September DOS Meeting – Connecting the Dots:Understanding Dramatic Declines in a Widespread Migratory Shorebird, theSemipalmated Sandpiper
September 18 @ 7:00 pm - 9:30 pm
Help DOS kick off our new program year at 7:00 PM onWednesday, September 18 at the Ashland Nature Center for a great evening withDr. David Mizrahi!
Connecting the Dots: Understanding Dramatic Declines in aWidespread Migratory Shorebird, the Semipalmated Sandpiper
In the talk, Dr. Mizrahi will discuss the challengesfacing migratory shorebirds and the research he has done in DE Bay and beyondto help us develop more effective conservation strategies.
Dr. David Mizrahi earned his PhD in Zoology atClemson University. His dissertation research focused on the ecology,physiology and behavior of Least and Semiplamated Sandpipers during springmigration staging periods in Delaware Bay. For the last 20 years he has heldthe position of Vice-president for Research and Monitoring at New JerseyAudubon. Dr. Mizrahi’s area of expertise is the ecology and conservation ofshorebirds with a primary focus on Semipalmated Sandpipers and other shorebirdspecies that winter in northern South America and migrate through the westernAtlantic region. Since 1995, he has conducted important research on the ecologyand behavior of shorebirds using soft-sediment habitats in Delaware Bay,including investigating the relationship between horseshoe crab eggavailability and weight gain potential in Semipalmated Sandpipers,relationships between habitat use and foraging strategies, and migrationphenology and connectivity using nanotag technology. In 2008, he initiated acomprehensive shorebird research and conservation program in northeastern SouthAmerica with partners in Suriname, French Guiana and Brazil. This includes workon spatial relationships between wintering, migrating and breeding populationsusing remote sensing techniques and stable isotopes, habitat use and foragingbehavior, physiological preparation for northward migration, the impacts ofshrimp aquaculture on foraging behavior and contaminants exposure, andaddressing illegal and unregulated shorebird hunting in the region. His currentresearch endeavors to develop apparent winter survival estimates forSemipalmated Sandpipers in the northern region of South America and use theseand similar data from migration staging and breeding areas to develop a fulllife-cycle, migration network model that helps to focus conservation strategiesfor the species.
