dc.description.abstractDebido a la disminución de los organismos en los arrecifes rocosos y coralinos, es fundamental conocer las poblaciones de organismos propensos a enfermedades marinas, con el propósito de desarrollar predicciones precisas de su superviviencia y a su vez dar la alarma temprana sobre los motivos y las causas de los brotes de las enfermedades.

oaire.objetivesMain Objetives : The major goal of this proposal is to investigate the fungal pathogens and invasive species (Carijoa riisei) affecting gorgonian corals in the Tropical Eastern Pacific (TEP). We will also monitor environmental variables in order to test a correlation between disease prevalence and seawater temperature anomalies. The study of seafan populations will be carried out at Cabo Corrientes, the western most point in the Colombian Pacific, together with Gorgona island and Malpelo island, sites where affected colonies were recently observed and tagged. This project will not only provide timely information on a new area affected by coral diseases but will comprise a unique opportunity to test the direct links between disease outbreaks, invasive species and rising seawater temperatures. Particular goals of the project are.en
oaire.objetivesSpecific Objectives : 1. To isolate the fungal disease pathogens determining the host-range, epizootiology and prevalence of particular fungal assemblages through time in both diseased and healthy colonies in the Colombian TEP.en
oaire.objetivesSpecific Objectives : 2. To monitor disease prevalence at several TEP locations and compared them against environmental variables such as water temperature and sea level. - Currently, we have two possible hypotheses on the present situation. (i) The disease just appeared in the area and susceptible species will be reduced to extinction in a few years; (ii) the disease was due to opportunistic fungal species already in the area, which infects colonies after disturbance, such as rising temperatures or extreme high tides, and recovery is possible if conditions return to normality.en
oaire.objetivesSpecific Objectives : 3. To monitor the invasion of Carijoa riisei and its relationship to octocoral mortality and disease. Disturbances such as elevated seawater temperatures and extreme high tides, with a following high nutrient input, are two likely environmental factors that could lead not only to octocoral disease but also to invasive species superiority. A synergy hypothesis will be tested in this project.en
