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...

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...

Assessing the design and power of capture-recapture studies to estimate demographic parameters for the Endangered Oceania humpback whale population

Creator:: Carroll, E. L., Brooks, L., Baker, C. S., Burns, D., Garrigue, C., Hauser, N., Jackson, J. A., Poole, M. M., and Fewster, R. M.
Abstract:: Capture-recapture studies offer a powerful tool to assess abundance, survival and population rate of change (λ). A previous capture-recapture study, based on DNA profiles, estimated that the IUCN-listed Endangered Oceania population of humpback whales had a superpopulation size of 4329 whales (95% confidence limits, CL: 3345, 5315) and λ =...

Factors Controlling Soil Microbial Biomass and Bacterial Diversity and Community Composition in a Cold Desert Ecosystem: Role of Geographic Scale

Creator:: Van Horn, David J., Van Horn, M. Lee, Barrett, John E., Gooseff, Michael N., Altrichter, Adam E., Geyer, Kevin M., Zeglin, Lydia H., and Takacs-Vesbach, Cristina D.
Abstract:: Understanding controls over the distribution of soil bacteria is a fundamental Understanding controls over the distribution of soil bacteria is a fundamental step toward describing soil ecosystems, understanding their functional capabilities, and predicting their responses to environmental change. This study investigated the controls on the biomass, species richness, and community...

Convergent diversity and trait composition in temporary streams and ponds

Creator:: Schriever, Tiffany A. and Lytle, David A.
Abstract:: Hydrology is the main environmental filter in aquatic ecosystems and may result in shared tolerances and functional traits among species in disparate ecosystems. We analyzed the associations between taxonomic and functional facets of diversity within aquatic ecosystems (ponds vs. streams) across a hydroperiod gradient (1–365 d) to untangle the hydrologic...

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.

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...

Extensive Transcriptome Changes During Natural Onset and Release of Vegetative Bud Dormancy in Populus

Creator:: Howe, Glenn T., Horvath, David P., Dharmawardhana, Palitha, Priest, Henry D., Mockler, Todd C., and Strauss, Steven H.
Abstract:: To survive winter, many perennial plants become endodormant, a state of suspended growth maintained even in favorable growing environments. To understand vegetative bud endodormancy, we collected paradormant, endodormant, and ecodormant axillary buds from Populus trees growing under natural conditions. Of 44,441 Populus gene models analyzed using NimbleGen microarrays, we found...
