ACKNOWLEDGMENTS Daniel J. Bereza, Samuel L. H. Fuller, H. Dickson Hoese and the late Nell B. Causey provided valuable assistance in the many years of my studies. My wife, Gail, and my children, Macky, Daniel, and Caroline, helped in many ways. I also thank my parents and my brothers. Colin Fake and the Drafting Department of Sowela Technological Institute, Lake Charles, Louisiana, are also acknowledged. Sabbatical leave for the spring semester (1996) provided me with the opportunity to complete this book. Dr. William Richardson and the LSU System are acknowledged for the opportunity. Dr. Barry Good and the faculty in my division supported me and covered my tracts so that I could create this book. The staff at LSUE, especially Bobbie Richard and Denise Foret, provided assistance. The librarians, Sue Forrest and Cathy Good, found some of those rare papers! The list of colleagues who helped me to do this work is long. Many of them are individually acknowledged by having species or subgenera named for them. All of these authors and colleagues have made worthy contributions, and I thank them. People that I have to mention include Ron Dimock, Dale Edwards, Charles Stagg, Steve Parris, Charles Allen, James Cordes, Darryl Clark, Bruno Borsari, Harland Guillory, Steven George, Steven Shively, Roy McLaughlin, Ray Hartenstine, Veryl Board, Doug Shelton, Paul Hartfield, John Harris, Mark Farr, Art Bogan, Ronnie Bouchon, Micheal Poirrier, Jack Burch, Mary Curry, Betty Everitt, Bill Heard, Sylwyn Roback, James L.

Without these colleagues, it would not have been possible to do this! My special thanks to Robert Wolcott, James Wilson, Rodger Mitchell, Ron Dimock, John Conroy, and Ian Smith. They laid the groundwork for North American mites in mussels. I gratefully acknowledge the Jessup Grant of the Academy of Natural Sciences of Philadelphia for my Jessup Fellowship (1978). This opportunity gave me the chance to study in the academy's mollusk collections. Many other museums also allowed me to examine mussels for mites; these include the Ohio State University Museum of Zoology, Smithsonian Institution, National Museum of Canada, and the Museum of Zoology of the University of Michigan. Types of mites were borrowed from the Marshall Collections of the Field Museum of Natural History in Chicago and the Museum of Comparative Zoology at Harvard University. Many years ago the Graduate Student Organization at the University of Southwestern Louisiana gave me funds to search the southeastern United States for mites in mussels. That impetus provided the bulk of the mites in my holdings. Many specimens of mites were provided by Samuel Fuller, Dan Bereza, Jim Wilson, and others.

PREFACE The purpose of this book is to provide the data accumulated from stations across North America. This compilation of data on collections allows the reader to not only discover the vast amount of data but also the differences among samples. The accumulation of data on species compositions at varied stations provides the bases for many different kinds of research. The need for such data in biogeography and community ecology is evident. However, the data also serve as a baseline set for comparison with future collections. The freshwater ecosystems are changing at unbelievable rates. While a few streams are being restored, the vast majority are being systematically destroyed by human wastes and development. Agriculture and its erosion is literally smothering mussels. The loss of the mussels and snails is singular in its ability to completely destroy the integrity of the benthos of our waterways. The runoff of agricultural chemicals apparently destroys the mites in the mussel communities. Collectively, the mussels and their mites are immediately threatened and endangered with extinction in the early part of the next decade.

INTRODUCTION

Water mites which occur in freshwater mussels and snails include two major taxa, Najadicola

and Unionicola. These mites are the subject of a four volume treatise of which this book is a part

(Vidrine 1996a, 1996b, and 1996c). Twenty-five years of personal experience with these mites

(1971-1996) are my investment in these mites and their biology.

The ecology of Unionicola and their hosts have undergone several major discoveries:

1. larvae of these mites parasitize chironomids (Jones, Hevers, Simmons, Smith, Dimock, and

Edwards)

2. host specificity of larvae, nymphs, and adults (Mitchell, Wilson, Dimock, Edwards, and Vidrine)

3. parasitism by tissue consumption (Baker)

4. host location (Welsh, Dimock, and Jack)

5. community structure (Dimock, Edwards, and Vidrine).

6. sensitivity of mites to agricultural runoff (George and Vidrine).

7. predation of one species of mites by another (Downes)

8. host resource partitioning (Mitchell)

9. population structure and dynamics controlled by mites (Mitchell and Dimock)

10. high diversity of mites in mollusk-rich communities (Wolcott, Mitchell, Wilson, and Vidrine)

These discoveries and many others regarding these mites signal the potential dynamic nature of the

ecological web of relationships among not only species of Unionicola but also species of their hosts.

Najadicola is also part of this community, and, for the purposes of general information, it is included

here with the many species of Unionicola.

This volume contains community structure data in the format of collection data for 768 stations

divided into 20 geographically identified groups. This book contains data from Robert Dobson and

Thomas Calnan, both who constructed excellent theses showing community structures of these mites

and their hosts. The stations are listed in an order that more or less parallels the known mussel

biogeographic provinces; however, some exceptions are made to handle the data obtained from Canada

and Mexico as distinct units and to handle several museum collections.

The methods of seeking these mites are different from those traditionally used by acarologists in

search of water mites. Traditionally water was sampled with nets, sieves, and other devices, whereas this

author searches the actual host animals, namely mussels and snails, from each station. As a result, the

data are reported in a tabular manner with the host mollusks and their mites. In all cases, both the hosts

and the mites are identified to the best of my ability and many malacologists. The identification of both

hosts and mites facilitates later discussions of host specificity and population biology.

A world-wide database similar to this is greatly desired. It would likewise facilitate discussions

of host specificity, population biology, evolution, and biogeography. The decimation of freshwater

mollusk communities worldwide (Bogan 1993 and Cushman 1995) indicates the decimation of a

likewise diverse mite community, which parasitizes these mussels.

The mussel names follow Turgeon et al. (1988), Hoeh (1990), Bogan (1993), and Daniel Bereza

(personal communication). Snail names follow Burch (1989). The mite names are those accepted by this

author.

The seventh group includes collections (tables 300-363) made during an extensive survey of the upper Mississippi River by the members of the Academy of Natural Sciences of Philadelphia. Samuel L. H. Fuller and his crew diligently collected mites from mussels and snails. Their work created a data base for the upper river, which is presented here. Vials often contained numerous mites, which were obviously taken from more than one mussel. I do not know how many mussels were examined; however, the incidences based on repeated occurrences in several to numerous stations can be used to indicate frequencies. All of the data is represented as singular cooccurences in the calculations regarding number of hosts infested, although no numbers are used with these data in these tables. The use of numbers would possibly indicate a piece of information that I do not have. 300. Minnesota. Washington County.

SUMMARY AND CONCLUSIONS This volume contains community structure data that is formatted as collection data for 768 stations divided into 20 geographically identified groups. The accumulation of similar data on hosts and mites facilitates later discussions of host specificity, community ecology, vicariance biogeography, and population biology. It is essential for comparative community structure studies. One major advantage of parasite communities over others is that the habitat they live in, the host, has such a well defined structure...The host microcosm is replicated through time and space much more so than habitats for most other organisms. Therefore, the study of comparative community structure is very powerful (Price 1986). Unfortunately, there is currently little overlap between parasite groups for which we have extensive community ecological information and groups for which we have extensive phylogenetic information (Brooks and McLennan 1993). The mussel and mite community ecological information is extensive enough for preliminary analyses and for discussions of vicariance biogeography and the geographic mosaic theory of coevolution (Thompson 1994). A world-wide database similar to this is greatly desired. It would likewise facilitate discussions of host specificity, population biology, evolution, and vicariance biogeography on a global scale. The development of this data base is dependent on surveys of streams of the world prior to their decimation. The decimation of freshwater mollusk communities worldwide (Bogan 1993 and Cushman 1995) indicates the loss of a likewise diverse mite community, which parasitizes these mussels.

BIOGRAPHICAL SKETCH Malcolm F. Vidrine received his Ph.D. in Biology at the University of Southwestern Louisiana in 1980. His thesis was centered upon the water mites parasitizing freshwater mussels in eastern North America. In 1978, he was awarded a Jessup Fellowship by the Academy of Natural Sciences of Philadelphia, where he studied the Academy's mussel collections. He is currently Professor of Biology in the Division of Sciences at Lousiana State University at Eunice. He is the author and/or coauthor of 7 books and more than 70 scientific and popular articles on a wide variety of topics including leprosy in armadillos, trematodes, leeches, mosquitoes, rotifers, butterflies, dragonflies, plants/wildflowers, prairie restoration, mussels, and mites. He serves as Vice-President of the Cajun Prairie Habitat Preservation Society, through which he has been actively restoring a prairie in a 10 acre city park in Eunice. He has been married to Gail Jeanne Quillman for 12 years, and they have two children, Daniel and Caroline. His older son, Macky, is a musician in Atlanta, Georgia.
