| En los sedimentos superficiales aledaños al manglar, de cuatro estaciones dentro de la Ciénaga Grande de Santa Marta y una estación en la Bahía de Chengue, se analizaron las concentraciones de seis residuos de plaguicidas organoclorados (lindano, heptacloro, aldrin, pp'DDE, pp'DDD y pp'DDT), mediante la técnica de cromatografía gas-líquido. Se realizaron muestreos trimestrales entre marzo y diciembre de 1993, tratando de abarcar las principales épocas climáticas de la región (seca, lluviosa menor, seca menor y lluviosa mayor). Mediante análisis de varianza multifactorial se encontraron diferencias significativas solamente en las concentraciones de lindano, heptacloro y pp'DDE, entre las diferentes épocas climática; los otros tres compuestos (aldrin, pp'DDD... |

| In this work, we describe qualitative and quantitative aspects of the cycling of detritus of aquatic macrophytes and carbohydrates in two coastal lagoons of the northeastern part of the State of Rio de Janeiro. Samples of water of the Imboassica and Cabiúnas lagoons were enriched with sucrose. Samples of water of the Cabiúnas lagoon were also utilized to arrange mineralization chambers with fragments of three species of aquatic macrophytes found in these lagoons (Typha domingensis, Potamogeton stenostachys and Nymphaea ampla). Following that, the bottles were aerated and incubated (in the laboratory) for a period of 8 days. The concentrations of dissolved oxygen, the pH, the electrical conductivity and the temperature were daily measured. The anaerobic... |

| The natural conservation of coastal lagoons is important not only for their ecological importance, but also because of the valuable ecosystem services they provide for human welfare and wellbeing. Coastal lagoons are shallow semi-enclosed systems that support important habitats such as wetlands, mangroves, salt-marshes and seagrass meadows, as well as a rich biodiversity. Coastal lagoons are also complex social-ecological systems and the ecosystem services that lagoons deliver provide livelihoods, benefits wellbeing and welfare to humans. This study assessed, quantified and valued the ecosystem services of 32 coastal lagoons. The main findings of the study were: (i) the definitions of ecosystem services are still not generally accepted; (ii) the... |

| Se presenta un diagnóstico sobre la calidad ambiental de la laguna costera El Doctor a partir de las principales variables físico químicas y microbiológicas indicadoras de la contaminación orgánica, su estado trófico e higiénico sanitario en tres campañas de muestreo realizadas en febrero de 2006 y mayo y octubre de 2007. La laguna presenta un alto grado de contaminación orgánica, altos valores de nutrientes, así como, elevadas concentraciones de coliformes totales y fecales, y estreptococos fecales, los cuales, sobrepasan los limites establecidos en las normas cubanas de calidad de agua para usos pesquero y recreativo (NC: 22-99 y NC: 25-99). La principal causa de la contaminación de la laguna son los residuales crudos que llegan a la laguna originados... |

| ABSTRACT Coastal lagoons are a focus of primary production and a refuge for biodiversity due to their relative confinement and low depth. La Escollera is a human-made coastal lagoon in El Rodadero, Santa Marta (Colombian Caribbean), excavated in the early 1980s to hold a marina and its fringes planted with mangroves. To generate a baseline of physical variables that contribute to the nderstanding of water circulation and its influence on ecosystem attributes, salinity, temperature, sea level and light penetration data are outinely obtained through electronic recorders and handheld sensors. Salinity and temperature data from January 2017 to February 2018 ollowed the seasonal pattern of the open sea in the Santa Marta area, alternating between lower... |

| Lagoons are highly productive coastal features that provide a range of natural services that society values. Their setting within the coastal landscape leaves them especially vulnerable to profound physical, ecological, and associated societal disturbance from global climate change. Expected shifts in physical and ecological characteristics range from changes in flushing regime, freshwater inputs, and water chemistry to complete inundation and loss and the concomitant loss of natural and human communities. Therefore, managing coastal lagoons in the context of global climate change is critical. Although management approaches will vary depending on local conditions and cultural norms, all management scenarios will need to be nimble and to make full use of... |

| Platanichthys platana is considered a constant species in both Cabiúnas and Imboassica lagoons that are characterised by different marine and freshwater inputs, and anthropogenic influences. The stomach content analysis of P. platana captured between July 1991 and July 1993 revealed filamentous algae, detritus, eggs of benthic invertebrates, larvae of chironomids and bivalves as the main food sources in Imboassica lagoon. Small-sized cladocerans, copepods and shrimp larvae were the prevailing items in Cabiúnas lagoon. Seasonal food variations were noted for the fishes of Imboassica lagoon. Diet differences were highlighted within specimens lesser than 40 mm standard length in Imboassica lagoon, and were related to the increase of marine influence due to... |

| Durante 1994 el chivo mapalé (Cathorops spixii) fue el segundo recurso pesquero más abundante en la Ciénaga Grande de Santa Marta y el Complejo de Pajarales, principal sistema laguno-estuarino de Colombia. A partir de estadísticas de capturas comerciales y prospecciones pesqueras, se determinaron los parámetros básicos de su población: ciclo reproductivo, crecimiento, mortalidad, rendimiento y biomasa por recluta. Se presentaron individuos maduros durante todo el año con un pico de maduración y desove de junio a agosto cubriendo las épocas de lluvia menor y seca, respectivamente. La talla media de madurez se estimó en 23 cm. Los parámetros de crecimiento de la función de von Bertalanffy fueron: L¥ = 32.5 cm y K = 0.38 año-1, en tanto que el índice de... |

| In order to evaluate the structure of the fish community in the coastal lagoon of Mallorquín, sampling was made each two weeks in nine stations widely allocated in the study area from July 1998 to April 1999. A total of 36 species corresponding to 22 fish families were analized. Based on the frequency of occurrence, 58% were classified as occasional visitors, 26% as frequent visitors, and a 16% as residents. Total abundance was 2424 individuals and 187 Kg of biomass (fresh weight). 89,3% of total abundance and the 89,6% of total biomass was represented by four families (Mugilidae, Engraulidae, Gerreidae and Ariidae. Four species (Mugil incilis, Cetengraulis edentulus, Diapterus rhombeus and Eugerres plumieri), included in three families, were dominant,... |
