Abstract/Contents:"Soil mesofauna, such as collembola and mites, are important decomposers across many ecosystems. In lawns, soil mesofauna have been implicated in the decomposition of thatch, an unsightly and problematic byproduct of management found in many turfgrasses. We utilize a model lawn mesocosm experiment and a ubiquitous soil mesofauna (Collembola: Isotomidae) to understand their role in thatch decomposition under a variety of simulated lawn management conditions. We hypothesized that the presence of collembola would stimulate microbial activity in thatch and enhance thatch decomposition. We also hypothesized that clipping additions made through mowing would moderate and potentially diminish the role of collembola in thatch decomposition. Finally, we hypothesized that regardless of collembola presence, clipping surface area and addition frequency would positively influence microbial activity and thatch decomposition. Our results indicate that collembola enhance thatch decomposition through their stimulation of microbial activity and biomass accrual, and that the presence of high surface area clippings amenable to microbial utilization may diminish the role of collembola in decomposition and may even suppress thatch decomposition regardless of collembola presence. Our study highlights the nuanced effects of soil mesofauna in enhancing thatch decomposition and suggests that management decisions related to lawn mowing may be equally important to mitigate thatch in lawns."
