We are working with collaborators in Massachusetts and Maryland on a study to understand climate-change impacts on red backed salamanders. In each of 4 study areas, we have established replicate plots where we are monitoring salamander populations. We will use a combination of natural environmental variation and experimental manipulations to establish climate relationships for each study area and how they vary across the salamanders range. We hope to eventually link this with coarser monitoring of presence and abundance to develop a cross-scale understanding of range-dynamics for this species.
