Workshop Examines Warming Of Lakes Worldwide, John D. Lenters, Simon J. Hook, Peter B. Mcintyre

School of Natural Resources: Faculty Publications

It is widely recognized that climate change is affecting terrestrial and aquatic ecosystems. Recent studies have revealed significant warming of lakes throughout the world, and this rate of warming is often larger than that of the ambient air temperature (up to 2–3 times more rapid). Although hypotheses have been proposed to explain these high rates of lake warming (e.g., ice albedo feedbacks or changes in cloud cover), the fundamental drivers remain poorly understood. Furthermore, these rapid warming rates have profound implications for lake hydrodynamics, productivity, and biotic communities. It is essential therefore that global data sets of water temperature be …

National Climate Assessment Technical Report On The Impacts Of Climate And Land Use And Land Cover Change, Thomas Loveland, Rezaul Mahmood, Toral Patel-Weynand, Krista Karstensen, Kari Beckendorf, Norman Bliss, Andrew Carlton

School of Natural Resources: Faculty Publications

This technical report responds to the recognition by the U.S. Global Change Research Program (USGCRP) and the National Climate Assessment (NCA) of the importance of understanding how land use and land cover (LULC) affects weather and climate variability and change and how that variability and change affects LULC. Current published, peer-reviewed, scientific literature and supporting data from both existing and original sources forms the basis for this report’s assessment of the current state of knowledge regarding land change and climate interactions. The synthesis presented herein documents how current and future land change may alter environment processes and in turn, how …

The Feasibility Of Switchgrass For Biofuel Production, Rob Mitchell, Kenneth P. Vogel, Daniel R. Uden

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Switchgrass research has been conducted cooperatively by the US Department of Agriculture and the University of Nebraska since the mid-1930s, with a primary focus on bioenergy since 1990 at several institutions. Progress has been made in switchgrass breeding and genetics, molecular genetics, establishment, fertility management, production economics, production energetics, harvest and storage management, ecosystem services and ethanol yield. A complete field-validated biomass production system has been developed for the Midwest and Central Plains. Even with favorable economic and sustainability results from field trials, switchgrass for bioenergy has not been adopted on a large scale. Lack of adoption is likely due …

Establishing Winter Origins Of Migrating Lesser Snow Geese Using Stable Isotopes, Viviane Hénaux, Larkin A. Powell, Mark P. Vrtiska, Keith A. Hobson

School of Natural Resources: Faculty Publications

Increases in Snow Goose (Chen caerulescens) populations and large-scale habitat changes in North America have contributed to the concentration of migratory waterfowl on fewer wetlands, reducing resource availability, and enhancing risks of disease transmission. Predicting wintering locations of migratory individuals is critical to guide wildlife population management and habitat restoration. We used stable carbon (δ¹³C), nitrogen (δ ¹⁵N), and hydrogen (δ²H) isotope ratios in muscle tissue of wintering Snow Geese to discriminate four major wintering areas, the Playa Lake Region, Texas Gulf Coast, Louisiana Gulf Coast, and Arkansas, and infer the wintering locations …

Agricultural Greenhouse Gas Emissions, Meredith Fairbanks, David Bowran, Geraldine Pasqual

Bulletins 4000 -

Agriculture contributes 15.5 per cent of Australia’s emissions (Figure 1), largely due to methane, from ruminant livestock digestion, nitrous oxide from soils and carbon dioxide from fossil fuel use (Australian National Greenhouse Accounts 2011; ABARES 2011).

This bulletin identifies current ways to reduce greenhouse gas emissions from Australian agriculture.
