driven into...

Evolutionary Biology for the 21st Century

Creator:: Losos, Jonathan B., Arnold, Stevan J., Bejerano, Gill, Brodie, E. D. III, Hibbett, David, Hoekstra, Hopi E., Mindell, David P., Monteiro, Antonia, Moritz, Craig, Orr, H. Allen, Petrov, Dmitri A., Renner, Susanne S., Ricklefs, Robert E., Soltis, Pamela S., and Turner, Thomas L.
Abstract:: We live in an exciting time for biology. Technological advances have made data collection easier and cheaper than we could ever have imagined just 10 years ago. We can now synthesize and analyze large data sets containing genomes, transcriptomes, proteomes, and multivariate phenotypes. At the same time, society's need for...

Estimating heterotrophic respiration at large scales: challenges, approaches, and next steps

Creator:: Bond-Lamberty, Ben, Epron, Daniel, Harden, Jennifer, Harmon, Mark E., Hoffman, Forrest, Kumar, Jitendra, David McGuire, Anthony, and Vargas, Rodrigo
Abstract:: Heterotrophic respiration (HR), the aerobic and anaerobic processes mineralizing organic matter, is a key carbon flux but one impossible to measure at scales significantly larger than small experimental plots. This impedes our ability to understand carbon and nutrient cycles, benchmark models, or reliably upscale point measurements. Given that a new...

Does wildfire likelihood increase following insect outbreaks in conifer forests?

Creator:: Meigs, Garrett W., Campbell, John L., Zald, Harold S. J., Bailey, John D., Shaw, David C., and Kennedy, Robert E.
Abstract:: Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests...
