Microarthropods are a size class of detritivores responsible for breaking down organic matter, incorporating it into the soil, and making nutrients available for plant growth. These organisms are ubiquitous in soils all around the globe, have been found to vary in their community structure by region, and enhance decomposition rates in certain climates. However, their relative contribution to decomposition in the face of future climate is still largely unknown. Here we address how microarthropods contribute to decomposition rates across a mountain gradient in response to climate change. The findings of this study suggest that microarthropods significantly enhance decomposition at four ecosystem types along a mountain gradient in Northern Arizona. However, their influence on decomposition does not change in response to a 15-year warming or drying treatment. These results support the notion that soil microarthropods continue to play a fundamental role in the initial stages of decomposition regardless of climate and plant community shifts across an arid-land elevational gradient.
