2008, Molecular Immunology (45) 1646-1657
Major histocompatibility complex (MHC) molecules are important mediators of cell-mediated immunity in vertebrates. MHC class IA molecules are important for host anti-viral immunity as they present intracellular antigens and regulate natural killer cell (NK) activity. MHC class Ib molecules on the other hand are less understood and have demonstrated diverse...

Spatially explicit decision support systems are assuming an increasing role in natural resource and conservation management. In order for these systems to be successful, however, they must address real-world management problems with input from both the scientific and management communities. The National Training Center at Fort Irwin, California, has expanded...
Chemical Results of Laboratory Dry/Rewet Experiments Conducted on Wetland Soils from Two Sites in the Everglades, Florida
William H. Orem
2008, Open-File Report 2008-1090
Drought and fire are natural environmental factors that have historically impacted and shaped the Everglades ecosystem. For example, drought and fire help to maintain the existing ecosystem biotic assemblage by periodically eradicating invading flora not adapted to living with this normal aspect of Everglades' ecology. Flora native to the Everglades...

A New Method for Mapping Population Distribution
Rachel Sleeter
2008, Fact Sheet 2008-3010
Human population counts are collected and commonly displayed uniformly across areas, such as U.S. Census Bureau block-groups and tracts. The limitation inherent in this type of representation is the assumption that people are evenly distributed across each areal unit, when in actuality many areas such as parks, open spaces, and...

Joseph M. Richards, Douglas N. Mugel
2008, Scientific Investigations Map 3003
INTRODUCTION A study of the water resources of the Springfield, Missouri, area in the 1970s determined that a cone of depression, formed by ground-water pumping, had developed in the Ozark aquifer beneath the city (Emmett and others, 1978). Continued ground-water usage in the 1970s and 1980s caused concern that ground-water resources...

Mineral aerosols from dust are an important influence on climate and on marine and terrestrial biogeochemical cycles. These aerosols are generated from wind erosion of surface soils. The amount of dust emission can therefore be affected by human activities that alter surface sediments. However, changes in regional- and global-scale dust...

Stephen Riley, K.R. Munkittrick, Allison N. Evans, Charles C. Krueger
2008, Aquatic Ecosystem Health & Management (11) 321-334
Disease may be an important factor affecting wild fish population dynamics in the Great Lakes, but a lack of information on the ecology of fish disease currently precludes the prediction of risks to fish populations. Here we propose a conceptual framework for conducting ecologically-oriented fish health research that addresses the...
