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.

  • 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.

  • Meso-Mammal Cave Use and North American Porcupine
    MESO-MAMMAL CAVE USE AND NORTH AMERICAN PORCUPINE HABITAT USE IN CENTRAL TEXAS A Dissertation by ANDREA ELISA MONTALVO Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Roel R. Lopez Committee Members, Nova J. Silvy Susan M. Cooper Rusty A. Feagin Head of Department, Michael P. Masser May 2017 Major Subject: Wildlife and Fisheries Sciences Copyright 2017 Andrea Elisa Montalvo ABSTRACT Meso-mammals are frequent cave visitors whose role in cave ecology is poorly understood. Understanding meso-mammal cave use is essential because caves are often managed for United States federally endangered, cave-obligate arthropods. My objectives for this study were to quantify annual meso-mammal cave visitation, determine behaviors of meso-mammals while in the caves, to develop multinomial regression to determine which variables best differentiate caves use by each species, and to determine how North American porcupines incorporate caves into their home range and habitat use. North American porcupines (Erethizon dorsatum) were the most common cave visitor (64%), followed by raccoons (Procyon lotor; 14%) and Virginia opossums (Didelphis virginiana; 10%). These results are noteworthy because central Texas caves were historically associated with raccoons and the additional nutrient inputs of North American porcupines could facilitate replacement of cave-obligate species by more competitive, or predatory, terrestrial species. Videos recorded in cave passages showed North American porcupines used caves for denning and grooming, while Virginia opossums used caves for feeding. The strongest multinomial model showed that, compared to North American porcupine, raccoons and Virginia opossums had greater odds of using caves with gates (2.36, 4.10, respectively) and pit entrances (6.11, 2.23, respectively).

ALLISON & ASSOCIATES FINAL SOUTHERN EDWARDS PLATEAU HABITAT CONSERVATION PLAN BOWMAN © 2015 PROJECT NO. 005520-01-001 EXECUTIVE SUMMARY WHAT IS THE SOUTHERN EDWARDS PLATEAU HABITAT CONSERVATION PLAN? The Southern Edwards Plateau Habitat Conservation Plan (“SEP-HCP” or the “Plan”) is a way for Bexar County and the City of San Antonio (the “Permittees”) to assist with compliance of the Endangered Species Act. These compliance issues threaten the economic growth of the greater San Antonio region. The purposes of the SEP-HCP are to: (1) Promote regional conservation; (2) Provide support for Camp Bullis; (3) Involve local stakeholders in conservation planning; (4) Streamline endangered species permitting; (5) Implement locally appropriate and cost-effective permitting and conservation strategies; and (6) Leverage available resources. Upon approval of the SEP-HCP by the U.S. Fish and Wildlife Service (the “Service”), a 30-year Incidental Take Permit (ITP) under section 10(a)(1)(B) of the Endangered Species Act (“ESA”) would be issued. The Permit would authorize a limited amount of “incidental taking” of nine federally listed endangered species (the “Covered Species”) within the jurisdictions of Bexar County and the City of San Antonio. In return, the SEP-HCP will promote the conservation of the Covered Species and related natural resources in Bexar County and other counties of the Southern Edwards Plateau.

See Table 1 for a list of endangered karst invertebrates (53 FR 36029-36033; 65 FR 81419-81433) in these three counties. Section 10(a)(1)(A) permits, also referred to as recovery, enhancement of survival, or scientific permits, allow for “take” of listed species that may or will occur while conducting research to further the recovery of a listed species (see When a Section 10(a)(1)(A) Scientific Permit is Needed below). This document outlines methods to be used, information to be included in final reports, and minimum qualifications for personnel conducting presence/absence surveys for endangered karst invertebrates under a section 10(a)(1)(A) permit. The objective of this document is to identify survey methods that will produce sound scientific information upon which to base decisions and actions for the conservation of these endangered species. Using consistent survey methodology will also allow for greater comparison and analysis of results, and thereby increase our understanding of these species and their habitat requirements.

Using both new and published data from 1801 individuals belonging to 361 morphospecies, this study examined intra- and interspecifi c divergences for 19 genera that were each represented by at least 10 morphospecies. We particularly focused on increasing species-level sampling in order to better characterize levels of interspecifi c divergence within species-rich genera and to examine the prevalence of a “barcode gap” (discontinuity between intra- and interspecifi c di- vergences).
