| description | The aim of this study was to determine the phytoplanktonic groups present at the Betania Reservoir (Yaguará – Huila, Colombia) and to relate them with periods, method and sampling field (Van Dorn Bottles - Direct Method), and sampling sub-reservoirs (Yaguará – Magdalena, Colombia). Two samples were taken: one from 24/03/2013 to 31/03/2013; and the other from 15/06/2013 to 22/06/2013, representing two hydrologic periods. Each of the samples was fixed in Lugol and Transeau solutions, adding 1ml for each 100ml of sample, and 100ml for each 100ml of sample, respectively. The approach taken to determine functional groups was the Morphology-Based Functional Groups (MBFG) by Reynolds and Kruk. Statistics were calculated with RWizard Software using R packages. The results show a total of 28 species classified into 10 taxonomic groups. In most cases, the abundance obtained through both methods was similar. However, there are genus whose abundance was different depending on the sampling method employed. Often there were greater abundances of the genus Ceratium with the Van Dorn Bottles, and also discrepancies for Melosira and Peridinium. During period 1, there was greater presence of Mucilage functional group (total of 42). During period 2, there was greater presence of Mucilage and Silica functional group (total of 47 for each of them). To conclude, there are no significant differences in the functional groups ratios according to the sampling method used, nor related to places or sampling periods, though there are significant differences in the functional groups ratios among sub-reservoirs. Therefore, it is necessary to differentiate among sub-reservoirs, when making subsequent analyses with frecuencies in sampling fields and periods. |
