  • Petition to List the Relict Leopard Frog (Rana Onca) As an Endangered Species Under the Endangered Species Act
    BEFORE THE SECRETARY OF INTERIOR PETITION TO LIST THE RELICT LEOPARD FROG (RANA ONCA) AS AN ENDANGERED SPECIES UNDER THE ENDANGERED SPECIES ACT CENTER FOR BIOLOGICAL DIVERSITY SOUTHERN UTAH WILDERNESS ALLIANCE PETITIONERS May 8, 2002 EXECUTIVE SUMMARY The relict leopard frog (Rana onca) has the dubious distinction of being one of the first North American amphibians thought to have become extinct. Although known to have inhabited at least 64 separate locations, the last historical collections of the species were in the 1950s and this frog was only recently rediscovered at 8 (of the original 64) locations in the early 1990s. This extremely endangered amphibian is now restricted to only 6 localities (a 91% reduction from the original 64 locations) in two disjunct areas within the Lake Mead National Recreation Area in Nevada. The relict leopard frog historically occurred in springs, seeps, and wetlands within the Virgin, Muddy, and Colorado River drainages, in Utah, Nevada, and Arizona. The Vegas Valley leopard frog, which once inhabited springs in the Las Vegas, Nevada area (and is probably now extinct), may eventually prove to be synonymous with R. onca. Relict leopard frogs were recently discovered in eight springs in the early 1990s near Lake Mead and along the Virgin River. The species has subsequently disappeared from two of these localities. Only about 500 to 1,000 adult frogs remain in the population and none of the extant locations are secure from anthropomorphic events, thus putting the species at an almost guaranteed risk of extinction. The relict leopard frog has likely been extirpated from Utah, Arizona, and from the Muddy River drainage in Nevada, and persists in only 9% of its known historical range.

Corresponding author: Dillon Jones, [email protected] Abstract Urban herpetology deals with the interaction of amphibians and reptiles with each other and their environment in an ur- ban setting. As such, well-preserved natural areas within urban environments can be important tools for conservation. Edith L. Moore Nature Sanctuary is an 18-acre wooded sanctuary located west of downtown Houston, Texas and is the headquarters to Houston Audubon Society. This study compared iNaturalist data with results from visual encounter surveys and aquatic funnel traps. Results from these two sources showed 24 species belonging to 12 families and 17 genera of herpetofauna inhabit the property. However, several species common in surrounding areas were absent. Combination of data from community science and traditional survey methods allowed us to better highlight herpe- tofauna present in the park besides also identifying species that may be of management concern for Edith L. Moore.

  • Baseline Population Inventory of Amphibians on the Mountain Longleaf National Wildlife Refuge and Screening for the Amphibian Disease Batrachochytrium Dendrobatidis
    Baseline Population Inventory of Amphibians on the Mountain Longleaf National Wildlife Refuge and Screening for the Amphibian Disease Batrachochytrium dendrobatidis This study was funded by the U.S. Fish & Wildlife Service Southeast Region Inventory and Monitoring Network FY 2012 September 2013 Gregory Scull1 Chester Figiel1 Mark Meade2 Richard Watkins2 1U.S. Fish and Wildlife Service 2Jacksonville State University, Jacksonville, Alabama The findings and conclusions in this article are those of the author(s) and do not necessarily represent the views of the U.S. Fish and Wildlife Service. Introduction: Amphibians are facing worldwide population declines, range contractions, and species extinction. Within the last 30 years, over 200 species have become extinct and close to one-third of the world’s amphibians are imperiled (IUCN, 2010). A recent trend analysis indicates that amphibian decline may be even more widespread and severe than previously realized and includes species for which there has been little conservation concern or assessment focus in the past (Adams et al. 2013). Factors such as invasive species, disease, changes in land use, climate change effects and the interactions of these factors all form current hypotheses that attempt to explain this dilemma (McCallum, 2007). This is alarming considering that the Southeast contains the highest level of amphibian diversity in the United States. It is imperative that we obtain and maintain current information on amphibian communities inhabiting our public lands so that we can adaptively manage resources for their long-term survival. Although a number of causes appear related to amphibian declines in recent years, one of the leading factors is the infectious disease known as chytridiomycosis.

  • The Rio Grande Leopard Frog (Lithobates Berlandieri) and Other Introduced and Native Riparian Herpetofauna of the Coachella Valley, Riverside County, California
    California Fish and Game 105(2):48-71; 2019 The Rio Grande leopard frog (Lithobates berlandieri) and other introduced and native riparian herpetofauna of the Coachella Valley, Riverside County, California David M. Goodward* and Michael D. Wilcox 22430 Pico Street, Grand Terrace, CA 92313, USA (DMG) Wood Environment and Infrastructure Solutions, 1845 Chicago Ave., Suite D, Riverside, CA 92507, USA (MDW) *Correspondent: [email protected] The Coachella Valley of southeastern California has gradually developed a riparian herpetofauna since the conversion of desert land to agricultural and urban landscapes and the formation of the Salton Sea in the early 1900s. Most of these species originally spread from the Colorado River to the Imperial Valley through natural channel shifts long ago, and more recently through the All-American Canal. Some of these riparian species then moved northward into the Coachella Valley of Riverside County, situated at the north end of the Salton Sea, namely, Woodhouse’s Toad (Anaxyrus woodhousii), Great Plains Toad (Anaxyrus cognatus), Rio Grande Leopard Frog (Lithobates berlandieri), Spiny Softshell (Apalone spinifera), and Checkered Gartersnake (Thamnophis marcianus). The Red-eared Slider (Trachemys scripta elegans) was introduced from captivity, and the Ameri- can Bullfrog (Lithobates catesbeianus) may have arrived from multiple sources. The most recent immigrant is the Rio Grande Leopard Frog. This species has colonized the agricultural southern part of the Coachella Valley and has begun to move into the urbanized northern portion. This frog has the potential to negatively affect native anurans if it spreads further. The current distribution, timing of introduction, and suspected origins of all riparian herpetofauna in the Coachella Valley are discussed.
