  • Desert Aquatic Ecosystems and the Genetic and Morphological Diversity of Death Valley System Speckled Dace
    American Fisheries Society Symposium 17:350-359, 1995 © Copyright by the American Fisheries Society 1995 Desert Aquatic Ecosystems and the Genetic and Morphological Diversity of Death Valley System Speckled Dace DONALD W. SADA Environmental Studies Program, University of Nevada-Las Vegas 2689 Highland Drive, Bishop, California 93514, USA HUGH B. BRITTEN AND PETER F. BRUSSARD Biodiversity Research Center, Department of Biology, University of Nevada Reno, Nevada 89557-0015, USA Abstract.—The morphological and genetic diversities of fishes in North American deserts have been examined to estimate evolutionary rates, to create models of interbasin pluvial connectivity, and to justify protection of aquatic ecosystems throughout the region. Morphological and genetic studies comparing 13 populations of speckled dace Rhinichthys osculus from the Death Valley system, Lahontan basin, and lower Colorado River were conducted to quantify differences among populations. Differences in meristic and mensural characteristics among populations were highly significant, but differences in body shape were slight and best explained as representing two forms, one deep-bodied and short, the other elongate and slender. Starch gel electrophoretic assays of 23 loci showed isolated populations to be genetically unique. Fifty-nine taxa are identified as endemic to wetland and aquatic habitats in the Death Valley system: 16 forms of fish, 1 amphibian, 22 mollusks, 7 aquatic insects, 3 mammals, and 10 forms of flowering plants. Genetic and morphological differentiation of isolated speckled dace populations and the diversity and number of endemic forms associated with wetlands and aquatic habitats in the Death Valley system suggest that each desert wetland community functions as an evolutionarily significant unit.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • This BA Was Written in Accordance with The
    BIOLOGICAL ASSESSMENT, JOSEPH CREEK FOREST HEALTH PROJECT PROPOSED ACTION The Proposed Action involves the implementation of forest health improvement and fuels reduction activities on approximately 2,870 acres within the Joseph Creek Forest Health Project analysis area through the use of standard forest harvesting operations and prescribed burning treatments. The project is located approximately 11.5 miles northeast of the town of Alturas, California in Modoc County, California and occurs along the Warner Mountains on lands administered by the MDF Warner Mountain Ranger District (RD). The proposed treatments will occur in portions of Township 43 North, Range 14 East (T43N, R14E); T43N, R15E; T44N, R15E; and T45N, R14E, Mount Diablo Base and Meridian (treatment area). CE Name Acres Primary Objective Joseph Creek Forest Health 2870 acres Fuels Project Reduction CURRENT MANAGEMENT DIRECTION Managment for the Forest is detailed in the Modoc National Forest Land and Resource Management Plan (LRMP), Lost River and Shortnose Sucker Recovery Plan (1993), and other documents, which are referenced in the LRMP. THREATENED AND ENDANGERED SPECIES Three endangered species, Lost River sucker (Deltistes luxatus), shortnose sucker (Chasmistes brevirostris) and Shasta crayfish (Pacifastacus fortis), and one threatened species, the Warner sucker (Catostomus warnerensis) occur on or downstream of the Modoc National Forest. Lost River sucker and shortnose sucker – The Lost River sucker and shortnose sucker are endemic to the upper Klamath Basin which includes the Upper Klamath River, Oregon/California and the Lost River system in north-central California and south/central Oregon. These species are found within the Lost River drainage on Devil's Garden and Doublehead Districts; these fish are known to be widespread in Willow, Boles, and Fletcher Creeks as well as in pools and wetlands.

    Pacifastacus leniusculus Dana, 1852 Pacifastacus leniusculus is a large, hardy The signal crayfish cool-temperate freshwater crayfish that occupies a wide range of habitats from small streams to large rivers and natural lakes, including sub-alpine lakes. It also grows well in culture ponds and is tolerant of brackish water and high temperatures. The signal crayfish is endemic to the northwestern United States and southwestern Canada, from where it was introduced into the more southerly states. It has also been introduced to Europe and Japan as part of the livefood trade and for aquaculture purposes. The signal crayfish is an aggressive competitor and has been responsiblePacifastacus for displacing nigrescens indigenous crayfish species wherever it has been introduced. The ‘Critically Endangered (CR)’ SootyP. leniusculuscrayfish ( ) native to the western USA has become extinct partly due to interspecific competition with ; the signal crayfishPacifastacus has also fortis been implicated in causing P.a reductionleniusculus in the range of the endemic ‘Critically Endangered (CR)’ Shasta crayfish ( ) (Taylor, 2002).Cambaroides Photo credit: Wikimedia Commons (User: White Knight) japonicus was introduced into Japan from Portland, Oregon, where it has reduced the range of the endemic Aphanomyces astaci on the island of Hokkaido (Kawai & Hiruta, 1999).

  • A Preliminary Survey of the Aquatic and Semiaquatic Hemiptera
    Polhemus and Polhemus: Aquatic Hemiptera of Desert Hot Springs 1 A preliminary survey of the aquatic and semiaquatic Hemiptera occurring in the springs of the Railroad Valley, White River, and Amargosa River drainage systems, Nevada and California, with special reference to thermal relicts Dan A. Polhemus Dept. of Entomology, Bishop Museum, P. 0. Box 19000-A, Honolulu, HI 96817 ard John T. Polhemus Univ. of Colorado Museum, 3115 S. York St., Englewood, CO 80110 INTRODUCTION One of the most remarkable concentrations of disjunct and endemic aquatic Hemiptera in North America is found in the thermal refugia of the Railroad Valley, White River, and Amargosa River drainages of Nevada and California. These drainages represent former tributaries to the Colorado system that were continuous systems in the Pliocene and Pleistocene, but have been subsequently dessicated and reduced to discontinous spring fed aquatic refugia. The thermal springs of these three systems contain a large number of endemic aquatic Hemiptera species, as well as many highly disjunct populations of other taxa. The current report details the distributions of these species, addresses certain taxonomic problems relating to them, and considers the biogeographic significance of this thermally relictual fauna. LOCALITIES SAMPLED The information upon which this report is based has been collected by the authors over a period of thirty years, and in many cases the passage of several decades has seen a serious degredation of the aquatic habita~s listed below. For this reason an attempt has been made in the last three years to revisit many of the most critical habitats and &scertain the status of their aquatic Hemiptera faunas.

We used historical sources, morphology-based taxonomy and mtDNA sequence data to address questions about the signal crayfish Pacifastacus leniusculus. These included evaluating unrecogn- ised cryptic diversity and investigating the extent to which P. leniusculus may have been introduced within its presumed native range in the Pacific Northwest region of North America. Our study builds and expands on Pacific Northwest phylogeographic knowledge, particularly related to patterns of glacial refugia for freshwater species. 2. Extensive collections (824 specimens) from British Columbia (Canada), Idaho, Nevada, Oregon and Washington (United States) were used to characterise P. leniusculus at the mitochondrial 16S rRNA gene. Genetic groups within the species were elucidated by phylogenetics and AMOVAAMOVA; evolutionary relationships within the most common and diverse group were investigated using a statistical parsimony haplotype network, a nested AMOVA, and tests of isolation by distance.
