We are a research lab in the School of Ocean Science and Engineering at The University of Southern Mississippi, based at the Gulf Coast Research Laboratory in Ocean Springs, MS. Our research focuses on environmental constraints on behavior, performance, and fitness of marine and estuarine invertebrates, and the strategies used by organisms to overcome these constraints. More specifically, this encompasses (1) plastic and adaptive behavioral and physiological responses to environmental change and environmental stress, (2) environmental effects on life histories, distributions, and population dynamics, and (3) anthropogenic impacts on organism-environment interactions. This research also has a strong applied focus, using ecophysiological approaches to address fisheries management and conservation questions. We work closely with local and regional management agencies to improve our understanding and management of coastal invertebrate species.

7/10/2018: Our Gulf-wide blue crab tagging program has tagged over 15,500 mature female blue crabs across the Gulf. For more information on this project, visit the project website here.
03/22/2018: Construction of our new boat, the Thalinectes, is complete. The boat was purchased with funds from the Coypu Foundation and built by Hanko's Metal Works in Berwick, LA. This boat will support research at the Chandeleur Islands and other coastal areas of the Gulf of Mexico. Pictures of the new boat here

10/6/17: Abby Kuhn successfully defended her M.S. thesis: Effects of temperature on growth and molting in blue crabs (Callinectes sapidus) and lesser blue crabs (Callinectes similis)! Congratulations, Abby!
10/1/17: We are recruiting exceptional M.S. and Ph.D. students to join The Craboratory in Fall 2018 and later semesters. Funding is available through competitive departmental fellowships. Please click here for more information and contact Zack if you are interested in discussing these opportunities.
8/15/17: The Craboratory welcomes Christian Hayes, a new Ph.D. student co-advised by Kelly Darnell and Zack Darnell.
6/1/17: The Craboratory (in collaboration with Kelly Darnell's Coastal Ecology and Seagrass Biology Lab) received funding from the NOAA RESTORE Act Science Program to investigate habitat use patterns of nekton in turtlegreass beds across the Gulf of Mexico. This project is a collaboration with Lee Smee (Dauphin Island Sea Lab), Charlie Martin (University of Florida), Penny Hall (Florida Fish and Wildlife Conservation Commission) and Brad Furman (Florida Fish and Wildlife Conservation Commission).
5/9/17: The Division of Coastal Sciences is offering graduate fellowships to qualified applicants for the M.S. or Ph.D. degrees. Please click here for more information and contact Zack if you are interested in discussing potential opportunities in the lab. Fellowship applicants for Spring 2018 admission will be reviewed beginning July 30th (application deadline October 1).
