“…Above average rainfall in one year may increase the terrestrial prey base for adult females, which may then translate into greater reproductive success (through more "fit" offspring) in the subsequent year. For instance, Milanovich et al [132] documented that, in the western slimy salamander (Plethodon albagula), the amount of precipitation one year prior to oviposition was correlated with average clutch size in the subsequent year. Food availability has been shown to affect traits related to individual fitness in other species of salamanders as well (Figure 3; [133,134]).…”

Abstract:As part of an overall decline in biodiversity, populations of many organisms are declining and species are being lost at unprecedented rates around the world. This includes many populations and species of amphibians. Although numerous factors are affecting amphibian populations, we show potential direct and indirect effects of climate change on amphibians at the individual, population and community level. Shifts in amphibian ranges are predicted. Changes in climate may affect survival, growth, reproduction and dispersal capabilities. Moreover, climate change can alter amphibian habitats including vegetation, soil, and hydrology. Climate change can influence food availability, predator-prey relationships and competitive interactions which can alter community structure. Climate change can also alter pathogen-host dynamics and greatly influence how diseases are manifested. Changes in climate can interact with other stressors such as UV-B radiation and contaminants. The interactions among all these factors are complex and are probably driving some amphibian population declines and extinctions. OPEN ACCESSDiversity 2010, 2 282

“…1). A long-term dataset (Milanovich et al, 2006) provided a framework of ecological relationships of P. albagula against which we compared post-burning data. Our goal was to investigate affects of a prescribed burn on a population of P. albagula in south-central Arkansas.…”

“…During spring and autumn, P. albagula uses the area adjacent to the mine, but takes refuge from heat and desiccation in the mine during summer. The mine is used for brooding clutches in autumn and winter (Milanovich et al, 2006;.…”

“…Intervals for fires in this area averaged ,10 years in the pre-settlement Ouachita Mountains region with Reproductive and age-composition data from before the burn (August 1983-January 2005) were available for our analysis (Milanovich et al, 2006) with 30 postburn visits during March 2005-October 2007. During each visit, we counted number of clutches, number of eggs per clutch (fecundity), total number of eggs in all clutches per year, and measured diameter of eggs (embryo and surrounding membrane; to the nearest 0.1 mm) for each available clutch.…”

“…Although ovipositioning females only have 1 clutch/year, and because measurements were made across multiple years, multiple clutches from a single female across years may be included in the analysis. Females typically oviposit every other year; therefore, effects from the burn may not be apparent until subsequent years, as females acquire resources for reproduction the year preceding oviposition (Milanovich et al, 2006). Milanovich et al (2006) analyzed long-term data on fecundity from this population and suggested that there was no relationship between size of body and fecundity; therefore, reproductive data from before and after the burn were tested with individual and year of study as independent variables.…”

Several biogeographic studies of salamanders have described relationships between salamander body size and climate. We specifically selected Plethodon cinereus as a widely distributed species that was well represented in museum collections to investigate the effects of warming climate on adult body size. We found a positive correlation between mean maximum July temperature and body size, and a negative correlation between precipitation of the driest month and body size. Surface-collected adult P. cinereus were 2.3% larger in warmer counties on the coastal plain compared with cooler counties in the Appalachian Mountains. We compared salamanders collected between 1950 and 1970 versus those collected between 1980 and 2000 and found that body size increased 1.8% in counties on the coastal plain where mean maximum July temperatures had also increased by 0.5-1.2°C. Warming temperatures alone, however, did not adequately account for the observed size increases, because body size also increased 1.3% in places that experienced less than 0.25°C warming, but that difference was not statistically significant.
