Leaf-litter decomposition of pioneer plants and detritivore macrofaunal assemblages on coal ash disposals in southern Brazil.

摘要: Abstract We studied the leaf-litter decomposition of three pioneer plants (Cynodon dactylon – grass; Ricinus communis shrub and Schinus terebinthifolius tree), diversity associated detritivore macrofaunal assemblages in a system affected by two coal ash disposals (fly boiler slag) southern Brazil. conducted litter bag experiment area during period 140 days. found that rate R. was more than 80% faster (k-value 20.7) other species. This result agrees with its low C:N ratio, high N (%), increased abundance detritivores first days decomposition. On hand, this supported lowest invertebrate species richness. C. S. leaf-litters were similar rates macrofauna diversity. The type disposal did not affect densities; on morphospecies composition distinct different sites.
