Última Structural and compositional dynamics of macroinvertebrates and their relation to environmental variables in Buenaventura Bay Boletín de Investigaciones Gamboa-García,Diego Esteban; Duque,Guillermo; Cogua,Pilar. ABSTRACT Buenaventura bay is characterized by a great dynamic of environmental variables. There is descriptive information concerning the distribution of macroinvertebrates in the bay and its habitat, however it is necessary to document on its dynamics in relation to environmental variables. The objective of the present work was to determine the espatio-temporal variation in the structure and composition of macroinvertebrates and their relationship with the environmental variables. Four sampling (April-June-September November) were carried out throughout 2015, in four stations (Estuary River-Internal Estuary-External Estuary-Marine Estuary). At each station three samples of sediments, physicochemical variables of the water and macroinvertebrates were...

En Colombia, la bahía de Cartagena es uno de los ecosistemas costeros más influenciados por la contaminación con mercurio (Hg). Con el propósito de identificar el estado ambiental de la bahía de Cartagena, en este estudio se determinó metilmercurio (MeHg) y mercurio total (HgT) en sedimentos superficiales y seston, durante cinco muestreos (febrero, abril, junio, julio y octubre), en cinco estaciones (Zona Industrial, Frente al Dique, Centro, Boca Chica y Tierra Bomba), dentro de la bahía, durante 2006. Los resultados señalan que el promedio de HgT en los sedimentos fue 0.18 ± 0.01 µg/g p.s y en seston fue 0.16 ± 0.002 µg/g p.s. En ambos casos el 10% corresponde a MeHg. Se encontró una correlación entre HgT y MeHg en sedimentos (r = 0.87, p < 0.0001) y...

Cartagena Bay is a highly productive habitat which supports important aquatic communities and is considered an estuarine environment. During the sampling season, five commercial fish were captured: ladyfish (Elops smithi), machuelo (Opisthonema oglinum), mullet (Mugil incilis), sea bass (Centropomus ensiferus), and corvina (Cynoscion jamaicensis), all which stomach contents were analyzed. From all the fish captured, 82.6% presented contents in their stomachs, which were separated into 57 items, such as benthic microalgae, dinoflagellates, cyanophytes, sponges, mollusks, annelids, crustaceans, and fish. According to the Importance Relative Index (IRI), E. smithi, C. ensiferus, and C. jamaicensis were classified as third order consumers, O. oglinum as a...
