1. Amphibian Conservation in Britain: A 40-Year History

Author:
Beebee Trevor J. C.

Journal of Herpetology 2014 v.48 no.1 pp. 2-12

Subject:
ultraviolet radiation; funding; salamanders and newts; acid deposition; Epidalea calamita; pesticides; surveys; urban population; habitats; climate change; frogs; Bufo bufo; inbreeding; indigenous species; Rana temporaria; intensive farming; Pelophylax; mortality; toads; United Kingdom
Abstract:
... Agricultural intensification, starting during the Second World War, precipitated declines in all seven native species of amphibians in Britain. Problems in the United Kingdom (U.K.) therefore predated recognition of global amphibian declines and were due to relatively simple causes, notably habitat modification and destruction. Pesticides, acid rain, ultraviolet radiation, climate change, and dise ...

Abstract:
... Understanding amphibian habitat associations allows us to assess the impacts of environmental change on amphibian populations. We studied the habitat associations of five anurans in the Chihuahuan Desert of southern New Mexico, USA. We used amphibian call surveys at 36 ephemeral water bodies and recorded an index of abundance for each species. We used GIS to identify vegetation communities (e.g., ...

Rana temporaria; agricultural land; biodiversity; conservation status; drainage; edge effects; environmental factors; frogs; habitats; intensive farming; landscapes; pollution; ponds; risk factors; risk perception; wetlands; Ireland
Abstract:
... Ponds are an ephemeral feature of the landscape but their large-scale loss can have profound implications for biodiversity and the persistence of amphibian populations. We quantified rates of pond loss throughout Ireland over a period of approximately 125 yr. Environmental parameters and perceived risk factors associated with the current occurrence and density of the Common Frog, Rana temporaria, ...

Abstract:
... Basic information on species distribution and abundance is often lacking, even for common species. The historically abundant Mountain Yellow-legged (Rana sp.) and Pacific Treefrog (Pseudacris sp.) species complexes occur sympatrically and are exposed to similar threats. We evaluated the status of these species complexes on national forest lands in the Sierra Nevada, California as part of a long-te ...

Abstract:
... Ocean temperature is a key determinant of the distribution and phenology of marine life, particularly poikilotherms. We examined effects of ocean temperature on nesting phenology and fecundity for Loggerhead Sea Turtles (Caretta caretta) in the northern Gulf of Mexico using long-term nesting survey data from northwest Florida. The first clutch of the year was deposited earlier when sea surface tem ...

Abstract:
... Restoration efforts are ongoing to protect the threatened California Red-Legged Frog (Rana draytonii) from further decline, but conserving species that have aquatic and terrestrial life stages can be challenging. For example, although it is clear that aquatic habitat must be protected for breeding, less is known about the importance of terrestrial habitat. Food web linkages remain largely unknown ...

Abstract:
... Amphibian road mortality is a conservation concern that is receiving increased attention by the conservation community, especially given the increasing number of studies quantifying numbers of individuals that are run over by vehicles during seasonal migrations to and from breeding wetlands and during nonmigratory activity bouts on roadways.

Abstract:
... Survival is an important component of population growth rate. We use data from a 9-yr mark-recapture study to estimate annual and monthly survival probabilities of adult salamanders (Salamandra salamandra). Monthly survival probability was 0.98–0.99 and did not differ between summer and winter. Annual survival probability was 0.86. These estimates are similar to estimates for other salamander spec ...

Abstract:
... Stream ecosystems are particularly sensitive to urbanization, and tolerance of water-quality parameters is likely important to population persistence of stream salamanders. Forecasted climate and landscape changes may lead to significant changes in stream flow, chemical composition, and temperatures in coming decades. Protected areas where landscape alterations are minimized will therefore become ...

Abstract:
... Ranaviruses are emerging as serious pathogens across ectothermic taxa, recently causing mass die-offs including entire chelonian populations. Amphibians may serve as reservoirs for chelonian infections. To assess this idea and determine whether chelonians in the Midwest are infected with (or at risk for) ranavirus infections, we tested for presence of ranavirus infections among sympatric larval am ...

Abstract:
... Dispersal and vicariance are the principal mechanisms responsible for the formation of biogeographic patterns, driven or maintained by the role of past and current barriers to dispersal. Southwest Portugal harbors a rich endemic fauna and flora where strongly differentiated taxa can be observed, suggesting ancient isolating mechanisms acted in this region. In this study, we used information from t ...
