This book was released on 2015 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population estimates for adult long-toed salamander (Ambystoma macrodactylum) at Linnet Lake in Waterton Lakes National Park, Alberta, showed a 60% decline from 1994 and 2008 -2009. To prevent further decline, in 2008 Parks Canada installed four under-road crossing structures (tunnels) and directional fencing along the road bordering Linnet Lake to reduce road mortality, which was known to be high. Parks later learned that predacious fish had colonized the lake, likely during natural flooding. In 2010 and 2011, Parks removed and relocated 35000 fish from Linnet Lake over 11 days of trapping. Measures intended to restore wildlife populations to historic levels often go unmonitored, and success or failure is not systematically assessed. Long-toed salamanders are small and delicate, and are difficult to monitor when they inhabit the terrestrial environment during the 10 - 11 month non-breeding season. To determine the status of the Linnet Lake long-toed salamander population and investigate terrestrial movement patterns (orientation) and habitat-use, I conducted research in 2013 and 2014 at Linnet Lake and a nearby reference site (Stable Pond, 1.2 km away). I conducted a mark-recapture study at Linnet Lake by marking salamanders with passive integrated transponder (PIT) tags, and I used radio frequency identification (RFID) antennas and cameras in tunnels to monitor use by tagged individuals and compare the two methods. I also used PIT tags to mark salamanders at Stable Pond and, using a home-made portable RFID antenna (scanner), I conducted "PIT telemetry" to locate tagged animals in the terrestrial environment at both sites and tested the scanners read range. At Linnet Lake, I found no increase in adult salamander population size from estimates made during the 2008 -2009 study and I found little evidence of recruitment when I compared demographic data to Stable Pond. Population estimates of 1380 (95% CI: 1138, 1702) in 2013 and 706 (95% CI: 575, 893) in 2014 indicate a declining population at Linnet Lake and raise concern regarding the viability of the population and urgency for conservation efforts. RFID antennas were 6.5 times more likely than cameras to detect a tagged salamander entering or exiting tunnels. Salamander orientation was non-uniform at both study sites, with movement patterns staying consistent between years at Linnet Lake and differing between age classes and as salamanders moved further from the shore at Stable Pond. Using PIT telemetry, I relocated 32 individuals in the terrestrial habitats around Linnet Lake and 80 at Stable Pond. I was able to locate and characterize nine overwintering sites and each was associated with decomposing tree roots. Tests of the portable RFID antenna's read range in three substrates (soil, rock, water) at multiple depths showed the highest read range in water, and a non-linear effect of depth on horizontal read range. This study provides important data for monitoring the long-term effects of mitigation efforts at Linnet Lake, and demonstrates the utility of RFID and PIT tags for tracking small terrestrial vertebrates and monitoring the use of road-crossing structures.

Available in PDF, EPUB and Kindle. Book excerpt: Roads may threaten the persistence of wildlife populations by acting as barriers to movement and/or sources of increased mortality across the landscape. Amphibians and reptiles have been identified as being particularly susceptible to negative road impacts. Many species migrate annually among habitats to support basic life history requirements such as breeding, development, foraging, and overwintering. For these species, individuals may need to successfully cross roads multiple times each year for the population to persist. Many are slow-moving and freeze in the presence of danger, making it almost impossible for them to avoid oncoming vehicles. Although there are a plethora of road mortality location and count data, the effects of road mortality on the long-term viability of amphibian and reptile populations and metapopulations are mostly unknown due to a lack of information on their abundance, vital rates, behavior, and spatial and temporal dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: Amphibian Conservation is the fourth in the series of Synopses of Conservation Evidence, linked to the online resource www.ConservationEvidence.com. This synopsis is part of the Conservation Evidence project and provides a useful resource for conservationists. It forms part of a series designed to promote a more evidence-based approach to biodiversity conservation. Others in the series include bee, bird, farmland and bat conservation and many others are in preparation. Approximately 32% of the 7,164+ amphibian species are currently threatened with extinction and at least 43% of species are declining. Despite this, until recently amphibians and their conservation had received little attention. Although work is now being carried out to conserve many species, often it is not adequately documented. This book brings together and summarises the available scientific evidence and experience relevant to the practical conservation of amphibians. The authors consulted an international group of amphibian experts and conservationists to produce a thorough summary of what is known, or not known, about the effectiveness of amphibian conservation actions across the world. "The book is packed with literature summaries and citations; a veritable information goldmine for graduate students and researchers. It also admirably provides decision makers with a well-researched resource of proven interventions that can be employed to stem/reverse the decline of amphibian populations." -John G Palis, Bulletin of the Chicago Herpetological Society

Available in PDF, EPUB and Kindle. Book excerpt: The long-toed salamander (Ambystoma macrodactylum) is a Species of Special Concern in Alberta because it has a limited breeding range, populations are isolated and discontinuously distributed, it appears to be vulnerable to various types of habitat disturbance, and some populations may be decling. This plan recommends various ways to conserve long-toed salamander populations and habitat, including regular monitoring of historic breeding populations, avoid removal, alteration, and contamination of key breeding ponds; protect habitat around key breeding ponds with protective notations (PNTs) that reduce disturbance and maintain vegetative cover; and improve communication with public, landowners, industry, and government.--Document.
