M.S. ASSISTANTSHIPS IN MARINE AND ENVIRONMENTAL BIOLOGY, NICHOLLS STATE  
UNIVERSITY

We seek highly motivated students to fill two funded M.S. assistantships in the 
laboratory of Dr. Zack Darnell at Nicholls State University in Thibodaux, LA. 
More 
information on Dr. Darnell’'s research can be found at 
http://www.nicholls.edu/zdarnell. Assistantships will begin in January, 2016 
and include a stipend of 
$18,000 per year. The students selected for both assistantships will be fully 
integrated members of the project teams and will contribute to study design, 
collection and analysis of data, and manuscript preparation. Prior research 
experience is preferred. 

ASSISTANTSHIP 1: LINKING BLUE CRAB ABUNDANCE, GROWTH, AND MORTALITY TO MARSH 
FRAGMENTATION AND SUBMERGED AQUATIC VEGETATION 
COVER 
The overarching goal of this project is to determine the effects of changing 
coastal landscapes on blue crab populations in Terrebonne Basin, a region of 
coastal Louisiana supporting a large blue crab fishery but experiencing 
substantial marsh fragmentation and land loss. The student will conduct field 
surveys of 
blue crab abundance and field experiments examining growth and mortality across 
a range of fragmentation conditions. This is a collaborative project with The 
Water Institute of the Gulf, and the student will work closely with Water 
Institute personnel. 

ASSISTANTSHIP 2: MIGRATORY MOVEMENTS AND FISHING MORTALITY OF THE LOUISIANA 
BLUE CRAB SPAWNING STOCK
This project investigates the timing and route of the blue crab spawning 
migration, the processes contributing to mortality during this critical phase 
of the life 
cycle, and the potential for sperm limitation in the Louisiana blue crab 
spawning stock. The student will work with local commercial crabbers to conduct 
a 
mark-recapture study in the Terrebonne and Pontchartrain Basins, and will use 
recaptured and returned crabs to examine sperm stores and reproductive 
potential. 

ABOUT THE UNIVERSITY AND DEPARTMENT: Dr. Darnell is an assistant professor in 
the Department of Biological Sciences at Nicholls State University, a 
comprehensive regional university located in Thibodaux, Louisiana. Nicholls
