| description | The importance of mangrove systems as a source of income for coastal communities resides in their function as refuges and habitats for a great diversity of aquatic and terrestrial organisms. With the objective of developing a management plan for the Pampa-Murillo lagoon system, a model of the flow of matter inside and emanating from the mangrove was designed. The model was based on records of leaf litter production, herbivory, decomposition of fallen leaves and detritus movement towards the marine zone. Data was gathered from January to October in four types of mangrove forest where Rhizophora mangle, Laguncularia racemosa, Avicennia germinans and Conocarpus erectus species were present. In this system the daily production of leaf litter was 3,9 g/m2, equivalent to 7,9 t C/ha. The major leaf consumption by herbivores was in A. germinans with 13,6 %, followed of L. racemosa (12,5 %), R. mangle (9,8 %), being the lowest in C. erectus (5 ,7 %). The most resistant species to degradation was C. erectus which lost lower than 50 % of the initial organic matter content of its leaves over a period of 210 days. In contrast, A. germinans degraded most quickly retaining only 12,4 % of initial organic matter content after the same period. Of the organic matter produced by the forests, the mangrove system exports the least amount of detritus in May (0,5 t dry weigth/h), whereas detritus movement rises to 1,5 t/h (dry weight) in October. This represents the equivalent of approximately 4 822,2 t C/year, of which 54,5 % is organic matter. This material constitutes an important nutritional input into the adjacent marine zone. |

La importancia de los sistemas de manglar como fuente de ingreso económico para las comunidades humanas reside en la función que desempeñan como refugio y hábitat para una gran diversidad de organismos acuáticos y terrestres. Con el objetivo de contribuir a un plan de manejo en el sistema Lagunar Pampa Murillo se construyó un modelo del flujo de materia dentro y hacia afuera del manglar con base en estudios de producción de hojarasca, herbivoría, degradación de hojas y exportación de detritus hacia la zona marina. De enero a octubre se realizaron los estudios en cuatro especies de mangle: Rhizophora mangle, Laguncularia racemosa, Avicennia germinans y Conocarpus erectus. En este sistema la producción diaria de hojarasca fue 3,9 g/m2, lo que equivale a 7,9 t C/ha, el porcentaje de consumo en peso sobre las hojas realizado por los herbívoros fue de 13,6 % en A. germinans, 12,5 % en L. racemosa, 9,8 % en R. mangle y 5,7 % C. erectus. La especie más resistente a la degradación fue C. erectus, que en 210 días perdió menos de 50 % de la materia orgánica inicial contenida en las hojas; mientras que A. germinans en el mismo tiempo perdió 87,6 % de la materia orgánica. De la productividad del bosque, el sistema exporta 0,5 t de peso seco/hora de detritus en el mes de mayo; mientras en octubre se eleva a 1,5 t/h (peso seco), para un total de 4 822,2 t C/año que salen del sistema con 54,5 % de materia orgánica, constituyendo un subsidio alimenticio para la zona marina adyacente.
