    LIFE HISTORY OF THE COASTAL TAILED FROG (ASCAPHUS TRUEI) ACROSS AN ELEVATIONAL GRADIENT IN NORTHERN CALIFORNIA By Adrian Daniel Macedo A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Biology Committee Membership Dr. John O. Reiss, Committee Chair Dr. Daniel C. Barton, Committee Member Dr. Karen L. Pope, Committee Member Dr. Sharyn B. Marks, Committee Member Dr. Erik Jules, Program Graduate Coordinator December 2019 ABSTRACT LIFE HISTORY OF THE COASTAL TAILED FROG (ASCAPHUS TRUEI) ACROSS AN ELEVATIONAL GRADIENT IN NORTHERN CALIFORNIA Adrian D. Macedo The life history of a species is described in terms of its growth, longevity, and reproduction. Unsurprisingly, life history traits are known to vary in many taxa across environmental gradients. In the case of amphibians, species at high elevations and latitudes tend to have shorter breeding seasons, shorter activity periods, longer larval periods, reach sexual maturity at older ages, and produce fewer and larger clutches per year. The Coastal Tailed Frog (Ascaphus truei) is an ideal species for the study of geographic variation in life history because it ranges across most of the Pacific Northwest from northern California into British Columbia, and along its range it varies geographically in larval period and morphology. During a California Department of Fish and Wildlife restoration project in the Trinity Alps Wilderness, I had incidental captures of Coastal Tailed Frog larvae and adults. To date, no population across the species’ range has been described above 2000m. These populations in the Trinity Alps range from 150m to over 2100m in elevation, and those that are in the higher part of the range are likely living at the species’ maximum elevational limit.

  • Ecol 483/583 – Herpetology Lab 3: Amphibian Diversity 2: Anura Spring 2010
    Ecol 483/583 – Herpetology Lab 3: Amphibian Diversity 2: Anura Spring 2010 P.J. Bergmann & S. Foldi (Modified from Bonine & Foldi 2008) Lab objectives The objectives of today’s lab are to: 1. Familiarize yourself with Anuran diversity. 2. Learn to identify local frogs and toads. 3. Learn to use a taxonomic key. Today’s lab is the second in which you will learn about amphibian diversity. We will cover the Anura, or frogs and toads, the third and final clade of Lissamphibia. Tips for learning the material Continue what you have been doing in previous weeks. Examine all of the specimens on display, taking notes, drawings and photos of what you see. Attempt to identify the local species to species and the others to their higher clades. Quiz each other to see which taxa are easy for you and which ones give you troubles, and then revisit the difficult ones. Although the Anura has a conserved body plan – all are rather short and rigid bodied, with well- developed limbs, there is an incredible amount of diversity. Pay close attention to some of the special external anatomical traits that characterize the groups of frogs you see today. You will also learn to use a taxonomic key today. This is an important tool for correctly identifying species, especially when they are very difficult to distinguish from other species. 1 Ecol 483/583 – Lab 3: Anura 2010 Exercise 1: Anura diversity General Information Frogs are a monophyletic group comprising the order Anura. Salientia includes both extant and extinct frogs. Frogs have been around since the Triassic (~230 ma).

  • The Case of the Missing Frogs by Bryan Hamilton Why Are There No
    The Case of the Missing Frogs By Bryan Hamilton Why are there no frogs in Great Basin National Park? Great Basin National Park seems like a perfect refuge for frogs, with plenty of water--ten perennial streams, hundreds of springs, and six alpine lakes, but apparently there are no amphibians. During 2002, an amphibian inventory was conducted within Great Basin National Park. Crews surveyed perennial streams, springs, and alpine lakes, but did not observe any adult amphibians, tadpoles, or egg masses. The reasons for this are unclear, but apparently frog distribution depends on more than just abundant water. Lack of suitable breeding habitat is a major limiting factor in amphibian distribution. Most amphibians require still or extremely slow moving water to lay their eggs in. High gradient streams in the Park do not provide appropriate breeding habitat. The hundreds of springs in the Park may provide this habitat, however, no amphibians were found at the dozens of springs surveyed this year. Isolation from source populations is another limiting factor. Streams leave the Park and then quickly disappear underground. Amphibian populations near the Park are not directly connected to these streams. Thus no corridors exist between the Park and nearby amphibian populations. One amphibian species that does not require aquatic corridors for migration is the Great Basin Spadefoot (Spea intermontana), commonly referred to as a "toad." Spadefoots are distinguished from "true toads" (members of the family Bufonidae) by a black wedge shaped spade on their hind feet, used for burrowing. Spadefoots move considerable distances over land during spring and summer rains, travelling to breeding sites.

There have been major declines in many species. For example, where vast numbers of leopard frogs could be found on the banks of the Jordan only twenty years ago, I have been unable to find even a single individual for years! On the other hand, populations of introduced exotic species like the bull frog are apparently expanding. A few like the striped chorus frog seem to be holding their own. Cars, and predators like foxes and domestic and introduced exotics like cats and raccoons have all played a part in some of these declines. Some species may be especially sensitive to chemicals like the herbicide Roundup, the depletion of earth’s protective ozone layer, and a disease called kitrid which have all been implicated in the demise of many species worldwide. Only three natives and the one exotic (see above) are currently common in the river’s corridor. One species is endangered, others are threatened as amphibians in general appear to a be the veritable Acanary in the mine@ for predicting the ecological demise of many ground-based vertebrates, unless we clean up our act and start caring for them.

  • Riparian Management and the Tailed Frog in Northern Coastal Forests
    Forest Ecology and Management 124 (1999) 35±43 Riparian management and the tailed frog in northern coastal forests Linda Dupuis*,1, Doug Steventon Centre for Applied Conservation Biology, Department of Forest Sciences, University of British Columbia, Vancouver, BC, Canada V6T 1Z4 Ministry of Forests, Prince Rupert Region, Bag 5000, Smithers, BC, Canada V0J 2N0 Received 28 July 1998; accepted 19 January 1999 Abstract Although the importance of aquatic environments and adjacent riparian habitats for ®sh have been recognized by forest managers, headwater creeks have received little attention. The tailed frog, Ascaphus truei, inhabits permanent headwaters, and several US studies suggest that its populations decline following clear-cut logging practices. In British Columbia, this species is considered to be at risk because little is known of its abundance, distribution patterns in the landscape, and habitat needs. We characterized nine logged, buffered and old-growth creeks in each of six watersheds (n 54). Tadpole densities were obtained by area-constrained searches. Despite large natural variation in population size, densities decreased with increasing levels of ®ne sediment (<64 mm diameter), rubble, detritus and wood, and increased with bank width. The parameters that were correlated with lower tadpole densities were found at higher levels in clear-cut creeks than in creeks of other stand types. Tadpole densities were signi®cantly lower in logged streams than in buffered and old-growth creeks; thus, forested buffers along streams appear to maintain natural channel conditions. To prevent direct physical damage and sedimentation of channel beds, we suggest that buffers be retained along permanent headwater creeks. Creeks that display characteristics favoring higher tadpole densities, such as those that have coarse, stable substrates, should have management priority over less favorable creeks.

  • Toadally Frogs Frog Wranglers
    Toadally Frogs Frog Wranglers P rogram Theme: • Frogs are toadally awesome! P rogram Messages: • Frogs are remarkable creatures • A frogs ability to adapt to its environment is evident in it physiology • Frogs are extremely sensitive to their surroundings and as a result are considered to be an indicator species P rogram Objectives: • Gallery Participants will observe live frogs face-to-face • Gallery Participants will be able to describe several physical features and unique qualities of the White’s tree frog • Gallery Participants will get excited about frogs Frog Wrangling Procedure 1. Wash and dry your hands. You may use regular tap water and light soap, but insure that you rinse your hands thoroughly. 2. Move frog from the Public Programs suite into carrying case. Whenever you transport your frog from the Public Programs suite to the exhibit, please carefully remove them from the habitat terrarium and place them in the small red carrying case (cooler). This will prevent the animal from becoming stressed as it is moved through the Museum. 3. Prepare your audience. Prior to bring out the live frog, ensure that everyone is seated and that you have asked your audience not to move quickly. Sit on the floor as well; this will ensure that if the frog leaps from your hands, it would not have far to fall. 4. Wet your hands. When you are ready to show the frog as part of your demonstration, please moisten your hands with the spray bottle. This will help minimize your dry skin from sucking the moisture out of the frog.

  • Amphibian Protocol the Survey Protocols Below Are from BC Frog Watch
    Amphibian Protocol The survey protocols below are from BC Frog Watch: http://www.env.gov.bc.ca/wld/frogwatch/frogwatching/how.htm Because populations fluctuate each year in relation to climatic conditions, such as snowpack or spring rains, long-term data are required to accurately assess the status of a species or the productivity of a wetland. There are a number of techniques that can be used to monitor amphibians. The two described below can be used alone or in combination. Please note: Any protocol that involves wading in a wetland must consider the possibility of the transmission of infection from one area to another. Consult the BC Disinfection Protocol. Call Surveys This technique is used to survey frogs and toads, species which vocalize during the breeding season. Surveyors visit the monitoring site(s) in spring and listen for calling males , (this is a link to a recording of each species’ breeding call) recording the species and approximate number of each. Repeat surveys increase the probability that species will be detected. Define a survey transect along or through your wetland. Describe in enough detail that someone else can follow the same route. It can be along the edge of open water or any other route that makes sense. Use GPS locations to confirm the route if possible. Follow the same transect on each survey. This technique is relatively easy, inexpensive, and takes little training, but only one life stage can be surveyed and the technique is only effective for some species and geographic locations (see Table 1 below). Questions you can answer with this technique: • What species of frog and toad call at this site in any given year? • Do the same species breed at the site each year? • Approximately how many males are in the breeding population at this site in any given year? • When does breeding take place at this site each year and how long does it last? Visual Surveys All life stages can be surveyed visually at breeding sites or along roads and much information is gleaned from this survey technique.

    Amphibian Distribution Summary Mendocino Redwood Company Distribution of Coastal Tailed Frogs (Ascaphus truei), Red-Legged Frogs (Rana aurora and Rana draytonii), and Southern Torrent Salamanders (Rhyacotriton variegatus) on Mendocino Redwood Company Forestlands. Fisheries Department Mendocino Redwood Company, LLC PO Box 489 Fort Bragg, CA 95437 Amphibian Distribution Summary Mendocino Redwood Company INTRODUCTION This report summarizes the results of the current distribution of coastal tailed frogs (Ascaphus truei), red-legged frogs (Rana aurora and Rana draytonii), and southern torrent salamanders (Rhyacotriton variegatus) on Mendocino Redwood Company forestlands. All of the acreage owned by MRC with suitable habitat was surveyed for the presence of these species. Coastal Tailed Frogs (Ascaphus truei) Coastal tailed frogs are uniquely adapted to life in cold, fast-flowing, high-gradient, perennial mountain streams and to some extent utilize trout-bearing streams (Nussbaum et al. 1983). Coastal tailed frogs prefer streams with dense, shaded habitat, low sediment loads, cool temperatures, high ambient humidity levels, and high water quality over much of their range (Bury and Corn 1988, Corn and Bury 1989, Welsh 1990, Hayes 1996). Diller and Wallace (1999) examined larval distribution of coastal tailed frogs related to channel bed characteristics. Larvae were “positively associated with cobble, boulder, and gravel substrates with lower embeddedness, and negatively associated with fine substrates.” Coastal tailed frogs are restricted to a narrow range of habitat types, in part because it requires cold temperatures and has one of the narrowest ranges of temperature tolerances of any frog species. This species typically lives in waters between 5o to 16oC (41o to 61oF) (Marshall et al.
