Characterisation of the crab Neosarmatium meinerti de Man (Decapoda: Sesarminae) predation on Avicennia marina propagules

摘要: Mangrove forests are essential for coastal and reef protection. It is an ecosystem providing protection from sedimentation a range of goods utilities local population (Walters et al., 2008). Avicennia marina pioneering mangrove species. This tree plays important role in the colonization recolonization mangroves (Osborn Beriak., 1997) as it one first species to settle unforested deforested areas (loc. cit.). Neosarmatium meinerti herbivorous crab, feeding essentially leaves fallen on ground propagules (DahdouhGuebas 1997). The propagule predation has direct impact regeneration (Bosire 2005) therefore their dynamics. In this perspective we intend characterize assess its forest dynamics especially marina. We focus time amount predated upon interactions amongst predators during feeding.
