Abstract

This study was conducted in the Talladega watershed (outlet: 33.7622, -85.5955), located in the Talladega National Forest (Cleburne County, AL) and drains a non-perennial tributary of Pendergrass Creek. Covering 0.92 km² of mixed coniferous and deciduous forest in the Piedmont Upland physiographic section, the watershed ranges in elevation from 345 to 456 m and ultimately drains into the Coosa River (Mobile-Tombigbee basin). The region has a humid subtropical climate with mean January and July temperatures of 5.3°C and 25.3°C, and annual precipitation of 1,400 mm. This watershed was part of a seasonal sampling survey (January 2022–January 2024) for the AIMS Project. Data on hydrology, biogeochemistry, and microbial ecology were collected at 7 sites per watershed. At each site, water (if present), biofilm, leaf litter, and sediment were sampled. Microbial enzyme activities were measured to assess organic matter decomposition (β-glucosidase, phenol oxidase, peroxidase) and nutrient mineralization (N-acetylglucosaminidase for nitrogen, phosphatase for phosphorus) using fluorometric (MUB) and colorimetric (pNP, L-DOPA) assays.
