Brown August 2005 Major Subject: Wildlife and Fisheries Sciences iii ABSTRACT Vegetation Classification and the Efficacy of Plant Dominance-Based Classifications in Predicting the Occurrence of Plant and Animal Species. (August 2005) James Hugh Yantis, B.A., The University of Texas at Austin; M.S., Texas A&M University Chair of Advisory Committee: Dr. Nova J. Silvy One strategy for conserving biodiversity is to select large-area preserves that complement each other so the maximum number of species is conserved. Estimates of biodiversity and complementarity are needed for optimum selection of preserves. Comparisons are made in part by defining and mapping vegetation associations under the assumption that candidate areas with no associations in common likely have high complementarity. Conversely, areas with many associations in common have low complementarity. Vegetation associations are often distinguished on the basis of the dominant plant species. Associations with markedly different dominants (e.g., evergreen and deciduous trees) are expected to indicate high complementarity. In this study I evaluated the complementarity of an evergreen forest and a deciduous forest. I also evaluated a dichotomy of subsoil texture. I compared 6 groups of species: (1) woody plants (Dicotyledonae), (2) birds (Aves), (3) small mammals (Mammalia) plus herptiles (Amphibia) and (Reptilia), (4) beetles iv (Coleoptera), (5) ants (Formicidae) plus velvet ants (Mutillidae), and (6) spiders (Araneae). I made the comparisons using canonical correspondence analysis (CCA), redundancy analysis (RDA), logistic regression, and 3 indices of biodiversity. In this study the species of dominant tree was more strongly associated with the distribution of species than was soil texture. Dominant tree and soil texture used together greatly improved the association with the distribution of species. The association defined by the dominant evergreen tree was not different than the association defined by the dominant deciduous tree, based on the criteria that an association is defined as having a Jaccard similarity index between 0.25 and 0.5. Similarities >0.5, as in this case, are too similar to be an association and are termed a subassociation. Evergreen forests and deciduous forests do not necessarily have high complementarity. Different dominant plant species do not necessarily define different associations. Dominant plant species are not necessarily useful in defining associations or higher-level classifications. v DEDICATION This dissertation is dedicated to my loving wife, Shirley Beaman Hosea Yantis, who conducted every survey and procedure with me, slept in a hot or rain-soaked tent, arose at 0300 hr to do bird surveys, worked each day from well before daylight to well after dark, and, most importantly, picked the really big wolf spiders out of the pitfall traps when I was afraid to do it. vi ACKNOWLEDGMENTS I would like to thank those individuals who helped me with this study.

  • Untangling Taxonomy: a DNA Barcode Reference Library for Canadian Spiders
    Molecular Ecology Resources (2016) 16, 325–341 doi: 10.1111/1755-0998.12444 Untangling taxonomy: a DNA barcode reference library for Canadian spiders GERGIN A. BLAGOEV, JEREMY R. DEWAARD, SUJEEVAN RATNASINGHAM, STEPHANIE L. DEWAARD, LIUQIONG LU, JAMES ROBERTSON, ANGELA C. TELFER and PAUL D. N. HEBERT Biodiversity Institute of Ontario, University of Guelph, Guelph, ON, Canada Abstract Approximately 1460 species of spiders have been reported from Canada, 3% of the global fauna. This study provides a DNA barcode reference library for 1018 of these species based upon the analysis of more than 30 000 specimens. The sequence results show a clear barcode gap in most cases with a mean intraspecific divergence of 0.78% vs. a min- imum nearest-neighbour (NN) distance averaging 7.85%. The sequences were assigned to 1359 Barcode index num- bers (BINs) with 1344 of these BINs composed of specimens belonging to a single currently recognized species. There was a perfect correspondence between BIN membership and a known species in 795 cases, while another 197 species were assigned to two or more BINs (556 in total). A few other species (26) were involved in BIN merges or in a combination of merges and splits. There was only a weak relationship between the number of specimens analysed for a species and its BIN count. However, three species were clear outliers with their specimens being placed in 11– 22 BINs. Although all BIN splits need further study to clarify the taxonomic status of the entities involved, DNA bar- codes discriminated 98% of the 1018 species. The present survey conservatively revealed 16 species new to science, 52 species new to Canada and major range extensions for 426 species.

  • Coleoptera: Carabidae) Diversity
    VEGETATIVE COMMUNITIES AS INDICATORS OF GROUND BEETLE (COLEOPTERA: CARABIDAE) DIVERSITY BY ALAN D. YANAHAN THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2013 Urbana, Illinois Master’s Committee: Dr. Steven J. Taylor, Chair, Director of Research Adjunct Assistant Professor Sam W. Heads Associate Professor Andrew V. Suarez ABSTRACT Formally assessing biodiversity can be a daunting if not impossible task. Subsequently, specific taxa are often chosen as indicators of patterns of diversity as a whole. Mapping the locations of indicator taxa can inform conservation planning by identifying land units for management strategies. For this approach to be successful, though, land units must be effective spatial representations of the species assemblages present on the landscape. In this study, I determined whether land units classified by vegetative communities predicted the community structure of a diverse group of invertebrates—the ground beetles (Coleoptera: Carabidae). Specifically, that (1) land units of the same classification contained similar carabid species assemblages and that (2) differences in species structure were correlated with variation in land unit characteristics, including canopy and ground cover, vegetation structure, tree density, leaf litter depth, and soil moisture. The study site, the Braidwood Dunes and Savanna Nature Preserve in Will County, Illinois is a mosaic of differing land units. Beetles were sampled continuously via pitfall trapping across an entire active season from 2011–2012. Land unit characteristics were measured in July 2012. Nonmetric multidimensional scaling (NMDS) ordinated the land units by their carabid assemblages into five ecologically meaningful clusters: disturbed, marsh, prairie, restoration, and savanna.

    Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally.
