Initial Litter Collection and Deployment Litter of C. jamaicense and E. cellulosa were collected at SRS 2. Litter of R. mangle was collected at SRS6. Litter of T. testudinum was collected at TS/Ph10. Collected litter of C. jamaicense, E. cellulosa, and R. mangle were air fried for 2 weeks before being subset into litter bags. Three (3) grams of dry litter was sealed in each coarse (3mm) and fine (1mm) mesh litter bag. Fine mesh litter bags were further sealed inside a corresponding coarse mesh bag. Each bag was marked with a metal tag to identify the specific bag. The exact mass of litter in each coarse and fine mesh bag was recorded before sealing the bags. Collected T. testudinum litter was weighed wet and was collected, weighed, and deployed within 3 days of initial collection, and was maintained at 7 C until being deployed. A subset of T. testudinum litter was weighed and dried and the ratio of wet to dry mass was used to calculate the initial dry mass of each T. testudinum sample. Six (6) grams of wet T. testudinum litter was sealed in each coarse and fine mesh litter bag. Fine mesh litter bags were further sealed inside a corresponding coarse mesh bag. Each bag was marked with a metal tag to identify the specific bag. The exact wet mass of litter in each coarse and fine mesh bag was recorded before sealing the bags.
Litterbag Deployment Litter of C. jamaicense, E. cellulosa, and R. mangle were deployed to all sites (SRS2, SRS4, SRS6, TS/Ph2, TS/Ph3, TS/Ph7, TS/Ph10). Litter of T. testudinum was deployed at SRS6, TS/Ph7, and TS/Ph10.
Litter Retrieval Litterbag replicates were retrieved at 1, 3, and 10 months after deployment. Litter was dried, weighed and combusted to calculate the ash-free dry mass (AFDM) of the remaining litter. The AFDM was used to calculate the total mass loss, and days deployed were used to calculate the breakdown rate k for each litter sample.
