Viviana Ruiz-Gutierrez, Melvin B. Hooten, Evan H. Campbell Grant
2016, Methods in Ecology and Evolution (7) 900-909
Biological monitoring programmes are increasingly relying upon large volumes of citizen-science data to improve the scope and spatial coverage of information, challenging the scientific community to develop design and model-based approaches to improve inference.Recent statistical models in ecology have been developed to accommodate false-negative errors, although current...

Three ingredients for Improved global aftershock forecasts: Tectonic region, time-dependent catalog incompleteness, and inter-sequence variability
Morgan T. Page, Nicholas van der Elst, Jeanne L. Hardebeck, Karen Felzer, Andrew J. Michael
2016, Bulletin of the Seismological Society of America (106) 2290-2301
Following a large earthquake, seismic hazard can be orders of magnitude higher than the long‐term average as a result of aftershock triggering. Because of this heightened hazard, emergency managers and the public demand rapid, authoritative, and reliable aftershock forecasts. In the past, U.S. Geological Survey (USGS) aftershock forecasts following large...
Differential heating in the Indian Ocean differentially modulates precipitation in the Ganges and Brahmaputra basins
Md Shahriar Pervez, Geoffrey M. Henebry
2016, Remote Sensing (8) 1-16
Indo-Pacific sea surface temperature dynamics play a prominent role in Asian summer monsoon variability. Two interactive climate modes of the Indo-Pacific—the El Niño/Southern Oscillation (ENSO) and the Indian Ocean dipole mode—modulate the amount of precipitation over India, in addition to precipitation over Africa, Indonesia, and Australia. However, this modulation is...
Large along-strike variations in the onset of Subandean exhumation: Implications for Central Andean orogenic growth
Richard O. Lease, T.A. Ehlers, E. Enkelmann
2016, Earth and Planetary Science Letters (451) 62-76
Plate tectonics drives mountain building in general, but the space-time pattern and style of deformation is influenced by how climate, geodynamics, and basement structure modify the orogenic wedge. Growth of the Subandean thrust belt, which lies at the boundary between the arid, high-elevation Central Andean Plateau and its humid, low-elevation...
Recurrent hybridization and recent origin obscure phylogenetic relationships within the ‘white-headed’ gull (Larus sp.) complex
Sarah A. Sonsthagen, Robert E. Wilson, Terry Chesser, Jean-Marc Pons, Pierre-Andre Crochet, Amy Driscoll, Carla Dove
2016, Molecular Phylogenetics and Evolution (103) 41-54
Species complexes that have undergone recent radiations are often characterized by extensive allele sharing due to recent ancestry and (or) introgressive hybridization. This can result in discordant evolutionary histories of genes and heterogeneous genomes, making delineating species limits difficult. Here we examine the phylogenetic relationships among a complex group of...

Guy M. Foster, Jennifer L. Graham, Thomas J. Williams, Lindsey R. King
2016, Scientific Investigations Report 2016-5147
Nutrients, particularly nitrogen and phosphorus, are a leading cause of water-quality impairment in Kansas and the Nation. Indian Creek is one of the most urban drainage basins in Johnson County, Kansas, and environmental and biological conditions are affected by contaminants from point and other urban sources. The Johnson County Douglas...
Is consolidation drainage an indirect mechanism for increased abundance of cattail in northern prairie wetlands?
Mark T. Wiltermuth, Michael J. Anteau
2016, Wetlands Ecology and Management (24) 533-544
In the Prairie Pothole Region of North America, disturbances to wetlands that disrupt water-level fluctuations in response to wet–dry climatic conditions have the potential to alter natural vegetative communities in favor of species that proliferate in stable environments, such as cattail (Typha spp.). We evaluated the effect of water-level dynamics...

Aubrey R. Bunch
2016, Proceedings of the Indiana Academy of Science (125) 137-150
Transport of excess nutrients and total suspended solids (TSS) such as sediment by freshwater systems has led to degradation of aquatic ecosystems around the world. Nutrient and TSS loads from Midwestern states to the Mississippi River are a major contributor to the Gulf of Mexico Hypoxic Zone, an area of...

2016, Marine Geology (381) 42-53
Behavior of coastal systems on time scales ranging from single storm events to years and decades is controlled by both small-scale sediment transport processes and large-scale geologic, oceanographic, and morphologic processes. Improved understanding of coastal behavior at multiple time scales is required for refining models that predict potential erosion hazards...

Erin E. Silvestri, David Feldhake, Dale Griffin, John T. Lisle, Tonya L. Nichols, Sanjiv Shah, A Pemberton, Frank W Schaefer III
2016, Journal of Microbiological Methods (130) 6-13
Following a release of Bacillus anthracis spores into the environment, there is a potential for lasting environmental contamination in soils. There is a need for detection protocols for B. anthracis in environmental matrices. However, identification of B. anthracis within a soil is a difficult task. Processing soil samples helps to...

Trenton W. J. Garner, Benedikt R. Schmidt, An Martel, Frank Pasmans, Erin L. Muths, Andrew A. Cunningham, Che Weldon, Matthew C. Fisher, Jaime Bosch
2016, Philosophical Transactions of the Royal Society B: Biological Sciences (371)
Amphibians across the planet face the threat of population decline and extirpation caused by the disease chytridiomycosis. Despite consensus that the fungal pathogens responsible for the disease are conservation issues, strategies to mitigate their impacts in the natural world are, at best, nascent. Reducing risk associated with the movement of...
