Recovery Strategy for the Pacific Giant Salamander (Dicamptodon Tenebrosus) in British Columbia British Columbia Recovery Strategy Series Recovery Strategy for the Pacific Giant Salamander (Dicamptodon tenebrosus) in British Columbia Prepared by the Pacific Giant Salamander Recovery Team April 2010 About the British Columbia Recovery Strategy Series This series presents the recovery strategies that are prepared as advice to the Province of British Columbia on the general strategic approach required to recover species at risk. The Province prepares recovery strategies to meet its commitments to recover species at risk under the Accord for the Protection of Species at Risk in Canada, and the Canada – British Columbia Agreement on Species at Risk. What is recovery? Species at risk recovery is the process by which the decline of an endangered, threatened, or extirpated species is arrested or reversed, and threats are removed or reduced to improve the likelihood of a species’ persistence in the wild. What is a recovery strategy? A recovery strategy represents the best available scientific knowledge on what is required to achieve recovery of a species or ecosystem. A recovery strategy outlines what is and what is not known about a species or ecosystem; it also identifies threats to the species or ecosystem, and what should be done to mitigate those threats. Recovery strategies set recovery goals and objectives, and recommend approaches to recover the species or ecosystem. Recovery strategies are usually prepared by a recovery team with members from agencies responsible for the management of the species or ecosystem, experts from other agencies, universities, conservation groups, aboriginal groups, and stakeholder groups as appropriate. What’s next? In most cases, one or more action plan(s) will be developed to define and guide implementation of the recovery strategy. Action plans include more detailed information about what needs to be done to meet the objectives of the recovery strategy. However, the recovery strategy provides valuable information on threats to the species and their recovery needs that may be used by individuals, communities, land users, and conservationists interested in species at risk recovery.

Pacific Giant Salamander populations occur in the Chilliwack Forest District of British Columbia. The British Columbia Ministry of Environment is responsible for producing a recovery strategy for this species under the Accord for the Protection of Species at Risk in Canada. Environment Canada’s Canadian Wildlife Service also participated in the development of this document, as it is responsible under the federal Species at Risk Act (SARA) for this species (which is referred to as Coastal Giant Salamander under SARA), and is on the recovery team. ACKNOWLEDGEMENTS The original (2004) version of this report was prepared by Kristina Ovaska, Lennart Sopuck, Ross Vennesland, and Christian Engelstoft with input from Dennis Knopp and members of the Pacific Giant Salamander Recovery Team. The B.C. Ministry of the Environment has since developed a new set of recovery strategy format guidelines, and the Recovery Team is therefore submitting an updated version of the recovery strategy. Revisions and updates were made by Kym Welstead with assistance from Lennart Sopuck and Kristiina Ovaska. Jeff Brown, David Toews, Stephen Hureau, Marie-José Ribeyron, and Todd Manning provided useful comments on an earlier version of the revised strategy.

Reiss, Committee Chair Dr. Sharyn Marks, Committee Member Dr. Justus Ortega, Committee Member Dr. Micaela Szykman Gunther, Committee Member Dr. Erik Jules, Program Graduate Coordinator December 2020 ABSTRACT AN ECOMORPHOLOGICAL ANALYSIS OF LOCOMOTION IN LARVAE AND NEOTENES OF TWO SALAMANDER SPECIES: DICAMPTODON TENEBROSUS (STREAM-TYPE) AND AMBYSTOMA GRACILE (POND-TYPE). Ethan Snee Morphology is the physical expression of a species’ evolutionary history and adaptation to its environment and as such is tied to ecology. Salamander larvae have historically been separated into "pond-type" and "stream-type" groups based on their morphology, however no studies have been performed quantifying the relationship between morphology and ecology. In this study I utilized in-situ behavioral observations, morphological measurements, and in-lab performance tests of Dicamptodon tenebrosus (stream-type) and Ambystoma gracile (pond-type) to examine the relationship between salamander larval morphology and ecology. In the field, behavior was videorecorded during nighttime surveys; afterwards animals were captured and limb measurements were taken. Flow resistance was measured in the lab using a flow chamber and water velocity meter. Swim escapes were videorecorded in lab trials and analyzed using video analysis software. In the field, aquatic walking was the predominant form of movement observed in D. tenebrosus, constituting 98.1 percent of all movements; by contrast, aquatic walking made up only 65.4 percent of all movements in A.

  • Successful Reproduction of the Mole Salamander Ambystoma Talpoideum in Captivity, with an Emphasis on Stimuli Environmental Determinants
    SHORT NOTE The Herpetological Bulletin 141, 2017: 28-31 Successful reproduction of the mole salamander Ambystoma talpoideum in captivity, with an emphasis on stimuli environmental determinants AXEL HERNANDEZ Department of Environmental Sciences, Faculty of Sciences and Technics, University Pasquale Paoli of Corsica, Corte, 20250, France Author Email: [email protected] ABSTRACT - Generating and promoting evidence-based husbandry protocols for urodeles, commonly known as newts and salamanders, is urgently needed because most of the up-to-date ex situ programs are focused on frogs and toads than Urodela. Data on biology, life history, ecology and environmental parameters are lacking for many species and are needed to establish suitable husbandry and breeding conditions in captive environments. Two adult females and two adult males, of the mole salamander Ambystoma talpoideum successfully reproduced in captivity. It was found that reproduction of this species depends on various complex stimuli: including natural photoperiod 12:12, rainwater (acidic to neutral pH) and an aquarium full of various debris. Additionally high temperature variations ranging from 2 °C to 17 °C (a decrease followed by an increase) between November and February showed that it is possible to breed adults in aquariums provided the right stimuli are applied at the right moment of time in winter. A. talpoideum shows an explosive breeding mode as previously reported for the whole genus Ambystoma. INTRODUCTION with an emphasis on the environmental determinant stimuli involved. These data may assist in improving breeding these ince the 1980s, the current global amphibian extinction salamanders under artificial conditions. crisis has been discussed and acknowledged (Wake, A.

Ambystoma altamirani (Mountain Stream Siredon) is listed as Endangered by the International Union for Conservation of Nature (IUCN) Red List and as Threatened by the Mexican government. We report on the distribution, abundance, occupancy, population structure, and substrate use of A. altamirani, a stream dwelling salamander, along the Arroyo los Axolotes, Sierra de las Cruces, Mexico. We observed A. altamirani at least once during repeated surveys between February 2018 to December 2018 in 24 of 25 permanent 5-m long reaches separated by 40 m. The best model for occupancy had constant occupancy, detection, extinction, and colonization probabilities. Sites that dried at some time during the study had fewer observed individuals than those that did not dry. Size structure was relatively constant throughout the year, except for the appearance of small larvae in May, June, and July.
