Fertilidad y fecundidad de Montastraea annularis en un arrecifes degradado
Provedor de dados: 20
Autores: Alvarado-Ch., E.; Acosta, A.
Este estudio determinó el ciclo gametogénico, fecundidad y fertilidad de Montastraea annularis en el arrecife de isla Grande, archipiélago de Nuestra Señora del Rosario, uno de los arrecifes más degradados del Caribe colombiano. La población de estudio se caracteriza por poseer colonias medianas (alrededor de 3379 cm2), con mortalidad parcial en 27 % de los ramets y totoal en el 10 % de los mismos. Las colonias presentan un alto número de ramets pequeños producto de la fisión (76 % menores a 50 cm2). Basado en las características de la estructura de tallas de la población mencionada, el objetivo de esta investigación fue explicar el bajo reclutamiento registrado en la zona, a través de la respuesta reproductiva de una población con dominancia de ramets...

Cambio temporal en la estructura de la comunidad coralina del área de Santa Marta - Parque Nacional Natural Tayrona (Caribe colombiano)
Provedor de dados: 20
Autores: Martínez, S.; Acosta, A.
Several predictions have been made, about magnitude and direction of temporal changes in the coral community structure, during the last decade. However, few studies have demonstrated it quantitatively. In order to document such changes, the coral community structure was studied in four continental reefs in the Colombian Caribbean, two in the Santa Marta region: Punta Betín (PB) and Morro Grande Island (MO), and two in the Tayrona National Natural Park (PNNT): Granate cove (GR) and Gayraca bay (GA). Coral composition and cover were quantified in 2002 and compared to base line studies from 1989 (PB, MO &amp; GR) and from 1992 (GA). These variables were quantified by 20 m linear transects between 1.5 m and 29 m depth. After a decade, all reefs lost in average...

Estudio de los procesos relacionados con la presencia de plaguicidas organoclorados en la Ciénaga Grande de Santa Marta
Provedor de dados: 20
Autores: Betancourt, J.M.; Ramírez-Triana, G.
The aim of this paper is to have an approach to the phenomena that take place in the lagoon complex of the Ciénaga Grande de Santa Marta (CGSM), which are related to the behavior of the remaining organochloride pesticides. Besides discussing the depuration processes, precipitation/sedimentation and the damping that are present in this coastal lagoon; with an environmental managing scope. The results analyzed were those obtained from the project called “Monitoring of the environmental conditions and the structural and functional changes of the vegetal communities and fishing resources during the rehabilitation of the CGSM”. The main removal type in the CGSM water system for organochloride compounds in the water column, occurs by  recipitation/sedimentation...
