Studies were conducted in 2010 on phytoplankton assemblages in ponds in North-East Poland with catchment areas in village environments, mid-forest, mid-meadow and mid-field settings. Differences in phytoplankton abundance, biomass and structure and the environmental requirements of dominant species were assessed in the studied ponds. These features were related to variable physicochemical water parameters and nutrient presence; with the highest phytoplankton abundance and biomass dominated by chlorophytes and diatoms in the village ponds and the greatest diversity of species’ assemblages recorded in the mid-forest and mid-field ponds. In addition, CCA analysis of general trends in phytoplankton growth determined that NH4 and TN enhanced growth in the mid-meadow and mid-field ponds, and P-PO4 and pH influenced growth in the mid-forest pond. The relationships established in this study between phytoplankton and environmental conditions can directly influence future directions in small water-body conservation.
Résumé
Les études ont été menées en 2010 sur des assemblages de phytoplancton dans des mares dans le nord-est de la Pologne avec des bassins versants en milieu villageois, forestier, prairial et cultivé. Des différences dans l'abondance, la biomasse et la structure du phytoplancton et les exigences environnementales des espèces dominantes ont été évaluées dans les mares étudiées. Ces caractéristiques étaient liées aux paramètres physicochimiques variables de l'eau et à la présence de nutriments; avec la plus grande abondance et biomasse de phytoplancton dominée par les chlorophytes et les diatomées dans les mares du village et la plus grande diversité d'assemblages d'espèces enregistrés dans les mares du milieu forestier et cultivé. En outre, l'analyse CCA des tendances générales de la croissance du phytoplancton a déterminé que la croissance accrue par NH4 et TN dans les mares prairiale et en champ cultivé, et que le P-PO4 et le pH ont influencé la croissance dans la mare forestière. Les relations établies dans cette étude entre le phytoplancton et les conditions environnementales peuvent influencer directement les orientations futures dans la conservation des petites mares.
