  • Insect Survey of Four Longleaf Pine Preserves
    A SURVEY OF THE MOTHS, BUTTERFLIES, AND GRASSHOPPERS OF FOUR NATURE CONSERVANCY PRESERVES IN SOUTHEASTERN NORTH CAROLINA Stephen P. Hall and Dale F. Schweitzer November 15, 1993 ABSTRACT Moths, butterflies, and grasshoppers were surveyed within four longleaf pine preserves owned by the North Carolina Nature Conservancy during the growing season of 1991 and 1992. Over 7,000 specimens (either collected or seen in the field) were identified, representing 512 different species and 28 families. Forty-one of these we consider to be distinctive of the two fire- maintained communities principally under investigation, the longleaf pine savannas and flatwoods. An additional 14 species we consider distinctive of the pocosins that occur in close association with the savannas and flatwoods. Twenty nine species appear to be rare enough to be included on the list of elements monitored by the North Carolina Natural Heritage Program (eight others in this category have been reported from one of these sites, the Green Swamp, but were not observed in this study). Two of the moths collected, Spartiniphaga carterae and Agrotis buchholzi, are currently candidates for federal listing as Threatened or Endangered species. Another species, Hemipachnobia s. subporphyrea, appears to be endemic to North Carolina and should also be considered for federal candidate status. With few exceptions, even the species that seem to be most closely associated with savannas and flatwoods show few direct defenses against fire, the primary force responsible for maintaining these communities. Instead, the majority of these insects probably survive within this region due to their ability to rapidly re-colonize recently burned areas from small, well-dispersed refugia.

  • F. Christian Thompson Neal L. Evenhuis and Curtis W. Sabrosky Bibliography of the Family-Group Names of Diptera
    F. Christian Thompson Neal L. Evenhuis and Curtis W. Sabrosky Bibliography of the Family-Group Names of Diptera Bibliography Thompson, F. C, Evenhuis, N. L. & Sabrosky, C. W. The following bibliography gives full references to 2,982 works cited in the catalog as well as additional ones cited within the bibliography. A concerted effort was made to examine as many of the cited references as possible in order to ensure accurate citation of authorship, date, title, and pagination. References are listed alphabetically by author and chronologically for multiple articles with the same authorship. In cases where more than one article was published by an author(s) in a particular year, a suffix letter follows the year (letters are listed alphabetically according to publication chronology). Authors' names: Names of authors are cited in the bibliography the same as they are in the text for proper association of literature citations with entries in the catalog. Because of the differing treatments of names, especially those containing articles such as "de," "del," "van," "Le," etc., these names are cross-indexed in the bibliography under the various ways in which they may be treated elsewhere. For Russian and other names in Cyrillic and other non-Latin character sets, we follow the spelling used by the authors themselves. Dates of publication: Dating of these works was obtained through various methods in order to obtain as accurate a date of publication as possible for purposes of priority in nomenclature. Dates found in the original works or by outside evidence are placed in brackets after the literature citation.

Copyright © 2004 Cambridge University Press DOI: 10.1017/S0266467404001725 Printed in the United Kingdom General herbivore outbreak following an El Nino-related˜ drought in a lowland Panamanian forest Sunshine A. Van Bael∗†, Annette Aiello∗, Anayansi Valderrama∗, Enrique Medianero∗, Mirna Samaniego∗ and S. Joseph Wright∗ ∗Smithsonian Tropical Research Institute, Box 2072, Balboa, Republic of Panama †Department of Animal Biology, University of Illinois, Urbana, IL 61801, USA (Accepted 10 February 2004) Abstract: A severe outbreak of Lepidoptera followed the 1997–98 El Nino˜ Southern Oscillation event, during which the climate in central Panama was unusually dry. The outbreak involved the larvae of at least 12 species of Lepidoptera and occurred at a seasonally dry, deciduous forest site, where extensive background data were available regarding climate, tree species and non-outbreak herbivory levels. Most Lepidoptera were associated with only one or two larval host plant species belonging to the same family, and the majority were monophagous during this study. During the outbreak, caterpillar densities for the major outbreak species averaged 1.6 larvae per young leaf and 0.18 larvae per leaf for leaves of all ages. For canopy trees and lianas, the mean level of leaf damage was 13.8%, ranging from 1–100%. Seven out of 20 tree species sustained most of the damage, with 21–37% of the leaf area consumed. Relative to non-outbreak years, damage levels increased by more than 250% during the outbreak. Single-species outbreaks were observed in other areas with a similar drought, but wetter forests in central Panama did not experience outbreaks during this period.

    Busey Woods Bioblitz Report of Scientific Findings Submitted to: Kathy Barker Illinois Department of Natural Resources December 1, 2006 by Derek A. Liebert Urbana Park District Natural Areas Coordinator The results and findings of the Busey Wood Bioblitz were entered into the Illinois Natural History Survey (INHS) Mandela database under the oversight of database creator Gail Kampmeier. After UPD staff and volunteers spent much time verifying the authenticity of identifications and working with Kampmeier to make updates to the taxonomy of the new species identified and added to Mandela database, the final species count for the Bioblitz totaled 1327 species. The attached Mandela generated report shows the breakdown and distribution of species according to Kingdom and Major Groups. Among these, scientists discovered 738 invertebrates (611 insects), 378 higher plants, 62 fungi, 54 birds, 30 fish, 13 mammals, and 4 amphibians. It is notable that invertebrates accounted for over ½ of all species identified with higher plants adding considerably to that total. Such results are in keeping with the pyramidal trophic distribution of species fundamental to the ecological sciences. Kampmeier’s attached report draws some additionally interesting comparisons between the findings of the Busey Woods blitz of 2005 and that of the Allerton Bioblitz of 2001, in which although just a fraction of Allerton in size, Busey Woods provided similar results across many of the major groups. Beyond Kampmeier’s comparisons, the results from such a study offer many opportunities for the UPD’s environmental education staff to communicate and generate enthusiasm among its residents for the diversity of organisms that are present in a relatively small woodland—right in their own backyards.
