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,...

Prediction of understory vegetation cover with airborne lidar in an interior ponderosa pine forest

Creator:: Wing, Brian M., Ritchie, Martin W., Boston, Kevin, Cohen, Warren B., Gitelman, Alix, and Olsen, Michael J.
Abstract:: Forest understory communities are important components in forest ecosystems providing wildlife habitat and influencing nutrient cycling, fuel loadings, fire behavior and tree species composition over time. One of the most widely utilized understory component metrics is understory vegetation cover, often used as a measure of vegetation abundance. To date, understory...

Evidence of a dissolution effect on benthic foraminiferal shell chemistry: δ¹³C, Cd/Ca, Ba/Ca, and Sr/Ca results from the Ontong Java Plateau

Creator:: McCorkle, Daniel C., Martin, Pamela A., Lea, David W., and Klinkhammer, Gary P.
Abstract:: Core-top benthic foraminifera (Cibicidoides wuellerstorfi) from a depth transect of Soutar box cores from the Ontong-Java Plateau (1.6 – 4.4 km) were analyzed for cadmium, barium, and strontium (Cd/Ca, Ba/Ca, and Sr/Ca) and for their stable isotopic composition (δ¹³C and δ¹⁸O). We also measure bottom water δ¹³C, Cd, and Ba...

Using the ⁸⁷Sr/⁸⁶Sr of modern and paleoseep carbonates from northern Cascadia to link modern fluid flow to the past

Creator:: Joseph, C., Torres, M. E., Martin, R. A., Haley, B. A., Pohlman, J. W., Riedel, M., and Rose, K.
Abstract:: Most authigenic carbonates previously recovered from the Cascadia slope have Sr-⁸⁷/Sr-⁸⁶ signatures that reflect shallow precipitation in equilibrium with coeval seawater. There is also evidence for carbonate formation supported by fluids that have been modified by reactions with the incoming Juan de Fuca plate (Sr-⁸⁷/⁸⁶(Sr) = 0.7071; Teichert et al.,...

2014 Pest management guide for wine grapes in Oregon

Creator:: Skinkis, Patricia A., Pscheidt, Jay W., Peachey, Ed, Dreves, Amy J., Walton, Vaughn M., Sanchez, Dana Michelle, Zasada, Inga, Martin, Robert, and Oregon State University. Extension Service
Abstract:: This publication reviews the growth stages of grapes. For each growth stage (or group of growth stages), the document lists the more effective pesticides used to control insects, weeds, and disease, their rates, and application timing for Oregon grape growers. It also covers the effectiveness of various fungicides for control...

Spatially explicit capture–recapture methods to estimate minke whale density from data collected at bottom-mounted hydrophones

Creator:: Marques, Tiago A., Thomas, Len, Martin, Stephen W., Mellinger, David K., Jarvis, Susan, Morrissey, Ronald P., Ciminello, Carroll-Anne, and DiMarzio, Nancy
Abstract:: Estimation of cetacean abundance or density using visual methods can be cost-ineffective under many scenarios. Methods based on acoustic data have recently been proposed as an alternative, and could potentially be more effective for visually elusive species that produce loud sounds. Motivated by a dataset of minke whale (Balaenoptera acutorostrata)...

In situ enrichment of ocean crust microbes on igneous minerals and glasses using an osmotic flow‐through device

Creator:: Smith, Amy, Popa, Radu, Fisk, Martin, Nielsen, Mark, Wheat, C. Geoffrey, Jannasch, Hans W., Fisher, Andrew T., Becker, Keir, Sievert, Stefan M., and Flores, Gilberto
Abstract:: The Integrated Ocean Drilling Program (IODP) Hole 1301A on the eastern flank of Juan de Fuca Ridge was used in the first long-term deployment of microbial enrichment flow cells using osmotically driven pumps in a subseafloor borehole. Three novel osmotically driven colonization systems with unidirectional flow were deployed in the...
