Short term fluctuations of zooplankton abundance during autumn circulation in two reservoirs with contrasting trophic state

Zooplankton community in the reservoirs of Maranhao and Santa Luzia (Portugal) were studied during the autumn stratification breakdown and the weeks before it. The results from water transparency, chlorophyll-a and total phosphorus concentrations, calanoid to cyclopoid copepods ratio and zooplankton...

The results from water transparency, chlorophyll-a and total phosphorus concentrations, calanoid to cyclopoid copepods ratio and zooplankton abundance confirm the different trophic state of both studied reservoirs: mesotrophic-eutrophic (Maranhao) and oligotrophic-mesotrophic (Santa Luzia), as previous studies have reported. Using Copidodiaptomus numidicus to compare both studied reservoirs, we found higher egg production rates in Maranhao than in Santa Luzia. Nevertheless, no relationship was ever found between zooplankton (abundance or egg production rate) and environmental variables (temperature and chlorophyll-a), which may suggest that wide and complex range of factors, abiotic as much as biotic, are involved in zooplankton dynamics during the autumn circulation period.La comunidad zooplanctónica de los embalses de Maranhao y Santa Luzia (Portugal) fue estudiada durante la ruptura de la estratificación otoñal y las semanas previas. Los resultados de transparencia del agua, concentración de clorofila-a y concentración de fósforo total, así como la razón entre copépodos calanoides y ciclopoides y la abundancia de zooplancton confirman el diferente estado trófico entre ambos embalses: mesotrófico-eutrófico (Maranhao) y oligotrófico-mesotrófico (Santa Luzia), como estudios previos habían mostrado. Utilizando al copépodo Copidodiaptomus numidicus para comparar ambos embalses, se ha observado una mayor tasa de producción de huevos en Maranhao que en Santa Luzia. Sin embargo, en ningún caso se ha encontrado una relación entre el zooplancton (abundancia o tasa de producción de huevos) y las variables ambientales (temperatura y concentración de clorofila-a), por lo que se sugiere que una amplia y compleja gama de factores, tanto bióticos como abióticos, deben de estar involucrados en la dinámica del zooplancton durante el periodo de circulación otoñal. 22009-01-0120092009-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/40156reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengopen accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
