An Abstract of The Short-term Impacts of Land Management Techniques on Prairie Ant Communities by Russell L. Friedrich Submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of Master of Science in Biology (Ecology track) The University of Toledo May 2010 Controlled burning and mowing are among the most common forms of disturbance in prairie grasslands. Extensive studies on vegetative responses to fire, grazing, and mowing have been investigated, however, there is a lack of information on how animals and particularly insects are affected by these disturbances. Ants in particular play vital ecological roles in nutrient cycling, soil structure and turnover, predation, and seed dispersal, but few studies have assessed ant response to land management practices in prairie ecosystems. This research will assess the short-term impacts of controlled burning and mowing on ant communities. Ants were sampled in 17 prairie sites, divided into three treatments (burn, control, mow) within the Oak Openings Region in Ohio.

  • Arthropods of Elm Fork Preserve

    Arthropods of Elm Fork Preserve

    Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.

    Pyramid Ants Dorymyrmex bureni Dorymrymex medeis Contributor: Timothy S. Davis DESCRIPTION Taxonomy and Basic Description Pyramid Ants are easily identified in the field by their distinctive cone shaped mounds with an entrance hole in the center. In South Carolina, two species have been collected and identified. Taxonomically, the Pyramid ants are in the subfamily Dolichoderinae. The Dolichoderine ants are distinguished as having a single “hump” or node between the thorax and gaster and the absence of a stinger. The genus Dorymyrmex is distinguished by the presence of a distinct mid- dorsal cone shaped protuberance. It should be noted that over the years the genus name has shifted from Doyrmyrmex to Conomyrma, back to Dorymyrmex. Hence, some papers from the mid 1980’s will bear the Conomyrma name. The best treatment of the Photo by T.S. Davis identification of the pyramid ants in the Southeastern United States currently is a paper by James Trager published in 1988. While color is rarely a good character for identifying ants, this character works well with pyramid ants. D. bureni is a light red to yellowish ant. D. medee is dark brown almost black in color. Another important character is the shape of the mesonotum. In D. bureni the mesonotum is smooth with out a sharp angle. D. medee the mesonotum is bears a sharp angle. There are nearly 9,000 species of ants that have been described on a world-wide basis. As would be expected, the biology and life histories of these ants are nearly as diverse as the group itself. Understanding the biology and life history of a given species is critical to decisions made regarding the management and/or conservation of an ant species.

    GENERAL HOUSEHOLD PESTS Ants Are Some of the Most Ubiquitous Insects Found in Community Environments. They Thrive Indoors and O

    GENERAL HOUSEHOLD PESTS Ants are some of the most ubiquitous insects found in community environments. They thrive indoors and outdoors, wherever they have access to food and water. Ants outdoors are mostly beneficial, as they act as scavengers and decomposers of organic matter, predators of small insects and seed dispersers of certain plants. However, they can protect and encourage honeydew-producing insects such as mealy bugs, aphids and scales that are feed on landscape or indoor plants, and this often leads to increase in numbers of these pests. A well-known feature of ants is their sociality, which is also found in many of their close relatives within the order Hymenoptera, such as bees and wasps. Ant colonies vary widely with the species, and may consist of less than 100 individuals in small concealed spaces, to millions of individuals in large mounds that cover several square feet in area. Functions within the colony are carried out by specific groups of adult individuals called ‘castes’. Most ant colonies have fertile males called “drones”, one or more fertile females called “queens” and large numbers of sterile, wingless females which function as “workers”. Many ant species exhibit polymorphism, which is the existence of individuals with different appearances (sizes) and functions within the same caste. For example, the worker caste may include “major” and “minor” workers with distinct functions, and “soldiers” that are specially equipped with larger mandibles for defense. Almost all functions in the colony apart from reproduction, such as gathering food, feeding and caring for larvae, defending the colony, building and maintaining nesting areas, are performed by the workers.

Case Department of Biology 0116, University of California at San Diego, La Jolla, CA 92093-0116, USA; ∗Author for correspondence (e-mail: [email protected]; fax: +1-619-534-7108) Received 9 June 1998; accepted in revised form 22 February 1999 Key words: Argentine ant, biological invasions, competition, invasive ants, Linepithema humile, microsatellites, nestmate recognition, population bottleneck, unicoloniality Abstract In this paper, we examine the hypothesis that reduced intraspecific aggression underlies the competitive prowess of Argentine ants in their introduced range. Specifically, we test three predictions of this hypothesis by comparing the genetic diversity, behavior, and ecology of Argentine ants in their native range to introduced populations. Differences between native and introduced populations of Argentine ants were consistent with our predictions. Introduced populations of the Argentine ant appear to have experienced a population bottleneck at the time of introduction, as evidenced by much reduced variation in polymorphic microsatellite DNA markers. Intraspecific aggression was rare in introduced populations but was common in native populations. Finally, in contrast to the Argentine ant’s ecological dominance throughout its introduced range, it did not appear dominant in the native ant assemblages studied in Argentina. Together these results identify a possible mechanism for the widespread success of the Argentine ant in its introduced range. Introduction Studies that compare the ecology of invasive species between their introduced and native ranges can be par- Despite the widespread problems associated with bio- ticularly insightful.
