Describes project to identify sources of fecal coliform bacteria by ribotyping to develop the use of Maximum Daily Load (TMDL) values for contaminated stream segments in Virginia.
Report on the use of regression equations from measurements made by water quality monitors and analytical results of manually collected samples estimating nutrient, bacteria, and other constituent concentrations to study streams in Kansas.
Chapter of Field Manual of Wildlife Diseases on algal toxins, red tide toxins, phycotoxins, dinoflagellates, cyanobacterium, and bird mortality due to algal toxicosis.
Explains biological soil crusts, organism-produced soil formations commonly found in semiarid and arid environments, with special reference to their biological composition, physical characteristics, and ecological significance.
Fact sheet on the need to protect biological soil crusts in the desert. These crusts are most of the soil surface in deserts not covered by green plants and are inhabited by cyanobacterium (blue-green algae) and other organisms useful to the ecosystem.
Manual listing field procedures for bird specimen collecting, bacterial, fungal, parasitic, and viral diseases, biotoxins, chemical toxins, common and scientific names of birds, and glossary. Manual can be downloaded or viewed in PDF format.
Description of a project to develop watershed models that can be used to track sources of fecal coliform bacteria by assigning Total Maximum Daily Loads (TMDL) to three stream segments in Virginia.
