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,...

Data report : trace element, Sr isotope, and Ge/SI composition of fluid and sediments in ridge-flank low-temperature hydrothermal environments

Creator:: Hulme, Samuel M., Wheat, C. Geoffrey, Coggon, Rosalind M., and McManus, James
Abstract:: The data presented in this report demonstrate significant improvements in the ability to constrain trace element and Sr isotopic concentrations in sediments overlying ridge-flank hydrothermal systems. Improved sampling methods orchestrated by the Integrated Ocean Drilling Program (i.e., advanced piston coring and anoxic sample processing) enabled the collection of reactive pore...

Germanium in mid-ocean ridge flank hydrothermal fluids

Creator:: Wheat, C. Geoffrey and McManus, James
Abstract:: We present concentrations of germanium and silicon in sediment pore waters, basaltic formation fluids, and bulk sediment from three ridge flank hydrothermal systems (RFHS). Basaltic formation fluids from warm (>30°C) RFHS have much higher Ge concentrations and Ge:Si molar ratios than overlying sediment pore waters, requiring seawater-basalt reactions to dominate...

Sampling-based robotic information gathering algorithms

Creator:: Hollinger, Geoffrey A. and Sukhatme, Gaurav S.
Abstract:: We propose three sampling-based motion planning algorithms for generating informative mobile robot trajectories. The goal is to find a trajectory that maximizes an information quality metric (e.g. variance reduction, information gain, or mutual information) and also falls within a pre-specified budget constraint (e.g. fuel, energy, or time). Prior algorithms have...

Economic modelling of the live reef fish trade in Asia-Pacific: Developing an approach and preliminary analysis

Creator:: Petersen, Elizabeth Helen, Muldoon, Geoffrey, and Johnston, Brian
Abstract:: Reef fish traded alive for table food is a high value-to-volume fishery, with demand centred in luxury markets in Hong Kong and southern mainland China. Approximately twenty countries in the Asia-Pacific region supply these markets. A number of economic, environmental and social issues have arisen from the trade; including the...

Distributed inference-based multi-robot exploration

Creator:: Smith, Andrew J. and Hollinger, Geoffrey A.
Abstract:: This work proposes a technique for distributed multi-robot exploration that leverages novel methods of map inference. The inference technique uses observed map structure to infer unobserved map features. The team then coordinates to explore both the inferred and observed portions of the map. Individual robots select exploration poses by accounting...

Creator:: Dumbauld, Brett R., Hosack, Geoffrey R., and Bosley, Katelyn M.
Abstract:: Structured estuarine habitats, such as salt marshes, seagrass beds, and oyster reefs, are recognized as critical nurseries for juvenile fish and crustaceans. Estuarine habitat usage by fish, including juvenile Pacific salmon Oncorhynchus spp., was characterized by sampling with a modified tow net in Willapa Bay, Washington, where 20% of the...
