Resumen
Se presentan las tendencias como indicadores biológicos de condiciones oceanográficas de 64 organismos seleccionados por su repetitividad en 62 publicaciones que cubren un período de estudio desde 1961 hasta el 2005 realizados a lo largo del mar ecuatoriano y aguas adyacentes. Mediante la recopilación y clasificación por medio de tablas, se establece la tendencia de algunas especies hacia aguas cálidas, otras especies hacia aguas frías, otras hacia aguas de transición y otras por su preferencia hacia aguas oceánicas o neríticas. De las 64 especies seleccionadas del fitoplancton y zooplancton marino, pertenecientes a 32 géneros, se encontraron que 9 especies presentan tendencias
hacia las aguas cálidas y 17 especies presentan tendencias hacia aguas frías; mientras que las 38 especies restantes presentan una mayor tolerancia, pudiendo ser encontradas tanto en aguas frías como en aguas cálidas, por lo que fueron descartadas como indicadoras de condiciones oceanográficas. Las especies consideradas indicadoras de aguas cálidas corresponden a los dinoflagelados. Las especies consideradas indicadoras de aguas frías corresponden a las diatomeas centrales. Merece especial atención el ciliado fotosintetizador Mesodinium rubrum por su fuerte relación con los eventos de mareas rojas ocurrentes en los últimos años en el Ecuador
Trends are presented as biological indicators of oceanographic conditions of 64 organizations selected for their repeatability in 62 publications covering a study period from 1961 to 2005 made along the Ecuadorian sea and adjacent waters. By collecting and sorting through tables, sets the trend toward warm water species, other species into cold waters to other transitional waters and others by their preference for oceanic and neritic waters. Of the 64 species selected marine phytoplankton and zooplankton, belonging to 32 genera, 9 species were found to exhibit trends to the warm waters and 17 species have tendencies toward cold water, while the remaining 38 species exhibit increased tolerance and can be found in both cold water and warm water, so they were discarded as indicators of oceanographic conditions. Considered indicator species are warm-water dinoflagellates. Species considered coldwater indicator correspond to centric diatoms. Especially noteworthy Mesodinium photosynthetic ciliate rubrum by its strong relationship with red tide events occurring in recent years in Ecuador.
