Book excerpt: The mountain yellow-legged frog (Rana muscosa) has a disjunct distribution spread between the Sierra Nevada and southern California. The southern California population of mountain yellowlegged frog (MYLF) is recognized as a distinct population segment, and with less than 200 adults remaining in the wild, is protected under the federal endangered species act. I examined multiple facets of MYLF conservation across both wild and captive populations with the goal of improving current conservation efforts for the species. To understand the microhabitat needs of the MYLF I modeled the relationship between MYLF presence and 11 microhabitat variables on a per pool scale. Logistic regression models with Akaike's Information Criteria (AIC) were created for both frog and tadpole life stages. The frog model revealed that pool volume, pool leaf litter, bank leaf litter, and understory cover were important variables associated with frog presence. The tadpole model indicated that pool depth and understory cover were important and that pH was marginally important. This knowledge of the microhabitat needs of the MYLF can improve reintroduction efforts by allowing managers to make more informed decisions about where the MYLF should be reintroduced. To improve the reproductive output of a captive colony of MYLF with a history of low reproductive success, I measured the effect of an artificial hibernation period on multiple reproductive behaviors. Males subjected to advertisement calls of conspecific males demonstrated an increased phonotaxic response after a hibernation period (P = 0.01). However, females did not demonstrate a change in phonotaxic response after hibernation (P = 0.93). Examining the reproductive behaviors of breeding pairs I found that males who were hibernated had significantly higher frequencies of amplexus (P

This book was released on 2016-06-21 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.

Available in PDF, EPUB and Kindle. Book excerpt: The story of an expedition in search of the world's rarest and most exotic amphibians. On August 9, 2010, 33 teams from 21 countries were dispatched to search for the Lost Frogs identified by Conservation International. On their list were a host of species including, in the top ten most wanted, the Rio Pescado Stubfoot Toad, found only in Ecuador - which was to prove a triumphant rediscovery. Several months, a number of key rediscoveries - such as the Elegant Tropical Frog, last seen in 1937 and the Chalazodes Bubble-nest Frog - last seen in 1874 and two new species later, the Search for Lost Frogs had generated more than 650 news articles in 20 countries and over a billion potential viewers. Author Robin Moore was responsible for spearheading the Search for Lost Frogs and coordinating the teams. He also co-led two expeditions to Colombia and Haiti. In Colombia in search of the Mesopotamia Beaked Toad, the steamy jungles of the Choco yielded not the desired species but a brand new one - the Mr. Burns Toad, so-called because of an uncanny resemblance to the Simpsons' character; the species was selected as one of Time magazine's top ten new species of 2010. In Haiti the team found six frogs last seen 20 years before, including the Ventriloqual Frog, named for its ability to throw its voice. This fascinating new book tells the story of the expedition - its highs and lows, discoveries and failures and the campaign's ongoing work. Despite the campaign, one third of the world's amphibians remain threatened with extinction. Most of the species searched for were not found. But those that were provide a glimmer of hope. Understanding why these species have survived when many others have not should help us understand what makes these species different. In Search of Lost Frogs is a story of perseverance, disappointment, rediscovery, resilience, but ultimately of hope, written with passion and illustrated with the author's superb photographs.

Download or read book Ecological Impacts of Mountain Yellow legged Frog Rana Muscosa and Rana Sierrae Declines on Sierra Nevada Lake Communities written by Thomas Collier Smith and published by . This book was released on 2015 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mountain yellow-legged frogs (Rana muscosa and Rana sierrae) of California's Sierra Nevada have been extirpated from over 90% of their historic range, initially by introduced trout predators, and more recently by the emergence of the lethal amphibian chytrid fungus (Batrachochytrium dendrobatidis). Formerly widespread and abundant, mountain yellow-legged frogs are grazers and highly connected high level predators, living in low diversity, low productivity high elevation lakes. Here, I examine the extent to which frog extinctions impact Sierra Nevada lake communities. First, in a study that combined surveys of benthic macroinvertebrates in 22 lakes over 5 years with a reanalysis of benthic macroinvertebrate community data from over 150 lakes, I found no strong differences in benthic macroinvertebrate community diversity or composition between lakes with frogs vs. lakes without frogs. I also conducted experiments to evaluate the impact of tadpoles as grazers on benthic algae, and found that tadpoles do reduce algal biomass in artificial habitats, but that the effect can be small and may not outweigh the influence that abiotic variability has on algal biomass in lakes. Lastly, while I documented that large and periodic tadpole aggregations create biogeochemical hotspots of dissolved nitrogen, the phenomena may not be widespread enough to drive differences in diatom diversity in lakes with vs. without tadpoles. Within lakes, I found little indication that diatom community diversity and composition were responding to tadpole generated nitrogen hotspots as a fluctuation-dependent mechanism with potential to enhance diatom coexistence. While none of the ecological effects of mountain yellow-legged frogs and tadpoles that I observed suggests that their extinctions are having large impacts on Sierra Nevada lake communities, they should not be discounted as expendable, because there are many other ways in which these amphibians could be important in their communities.
