| Due to global climate change, lakes in Mediterranean climate face the problem of reduced precipitation and enhanced evaporation along with increased water abstraction for irrigation that are largely causing changes in water level, salinity and nutrient dynamics. In this study 22 Turkish shallow lakes were investigated in the Mediterranean climate zone. All lakes were sampled with a well-established snapshot sampling protocol. There are 19 lakes, which were sampled once during both spring and summer seasons within the same year and 9 lakes that were sampled once during both drought and wet years. Also, data of 1997 - 2012 period from Lake Eymir and Mogan were used to investigate the effects of drought in a longer term period. Environmental data were tested for normality and variables that do not follow normal distribution were transformed. Principal Component Analysis (PCA) was applied to the environmental data, including surface water temperature, salinity, pH, mean air temperature, Secchi depth, alkalinity, total phosphorus, total nitrogen, net evaporation, net precipitation and chlorophyll a (spring – summer) and without total nitrogen (Lake Eymir - Mogan) and additionally number of fish and total zooplankton biomass (for wet – dry years). Lakes sampled during spring seasons were associated with high Secchi and maximum depth, dissolved oxygen and precipitation. So, in spring seasons lakes can be characterized as in a clear water state, whereas lakes sampled in summer seasons were identified with high chlorophyll a, total nitrogen and total phosphorous concentration and salinity. Thus, lakes sampled during summer … |
