Management and Conservation Effects of Tail-Clipping on Survivorship and Growth of Larval Salamanders
نویسندگان
چکیده
Tissue samples used for genetic analyses are increasingly necessary for proper management of rare or endangered species, yet growing evidence suggests that traditional methods used to sample or mark amphibians have detrimental fitness effects. We used a semi-natural mesocosm experiment to determine the effect of larval tail-clipping on growth and survival of the endangered California tiger salamander. Even with relatively extreme levels of tail loss, we found no effect on survival, mass, or snout-vent length. We recommend larval tail-clipping as a low-impact method for collecting tissue samples from pond-breeding amphibians. 2013 The Wildlife Society.

Effects of Tail Clipping on Larval Performance and Tail Regeneration Rates in the Near Eastern Fire Salamander, Salamandra infraimmaculata
Tail-tip clipping is a common technique for collecting tissue samples from amphibian larvae and adults. Surprisingly, studies of this invasive sampling procedure or of natural tail clipping--i.e., bites inflicted by predators including conspecifics--on the performance and fitness of aquatic larval stages of urodeles are scarce. We conducted two studies in which we assessed the effects of poster...
متن کاملEffects of urbanization on occupancy of stream salamanders.
Urban development is the most common form of land conversion in the United States. Using a before-after control-impact study design, we investigated the effects of urbanization on larval and adult stages of southern two-lined salamanders (Eurycea cirrigera) and northern dusky salamanders (Desmognathus fuscus). Over 5 years, we estimated changes in occupancy and probabilities of colonization and...

Food availability and temperature are known to trigger phenotypic change, but the interactive effects between these factors are only beginning to be considered. The aim of this study was to examine the independent and interactive effects of long-term stochastic food availability and water temperature on larval survivorship, growth and development of the striped marsh frog, Limnodynastes peronii...
متن کاملLarval long- toed salamanders incur nonconsumptive effects in the presence of nonnative trout
Predators can influence prey directly through consumption or indirectly through nonconsumptive effects (NCEs) by altering prey behavior, morphology, and life history. We investigated whether predatoravoidance behaviors by larval longtoed salamanders (Ambystoma macrodactylum) in lakes with nonnative trout result in NCEs on morphology and development. Field studies in lakes with and without trout...
