Leaf-litter decomposition of the mangrove species Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle
This study evaluated the decomposition process of leaf litter from the main Brazilian mangrove species Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle. Senescent leaves were collected, dried and placed in nylon bags with different mesh sizes (fine: 2 × 2 mm and coarse: 8 × 8 mm)....
