RED SWAMP CRAYFISH PROCAMBARUS CLARKII IN THE ATCHAFALAYA RIVER BASIN: BIOTIC AND ABIOTIC EFFECTS ON POPULATION DYNAMICS AND PHYSIOLOGICAL BIOMARKERS OF HYPOXIC STRESS A Dissertation Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The School of Renewable Natural Resources by Christopher P. Bonvillain B.S., Nicholls State University, 2004 M.S., Nicholls State University, 2006 August 2012 DEDICATION This dissertation is dedicated to my grandfather Sidney Kraemer Sr. (paw-paw Chackbay). He loved the swamps and wildlife of south Louisiana and enjoyed working in his swamp sanctuary, Malagay. My curiosity and passion for the outdoors is a piece of him that lives on in me. He would truly be amazed and delighted that his grandson was able to get a doctorate by working in swamps with gar, choupic, and crawfish. ii ACKNOWLEDGEMENTS I would like to thank my advisor Dr. Allen Rutherford for providing me with the opportunity to pursue my Ph.D. at LSU. He always found time for questions and discussions and made sure that funding was never an issue. He has continuously supported me both personally and professionally throughout my graduate tenure. I would also like to thank my committee members Drs. David Foltz, Christopher Green, Michael Kaller, William Kelso, and Glenn Thomas for their suggestions and review of my dissertation. Their insight and guidance were instrumental to developing, conducting, and most importantly, interpreting my research. I would also like to thank Dr. Robert Romaire for all of his help during my time at LSU and for sharing his knowledge of crawfish with me. He was always available to answer questions and provide expert opinions, and our conversations have greatly enhanced my understanding of crawfish biology and ecology. I also owe a debt of gratitude to Jerry Walls for his help identifying crawfish specimens and responding to my crawfish inquiries. Field and laboratory work would not have been possible without the assistance from numerous undergraduates, graduate students, and research associates. Jesse Bahm, Charlie Brown, Mike Campbell, Brooke Constant, Melissa Fries, Katherine Gauthreaux, Thorpe Halloran, Raynie Harlan, Lauren Hart, Zach Herrington, Daniel Hill, Jason Hughes, Jace Jarreau, Deb Kelly, Kayla DiBenedetto Kimmel, Johnny Meche, Catherine Murphy, Alex Perret, Adam Piehler, Mason Piehler, Will Sheftall, Matt Songy, Rachel Walley, Jonathan West, and Richard Williams all provided invaluable help (physical, intellectual, and mental) that made this research project possible. They endured the sometimes tedious lab work and braved the ever unpredictable Mother Nature and encounters with angry wasps, hornets, and pinching crawfish. I would also like to acknowledge my 120B officemates and friends, Thorpe Halloran (Thorpedo) iii and Will Sheftall. Their unwavering support and friendship and willingness to chat over a cold beverage were always greatly appreciated. Thanks to Deb Kelly and Cheryl Duplechain for providing endless encouragement, support, and most importantly laughter throughout my time in RNR. A special thanks to Rotary District 6200 for providing me with the opportunity of lifetime to visit Queensland, Australia. This experience has helped enrich my education and broaden my global perspectives. Many thanks to Rotarians of Rotary District 9600 for accepting me into their homes, immersing me in their culture, and providing me with memories and friendships that will last a lifetime. Quenton Fontenot and Allyse Ferrara have both contributed immensely to my professional and personal growth and I cannot thank them enough for everything they have done for me through the years. They have helped and inspired me to achieve more than I ever thought possible, and I would not have accomplished all that I have if it were not for them. I owe a special thanks to Catherine Murphy for more things than I can list here. She has spent countless hours assisting me with everything from stats to field work to feeding me when I was stuck in the office trying to put words on paper. She has been my biggest supporter and has given me the strength and encouragement I needed to complete this dissertation. I want to thank my parents, Larry and Shirley, for always believing in me. They have supported me throughout my long and arduous academic career and have sacrificed a great deal to help me achieve my goals. Finally, to my two buddies, Cocoa and Bailey, thanks for always being happy to see me and not caring about p values, publications, anaerobic pathways, or Procambarids. iv TABLE OF CONTENTS DEDICATION. ............................................................................................................................... ii ACKNOWLEDGEMENTS ........................................................................................................... iii LIST OF TABLES ........................................................................................................................ vii LIST OF FIGURES ....................................................................................................................... ix ABSTRACT ................................................................................................................................. xiii CHAPTER 1: GENERAL INTRODUCTION ...............................................................................1 Study Area ...............................................................................................................4 Crayfish vs Crawfish................................................................................................7 Dissertation Synopsis ...........................................................................................................8 Literature Cited ....................................................................................................................8 CHAPTER 2: BIOTIC AND ABIOTIC EFFECTS ON RED SWAMP CRAYFISH PROCAMBARUS CLARKII POPULATION CHARACTERISTICS IN THE ATCHAFALAYA RIVER BASIN................................................................................................13 Introduction ........................................................................................................................13 Study Area .............................................................................................................17 Methods..............................................................................................................................18 Sample Locations ...................................................................................................18 Field Collections ....................................................................................................18 Data Analysis .........................................................................................................23 Results ................................................................................................................................27 Water Level and Physicochemistry .......................................................................27 Crayfishes ..............................................................................................................29 Population Characteristics .....................................................................................33 Discussion ..........................................................................................................................57 Literature Cited ..................................................................................................................66 CHAPTER 3: ACUTE PHYSICOCHEMICAL EFFECTS IN A LARGE RIVER- FLOODPLAIN SYSTEM ASSOCIATED WITH THE PASSAGE OF HURRICANE GUSTAV .......................................................................................................................................74 Introduction ........................................................................................................................74 Study Area .............................................................................................................76 Methods..............................................................................................................................77 Results ................................................................................................................................79

  • THE ECOLOGY of BOTTOMLAND HARDWOOD SWAMPS of the SOUTHEAST: a Community Profile
    Biological Services Program FWS/OBS-81 /37 March 1982 THE ECOLOGY OF BOTTOMLAND HARDWOOD SWAMPS OF THE SOUTHEAST: A Community Profile I 49.89 ~~:137 Fish and Wildlife Service 2 c. U.S. Department of the Interior The Biological Services Program was established within the U.S. Fish and Wildlife Service to supply scientific information and methodologies on key environmental issues that impact fish and wildlife resources and their supporting ecosystems. The mission of the program is as follows: • To strengthen the Fish and Wildlife Service in its role as a primary source of information on national fish and wild­ life resources, particularly in respect to environmental impact assessment. • To gather, analyze, and present information that will aid decisionmakers in the identification and resolution of problems associated with major changes in land and water use. • To provide better ecological information and evaluation for Department of the Interior development programs, such as those relating to energy development. Information developed by the Biological Services Program is intended for use in the planning and decisionmaking process to prevent or minimize the impact of development on fish and wildlife. Research activities and technical assistance services are based on an analysis of the issues, a determination of the decisionmakers involved and their information needs, and an evaluation of the state of the art to identify information gaps and to determine priorities. This is a strategy that will ensure that the products produced and disseminated are timely and useful. Projects have been initiated in the following areas: coal extraction and conversion; power plants; geothermal, mineral and oil shale develop­ ment; water resource analysis, including stream alterations and western water allocation; coastal ecosystems and Outer Continental Shelf develop­ ment; and systems inventory, including National Wetland Inventory, habitat classification and analysis, and information transfer.

  • The Atchafalaya Basin
    7KH$WFKDIDOD\D%DVLQ5LYHURI7UHHV The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers (USACE), is monitoring the basin to determine environmental effects of flood-management practices. The Atchafalaya Basin in south-central Louisiana includes the largest contiguous river swamp in the United States and the largest contiguous wetlands in the Mississippi River Valley. The basin includes 10 distinct aquatic and terrestrial habitats ranging from large rivers to backwater swamps. The basin is most noted for its cypress-tupelo gum swamp habitat and its Cajun heritage. Water in the Atchafalaya Basin originates from one or more of the distributaries of the Atchafalaya River.

The basin’s dense bottomland hardwoods, cypress- tupelo swamps, overflow lakes, and meandering bayous provide a tremendous diversity of habitat for many species of fish and wildlife. Ecologists rank the basin as one of the most productive wildlife areas in North America. The basin also supports an extremely productive sport and commercial fishery, and provides unique recreational opportunities to hundreds of thousands of Americans each year. Wildlife Every year, thousands of migratory waterfowl winter in the overflow swamps and lakes of the basin, located at the southern end of the great Mississippi Flyway. The lakes of the lower basin support one of the largest wintering concentrations of canvasbacks in Louisiana. The basin’s wooded wetlands also provide vital nesting habitat for wood ducks, and support the nation’s largest concentration of American America’s Great River Swamp woodcock.

While recent evolutionary studies have focused on a few of these species, here we provide a comprehensive phylogenetic estimate of relationships among the species within the genus. We sequenced three mitochondrial gene regions (COI, 16S, and 12S) and one nuclear region (28S) from 40 species of the genus Euastacus, as well as one undescribed species. Using these data, we estimated the phylogenetic relationships within the genus using maximum-likelihood, parsimony, and Bayesian Markov Chain Monte Carlo analyses. Using Bayes factors to test diVerent model hypotheses, we found that the best phylogeny supports monophyletic groupings of all but two recognized species and suggests a widespread ancestor that diverged by vicariance.
