Hydrologic-Carbon Cycle Linkages In A Subalpine Catchment, Diego Andrés Riveros-Iregui Sep 2008

Hydrologic-Carbon Cycle Linkages In A Subalpine Catchment, Diego Andrés Riveros-Iregui

School of Natural Resources: Faculty Publications

The feedbacks between the water and the carbon cycles are of critical importance to global carbon balances. Forests and forest soils in northern latitudes are important carbon pools because of their potential as sinks for atmospheric carbon. However there are significant unknowns related to the effects of hydrologic variability, mountainous terrain, and landscape heterogeneity in controlling soil carbon dioxide (CO2) efflux. Mountainous terrain imposes large spatial heterogeneity in the biophysical controls of soil CO2 production and efflux, including soil temperature, soil water content, vegetation, substrate, and soil physical properties. Strong spatial and temporal variability in biophysical controls …

Phylogeographical Structure And Evolutionary History Of Two Buggy Creek Virus Lineages In The Western Great Plains Of North America, Abinash Padhi, Amy T. Moore, Mary Bomberger Brown, Jerome E. Foster, Martin Pfeffer, Kathryn P. Gaines, Valerie A. O'Brien, Stephanie A. Strickler, Allison E. Johnson, Charles R. Brown

School of Natural Resources: Faculty Publications

Buggy Creek virus (BCRV) is an unusual arbovirus within the western equine encephalitis complex of alphaviruses. Associated with cimicid swallow bugs (Oeciacus vicarius) as its vector and the cliff swallow (Petrochelidon pyrrhonota) and house sparrow (Passer domesticus) as its amplifying hosts, this virus is found primarily in the western Great Plains of North America at spatially discrete swallow nesting colonies. For 342 isolates collected in Oklahoma, Nebraska, Colorado, and North Dakota, from 1974 to 2007, we sequenced a 2076 bp region of the 26S subgenomic RNA structural glycoprotein coding region, and analyzed phylogenetic relationships, …


Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert J. Brecha Sep 2008

Emissions Scenarios In The Face Of Fossil-Fuel Peaking, Robert J. Brecha

Physics Faculty Publications

Emissions scenarios used by the Intergovernmental Panel on Climate Change (IPCC) are based on detailed energy system models in which demographics, technology and economics are used to generate projections of future world energy consumption, and therefore, of greenhouse gas emissions. We propose in this paper that it is useful to look at a qualitative model of the energy system, backed by data from short- and medium-term trends, to gain a sense of carbon emission bounds. Here we look at what may be considered a lower bound for 21st century emissions given two assumptions: first, that extractable fossil-fuel resources follow the …


Winterkill And Biomass Of The Painted Turtle In A South Dakota Wetland, Steven G. Platt, Zannita Fast Horse, Warren Cross, Sylvio Mannel, Thomas R. Rainwater Sep 2008

Winterkill And Biomass Of The Painted Turtle In A South Dakota Wetland, Steven G. Platt, Zannita Fast Horse, Warren Cross, Sylvio Mannel, Thomas R. Rainwater

The Prairie Naturalist

Winterkill occurs when drought conditions expose hibernating turtles to desiccation and lethaly cold temperatures. Winterkill is thought to represent a major source of mortality in northern populations of the painted turtle (Chrysemys picta), but few field observations are available. We herein reported on catastrophic winterkill among western painted turtle (C. pieta bellii) at Limestone Butte Lake (LBL) in western South Dakota during the winter of 2003-2004. Additionally, we used the carcasses of winterkilled turtles (n = 86) to estimate the standing crop biomass of the painted turtle at LBL (0.6 kg/ha). This was the only estimate …

Sspnd –Support System For Phosphorus And Nitrogen Decisions – Modeling Of Management Practices Can Guide The Way Ahead, Simon Neville, David Weaver, Rebecca Ovens, Nardia Keipert, Robert Summers, Martin Clarke

Conference papers and presentations

Algal blooms in rivers and estuarine waters in south west Western Australia are a symptomatic response to excess nutrient input. Whilst a range of Best Management Practices (BMPs) are available to reduce the causes of phosphorus (P) and nitrogen (N) pollution, most investment has been directed towards symptoms. In order to treat nutrient pollution causes effectively, possible nutrient reductions and the likely adoption costs of a range of BMPs require evaluation. Catchment-scale evaluation of implementation scenarios offers insights not possible through long term on-ground implementation and performance monitoring, and assists community groups and government to respond to pollution issues through …

Paddlefish Egg Deposition In The Lower Yellowstone River, Montana And North Dakota, Shannon E. Miller, Dennis L. Scarnecchia, Steven R. Fain Aug 2008

Paddlefish Egg Deposition In The Lower Yellowstone River, Montana And North Dakota, Shannon E. Miller, Dennis L. Scarnecchia, Steven R. Fain

The Prairie Naturalist

We used passive egg collectors during May, June, and July of2003 and 2004 in the lower 50 river kiiometers (rkm) of the Yellowstone River, eastern Montana and western North Dakota, to detect egg deposition by spawning paddle fish (Polyodon spathula). Sampling yielded 292 eggs (46 in 2003 and 246 in 2004). All egg collections in 2003 occurred on the descending limb of the spring hydrograph but 99% of egg collections in 2004 occurred before the spring hydrograph began to descend. Catch-per-unit-effort (CPUE) in 2004 was about four times that of 2003. A combination of river conditions, in addition …


Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea Aug 2008

Geology And Hydrology Of Karst In West-Central And North-Central Florida, Lee J. Florea

Earth, Environmental, and Atmospheric Sciences Faculty Publications

The state of Florida is blessed with the highest density of large springs in North America and hundreds of smaller springs where the water from limestone aquifers returns to the surface (Scott et al., 2004). Spectacular underwater caves supply water to these springs. Lesser known are the equally fantastic air-filled caves of Florida and South Georgia (Florea, 2006; Lane, 1986). This paper features these underwater and airfilled caves, explores the impact of changes in sea level on karst in this near-coastal environment, and establishes several geologic and hydrologic characteristics that distinguish karst in the limestones of the southeast from karst …

Grassland Songbird Survival And Recruitment In Agricultural Landscapes: Implications For Source-Sink Demography, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley Jul 2008

Grassland Songbird Survival And Recruitment In Agricultural Landscapes: Implications For Source-Sink Demography, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

Population growth and decline are particularly sensitive to changes in three key life-history parameters: annual productivity, juvenile survival, and adult survival. However, for many species these parameters remain unknown. For example, although grassland songbirds are imperiled throughout North America, for this guild, only a small number of studies have assessed these parameters. From 2002 to 2006, in the agricultural landscape of the Champlain Valley of Vermont and New York, USA, we studied Savannah Sparrow (Passerculus sandwichensis) and Bobolink (Dolichonyx oryzivorus) demography on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- …

Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth Jul 2008

Alien Invaders! Pre-Visit Lesson: Introduced And Invasive Species (Grade 6), Discover Mojave: Forever Earth

Curriculum materials (FE)

In the “Alien Invaders!” program, students use the Forever Earth vessel to investigate how quagga mussels might affect Lake Mead. Students collect water quality data such as clarity, pH, and temperature to determine whether current habitat conditions would allow quagga mussels to survive and thrive. Students learn about the consequences the quagga mussels could have on the lake and its living and non-living resources. Using the knowledge they’ve gained, students create their own management plans to prevent the spread of quagga mussels to other waterways.

This activity involves students in the concepts of introduced and invasive species


The Economic Impact Of The Kentucky Green River Conservation Reserve Enhancement Program (Crep), Lorie B. Owen Jul 2008

The Economic Impact Of The Kentucky Green River Conservation Reserve Enhancement Program (Crep), Lorie B. Owen

Mahurin Honors College Capstone Experience/Thesis Projects

This study examines the impact of the Conservation Reserve Enhancement Program (CREP) on fourteen Kentucky counties. The CREP program is an advancement of the Conservation Reserve Program (CRP) which began nationally in 1985. The primary intention of both programs is to improve water quality and reduce soil erosion. Thus, in order to stimulate conservation efforts, farmers are given an opportunity to remove land from current production and still reap financial benefits. When CREP was introduced to Kentucky in 2002, the program provided far more lucrative incentives than the parent program. In 2007 CREP underwent an amendment process that broadened the …
