Resumen
El aumento de la temperatura de los
océanos y el cambio de sus características
químicas, consecuencia del impacto humano,
son las mayores amenazas para los arrecifes
de coral. Estos ecosistemas proveen alimento,
protegen de tsunamis e inundaciones y
generan ingresos para el turismo y la pesca; de
ahí la importancia de su conservación.
Entre 1982 y 1983 se reportó, en el Caribe
de Costa Rica, una alta mortalidad de las
especies de corales suaves llamados abanicos
de mar (Gorgonia flabellum); las causas no
estuvieron muy claras, pero se sospechó
de un agente infeccioso. Años más tarde,
en otros países del Caribe, las poblaciones
disminuyeron debido a un hongo (Aspergillus
sydowii), muy común durante episodios de
altas temperaturas marinas.
Entre 2015 y 2016 el Laboratorio
de Micología de la Escuela de Medicina
Veterinaria de la Universidad Nacional
(EMV-UNA) realizó un estudio, a cargo de la
microbióloga Andrea Urbina y la veterinaria
Alejandra Calderón, con el apoyo de los
biólogos marinos Jorge Cortés, Christian
Mora y Cindy Fernández, del Centro
de Investigación en Ciencias del Mar y
Limnología de la Universidad de Costa
Rica (CIMAR-UCR). El objetivo consistió en
identificar si la enfermedad (aspergilosis)
reportada en el Caribe afectaba a los corales
suaves de nuestro país y buscar lesiones en
estos invertebrados.
Rising ocean temperatures and changing ocean chemistry as a result of human impact are the greatest threats to coral reefs. These ecosystems provide food, protection from tsunamis and floods, and generate income for tourism and fishing; hence the importance of their conservation. Between 1982 and 1983, high mortality of the soft coral species called sea fans (Gorgonia flabellum) was reported in the Caribbean of Costa Rica; the causes were not very clear, but an infectious agent was suspected. Years later, in other Caribbean countries, populations declined due to a fungus (Aspergillus sydowii), very common during episodes of high sea temperatures. Between 2015 and 2016, the Mycology Laboratory of the School of Veterinary Medicine of the National University (EMV-UNA) conducted a study, led by microbiologist Andrea Urbina and veterinarian Alejandra Calderón, with the support of marine biologists Jorge Cortés, Christian Mora and Cindy Fernández, from the Center for Research in Marine Sciences and Limnology of the University of Costa Rica (CIMAR-UCR). The objective was to identify if the disease (aspergillosis) reported in the Caribbean affected soft corals in our country and to look for lesions in these invertebrates.
