| contents | Efecto de la turbidez en la productividad primaria en dos estaciones en el Area del Delta del Río Colorado Gabriela De la Pefña Nettel Roberto Millan Niñez Eduardo Santamaría del Ángel Ciencias de la Tierra high turbidity coastal lagoons primary productivity attenuation coefficient Most coastal lagoons that present high tide intervals and high turbulent kinetic energy have highturbidity and, therefore, light is a limiting factor for primary productivity. The Colorado River Deltahas been reported with high turbidity values. Our purpose is to estimate the effect of turbidity on primaryproductivity. We took water samples from two locations within the Colorado River Delta (oneturbid and another less turbid). We carried out daily experiments on primary productivity with the 14Ctechnique during spring and neap tides, from I5 to 22 May, I99 I. We used artificial light incubatorswith lamps of cool white constant light with 66.33 uE m-* s- of irradiance and another with a stroboscopiclamp with white xenon light with 66.17 uE mm2 s- of irradiance. In general, in the samplesfrom the high turbid location we found a higher concentration of chlorophyll a and a higher concentrationof chlorophyll a per cell. In the incubations with the stroboscopic lamp, the samples from the turbid station showed higher assimilation rates and assimilation rates per cell than the samples fromthe clear station. Meanwhile, for the samples from the clear station, the assimilation rates and assimilationrates per cell were higher in the incubations with constant light. 1996 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48022407 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.4 Vol.22 |
