David R Smith, Ph.D.
Dave is a Research Statistician (Biology) at the Eastern Ecological Science Center in Kearneysville, WV.
Dave Smith graduated from Colorado State (MS in Fish and Wildlife Biology) and University of Georgia (MS in Statistics and PhD in Forest Resources). Currently, he is a biological statistician at the USGS Leetown Science Center where he focuses on applied quantitative ecology in support of natural resource management and environmental decision making.
His research activities mostly focus on the following topics:
- Adaptive sampling of rare and clustered populations
- Conservation and science of horseshoe crabs in North America and Asia
- Conservation of freshwater mussels
- Application of structured decision making and adaptive management to natural resource management

Continuous monitoring of dissolved oxygen and total dissolved gas pressure based on head-space partial pressures Continuous monitoring of dissolved oxygen and total dissolved gas pressure based on head-space partial pressures
We describe an instrument prototype that measures total dissolved gas pressure (TGP) and dissolved oxygen (DO) without need for standard wetted probe membranes or gas permeable tubing. Measurements were based instead on gas-phase partial pressures that develop within the head-space of a pressure vessel, and on Henry's Law. Performance trials established that differences between standard

A revised annotated checklist of the Chironomidae (Insecta: Diptera) of the southeastern United States A revised annotated checklist of the Chironomidae (Insecta: Diptera) of the southeastern United States
A revised annotated checklist for the chironomid midges (Diptera: Chironomidae) of the southeastern United States is presented that includes the states of Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee. Much of the information concerns occurrence and habitat preference records based upon the authors' data, as well as published and unpublished data. Some...

Factors affecting visibility rate of aerial waterfowl surveys in the Mississippi alluvial valley Factors affecting visibility rate of aerial waterfowl surveys in the Mississippi alluvial valley
Because visibility bias can confound attempts to detect changes in abundance, we evaluated factors that affect visibility rate in aerial surveys of wintering waterfowl. We placed waterfowl decoys in 32 2- x 0.25-km strip transects in the Mississippi Alluvial Valley (MAV) during February 1990 and 1991 and observed the decoys under different experimental conditions. Visibility rate was...

Point count length and detection of forest neotropical migrant birds Point count length and detection of forest neotropical migrant birds
Comparisons of bird abundances among years or among habitats assume that the rates at which birds are detected and counted are constant within species. We use point count data collected in forests of the Mid-Atlantic states to estimate detection probabilities for Neotropical migrant bird species as a function of count length. For some species, significant differences existed among years...
