George Jackman Finding Handgun in Bronx River

George Jackman

George completed his Ph.D. on the stock structure of winter flounder, using the elemental composition of otoliths.  His sites include New York Harbor, Long Island Sound, and Georges Bank.  Otolith expert Karin Limburg of SUNY-ESF is serving as a co-advisor.  Although George is a former New York City police detective, the 'hot' gun was found by accident in 2012 during an eel survey  on  the bottom of the Bronx River.

Colin Grubel

Colin worked on the feeding habits of Double-crested Cormorants in New York Harbor.  This includes six years of field data from South Brother and Hoffman and Swinburne Islands, work with captive cormorants, and dissections of sacrificed specimens from Lake Ontario (to better understand pellet and bolus formation).  His work, greatly assisted by New York City Audubon, was covered in the New York Times (see link)

Ivana Roman Seining with John Waldman in Uur River, Mongolia

Ivana Roman
Ivana is an advanced undergraduate from Serbia who accompanied me to Mongolia in 2011.  In the photo she is seining for loach and  other small fishes to analyze in her study of the recolonization of Lake Hovsgol.  By comparing DNA (using coalescent analysis) from specimens from the lake and from the refugium of the Uur River, we estimated the  times of recolonization  of this great lake following deglaciation. 

Peter Malaty

Peter--currently employed by the NewYork State Department of Environmental Conservation--wrote his Masters thesis on the inshore fishes of Long Island.  In 2010, Peter seined intensively at the same sites and using the same gear as New York State biologist Greeley  surveyed some 72 years earlier.  Peter's work showed some significant changes, such as a steep decline in the American eel and was covered in Newsday.

Katie Sheridan

Katie researched a Masters degree from afar, in New Zealand working on the critically endangered teal-duck species called Pateke.  Her research emphasizes microgeographic distributions and habitat use within the Zealandia Wildlife Sanctuary.

Matt Tozer

Striped bass have not undergone a molecular analysis of their population relationships across their entire range.  Using microsatellite markers, Matt investigated DNA from specimens from the three major migratory stocks (Hudson, Delaware, Chesapeake) and from residential or less migratory populations from Canada to Florida and from the Gulf of Mexico drainage.  Matt performed the bench work in my colleague Isaac Wirgin's lab.

Nick Zito

Nick graduated Queens College with honors in 2013.  In his final semester he worked on a research project--to develop an annotated list and bibliography of all the non-native species presently found in, or expected to be encountered, in New York Harbor.  We are currently developing this list for publication, while Nick works at his new position as a forester with the New York City Department of Parks and Recreation.

Jonelle Orridge

In puddles on the dirt roads of the Hackensack Meadowlands and elsewhere in the northeast lives a truly odd invertebrate, the clam shrimp.  Jonelle Orridge contributed to our scant understanding of this crustacean with her 2011 Ph.D. dissertation titled Genetic, Morphological and Ecological Relationships Among Populations of the Clam Shrimp, Caenestheriella gynecia.

Tiffany Medley

With all the interest in restoration of oysters in New York Harbor using cultured stock, little attention has been paid to its wild population.  Tiffany completed her Ph.D. in 2010, titled Wild Oysters Crassostrea virginica, in the Hudson River Estuary: Growth, Health, and Population Structure.  Tiffany currently holds a position as a lecturer at Monmouth State College in New Jersey.

Susan Stanley

Vernal pools--only seasonally inhabitable by aquatic creatures--have unique ecologies.  Susan Stanley studied a set of vernal pools in New York City and reference pools in non-urban areas for a Masters thesis completed in 2012, titled Vernal Pools in an Urban Landscape in New York City.  Susan works for the Natural Resources Group of the New York City Department of Parks and Recreation.

Michael Bednarksi

The phenomenon of striped bass wintering in non-natal estuaries has been little studied.  Mike examined the movements of stripers during the cold months in the Thames River in Connecticut, a well-known and heavily fished seasonal aggregation with his 2007 Masters thesis,Overwintering Biology of Striped Bass (Morone saxatilis) in the
Thames River Estuary, Connecticut.  Mike subsequently completed a Ph.D. on sturgeon at the University of Georgia and now works as a diadromous fish restoration specialist for the State of Massachusetts.
