Mesozooplankton composition and distribution in relation to oceanographic conditions in the Gulf of Cádiz, Spain.

Two surveys were conducted during July 1994 and July 1995 in the Gulf of Cadiz with the aim of assessing temporal and spatial patterns in biomass (ZDV, zooplankton displacement volume) and mesozooplankton composition and their relationships with the oceanographic conditions. Differences between two...

Ha sido observada variabilidad temporal entre los dos veranos. La columna de agua ha sido más caliente y salina en 1994 y también ha presentado una mayor densidad y biomasa de mesozooplancton. A pesar de estas variaciones temporales la presencia de varias especies planctónicas fueron notablemente regulares. En los dos veranos los cladóceros (Penilia avirostris, Evadne spinifera, Evadne tergestina, Evadne nordmanni, y Podon) fueron el grupo más abundante seguido por los copépodos y apendicularias. La dominación de cladóceros en verano es básicamente debido a la alta abundancia de Penilia avirostis. El estudio de tendencias demostró que la abundancia relativa de copépodos aumentó tras los veranos, aunque este aumento solamente ha sido significativo en las estaciones occidentales, donde es más elevada la influencia del agua Atlántica. La densidad de mesozooplancton y cladóceros demostró una correlación positiva con temperatura y biomasa pero demostró una correlación negativa con salinidad y profundidad. La biomasa y la densidad de copépodos y apendicularias no han presentado correlación con las variables oceanográficas.SI202320232007info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/320393reponame:DIGITAL.CSIC.
