1. A year-round study was conducted in a mesotrophic reservoir to determine the dynamics of zooplankton populations as a function of food availability (edible phytoplankton), nutrient concentration, temperature and hydraulic regime. 2. Rotifer biomass was correlated with soluble reactive phosphorus (SRP) concentration. The abundance of the rotifers Keratella cochlearis and Anuraeopsis fissa wer...

The effects of inorganic nutrients (N, P) enrichment of mesotrophic lake water on changes in bacterial and protistan (heterotrophic nanoflagellates and ciliates) communities compositions were studied in the mesocosm experiment. Phosphorus (PO4(3-)) and nitrogen (NH4+) alone and in combination were added to three types of experimental mesocosms. Mesocosms results suggested that simultaneous addi...

A fertilization experiment was carried out in 3 mesotrophic fens to investigate whether plant growth in these systems is controlled by the availability of N, P or K. The fens are located in an area with high N inputs from precipitation. They are annually mown in the summer to prevent succession to woodland. Above-ground plant biomass increased significantly upon N fertilization in the two 'mid'...

The estimation of the carrying capacity (CC) is a fundamental process in integrated environmental management, policy making, and decision making. Aquaculture has been studied since 1960s to allow production limits aquaculture projects and, hence, their maximum economic performance within sustainable for local environment. One major drawback these approaches that they can provide CC estimates af...

Variations in the physico-chemical characteristics of estuaries, such as surface water salinity and temperature, lead to establishment gradients that are closely related with distribution nutrients suspended sediment. This affects light penetration, which turn influences Chlorophyll-a (Chl-a) concentration primary productivity. We used MODIS imagery identify spatio-temporal patterns sea salinit...
