Saturday Science for Students with Dr. John Tanacredi: "Alien Crabs"

The four living species of horseshoe crabs face a set of growing threats to their survival, including the erosion and/or man-made alteration of essential spawning habitat, coastal pollution, and overfishing. Horseshoe crabs are “living fossils”, with a more than 200 million year evolutionary history. Their blood provides a reagent, known as Limulus amebocyte lysate or LAL, that clots in the presence of minute quantities of bacterial endotoxin; the LAL test is the state-of-the-art methodology used to ensure that pharmaceuticals and surgical implants are free of contamination. Horseshoe crabs are an integral part of the food web in coastal marine ecosystems, and their eggs provide essential food for shorebirds in the Delaware Bay estuary each spring. The commercial fishery for horseshoe crabs, which utilizes animals for bait, contributes to the economies of coastal communities.

John T. Tanacredi, Ph.D. is Professor of Earth and Environmental Studies in the Biology, Chemistry and Environmental Studies and Director of the Center for Environmental Research and Coastal Oceans Monitoring (CERCOM) facility, of Molloy College. In addition, he is a Research Associate at the Wildlife Conservation Society; Aquarium for Wildlife Conservation-Osborn Laboratories of Marine Science, visiting scientist at The American Museum of Natural History formally in the Department of Invertebrate Zoology; Research Associate at the Lamont Doherty Earth Observatory, Columbia University, Earth Institute; a member of the Executive Committee of the Board of Oceans and Atmosphere, National Association of State Universities and Land Grant Colleges NASULGC and the chair of the Conservation Committee of the Explorers Club. He has over 55 peer reviewed scientific publications and 5 books, and has published widely on conservation ecology, ecotoxicology and the horseshoe crab. His most recent book “Conservation and Biology of Houseshoe Crabs,” Springer, 2009 was one of the initiating factors in conducting the first Asian Horseshoe Crab Conference in Hong Kong in 2011. Before coming to Molloy College from 1978 to 2001 he was a Research Ecologist for the National Park Service, Gateway National Recreation Area as Chief of the Division of Natural Resources. From 1974-1978 he was an Environmental Analyst of the U.S. Coast Guard, Bridge Administration; and from 1968 to 1970 he was a U.S. Navy meteorologist “Hurricane Hunter”. Dr. Tanacredi received his doctorate in Environmental Health Engineering, from The Polytechnic University, today NYU Polytechnic, M.S. degree in Environmental Health Sciences from Hunter College, CUNY and BS in Biological Sciences from Richmond College, CUNY.
