Burrow Availability and Desiccation Risk of Mole Salamanders (Ambystoma talpoideum) in Harvested versus Unharvested Forest Stands
Clearcutting and other forest management practices that remove canopy and disturb ground cover may exacerbate the risk of desiccation, particularly for newly metamorphosed amphibians, and results demonstrate that this risk is strongly mediated by the availability of burrows.
Effects of forest removal on amphibian migrations: implications for habitat and landscape connectivity
This study identifies one mechanism by which forest removal shapes the abundance and distribution of amphibians in terrestrial habitat, and suggests that conservation efforts should focus on preserving forest habitat adjacent to reproduction sites.
The combined effects of reactant kinetics and enzyme stability explain the temperature dependence of metabolic rates
It is shown that the temperature dependence of metabolic rate in ectotherms is well described by an enzyme‐assisted Arrhenius (EAAR) model that accounts for the temperature‐dependent contribution of enzymes to decreasing the activation energy required for reactions to occur.
Biomass export of salamanders and anurans from ponds is affected differentially by changes in canopy cover
Changes in canopy cover may induce a shift in the amphibians emerging from ponds, from primarily anurans in open canopy ponds to primarily salamanders in closed canopy ponds, and additional multispecies studies will determine whether these trends hold true for more diverse amphibian assemblages.
Habitat alteration increases invasive fire ant abundance to the detriment of amphibians and reptiles
Results show that S. invicta abundance increases with habitat disturbance and that this increased abundance has negative consequences for amphibians that remain in altered habitats, and suggest that the presence of invasive S. Invicta may compromise the utility of cover boards and other techniques commonly used in herpetological studies in the Southeast.
A New Stratified Aquatic Sampling Technique for Aquatic Vertebrates
A new type of passive-sampling minnow trap is developed that enables aquatic sampling at depths of up to 70 cm without drowning obligate air-breathers and demonstrated a heightened ability to capture bottom-dwelling animals that may otherwise be underrepresented by other trapping methodologies.
Innovative techniques for sampling stream-inhabiting salamanders
Although salamanders are excellent indicators of environmental health, the ability to catch them efficiently without substantially disrupting their habitat is not always practical or even possible…
population growth rate
TPCs are flexible given variation in food-web context and that trophic interactions may play an important role in shaping TPCs, which are illustrated by this and other studies illustrate the need for a mechanistic model of TPC’s with parameters tied topredation risk.
A semelparous fish continues upstream migration when exposed to alarm cue, but adjusts movement speed and timing
Testing the Threat‐Sensitive Hypothesis with Predator Familiarity and Dietary Specificity
The gradient of observed responses to different snake cues indicates that sirens may be evaluating predation potential of animals based on their foraging specificity and familiarity.
