Bexar County Karst Invertebrates Draft Recovery Plan
Bexar County Karst Invertebrates Draft Recovery Plan March 2008 Bexar County Karst Invertebrates Draft Recovery Plan BEXAR COUNTY KARST INVERTEBRATES DRAFT RECOVERY PLAN Southwest Region U.S. Fish and Wildlife Service Albuquerque, New Mexico March 2008 Approved: ___DRAFT_______________________________________ Regional Director, Southwest Region Date U.S. Fish and Wildlife Service Concur: __DRAFT____________________________________________ Executive Director Date Texas Parks and Wildlife Department ii Bexar County Karst Invertebrates Draft Recovery Plan DISCLAIMER Recovery plans delineate reasonable actions that the best available science indicates are necessary to recover or protect listed species. 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. -
Pervasive Gene Flow Across Critical Habitat for Four Narrowly Endemic
Freshwater Biology (2016) doi:10.1111/fwb.12758 Pervasive gene flow across critical habitat for four narrowly endemic, sympatric taxa † † ‡ LAUREN K. LUCAS* , ZACHARIAH GOMPERT ,J.RANDYGIBSON , KATHERINE L. BELL*, § C. ALEX BUERKLE AND CHRIS C. NICE* *Department of Biology, Texas State University, San Marcos, TX, U.S.A. † Department of Biology, Utah State University, Logan, UT, U.S.A. ‡ U.S. Fish & Wildlife Service, San Marcos Aquatic Resources Center, San Marcos, TX, U.S.A. § Department of Botany, University of Wyoming, Laramie, WY, U.S.A. SUMMARY 1. We studied genetic variation in four endangered animal taxa in the largest freshwater spring complex in the southwestern U.S.A., Comal Springs (TX): Eurycea salamanders, Heterelmis riffle beetles, Stygobromus amphipods and Stygoparnus dryopid beetles. They inhabit a spring complex with nearly stable conditions, which is threatened by climate change and aquifer withdrawals. The four taxa vary in their habitat affinities and body sizes. 2. We used genotyping-by-sequencing to obtain hundreds to thousands of genetic markers to accurately infer the demographic history of the taxa. We used approximate Bayesian computation to test models of gene flow and compare the results among taxa. We also looked for evidence that would suggest local adaptation within the spring complex. 3. An island model (equal gene flow among all subpopulations) was the most probable of the five models tested, and all four taxa had high migration rate estimates. 4. Small numbers of single nucleotide polymorphisms (SNPs) in each taxon tested were associated with environmental conditions and provide some evidence for potential local adaptation to slightly variable conditions across habitat patches within Comal Springs. -

Bowles1 *, Cheryl B. Barr2 and Ruth Stanford3 Texas Parks and Wildlife Department, University of California, Berkeley, and United States Fish and Wildlife Service With 5 figures and 4 tables Ab tract: Habitat characteristics and seasonal distribution of the riffle beetles Herere/ mis comalensis and Microcylloepu pusillus were studied at Comal Springs, Texas, during 1993-1994, to aid in developing sound reconunendations for sustaining their natural popu1atioas. Comal Springs consists of four major spring cutlers and spring runs. The four spring-runs are dissimilar in size, appearance, canopy and riparian cover, substrate composition, and aquatic macrophyte composition. Habitat conditions associated with the respective popuJatioos of riffle beetles, including physical-chemi cal measurements, water depth, and currenc velocity, were relatively unifom1 and var ied lHUe among sampling dates and spring-runs. However, the locations of the beetles in the respective spri ng-runs were not well correlated to current velocity, water depth, or distance from primary spring orifices. Factors such as substrate size and availability and competition are proposed as possibly influencing lheir respective distributions. Maintaining high-quality spring-flows and protection of Lhe physical habitat of Here· re/mis comalensis presently are the only means by which to ensure the survival of this endemic species. Key words: Conservation, habitat conditions, substrate availability, competition. 1 Authors' addresses: Texas Parks and Wildlife Department, 4200 Smith School Road, Austin, Texas 78744, USA. -

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). -
