Thank you for participating in what promises to be another fantastic forum of learning. Whether you attend paper presentations or poster sessions you will be certain to find highly informative topics from among the 267 papers and posters on the agenda today, ranging from Anthropology to Zoology. As I hope to do, consider attending a presentation or reading a poster that is out of your particular scientific discipline. It’s a great way to see how diverse and interesting our Academy really is. Regardless of whether you have or have not in the past, please consider giving a paper or presenting a poster next year - and continue to do so in the future. This is my 34th year as a member of the IAS and except for my absence to attend a family member’s funeral I have attended every annual meeting since joining the organization in 1982. I have also presented a paper in every one of those meetings. I don’t know if this is a record, but if it is, I would like to challenge every one of you to beat it! The Academy is particularly thrilled this morning to welcome remarks from the 51st Lieutenant Governor of Indiana Eric Holcomb. A life-long Hoosier, Lieutenant Governor Holcomb is a veteran of the United States Navy, was a trusted advisor to both Governor Mitch Daniels and Senator Dan Coats, and was nominated to serve by Governor Mike Pence on March 2, 2016, and confirmed by the General Assembly and sworn into office on March 3, 2016. We are also particularly thrilled to have Conservation Attorney William “Bill” Weeks as our 131st Annual Academy Meeting Luncheon Speaker this afternoon. Bill and I have been collaborators and friends for many years, beginning with when he took the helm as Director of the Indiana Chapter of The Nature Conservancy. Dr. Weeks serves as professor and director of the Conservation Law Center at the Maurer School of Law at Indiana University. He has been exemplary in combining his legal skills and passion for nature. He will be speaking to us today on the topic of ‘The Evolution of Conservation Thought and Strategy.’ In addition to the tremendous breadth of research presented today, we are very happy to welcome experts who will be presenting the Workshop and the ‘Hot Topic’ discussions. The ‘Hot Topics’ and Workshop are timely, and span the range of science interests. I am sure there are several of them that will capture your attention today. At today's luncheon, the Indiana Academy of Science will honor members who have demonstrated exemplary records of accomplishment. Such honors have been conferred on members since the late 1930's. The Academy will induct as Fellow of the Academy Dr. Dale Edwards, Dr. James O. Farlow, Dr. Michael S. Finkler and Kay Yatskievych, as well as bestow its Distinguished Scholar Award on Dr. James O. Farlow, and its Distinguished Service award on Dr. K. Michael Foos. Our sponsors this year are those who have supported the work of the Indiana Academy of Science through sponsorship of the Annual Academy Meeting for several years now. We are truly grateful to the W.K. Kellogg Foundation, Eli Lilly and Company Foundation, Subaru of America (Columbus Central Zone), and White River State Park. I also wish to thank the J. W. Marriott of Indianapolis for hosting the 131st Annual Academy Meeting and the Indiana State Museum for their continued support of the mission of the Academy.

S. Fish and Wildlife Service Indiana Comprehensive Wildlife Strategy 2 Indiana Comprehensive Wildlife Strategy 3 Indiana Comprehensive Wildlife Strategy 4 II. Executive Summary The Indiana Department of Natural Resources, Division of Fish and Wildlife (DFW) working with conservation partners across the state, developed a Comprehensive Wildlife Strategy (CWS) to protect and conserve habitats and associated wildlife at a landscape scale. Taking advantage of Congressional guidance and nationwide synergy Congress recognized the importance of partnerships and integrated conservation efforts, and charged each state and territory across the country to develop similar strategies. To facilitate future comparisons and cross-boundary cooperation, Congress required all 50 states and 6 U.S. territories to simultaneously address eight specific elements. Congress also directed that the strategies must identify and be focused on the “species in greatest need of conservation,” yet address the “full array of wildlife” and wildlife-related issues. Throughout the process, federal agencies and national organizations facilitated a fruitful ongoing discussion about how states across the country were addressing wildlife conservation. States were given latitude to develop strategies to best meet their particular needs. Congress gave each state the option of organizing its strategy by using a species-by-species approach or a habitat- based approach.

  • A REVIEW of the MAYFLY FAMILY METRETOPODIDAE' Some Years
    A REVIEW OF THE MAYFLY FAMILY METRETOPODIDAE' BY LEWIS BERNER 2 Department of Zoology University of Florida Some years ago, I collected nymphs of a species of Siphloplecton from the Withlacoochee River near Valdosta, Georgia, from which I was able to rear adults. As I worked with them, it appeared that they were Siphloplecton basale (Walker), but further study .con­ vinced me that they represented a new species. Dr. W. L. Peters, collecting in northwestern Florida, also reared adults, which at first inspection seemed to be S. basale, but he, too, concluded that his specimens represented a new species and he asked that I add his col­ lections to mine. As I attempted to understand the relationships of these two new forms to species earlier described, I realized that it would be well to review the entire genus. Among the specimens loaned to me for study by Dr. G. F. Edmunds, Jr., I found a collec­ tion of nymphs from Alaska which had been identified as Siphloplecton. It soon became apparent to me that they had been misidentified, but the similarities of the nymphs to those of Siphloplecton were so great that the misidentification was no sur­ prise. The nymphs were those of Metretopus (probably borealis [Eaton]). I concluded that such close similarities required that I in­ clude a study of Metretopus along with my review of Siphloplec­ ton. My examination of the immatures of the two genera has revealed morphological characteristics that now permit ready separation. These differences are detailed below and are included in the key. The genus Siph/oplecton was erected by W.

  • Xylem Specialists Colonizing Texas Vineyards: Abundance and Distribution Studied Through Generalized Additive Models
    XYLEM SPECIALISTS COLONIZING TEXAS VINEYARDS: ABUNDANCE AND DISTRIBUTION STUDIED THROUGH GENERALIZED ADDITIVE MODELS Project Leaders: Cooperator: Forrest Mitchell Isabelle Lauzière Simon Sheather Texas Agricultural Experiment Station Texas Agricultural Experiment Station Department of Statistics Texas A&M University Texas A&M University Texas A&M University Stephenville, TX 76401 Fredericksburg, TX 78624 College Station, Texas 77843 Reporting Period: The results reported here are from work conducted April 2007 through October 2007. ABSTRACT Xylem specialists in the Hemiptera: Auchenorrhyncha feed on xylem fluid and exhibit therefore the potential for transmission of Xylella fastidiosa (Xf), the causal agent in Pierce’s disease of grapevine. An increasingly larger survey was initiated in Texas in 2003 and remains ongoing with 45 locations currently monitored. Over 25 insect species belonging in this group were collected from yellow sticky traps. Among these, two leafhoppers and one spittlebug, comprised over 90% of the xylem specialists caught. The glassy-winged sharpshooter Homalodisca vitripennis, the most commonly known vector of Pierce’s disease of grapevine in the U.S. is the most common and abundant insect captured across the state. Insect abundance varied significantly over seasons, and among locations. Residual populations were found overwintering near vineyards, but also in a variety of habitats including urban and vegetation found near natural sources of water. Generalized additive models which were originally developed to analyze complex population data were used with our Central Texas dataset as a tool to identify changes in the distribution of leafhopper and spittlebug species near vineyards. These models helped understanding insect distribution through time. INTRODUCTION Pierce’s disease of grapevine is one of the most important limiting factors to grape production in Texas.

    CHARACTERIZATION OF XYLELLA FASTIDIOSA STRAINS THAT CAUSE BACTERIAL LEAF SCORCH OF SOUTHERN HIGHBUSH BLUEBERRY (VACCINIUM CORYMBOSUM INTERSPECIFIC HYBRIDS), AND DETECTION OF THE PATHOGEN IN PLANTS AND GLASSY-WINGED SHARPSHOOTERS [HOMALODISCA VITRIPENNIS (GERMAR)] (HEMIPTERA: CICADELLIDAE) IN SOUTH GEORGIA by LORNA DENISE NISSEN (Under the Direction of Timothy P. Denny and Phillip M. Brannen) ABSTRACT Xylella fastidiosa is a genetically diverse species with a wide host range. This xylem- limited bacterium was recently proven to cause bacterial leaf scorch of blueberry (BLSB), a new disease of Georgia’s most economically important fruit crop. Since little is known about the strains of X. fastidiosa affecting southern highbush blueberry (Vaccinium corymbosum interspecific hybrids), the objectives of this research were to characterize BLSB strains and develop assays to detect them in plants and the most probable insect vector, the glassy-winged sharpshooter [Homalodisca vitripennis (Germar)] (Hemiptera: Cicadellidae). Published, redesigned and novel primer pairs were used with the polymerase chain reaction (PCR) to analyze genomic DNA derived from pure cultures and DNA extracts of plant and insect tissue. Methods were developed to reduce PCR inhibition that occurred in extracts. BLSB strains in Georgia were found to be most similar to Dixon, an A-type strain of X. fastidiosa that causes almond leaf scorch.

  • Arthropods Associated with Above-Ground Portions of the Invasive Tree, Melaleuca Quinquenervia, in South Florida, Usa
    300 Florida Entomologist 86(3) September 2003 ARTHROPODS ASSOCIATED WITH ABOVE-GROUND PORTIONS OF THE INVASIVE TREE, MELALEUCA QUINQUENERVIA, IN SOUTH FLORIDA, USA SHERYL L. COSTELLO, PAUL D. PRATT, MIN B. RAYAMAJHI AND TED D. CENTER USDA-ARS, Invasive Plant Research Laboratory, 3205 College Ave., Ft. Lauderdale, FL 33314 ABSTRACT Melaleuca quinquenervia (Cav.) S. T. Blake, the broad-leaved paperbark tree, has invaded ca. 202,000 ha in Florida, including portions of the Everglades National Park. We performed prerelease surveys in south Florida to determine if native or accidentally introduced arthro- pods exploit this invasive plant species and assess the potential for higher trophic levels to interfere with the establishment and success of future biological control agents. Herein we quantify the abundance of arthropods present on the above-ground portions of saplings and small M. quinquenervia trees at four sites. Only eight of the 328 arthropods collected were observed feeding on M. quinquenervia. Among the arthropods collected in the plants adven- tive range, 19 species are agricultural or horticultural pests. The high percentage of rare species (72.0%), presumed to be transient or merely resting on the foliage, and the paucity of species observed feeding on the weed, suggests that future biological control agents will face little if any competition from pre-existing plant-feeding arthropods. Key Words: Paperbark tree, arthropod abundance, Oxyops vitiosa, weed biological control RESUMEN Melaleuca quinquenervia (Cav.) S. T. Blake ha invadido ca. 202,000 ha en la Florida, inclu- yendo unas porciones del Parque Nacional de los Everglades. Nosotros realizamos sondeos preliminares en el sur de la Florida para determinar si los artópodos nativos o accidental- mente introducidos explotan esta especie de planta invasora y evaluar el potencial de los ni- veles tróficos superiores para interferir con el establecimento y éxito de futuros agentes de control biológico.

  • Rapid Pest Risk Analysis (PRA) For: Summary And
    Rapid Pest Risk Analysis (PRA) for: Xylella fastidiosa February 2020 (update of 2014 UK PRA and 2017 climate appendix) Summary and conclusions of the rapid PRA This rapid PRA shows: Xylella fastidiosa is a plant-pathogenic bacterium which infects a very wide range of plants. It is already heavily regulated to reduce the likelihood of it entering the UK. In some host species, impacts can be severe and the plant or tree can be killed rapidly. Other hosts have latent infections, or may remain asymptomatic (but still be capable of spreading the disease) for several years before succumbing to the bacterium. Xylella fastidiosa is native to the Americas, but has been spread to countries elsewhere in the world, including parts of Europe. There are several subspecies of X. fastidiosa, which have different host ranges. Xylella fastidiosa is vectored by a number of xylem-feeding hemipteran insect species, including some which are widespread in the UK. At least parts of the UK are likely to prove suitable for X. fastidiosa to establish, but it is unclear what levels of damage it may be able to cause to plants in the UK. If an outbreak were to occur in the UK, the greatest impacts are expected to be social (though the assessment of potential social impacts is made with medium confidence, while confidence in potential economic and environmental impacts is low, indicating the uncertainty about the magnitude of direct impacts which might occur in the UK). Leaf scorches and other symptoms could be visible on amenity trees causing public concern, impacts on horticultural businesses could be severe, and this is already a 1 high-profile pest in the media.
