Abstract

We examined the thermal environment of oak-hickory leaf litter at varying depths in the Mill Creek Watershed to better understand the regulation of the structure, diversity, and composition of soil surface-active arthropod communities. We predicted that deep leaf litter would result in cooler, more insulated soil surface temperatures then shallow leaf litter. Leaf litter depth was measured among 100 0.25 m2 quadrats, and we selected plots that represented the median, 10th and 90th percentiles of that range. iButton data loggers were placed on the soil surface of each plot, and left in place for five days, taking temperature recordings hourly on a 24-hour cycle. We plotted our data against ambient temperatures as recorded by an iButton data logger placed on bare soil. Data suggest that thermal environments differ among sites, but this relationship is likely influenced by other environmental factors.
