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.

Catching the Right Wave: Evaluating Wave Energy Resources and Potential Compatibility with Existing Marine and Coastal Uses

Creator:: Kim, Choong-Ki, Toft, Jodie E., Papenfus, Michael, Verutes, Gregory, Guerry, Anne D., Ruckelshaus, Marry H., Arkema, Katie K., Guannel, Gregory, Wood, Spencer A., Bernhardt, Joanna R., Tallis, Heather, Plummer, Mark L., Halpern, Benjamin S., Pinsky, Malin L., Beck, Michael W., Chan, Francis, Chan, Kai M. A., Levin, Phil S., and Polasky, Stephen
Abstract:: Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows the...

Circadian Regulation of Glutathione Levels and Biosynthesis in Drosophila melanogaster

Creator:: Beaver, Laura M., Klichko, Vladimir I., Chow, Eileen S., Kotwica-Rolinska, Joanna, Williamson, Marisa, Orr, William C., Radyuk, Svetlana N., and Giebultowicz, Jadwiga M.
Abstract:: Circadian clocks generate daily rhythms in neuronal, physiological, and metabolic functions. Previous studies in mammals reported daily fluctuations in levels of the major endogenous antioxidant, glutathione (GSH), but the molecular mechanisms that govern such fluctuations remained unknown. To address this question, we used the model species Drosophila, which has a...

Effects of Cu/Zn Superoxide Dismutase (sod1) Genotype and Genetic Background on Growth, Reproduction and Defense in Biomphalaria glabrata

Creator:: Bonner, Kaitlin M., Bayne, Christopher J., Larson, Maureen K., and Blouin, Michael S.
Abstract:: Resistance of the snail Biomphalaria glabrata to the trematode Schistosoma mansoni is correlated with allelic variation at copper-zinc superoxide dismutase (sod1). We tested whether there is a fitness cost associated with carrying the most resistant allele in three outbred laboratory populations of snails. These three populations were derived from the...

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...

In Vivo Quantification Reveals Extensive Natural Variation in Mitochondrial Form and Function in Caenorhabditis briggsae

Creator:: Hicks, Kiley A., Howe, Dana K., Leung, Aubrey, Denver, Dee R., and Estes, Suzanne
Abstract:: In We have analyzed natural variation in mitochondrial form and function among a set of Caenorhabditis briggsae isolates known to harbor mitochondrial DNA structural variation in the form of a heteroplasmic nad5 gene deletion (nad5 Delta) that correlates negatively with organismal fitness. We performed in vivo quantification of 24 mitochondrial...

Non-Invasive Sampling of Schistosomes from Humans Requires Correcting for Family Structure

Creator:: Steinauer, Michelle L., Christie, Mark R., Blouin, Michael S., Agola, Lelo E., Mwangi, Ibrahim N., Maina, Geoffrey M., Mutuku, Martin W., Kinuthia, Joseph M., Mkoji, Gerald M., and Loker, Eric S.
Abstract:: For ethical and logistical reasons, population-genetic studies of parasites often rely on the non-invasive sampling of offspring shed from their definitive hosts. However, if the sampled offspring are naturally derived from a small number of parents, then the strong family structure can result in biased population-level estimates of genetic parameters,...

Selfish Little Circles: Transmission Bias and Evolution of Large Deletion-Bearing Mitochondrial DNA in Caenorhabditis briggsae Nematodes

Creator:: Clark, Katie A., Howe, Dana K., Gafner, Kristin, Kusuma, Danika, Ping, Sita, Estes, Suzanne, and Denver, Dee R.
Abstract:: Selfish DNA poses a significant challenge to genome stability and organismal fitness in diverse eukaryotic lineages. Although selfish mitochondrial DNA (mtDNA) has known associations with cytoplasmic male sterility in numerous gynodioecious plant species and is manifested as petite mutants in experimental yeast lab populations, examples of selfish mtDNA in animals...

Tapeworm Eggs in a 270 Million-Year-Old Shark Coprolite

Creator:: Dentzien-Dias, Paula C., Poinar, George, Jr., de Figueiredo, Ana Emilia Q., Pacheco, Ana Carolina L., Horn, Bruno L. D., and Schultz, Cesar L.
Abstract:: Remains of parasites in vertebrates are rare from the Mesozoic and Paleozoic. Once most parasites that live in - or pass through - the gastrointestinal tract of vertebrates, fossil feces (coprolites) or even intestinal contents (enterolites) can eventually preserve their remains. Here we announce the discovery of a spiral shark...
