| The fecundity and population structure of the cockle, Anadara antiquata L., from sandy/muddy intertidal habitats in the intertidal of Ocean Road beach was examined from January to December 2001. A. antiquata is hand harvested, for domestic consumption, mainly by women and children, with the empty shells sold to traders. The sex ratio from combined data of all classes deviates significantly from 1:1 with the ratio of females to males increasing significantly above 41 mm shell length. Hermaphrodites were also observed in this size range indicating a protrandric hermaphrodite situation with males maturing earlier than females. Fecundity increases with an increase in shell length, with a mean of 1,652,000 (+/- 562,000 [or 40%] SE) eggs per female and... |

| Las formaciones coralinas muestran en el lado norte de la Isla Grande en Isla del Tesoro y del Rosario formación de arrecifes de barrera con dominancia de Acropora palmata, Acropora cervicornis y Porites porites hacia la Isla y la formación de praderas de Thalassia testudinum, y sobre ella, zonas de manchas de corales formadas por Diploria, Porites astreoides, Millepora, Agaricia tenuifolia, Sidesrastrea, etc. En algunos lugares se forman pequeños manglares, seguidos por extensas plataformas de Porites porites. |

| This second volume of a guide to integrated coastal zone management opens a new dimension by discussing the processes involved in a more complete and dynamic way than the first, To fulfil1 this requirement, an expanded work group, drawing upon the knowledge of experts in political science, economics, and sociology, devoted over two years of effort (1999 - 2001) to its completion, following a disciplined working method. A dual principle prevailed in the application of this method. On one hand, it prescribed an approach structured as a series of steps, and on the other, it demanded that real situations be brought to light, emphasizing case studies of experience with or analysis of coastal management. |

| Se estudia la vegetación béntica marina en la zona litoral del Parque Nacional Tayrona durante la época de lluvias (octubre-diciembre, 1974), en base a la distribución de 130 especies de algas y 3 de fanerógamas marinas, respecto a tres subzonas litorales: supra, meso e ¡nfraiítoral, y a tres tipos de liabitats determinados por la calidad del sustrato: rocoso, areno-rocoso y areno-fangoso. Analizando el grado de endcmismo en cada habitat se puede considerar al sustrato areno-rocoso como intermedio en su composición floristica- El grado de epifítismo hallado en los diversos habitáis se interpreta como respuesta adaptanva a una mayor o menor restricción en el área de sustrato firme disponible. Mediante un análisis de similaridad (índice de JACCARD) se puede... |

| The spatial and temporal changes of the fish assemblage areas composition at the coastal ecosystem of the western South Atlantic (34 degree -41 degree S) during six springs (1981, 1983, 1994, 1995, 1998 and 1999), were examined. For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the... |
