The Espirito Santo Federal University lagoon is an artificial environment, created for landscape harmony, although, during some years, it has received domestic effluent in natura from surrounding constructions of the proper campus. The present study aims at evaluating the structure of the phytoplankton community and relating it with some physical and chemical variables of the water and climatological variables of the region, in a sampling station, during eight months (October/2001 to May/2002), in monthly intervals. The phytoplankton was evaluated through its main attributes (richness, dominance, abundance and frequency of occurrence of species, population density, diversity and eveness). The determined environmental variables were: pH, dissolved oxygen, electric conductivity, salinity, turbity, transparency, eufotic zone, depth of the water column, precipitation, and temperature (air and water). To test the significance it enters the phytoplankton's biological variables and the environmental variables and its command the Spearman's correlation coefficient and the ACID was used, respectively. The phytoplankton was composed by 34 taxa, distributed in four class. The predominant classes, qualitatively, was Chlorophyceae, followed of Cyanophyceae and Bacillariophyceae, being less representative the Dinophyceae class. The Chlorophyceae class predominated quantitatively, represented only for the Chlorococcales Order. Cyanophyceae and Bacillariophyceae had presented temporal fluctuations of its respective densities associates to the temperature of the water. The precipitation, the transparencyt and the temperature of the water had been the environmental variables that had more influenced in the structure of phytoplankton of the UFES lagoon, evidencing temporal variation of the community shown for the ACP.

Sequence analysis of the src type of protein kinases revealed that the amino-te...
