Christopher A. Barnes, David P. Roy, Thomas R. Loveland
2013, Journal of Land Change Science (8) 369-382
Satellite-derived contemporary land-cover land-use (LCLU) and albedo data and modeled future LCLU are used to study the impact of LCLU change from 2000 to 2050 on surface albedo and radiative forcing for 19 ecoregions in the eastern United States. The modeled 2000–2050 LCLU changes indicate a future decrease in both...
A framework for understanding semi-permeable barrier effects on migratory ungulates
Hall Sawyer, Matthew J. Kauffman, Arthur D. Middleton, Thomas A. Morrison, Ryan M. Nielson, Teal B. Wyckoff
2013, Journal of Applied Ecology (50) 68-78
1. Impermeable barriers to migration can greatly constrain the set of possible routes and ranges used by migrating animals. For ungulates, however, many forms of development are semi-permeable, and making informed management decisions about their potential impacts to the persistence of migration routes is difficult because our knowledge of how...

Guido Grosse, Benjamin M. Jones, Christopher D. Arp
John F. Shroder, editor(s)
2013, Book chapter, Treatise on Geomorphology
Thermokarst lakes and drained lake basins are widespread in Arctic and sub-Arctic permafrost lowlands with ice-rich sediments. Thermokarst lake formation is a dominant mode of permafrost degradation and is linked to surface disturbance, subsequent melting of ground ice, surface subsidence, water impoundment, and positive feedbacks between lake growth and permafrost...
An alternative process model of preferential contaminant travel times in the unsaturated zone: Application to Rainier Mesa and Shoshone Mountain, Nevada
Brian A. Ebel, John R. Nimmo
2013, Environmental Modeling & Assessment (18) 345-363
Simulating contaminant transport in unsaturated zones with sparse hydraulic property information is a difficult, yet common, problem. When contaminant transport may occur via preferential flow, simple modeling approaches can provide predictions of interest, such as the first arrival of contaminant, with minimal site characterization. The conceptual model for unsaturated zone...
Optimal temperature for malaria transmission is dramatically lower than previously predicted
Erin A. Mordecai, Krijn P. Paaijmans, Leah R. Johnson, Christian Balzer, Tal Ben-Horin, Emily de Moor, Amy McNally, Samraat Pawar, Sadie J. Ryan, Thomas C. Smith, Kevin D. Lafferty
2013, Ecology Letters (16) 22-30
The ecology of mosquito vectors and malaria parasites affect the incidence, seasonal transmission and geographical range of malaria. Most malaria models to date assume constant or linear responses of mosquito and parasite life-history traits to temperature, predicting optimal transmission at 31 °C. These models are at odds with field observations...

2013, Climatic Change (116) 71-95
Meteorology is the driving force for lake internal heating, cooling, mixing, and circulation. Thus continued global warming will affect the lake thermal properties, water level, internal nutrient loading, nutrient cycling, food-web characteristics, fish-habitat, aquatic ecosystem, and other important features of lake limnology. Using a 1-D numerical model - the Lake...
Environmental factors regulating the recruitment of walleye Sander vitreus and white bass Morone chrysops in irrigation reservoirs
Jason A. DeBoer, Kevin L. Pope, Keith D. Koupal
2013, Ecology of Freshwater Fish (22) 43-54
Understanding the environmental factors that regulate fish recruitment is essential for effective management of fisheries. Generally, first-year survival, and therefore recruitment, is inherently less consistent in systems with high intra- and interannual variability. Irrigation reservoirs display sporadic patterns of annual drawdown, which can pose a substantial challenge to recruitment of...

Jayne Belnap, Bradford P. Wilcox, Matthew V. Van Scoyoc, Susan L. Phillips
2013, Ecohydrology (6) 474-482
Biological soil crusts are a key component of many dryland ecosystems. Following disturbance, biological soil crusts will recover in stages. Recently, a simple classification of these stages has been developed, largely on the basis of external features of the crusts, which reflects their level of development (LOD). The classification system...
