       I began my career as a fisheries biologist, having majored in biology at Florida State University (B.S.), and fisheries at the University of Massachusetts (M.S.) and Virginia Tech (Ph.D.).  I discovered the diversity of other organisms that also inhabit freshwater systems during my graduate programs, and have gradually added zooplankton, macroinvertebrates, and most recently, aquatic plants to my research interests.  Louisiana is a wonderful location for an aquatic ecologist, with highly productive sub-tropical rivers, streams and lakes that support a huge diversity of aquatic life, both native and introduced.  The Atchafalaya River Basin is one of the few large bottomland hardwood floodplains left in the U.S., and has provided numerous opportunities for research projects.  There are always new questions to ask, and I have been fortunate to work with many good people at state and federal agencies that have provided funding for my studies.

 

 

 

Teaching
          I like teaching and have developed several courses at LSU over the past 20 years.  RNR 1001 is particularly enjoyable (although enrollment has increased to 360 students a semester), as it is a general education elective, with the majority of students in the class coming from disciplines outside of natural resources. 
RNR 1001 - Natural Resource Conservation, Spring and Fall, 3 hours
RNR 1002 - Issues in Natural Resource Management, Spring and fall, 1 hour discussion
RNR 2002 - Introduction to Fisheries and Aquaculture, Fall, 3 hours, co-taught with Dr. Robert Reigh,  Aquaculture
RNR 4023 - Marine Fisheries Resources, Spring, 3 hours
RNR 4040 - Fisheries Management, Fall, 3 hours
RNR 4106 - Techniques in Fisheries and Limnology, Intersession, 2 hours, co-taught with Dr. Michael Kaller
RNR 7020 - Ecology of Fishes, Spring, 3 hours, for graduate students interested in all aspects of fish ecology and biology

 

 

 

Research
     Much of the research I have been involved with has focused on the influence of habitat characteristics and water quality on aquatic biota in freshwater habitats.  The rather broad scope of my research interests has yielded a diversity of thesis and dissertation topics, but I have found that I most enjoy learning new things with my students as they pursue their graduate education:

Current Research Projects:

 

Status of fishes and mussels of concern in southwestern Louisiana

     We completed a 2-year project on the status of several Louisiana fishes of concern in the southeastern portion of the state, and have not begun a 2-year project investigating the population status and distribution of several fishes and mussels of concern in streams located in the southwestern portion of the state.  We will use backpack, barge, and boat electrofishing gear supplemented by seining to sample fish communities in streams in the Calcasieu, Mermentau, and Sabine watersheds, and will also be collecting data on habitat and water quality conditions and macroinvertebrate community composition, particularly the abundance and distribution patterns of several rare freshwater mussels.  These streams were severely impacted by Hurricane Ike in 2008, and it will be particularly interesting to investigate the status of biotic communities in these streams.

Relationships among water quality, habitat, and biotic structure in the Atchafalaya River Basin
We continue to work on assessment of habitat, water quality, and fish community structure in the Atchafalaya River Basin, and several recent graduate students have been addressing research topics in the Basin ranging from aquatic plant community structure and epiphytic invertebrate ecology to the physiology and life history characteristics of red swamp crayfish and floodplain use by Basin larval fishes.  The focus of the Atchafalaya Basin Project is to reduce the effects of channelization, canal construction, and other hydrological modifications that have occurred over the last century and restore the natural hydrology across the floodplain.  We have a large monitoring project in the Basin, whereby we record water quality, depth, flow, and habitat conditions at over one hundred locations biweekly, and we also electrofish at approximately 30 locations.  We have had numerous students who addressed various ecological questions in their theses and dissertations that have focused on habitat associations of larval, juvenile, and adult fishes, macroinvertebrates, and aquatic plant communities.  Exotic plants, particularly water hyacinth Eichhornia crassipes and hydrilla Hydrilla verticillata, currently dominate aquatic habitats in the Basin, and are significantly affecting water quality, habitat structure, and biotic community dynamics within the littoral zone.      

   

   
     Water quality problems are evident as the Basin drains during the latter stages of the flood pulse.  The black (low dissolved oxygen) water results from prolonged floodplain inundation, lack of flow, and high rates of decomposition in the flooded forest.        You can see the dense hydrilla stands infesting a canal in the lower Basin.  Without boat traffic, this canal would be completely choked with hydrilla, which is often decomposing under surface mats of water hyacinth and common salvinia, reducing dissolved oxygen levels.        During the flood pulse, bottomland forests dominated by cypress trees are inundated by sediment-laden river water.  Reduced stagnation and improved water movement onto and out of the floodplain would significantly improve aquatic habitat conditions.

 

 

Habitat, water quality and fish and invertebrate community composition in the newly flooded Mollicy Tract on the Ouachita River
     The Mollicy Tract on the upper Ouachita River in northeastern Louisiana has historically been separated from the Ouachita River by a levee system.  Recent floods have breached the levee, and the U.S. Fish and Wildlife Service in conjunction with the Nature Conservancy and the Louisiana Department of Environmental Quality are planning to permanently remove sections of the levee to allow the Ouachita River to access this historical floodplain.  We have project in which we are assessing water quality, habitat structure, larval fish abundance, invertebrate community composition, and fish community structure in the Mollicy Tract as well as a natural floodplain area on the west side of the river.  The project is designed to follow the development of more lotic habitat characteristics and aquatic communities as the floodplain matures.

Current Thesis and Dissertation Research:
Growth and condition of native Louisiana and Florida largemouth bass in Louisiana lakes

Fries, M.  2010.  Environmental influences on individual growth and genetic composition of Louisiana largemouth bass stocks.  M. S. Thesis.  In progress.   

     Melissa is focusing her research on 12 lakes located throughout Louisiana that have been stocked with Florida largemouth bass over the past two decades.  We have noticed substantial differences in bass growth, introgression, and individual condition these lakes, and Melissa is measuring numerous morphological, water quality, and habitat related variables in these lakes to see if we can determine why lakes differ in the composition and growth of their resident bass populations.   

             
     
Submerged woody structure is one of the variables that may influence largemouth bass in these lakes   Another important habitat variable that may be affecting bass growth and condition is macrophyte density, particularly hydrilla, or in this case, duckweed   Melissa is recording water quality with in situ monitors and basin morphology with a digital recording fathometer   Everybody in Louisiana likes crayfish

 

Fish community habitat relationships in southeastern Louisiana streams

Ward, B. M.  2009.  Effects of land use and habitat on stream fish assemblages in tributaries of the lower Bogue Chitto watershed, Washington Parish, Louisiana.  M. S. Thesis.  In progress.

     Brian is finishing up a project looking at the influence of water quality, reach-scale habitat, and watershed land use on the structure of fish communities in several tributaries of the Bogue Chitto River watershed in southeastern Louisiana.  He visited his study sites four times each to get a good idea of community composition and variability within and among years, and we are curious whether we can detect land use effects on fish distribution and abundance.  He has found substantial variability in physicochemical characteristics among sites, and we are analyzing his data to see if these site differences are reflected in the resident fish communities.

 
   
   
Numerous fishes were found in Brian's study streams, including striped mullet   Measured habitat characteristics included depth, flow, woody debris abundance, and substrate composition   Backpack electrofishing units worked well in these streams, despite low specific conductance

 

Disturbance ecology

West, J. L.  2010.  Disturbance ecology of streams in southeastern Louisiana.  Ph.D. Dissertation. 

     Jonathan is just beginning his research on the environmental structuring forces that shape the structure and function of coastal plain streams.  We have numerous streams in the eastern portion of the state that were significantly impacted by Hurricane Katrina, and he would like to follow temporal  patterns of community metabolism, periphyton abundance, and habitat diversity in these streams relative to streams that received little if any storm impact.  Woody debris movement and the effects of woody debris abundance on stream habitats will likely play a major role in his research, as these streams are highly dynamic in terms of discharge and habitat structure. 

     
 
During the growing season, streams throughout southeastern Louisiana are often characterized by low gradients, fine substrates, high organic loads, and marginal dissolved oxygen levels.   Although often supporting high densities of woody debris, many streams offer little habitat complexity in the form variable depths, flow velocities, and substrate types, yet often yield a relatively high diversity of fishes and invertebrates.

 

Life history of alligator gar
DiBenedetto, K. C.  2009.  Life history characteristics of alligator gar, Atractosteus spatula, in south Louisiana.  M.S. Thesis.

     Kayla is investigating several basic life history parameters of alligator gar, a species that has declined throughout much of its historic range, but appears to be thriving in south Louisiana and currently supports a small commercial fishery.  She is looking at aging techniques, growth, and reproductive ecology, and has collected over 300 gar for her project with the help of a commercial fisherman.
