Sam Droege
Sam is a Wildlife Biologist at the Eastern Ecological Science Center in Laurel, MD.
Sam has coordinated the North American Breeding Bird Survey Program, developed the North American Amphibian Monitoring Program, the BioBlitz, Cricket Crawl, and FrogwatchUSA programs and worked on the design and evaluation of monitoring programs. Currently he is developing an inventory and monitoring program for native bees, online identification guides for North American bees at discoverlife.org, and reviving the North American Bird Phenology Program.

Evaluation of specimen preservatives for DNA analyses of bees Evaluation of specimen preservatives for DNA analyses of bees
Large-scale insect collecting efforts that are facilitated by the use of pan traps result in large numbers of specimens being collected. Storage of these specimens can be problematic if space and equipment are limited. In this study, we investigated the effects of various preservatives (alcohol solutions and DMSO) on the amount and quality of DNA extracted from bees (specifically...

Tidal marshes: A global perspective on the evolution and conservation of their terrestrial vertebrates Tidal marshes: A global perspective on the evolution and conservation of their terrestrial vertebrates
Globally, tidal marshes are found in small pockets or narrow bands totaling only approximately 45,000 square kilometers. The combination of salinity, low floristic and structural complexity, and regular tidal inundation, as well as unpredictable catastrophic flooding, provides a unique selective environment that shapes local adaptations, including those that are morphological...

A unified strategy for monitoring changes in abundance of birds associated with North American tidal marshes A unified strategy for monitoring changes in abundance of birds associated with North American tidal marshes
An effective approach to species conservation involves efforts to prevent species from becoming threatened with extinction before they become listed as endangered. Standardized monitoring efforts provide the data necessary to estimate population trajectories of many species so that management agencies can identify declining species before they reach the point of endangerment. Species...
