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

Multi-species attributes as the condition for adaptive sampling of rare species using two-stage sequential sampling with an auxiliary variable Multi-species attributes as the condition for adaptive sampling of rare species using two-stage sequential sampling with an auxiliary variable
Assessing populations of rare species is challenging because of the large effort required to locate patches of occupied habitat and achieve precise estimates of density and abundance. The presence of a rare species has been shown to be correlated with presence or abundance of more common species. Thus, ecological community richness or abundance can be used to inform sampling of rare...

Demographic consequences of migratory stopover: Linking red knot survival to horseshoe crab spawning abundance Demographic consequences of migratory stopover: Linking red knot survival to horseshoe crab spawning abundance
Understanding how events during one period of the annual cycle carry over to affect survival and other fitness components in other periods is essential to understanding migratory bird demography and conservation needs. Previous research has suggested that western Atlantic red knot (Calidris canutus rufa) populations are greatly affected by horseshoe crab (Limulus polyphemus) egg...

Beach characteristics mitigate effects of onshore wind on horseshoe crab spawning: Implications for matching with shorebird migration in Delaware Bay Beach characteristics mitigate effects of onshore wind on horseshoe crab spawning: Implications for matching with shorebird migration in Delaware Bay
Disruption of food availability by unfavorable physical processes at energetically demanding times can limit recruitment of migratory species as predicted by the match–mismatch hypothesis. Identification and protection of disruption‐resistant habitat could contribute to system resilience. For example, horseshoe crab Limulus polyphemus spawning and shorebird stopover must match temporally...

Evaluation of single and two-stage adaptive sampling designs for estimation of density and abundance of freshwater mussels in a large river Evaluation of single and two-stage adaptive sampling designs for estimation of density and abundance of freshwater mussels in a large river
Reliable estimates of abundance are needed to assess consequences of proposed habitat restoration and enhancement projects on freshwater mussels in the Upper Mississippi River (UMR). Although there is general guidance on sampling techniques for population assessment of freshwater mussels, the actual performance of sampling designs can depend critically on the population density and...

Age and sex specific timing, frequency, and spatial distribution of horseshoe crab spawning in Delaware Bay: Insights from a large-scale radio telemetry array Age and sex specific timing, frequency, and spatial distribution of horseshoe crab spawning in Delaware Bay: Insights from a large-scale radio telemetry array
To study horseshoe crab Limulus polyphemus spawning behavior and migration over a large-spatial extent (>100 km), we arrayed fixed station radio receivers throughout Delaware Bay and deployed radio transmitters and archival tags on adult horseshoe crabs prior to their spawning season. We tagged and released 160 females and 60 males in 2004 and 217 females in 2005. The array covered...

Structured decision-making and rapid prototyping to plan a management response to an invasive species Structured decision-making and rapid prototyping to plan a management response to an invasive species
We developed components of a decision structure that could be used in an adaptive management framework for responding to invasion of hemlock woolly adelgid Adeleges tsugae on the Cumberland Plateau of northern Tennessee. Hemlock woolly adelgid, an invasive forest pest, was first detected in this area in 2007. We used a structured decision-making process to identify and refine the...
