Abstract
The Coiba National Park is located off the Pacific coast of Panama andincludes several small islands and a larger one which gives its name to the park. Anumber of rivers in Coiba Island have well developed mangrove systems attheir mouths and two of these were selected for the present study: SantaCruz and El Gambute. The first one comprises an assemblage of Rhizopora mangle, Laguncularia racemosa and Pellicierarhizoporae, and shows no evidence of recent human activity. The secondone is a smaller forest, solely composed of short Rhizoporamangle trees, and is recovering from the impact of human activities.During 1997, the tidal flats associated with each system were studied. Toasses the polychaete distribution within each tidal flat, three transects werearranged from the low to the upper intertidal level. Every transect hadthree sampling sites: the first one was adjacent to the low water level, thesecond one at an intermediate point, and the third one close to the highwater level and the mangrove line. At each site, three randomly chosensamples of sediment were taken for faunal study and a further one wascollected for sedimentology study.The polychaetes were identifiedto species or genus level. For each flat, a matrix summarizing the actualnumber of individuals of each species in every sample was created, andpopulation density, species richness and diversity were computed for eachsite. After matrix data had been transformed, a similarity analysis of thesamples was carried out.
