INFORMATION TO USERS This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete. 4. The majority of users indicate that the textual content is of greatest value, however, a somewhat higher quality reproduction could be made from "photographs" if essential to the understanding of the dissertation. Silver prints of "photographs" may be ordered at additional charge by writing the Order Department, giving the catalog number, title, author and specific pages you wish reproduced. 5.

COOK 1 Department of Natural Science, Peru State College, Peru, Nebraska, U.S.A. and 2 Department of Biological Sciences, Sam Houston State University, Huntsville, Texas 77341-2166, U.S.A. ABSTRACT: Trichurispora wellgundis n. g., n. sp. (Apicomplexa: Eugregarinida: Hirmocystidae) is described from the adults of the water scavenger beetle Tropisternus collaris (Coleoptera: Hydrophilidae) collected from B A Steinhagen Lake in the Cherokee Unit of the Big Thicket National Preserve, Tyler County, Texas, U.S.A. Trichurispora is distinguished from known genera of Hirmocystidae by a distinct ‘‘trichurisiform’’ oocyst that is hesperidiform in outline, comprising a fusiform oocyst with shallowly ovoid terminal knobs or caps. Oocyst residua are present but confined to a central fusiform residuum vacuole. Adult and larval hydrophilid beetles represent distinctly different opportunities for parasite colonization and diversification. Gregarines have been reported from both adult and larval hydrophilid beetles, but no species and no genus is reported from both adult and larval hosts. In fact, gregarine taxic richness is often more disparate between adult and larval beetles of the same species than between host beetle species. This is the first report of a septate gregarine from an adult hydrophilid beetle in the Nearctic.

Łódzki 3, 10-727 Olsztyn, Poland, e-mail: [email protected] ABSTRACT. The study involved the analysis of the foregut content of 120 adult specimens of Colymbetes fuscus and C. striatus collected in aquatic habitats in the Biebrza Marshes (Poland) and the Zehlau Peatbog (Russia). The gut content comprised animals (including eggs of aquatic invertebrates), plants and detritus. Larvae of Ephemeroptera were common in beetles from the Biebrza Marshes. The gut content also included Dytiscidae, Cladocera, Chironomidae and other Diptera, Copepoda, other insects, other Coleoptera aquatica, Heteroptera, Acari, Ostracoda, Culicidae and Asellus aquaticus. In the Zehlau Peatbog, both of the beetle species fed predominantly on the larval stages of Chironomidae (Diptera). The gut content also included adult terrestrial insects and spiders. KEY WORDS: predation, diving beetles, the Zehlau Peatbog, the Biebrza Marshes, Dytiscidae. INTRODUCTION Predation is one of the dominant antagonistic relationships integrating a biocoenosis. In spite of the availability of a rich literature relating to food consumed by predatory insects, our knowledge of the diet of Dytiscidae is still scarce. It is the larval stages of these beetles that seem to have been examined the most thoroughly (JOHANSSON & NILSSON 1992, YOUNG 1967, YOUNG & SPERLING 1986, PEARMAN 1995, LE LOUARN & CLOAREC 1997, GAUTAM & GOUTAM 2006, INODA 2012).

    ARTICLE IN PRESS Organisms, Diversity & Evolution 7 (2008) 255–269 www.elsevier.de/ode A genus-level supertree of Adephaga (Coleoptera) Rolf G. Beutela,Ã, Ignacio Riberab, Olaf R.P. Bininda-Emondsa aInstitut fu¨r Spezielle Zoologie und Evolutionsbiologie, FSU Jena, Germany bMuseo Nacional de Ciencias Naturales, Madrid, Spain Received 14 October 2005; accepted 17 May 2006 Abstract A supertree for Adephaga was reconstructed based on 43 independent source trees – including cladograms based on Hennigian and numerical cladistic analyses of morphological and molecular data – and on a backbone taxonomy. To overcome problems associated with both the size of the group and the comparative paucity of available information, our analysis was made at the genus level (requiring synonymizing taxa at different levels across the trees) and used Safe Taxonomic Reduction to remove especially poorly known species. The final supertree contained 401 genera, making it the most comprehensive phylogenetic estimate yet published for the group. Interrelationships among the families are well resolved. Gyrinidae constitute the basal sister group, Haliplidae appear as the sister taxon of Geadephaga+ Dytiscoidea, Noteridae are the sister group of the remaining Dytiscoidea, Amphizoidae and Aspidytidae are sister groups, and Hygrobiidae forms a clade with Dytiscidae. Resolution within the species-rich Dytiscidae is generally high, but some relations remain unclear. Trachypachidae are the sister group of Carabidae (including Rhysodidae), in contrast to a proposed sister-group relationship between Trachypachidae and Dytiscoidea. Carabidae are only monophyletic with the inclusion of a non-monophyletic Rhysodidae, but resolution within this megadiverse group is generally low. Non-monophyly of Rhysodidae is extremely unlikely from a morphological point of view, and this group remains the greatest enigma in adephagan systematics.

  • Land Management Practices Interactively Affect Wetland Beetle Ecological and Phylogenetic Community Structure
    Ecological Applications, 25(4), 2015, pp. 891–900 Ó 2015 by the Ecological Society of America Land management practices interactively affect wetland beetle ecological and phylogenetic community structure 1 SANDOR L. KELLY,HOJUN SONG, AND DAVID G. JENKINS Department of Biology, University of Central Florida, Orlando, Florida 32792 USA Abstract. Management practices can disturb ecological communities in grazing lands, which represent one-quarter of land surface. But three knowledge gaps exist regarding disturbances: disturbances potentially interact but are most often studied singly; experiments with multiple ecosystems as treatment units are rare; and relatively new metrics of phylogenetic community structure have not been widely applied. We addressed all three of these needs with a factorial experiment; 40 seasonal wetlands embedded in a Florida ranch were treated with pasture intensification, cattle exclosure, and prescribed fire. Treatment responses were evaluated through four years for aquatic beetle (Coleoptera: Adephaga) assemblages using classic ecological metrics (species richness, diversity) and phylogenetic community structure (PCS) metrics. Adephagan assemblages consisted of 23 genera representing three families in a well-resolved phylogeny. Prescribed fire significantly reduced diversity one year post-fire, followed by a delayed pasture 3 fire interaction. Cattle exclosure significantly reduced one PCS metric after one year and a delayed pasture 3 fence 3 fire interaction was detected with another PCS metric. Overall, effects of long-term pasture intensification were modified by cattle exclosure and prescribed fire. Also, PCS metrics revealed effects otherwise undetected by classic ecological metrics. Management strategies (e.g., ‘‘flash grazing,’’ prescribed fires) in seasonal wetlands may successfully balance economic gains from high forage quality with ecological benefits of high wetland diversity in otherwise simplified grazing lands.

Brigham, Lawrence M. Page, John D. Unzicker Mark J. Wetzel, Warren U. Brigham, Donald W. Webb, and Liane Suloway INTRODUCTION Aquatic macroinvertebrates are primary and secondary level consumers that play an important role in transferring energy through the different trophic levels of the food chains of aquatic ecosystems. These animals feed upon submerged and emergent macrophytes, plankton, and organic material suspended in the water column. Burrowing and feeding activities aid in the decomposition of plant and animal matter and the eventual recycling of nutrients. In addition, these organisms prey upon each other and serve as food for fishes, certain birds, and other animals. In general, aquatic macroinvertebrates have not been systematically surveyed in Illinois, and rarely have individual species been studied ecologically. This is due, in part, to the inconspicuous nature of most freshwater inverte- brates and the many taxonomic problems which preclude distributional, ecologi- cal, and other studies.

  • Adult Nepidae of Florida
    Graduate Student Project – Insect Classification – ENY 6166 University of Florida - Kendra Pesko - December 8, 2004 Adult Nepidae of Florida The family Nepidae, common name “waterscorpions”, is an aquatic insect family in the order Hemiptera (suborder Heteroptera). Of 13 species and three genera known throughout the United States and Canada, only five species in one genus (Ranatra) occur in Florida. Ranatra species are found in aquatic vegetation and debris, and can be collected by sweeping an aquatic net through vegetation along the edges of lakes. They will cling to emergent vegetation such as cattails to hide during the day, and return to the water surface at night. Ranatra species also make night time flights in order to colonize new areas, and will often end up on car windshields, which they may mistake for open water. Nepidae are unique among water bugs in possessing a stridulatory mechanism which consists of serrations on their fore-coxal cavity that contact coarse ridges which appear to be sclerotized setae. Both nymphs and adults of Ranatra possess these structures.

  • The Morphological Evolution of the Adephaga (Coleoptera)
    Systematic Entomology (2019), DOI: 10.1111/syen.12403 The morphological evolution of the Adephaga (Coleoptera) ROLF GEORG BEUTEL1, IGNACIO RIBERA2 ,MARTIN FIKÁCEˇ K 3, ALEXANDROS VASILIKOPOULOS4, BERNHARD MISOF4 andMICHAEL BALKE5 1Institut für Zoologie und Evolutionsforschung, FSU Jena, Jena, Germany, 2Institut de Biología Evolutiva, CSIC-Universitat Pompeu Fabra, Barcelona, Spain, 3Department of Zoology, National Museum, Praha 9, Department of Zoology, Faculty of Science, Charles University, Praha 2, Czech Republic, 4Center for Molecular Biodiversity Research, Zoological Research Museum Alexander Koenig, Bonn, Germany and 5Zoologische Staatssammlung, Munich, Germany Abstract. The evolution of the coleopteran suborder Adephaga is discussed based on a robust phylogenetic background. Analyses of morphological characters yield results nearly identical to recent molecular phylogenies, with the highly specialized Gyrinidae placed as sister to the remaining families, which form two large, reciprocally monophyletic subunits, the aquatic Haliplidae + Dytiscoidea (Meruidae, Noteridae, Aspidytidae, Amphizoidae, Hygrobiidae, Dytiscidae) on one hand, and the terrestrial Geadephaga (Trachypachidae + Carabidae) on the other. The ancestral habitat of Adephaga, either terrestrial or aquatic, remains ambiguous. The former option would imply two or three independent invasions of aquatic habitats, with very different structural adaptations in larvae of Gyrinidae, Haliplidae and Dytiscoidea. Introduction dedicated to their taxonomy (examples for comprehensive studies are Sharp, 1882; Guignot, 1931–1933; Balfour-Browne Adephaga, the second largest suborder of the megadiverse & Balfour-Browne, 1940; Jeannel, 1941–1942; Brinck, 1955, > Coleoptera, presently comprises 45 000 described species. Lindroth, 1961–1969; Franciscolo, 1979) and morphology. The terrestrial Carabidae are one of the largest beetle families, An outstanding contribution is the monograph on Dytiscus comprising almost 90% of the extant adephagan diversity.
