Description
Summary:Mounded, tallgrass prairie ecosystems are a unique, endangered ecosystem due to severe disturbance for agricultural production and/or urban expansion. Limited research exists on earthworm (Lumbricus terrestris) dynamics in mounded, tallgrass prairies, particularly in the Ozark Highlands region of northwestern Arkansas. The objectives of this study were to evaluate the effects of soil moisture regime (SMR), landscape position (LP), and sample date on earthworm densities in the top 20 cm of soil in two mounded, native prairies in the Ozark Highlands region of northwestern Arkansas. Juvenile and total earthworm densities were five times greater (P
