About The Author

Dr. Wirgin is an Associate Professor in the Department of Environmental Medicine of the New York University School of Medicine.

His research is in two broad areas; a) use of DNA markers in the management of North American anadromous and marine fish populations, and b) understanding the molecular effects of contaminants on natural populations of fishes in the New York-New Jersey area. His groundbreaking study published in Science on the molecular mechanism of resistance to PCBs and dioxins in Atlantic tomcod demonstrated that evolution in impacted populations chronically exposed to contaminants can be much more rapid than previously thought. Furthermore, his recent global gene expression studies in these same populations using RNA-Seq indicate that the difference in the number and identity of genes differentially expressed in resistant versus sensitive populations is astounding.

                       

Use Of DNA Analysis In Identifying The DPS And Population Origin Of Highly Migratory Atlantic Sturgeon

There are between 25 and 27 species of sturgeons in the temperate waters of the Northern hemisphere, and populations in all are depleted or threatened with extirpation because of overharvesting and habitat alteration. Atlantic sturgeon Acipenser oxyrinchus oxyrinchus was at one time distributed on both sides of the Atlantic Ocean, but the last European populations in the Baltic were believed extirpated in the 1960s. Atlantic sturgeon are anadromous, historically spawned in 38 rivers along the North American Atlantic Coast from...
