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. -

Guidance for Conserving Oregon's Native Turtles Including Best Management Practices
GUIDANCE FOR CONSERVING OREGON’S NATIVE TURTLES INCLUDING BEST MANAGEMENT PRACTICES the OREGON CONSERVATION STRATEGY the intent of this document is to facilitate better protection and conservation of oregon’s native turtles and their habitats. This document includes recommended Best Management Practices (BMPs) for protecting and conserving Oregon’s two native turtle species, the western painted turtle and the western pond turtle. While there are opportunities for all Oregonians to become more knowledgeable about and participate in turtle conservation efforts, this document is intended primarily for use by natural resource and land managers, land use planners, and project managers. The document has been peer-reviewed and the BMPs are supported by scientifically sound information. The BMPs are intended to be practical and cost-effective so that they can be readily used. Adherence to these BMPs does not necessarily constitute compliance with all applicable federal, state, or local laws. Acknowledgements This document was produced by the Oregon Department of Fish and Wildlife (ODFW) with significant financial and design contributions from The Port of Portland. Input and technical review was provided by the Oregon Native Turtle Working Group which is comprised of representatives from a variety of natural resource agencies, organizations, and institutions. This document arose out of a recommendation from the 2009 Native Turtle Conservation Forum, organized by the Oregon Native Turtle Working Group and hosted by the Oregon Zoo. More information -
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). -

Western Toad Taxonomy Description
WESTERN TOAD TAXONOMY Scientific name: Bufo boreas (Baird and Girard, 1852) Common name: Western toad Family: Bufonidae Taxonomic comments: Hybridizes with the red-spotted toad (Bufo punctatus) at Darwin Falls, Inyo County, California, and sometimes with Canadian toad (B. hemiophrys) in central Alberta. B. nelsoni was formerly included in this species. Molecular data indicate that B.exsul is phylogenetically nested within B. canorus; further data are needed to determine whether B. exsul should be subsumed with B. canorus (Shaffer et al. 2000). "Stephens (2001) examined mitochondrial DNA from 8 Yosemite toads (selected from the samples examined by Shaffer et al. (2000) to represent the range of variability found in that study) and 173 western toads. Stephens' data indicate that Bufo in the Sierra Nevada occur in northern and southern evolutionary groups, each of which include both Yosemite and western toads (i.e., toads of both species are more closely related to each other within a group than they are to members of their own species in the other group). Further genetic analysis of Yosemite toads sampled from throughout their range, and from other toad species surrounding their range is needed to fully understand the evolutionary history and appropriate taxonomic status of the Yosemite toad." (USFWS 2002). DESCRIPTION Basic description: A toad. General description: A chunky, short-legged, warty amphibian with dominant parotoid glands at the back of the head and a conspicuous light-colored stripe running down the middle of the back. Coloration varies from brown, green to gray above and white with dark mottling below. Females are usually larger, more blotched, and have rougher skin than males (Hodge 1976, MacDonald 2003). -

Species status assessment report for the Columbia spotted frog (Rana luteiventris), Great Basin Distinct Population Segment. Reno Fish and Wildlife Office, Reno, Nevada. vii + 86 pp. ii Executive Summary In this Species Status Assessment (SSA), we evaluate the biological status of Columbia spotted frogs (Rana luteiventris) in the Great Basin both currently and into the future through the lens of the species’ resiliency, redundancy, and representation. This SSA Report provides a comprehensive assessment of biology and natural history of Columbia spotted frogs and assesses demographic risks, stressors, and limiting factors. Herein, we compile biological data and a description of past, present, and likely future stressors (causes and effects) facing Columbia spotted frogs in the Great Basin. Columbia spotted frogs are highly aquatic frogs endemic to the Great Basin, northern Rocky Mountains, British Columbia, and southeast Alaska. Columbia spotted frogs in southeastern Oregon, southwestern Idaho, and northeastern and central Nevada make up the Great Basin Distinct Population Segment (DPS; Service 2015, pp. 1–10). Columbia spotted frogs are closely associated with clear, slow-moving streams or ponded surface waters with permanent hydroperiods and relatively cool constant water temperatures (Arkle and Pilliod 2015, pp. 9–11). In addition to permanently wet habitat, streams with beaver ponds, deep maximum depth, abundant shoreline vegetation, and non-salmonid fish species have the greatest probability of being occupied by Columbia spotted frogs within the Great Basin (Arkle and Pilliod 2015, pp. -
