Red-Backed Salamanders (Plethodon cinereus) are lungless amphibians that rely on their skin for respiration and temperature regulation. Because of this, they prefer cool, moist forest floors and are highly sensitive to heat, drought, and sudden disturbances. In eastern U.S. forests, they make up a significant portion of forest floor biomass, and their sensitivity to environmental changes makes them strong indicators of ecological health. Forest fragmentation alters landscapes by creating more “edges,” which can dramatically change microhabitats. Currently, half of all forests globally are within 500 meters of an edge. As fragmentation increases, studying its effects becomes critical for understanding how forest ecosystems will continue to shift. Harvard Forest’s Climate and Forest Fragmentation (CLIFF) site investigates these changes through various lenses. My project will focus on Red-Backed Salamanders' dispersal and changes throughout the research period at the CLIFF site to understand how Salamanders are adapting to fragmented areas under changing climate conditions. The CLIFF site includes three treatments—drying, control, and wetting—each replicated twice for a total of six plots. A forest clearing was created on the south-facing side of all plots to simulate edge effects and allow assessment of salamander responses to both edge and interior conditions. In each plot, two 60-meter transects were laid out, each with six cover boards placed 7 meters apart (totaling 72). Boards 1–2 lie in heavily fragmented areas, 3–4 in moderately fragmented zones, and 5–6 in the forest interior. My study will assess Salamander weight, body length, life stage, abundance, and distribution across these zones and treatments. Microclimate data (e.g., temperature, humidity, soil conditions) will also be analyzed. I hypothesized that throughout the research period the average weight of the Salamanders will go down, the abundance of the Salamanders will decrease as a whole due to the hotter and drier climate, and we are more likely to see a shift to locating Salamanders mostly in boards in the interior of the forest that are also given the wetting treatment. Data analysis will be done in R on RStudio using one-way ANOVA and generalized linear regression models in R. Given the rapid pace of forest degradation, understanding how an ecologically vital species like the Red-Backed Salamander responds to these pressures is essential for predicting future forest dynamics.
