Plans are published by the U.S. Fish and Wildlife Service (Service), but are sometimes prepared with the assistance of recovery teams, contractors, state agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans are guidance and planning documents only. Identification of an action to be implemented by any private or public party does not create a legal obligation beyond existing legal requirements. Nothing in this plan should be construed as a commitment or requirement that any Federal agency obligate or pay funds in contravention of the Anti-Deficiency Act (U.S.C. 1341) or any other law or regulation. Recovery plans do not necessarily represent the views or the official positions or approval of any individuals or agencies involved in the plan formulation, other than the Service. They represent the official position of the Service only after the plan has been signed by the Regional Director as approved.

    Bennett, R. G. 1985. The natural history and taxonomy of Cicurina bryantae Exline (Araneae, Agelen- idae). J. Arachnol ., 13 :87-96 . THE NATURAL HISTORY AND TAXONOMY O F CICURINA BRYANTAE EXLINE (ARANEAE, AGELENIDAE ) R. G. Bennett Department of Biolog y Western Carolina University Cullowhee, North Carolina 28723 ABSTRACT Since its description in 1936 Cicurina bryantae Exline has been rarely collected . The recen t discovery of the microhabitat preference of this spider has allowed the observation and collection o f substantial numbers of specimens . The following account is compiled from these data . The natural history of the species is discussed (including the interesting tubular retreat constructs inhabited by immatures and adults) . Both sexes are described and figured (the male for the first time) . INTRODUCTION In 1936 Harriet Exline described a new species in the genus Cicurina Menge, 1869 on the basis of female specimens collected at Newfound Gap on the Tennessee-North Caro- lina border in 1930 by Nathan Banks . She named the species bryantae in honor of Eliza- beth Bangs Bryant who was at that time working at the Museum of Comparative Zoology where the specimens were deposited . Since that date, Cicurina bryantae has rarely been collected, its behavior and life history have not been recorded, and the male has not been described . Chamberlin and Ivie (1940) redescribed the female and mentioned two more female s captured by Ivie in 1933 in East Tennessee . Apparently no other specimens were col- lected until 1972 when J. O. Howell found an undescribed Cicurina male in a pitfall trap set in Union County, Georgia .

  • Petition to Delist the Bone Cave Harvestman (Texella Reyesi) in Accordance with Section 4 of the Endangered Species Act of 1973
    Petition to delist the Bone Cave harvestman (Texella reyesi) in accordance with Section 4 of the Endangered Species Act of 1973 PETITION TO DELIST THE BONE CAVE HARVESTMAN (TEXELLA REYESI) IN ACCORDANCE WITH SECTION 4 OF THE ENDANGERED SPECIES ACT OF 1973 Petitioned By: John F. Yearwood Kathryn Heidemann Charles & Cheryl Shell Walter Sidney Shell Management Trust American Stewards of Liberty Steven W. Carothers June 02, 2014 This page intentionally left blank. EXECUTIVE SUMMARY The federally endangered Bone Cave harvestman (Texella reyesi) is a terrestrial karst invertebrate that occurs in caves and voids north of the Colorado River in Travis and Williamson counties, Texas. The U.S. Fish and Wildlife Service (USFWS) listed T. reyesi as endangered in 1988 on the basis of only five to six known localities that occurred in a rapidly developing area. Little was known about the species at the time, but the USFWS deemed listing was warranted to respond to immediate development threats. The current body of information on T. reyesi documents a much broader range of known localities than known at the time of listing and resilience to the human activities that USFWS deemed to be threats to the species. Status of the Species • An increase in known localities from five or six at the time of listing to 172 today. • Significant conservation is in place with at least 94 known localities (55 percent of the total known localities) currently protected in preserves, parks, or other open spaces. • Regulatory protections are afforded to most caves in Travis and Williamson counties via state laws and regulations and local ordinances.

  • Section IV – Guideline for the Texas Priority Species List
    Section IV – Guideline for the Texas Priority Species List Associated Tables The Texas Priority Species List……………..733 Introduction For many years the management and conservation of wildlife species has focused on the individual animal or population of interest. Many times, directing research and conservation plans toward individual species also benefits incidental species; sometimes entire ecosystems. Unfortunately, there are times when highly focused research and conservation of particular species can also harm peripheral species and their habitats. Management that is focused on entire habitats or communities would decrease the possibility of harming those incidental species or their habitats. A holistic management approach would potentially allow species within a community to take care of themselves (Savory 1988); however, the study of particular species of concern is still necessary due to the smaller scale at which individuals are studied. Until we understand all of the parts that make up the whole can we then focus more on the habitat management approach to conservation. Species Conservation In terms of species diversity, Texas is considered the second most diverse state in the Union. Texas has the highest number of bird and reptile taxon and is second in number of plants and mammals in the United States (NatureServe 2002). There have been over 600 species of bird that have been identified within the borders of Texas and 184 known species of mammal, including marine species that inhabit Texas’ coastal waters (Schmidly 2004). It is estimated that approximately 29,000 species of insect in Texas take up residence in every conceivable habitat, including rocky outcroppings, pitcher plant bogs, and on individual species of plants (Riley in publication).

  • Araneae (Spider) Photos
    Araneae (Spider) Photos Araneae (Spiders) About Information on: Spider Photos of Links to WWW Spiders Spiders of North America Relationships Spider Groups Spider Resources -- An Identification Manual About Spiders As in the other arachnid orders, appendage specialization is very important in the evolution of spiders. In spiders the five pairs of appendages of the prosoma (one of the two main body sections) that follow the chelicerae are the pedipalps followed by four pairs of walking legs. The pedipalps are modified to serve as mating organs by mature male spiders. These modifications are often very complicated and differences in their structure are important characteristics used by araneologists in the classification of spiders. Pedipalps in female spiders are structurally much simpler and are used for sensing, manipulating food and sometimes in locomotion. It is relatively easy to tell mature or nearly mature males from female spiders (at least in most groups) by looking at the pedipalps -- in females they look like functional but small legs while in males the ends tend to be enlarged, often greatly so. In young spiders these differences are not evident. There are also appendages on the opisthosoma (the rear body section, the one with no walking legs) the best known being the spinnerets. In the first spiders there were four pairs of spinnerets. Living spiders may have four e.g., (liphistiomorph spiders) or three pairs (e.g., mygalomorph and ecribellate araneomorphs) or three paris of spinnerets and a silk spinning plate called a cribellum (the earliest and many extant araneomorph spiders). Spinnerets' history as appendages is suggested in part by their being projections away from the opisthosoma and the fact that they may retain muscles for movement Much of the success of spiders traces directly to their extensive use of silk and poison.
