Litterfall of tropical forested wetlands of Veracruz in the coastal floodplains of the Gulf of Mexico

摘要: Abstract Canopy productivity of five seasonally flooded forests in the central area Gulf Mexico was estimated by measuring litterfall. Productivity on a monthly basis from November 2005 to October 2006, and values ranged between 9 15 t ha−1 yr−1. A total 57 plant species were recorded based litter collected. The dominant (Pachira aquatica, Annona glabra, Hippocratea celastroides Dalbergia brownei) principal litterfall producers. contribution two life forms assessed: trees (including trees, shrubs palms) lianas (climbers, creepers). Lianas found be extremely productive represented 8 62% at sampled locations. Leaves contributed most litter, followed branches reproductive structures. Fruit seed fall coincided with rainy season, accounted for 50–90% production shedding during season. Species that released seeds this time had their dispersed water. Flower occurred dry season (March–June). richness did not explain productivity. these is similar mangrove ecosystems.
