| description | As in other countries, the effects of human stressors on coastal areas and waters in Nigeria are increasing, and management strategies are urgent. In order to assess this, studies on phytoplankton composition in relation to physico- chemical characteristic of two tidal creeks in Lagos were conducted for six months (October 2007 to March 2008). Variations in some of the physical and chemical parameters such as rainfall, temperature, salinity, nitrate-nitrogen, phosphate- phosphorus, sulphate, salinity, biological oxygen demand and chemical oxygen demand influenced the phytoplankton abundance. Three major divisions were recorded for the two creeks: Bacillariophyta, Chlorophyta and Cyanophyta. Among these, diatoms were the most abundant group observed. Water quality characteristics reflected the effect of tidal influence and consequent salt water inflow, fresh water incursion and the pollution status of one of the creeks, as a result of industrial and commercial activities in the area. Rev. Biol. Trop. 58 (3): 827-840. Epub 2010 September 01.<br>Como en otros países, los efectos de actividades antropogénicas en las zonas costeras y las aguas de Nigeria están aumentando, y las estrategias de gestión son urgentes. Durante seis meses (octubre 2007-marzo 2008) se estudió la composición del fitoplancton en relación con las características físico-químicas de dos canales en Lagos, Nigeria. Las variaciones en algunos de los parámetros físicos y químicos tales como precipitación, temperatura, salinidad, nitrato-nitrógeno, fosfato-fósforo, sulfato, salinidad, demanda biológica de oxígeno y demanda química de oxígeno; afectan la abundancia del fitoplancton. En los dos arroyos se registraron tres divisiones principales: Bacillariophyta, Chlorophyta y Cyanophyta, las diatomeas fueron el grupo más abundante observado. Características de calidad del agua reflejan el efecto de la influencia de las mareas y la consiguiente entrada de agua salada, la incursión de agua dulce y el estado de contaminación de uno de los canales, como consecuencia de actividades industriales y comerciales en la zona. |
