- Estructura y dinámica del manglar del delta del río Ranchería, Caribe colombiano Luisa Fernanda Lema Vélez Jaime Polanía Biología growth mangrove survival litterfall productivity Structure and dynamics of the mangrove forest in the Ranchería river delta, ColombianCaribbean. We registered seedling survival and biomass increase for Rhizophora mangle L., Avicennia germinansL. and Laguncularia racemosa (L.) Gaertn. f., main mangrove species in the Rancheria River delta,Colombia. Only seedlings of R. mangle were found to survive. We also measured maximum rate of litterfall.We estimated annual litterfall through interpolation within an exponential regression performed with maximumand annual litterfall data published in other sources; the value of annual litterfall for the area was estimated tobe 12.9 mgha-1y-1. We found a 7.4 mgha-1y-1 increase in biomass. Litterfall constitutes the larger fraction of the20.2 mgha-1y-1 productivity of this mangrove. We believe this is a very high value for a forest under unfavorablenatural and human conditions, such as high seasonality and continuous use of the forest to feed goats and sheep.We consider that the high productivity is a response to both natural and anthropogenic stress.
