The need for long-term demographic studies on apparently healthy amphibian populations led us to undertake an intensive examination of a population of Spotted Salamanders (Ambystoma maculatum) at a small, temporary pond in Ohio. From 2005 to 2014, we

Climate-related changes in breeding phenology have been demonstrated across a range of taxonomic groups. Amphibian phenology may be particularly susceptible to environmental variability, b...

Spotted Salamanders (Ambystoma maculatum) and members of the Blue-Spotted Salamander complex (Ambystoma laterale-jeffersonianum complex) often share terrestrial and wetland habitats, allowing controlled comparison of their life-history strategies. We

We conducted a 2-year study of terrestrial habitat use by spotted salamanders (Ambystoma maculatum), blue-spotted salamanders (A. laterale), wood frogs (Rana sylvatica), and eastern newts (Notophthalmus viridescens) within blocks of forest enclosed b

A critical threshold exists when the relationship between the amount of suitable habitat and population density or probability of occurrence exhibits a sudden, disproportionate decline as habitat is lost. Critical thresholds are predicted by a variet

Amphibians experience indeterminate growth, but although factors affecting larval growth are relatively well studied, less is known about correlates of postmetamorphic growth. We measured areas between lines of arrested growth (inter-LAG) to determin

We sampled blood from free-living spotted salamanders (Ambystoma maculatum) to test whether differences in the concentrations of a stress hormone (corticosterone) were associated with different qualities of breeding and migration habitat. Spotted sal

A non-lethal technique for drawing repeated blood samples from spotted salamanders (Ambystoma maculatum) was used to examine sex, seasonal, and capture technique differences in the physiological stress response under natural, undisturbed conditions.

We studied an Ambystoma maculatum (Spotted Salamander) population whose available terrestrial habitat varied in forest age, forest extent, and edge type to determine how microhabitats differed among habitats, whether A. maculatum displayed a nonrando
