Diversidad de peces demersales en la plataforma continental del Ecuador

Diversidad de peces demersales en la plataforma continental del Ecuador

Abstract

A partir de información colectada de cuatro cruceros de investigación a bordo del B/l Tohalli, se analiza la diversidad de peces óseos y elasmobranquios presentes en la plataforma continental del Ecuador. Los valores medios de diversidad estimados indican que tanto las poblaciones de peces óseos y condrictios demersales hasta los 120 m de profundidad presenten heterogeneidad, con un grado significativo de organización. Las fluctuaciones en el índice de diversidad en las diferentes subáreas y estratos estarán relacionadas probablemente con la variabilidad climática. Los mínimos observados se deducen como resultado de la dominancia de Raja equatorialis, R. velezi, Pomadasys sp., y Prionotus stephanophrys, así como un descenso en el número de especies presentes. Based on information collected from four research cruises aboard the B /1 Tohalli, the diversity of bony fishes and elasmobranchs in the Ecuador continental shelf is analyzed. The mean values of diversity indicate that both bony fish population and demersal chondrichthyan (120 m of depth) show heterogeneity, with a significant degree of organization. Fluctuations in the diversity index in different subareas and strata are probably related to climate variability. The minimum values observed are deducted as a result of the dominance of Raja equatorialis, R, velezi, Pomadasys sp., and Prionotus stephanophrys, and a decrease in the number of species present as weli.
