Late quaternary changes in lakes, vegetation, and climate in the Bonneville Basin reconstructed from sediment cores from Great Salt Lake: Chapter 11
Robert S. Thompson, Charles G. Oviatt, Jeffrey S. Honke, John McGeehin
2016, Book chapter, Developments in earth surface processes: Lake Bonneville — A scientific update
Sediment cores from Great Salt Lake (GSL) provide the basis for reconstructing changes in lakes, vegetation, and climate for the last ~ 40 cal ka. Initially, the coring site was covered by a shallow saline lake and surrounded by Artemisia steppe or steppe-tundra under a cold and dry climate. As Lake Bonneville...
Geomorphic evolution of the San Luis Basin and Rio Grande in southern Colorado and northern New Mexico
Chester A. Ruleman, Michael Machette, Ren A. Thompson, Dan M Miggins, Brent M Goehring, James B. Paces
2016, GSA Field Guides (44) 291-333
The San Luis Basin encompasses the largest structural and hydrologic basin of the Rio Grande rift. On this field trip, we will examine the timing of transition of the San Luis Basin from hydrologically closed, aggrading subbasins to a continuous fluvial system that eroded the basin, formed the Rio Grande...
Fidelity and persistence of Ring-billed (Larus delawarensis) and Herring (Larus argentatus) gulls to wintering sites
Daniel E. Clark, Kiana K. G. Koenen, Jillian J. Whitney, Kenneth G. MacKenzie, Stephen DeStefano
2016, Waterbirds (39) 220-234
While the breeding ecology of gulls (Laridae) has been well studied, their movements and spatial organization during the non-breeding season is poorly understood. The seasonal movements, winter-site fidelity, and site persistence of Ring-billed (Larus delawarensis) and Herring (L. argentatus) gulls to wintering areas were studied from 2008–2012. Satellite transmitters were...

2016, Book chapter, Golden-winged Warbler ecology, conservation, and habitat management (Studies in Avian Biology, volume 49)
Avian habitat selection occurs at multiple spatial scales to incorporate life history requirements. Breeding habitat of Golden-winged Warblers (Vermivora chrysoptera) is characterized by largely forested landscapes containing natural or anthropogenic disturbance elements that maintain forest patches in early stages of succession. Breeding habitat occurs in a variety of settings, including...

Lethal thermal maxima for age-0 pallid and shovelnose sturgeon: Implications for shallow water habitat restoration
David Deslauriers, Laura B. Heironimus, Steven R. Chipps
2016, River Research and Applications (32) 1872-1878
We evaluated temperature tolerance in age-0 pallid and shovelnose sturgeon (Scaphirhynchus albus and Scaphirhynchus platorynchus), two species that occur sympatrically in the Missouri and Mississippi Rivers. Fish (0.04–18 g) were acclimated to water temperatures of 13, 18 or 24 °C to quantify temperatures associated with lethal thermal maxima (LTM). The results show...

Feeding ecology of non-native Siberian prawns, Palaemon modestus (Heller, 1862) (Decapoda, Palaemonidae), in the lower Snake River, Washington, U.S.A.
Kenneth F. Tiffan, William Hurst
2016, Crustaceana (89) 721-736
We used both stomach content and stable isotope analyses to describe the feeding ecology of Siberian prawns Palaemon modestus (Heller, 1862), a non-native caridean shrimp that is a relatively recent invader of the lower Snake River. Based on identifiable prey in stomachs, the opossum shrimp Neomysis mercedis Holmes, 1896 comprised...

We characterize...
Acoustic doppler velocimeter backscatter for quantification of suspended sediment concentration in South San Francisco Bay
Mehmet Ozturk, Paul A. Work
2016, Conference Paper, Coastal engineering proceedings
A data set was acquired on a shallow mudflat in south San Francisco Bay that featured simultaneous, co-located optical and acoustic sensors for subsequent estimation of suspended sediment concentrations (SSC). The optical turbidity sensor output was converted to SSC via an empirical relation derived at a nearby site using bottle...
Natural soil reservoirs for human pathogenic and fecal indicator bacteria
Maria L Boschiroli, Joseph Falkinham, Sabine Favre-Bonte, Sylvie Nazaret, Pascal Piveteau, Michael J. Sadowsky, Muruleedhara Byappanahalli, Pascal Delaquis, Alain Hartmann
2016, Book chapter, Manual of environmental microbiology
Soils receive inputs of human pathogenic and indicator bacteria through land application of animal manures or sewage sludge, and inputs by wildlife. Soil is an extremely heterogeneous substrate and contains meso- and macrofauna that may be reservoirs for bacteria of human health concern. The ability to detect and quantify bacteria...
