Seasonal phytoplanktonic variation in an urban lake from Cuernavaca, Morelos, Mexico

The following investigation took place in the lake Parque Alameda de la Solidaridad in Cuernavaca Morelos. Samples at three sites in the lake were taken to determine the variation and abundance of phytoplankton during the four seasons the year. Temperature, transparency, oxygen, pH and nutrients (ni...

Descrição
Resumo:The following investigation took place in the lake Parque Alameda de la Solidaridad in Cuernavaca Morelos. Samples at three sites in the lake were taken to determine the variation and abundance of phytoplankton during the four seasons the year. Temperature, transparency, oxygen, pH and nutrients (nitrates, amonium and phosphorous) were determined. Thirty species were recognized, the Chlorophyceae were the most abundant and with the higher number of species. The higher abundances of all the period were in spring and winter. Oocystis solitaria and Leptolyngbya sp. were the predominant species with abundances higher than (>1×106 org/ml). The variation of phycoflora in the lake, showed a temporal succession in frequent, seasonal, occasional and rare species. The phytoplankton species richness and abundance, as well nutrients concentrations showed the lake as a hypertrophic system water body.
