“…one that is not biased by an overbalance of shallow or deep lakes. Since the majority of the lakes considered in previous studies are shallow (Chambers and Kalff, 1985;Canfield et al, 1985), even those in large datasets (Middelboe and Markager, 1997;Caffrey et al, 2007;Søndergaard et al, 2013), the linear dependence of Zc on SD may have been overestimated. Indeed, few authors have suggested that the relationship between SD and Zc may not be linear.…”

“…In summer the rise in temperature enhances the microbial activity which consequently results in the increase of diffusion process of P from the sediments to the overlying water column [71,72]. Besides diffusion process, change in pH and internal loading from sediments are considered to be the other plausible reasons [22,[73][74][75][76][77]. Still further, seasonal variations in phytoplankton productivity are the other factors ascribed for higher peaks of P [78,79].…”

“…In recent past three to four decades majority of the wetlands have undergone gradual to exhaustive eutrophication, mainly through human intervention, agricultural runoff and waste water from the catchment, causing degradation of both physical as well as biological systems [15][16][17][18]. Shallow inland lakes, particularly susceptible to eutrophication because their productivity can respond rapidly to nutrient enrichment and even reduction in external P loading; often fail to improve water quality because of internal P regeneration from the sediments [19][20][21][22]. In freshwater ecosystems the source of nutrients is generally from organic matter of plants that undergo mineralization and atmospheric nitrogen fixed by aquatic plants and P as associated with apatite bearing minerals [23,24].…”

Hokersar wetland suffers highly due by nutrient inputs from the catchment area, internal wetland processes and various types of anthropogenic pressures around. To characterize nutrient dynamics of the wetland, nitrogen (N) and phosphorus (P) samples were collected from six study sites in the Queen wetland of Kashmir Himalaya for a period of one year from Sep. 2012 to Aug. 2013. Clear spatial and temporal variations were observed among the recorded parameters (ammonical nitrogen, nitrate nitrogen, total orthophosphate phosphorus and total phosphorus) throughout the year. Ammonical nitrogen concentration was found to be maximum in winter (242.3±10.1 µg/L). Lower nitrate nitrogen was observed in summer, recording 259.6±35.3 µg/L. Both the forms of phosphorus registered higher values in summer and lower values in winter. Scatter plot showed highly significant values among all the parameters (R²=0.748 and 0.719). Principal component analysis showed highest principle component vector displacement among the sites IV and VI reflecting polluted nature of the sites. Further, higher Eigen-vector displacement values were due to ammonical nitrogen and nitrate nitrogen, registering values 3.36724 and 0.542639 respectively. Similarity matrix was highest between total phosphorus and ammonical nitrogen (92.9666%), followed by ammonical nitrogen and nitrate nitrogen making 58.5729%.

“…Similarly, for macrophytes, the order of metrics from the best to the worst are ICM, Ellenberg index and C max , although for the latter only the regression coefficient and not the slope could be compared (see Søndergaard et al, 2012 for more info). For fish, the Nordic Index (NLFI) performed considerably better than the European Index (ELFI).…”

Data on phytoplankton, macrophytes, benthic invertebrates and fish from more than 2000 lakes in 22 European countries were used to develop and test metrics for assessing the ecological status of European lakes as required by the Water Framework Directive. The strongest and most sensitive of the 11 metrics responding to eutrophication pressure were phytoplankton chlorophyll a, a taxonomic composition trophic index and a functional traits index, the macrophyte intercalibration taxonomic composition metric and a Nordic lake fish index. Intermediate response was found for a cyanobacterial bloom intensity index (Cyano), the Ellenberg macrophyte index and a multimetric index for benthic invertebrates. The latter also responded to hydromorphological pressure. The metrics provide information on primary and secondary impacts of eutrophication in the pelagic and the littoral zone of lakes. Several of these metrics were used as common metrics in the intercalibration of national assessment systems or have been incorporated directly into the national systems. New biological metrics have been developed Hydrobiologia (2013) 704:57-74 DOI 10.1007/s10750-012-1436 to assess hydromorphological pressures, based on aquatic macrophyte responses to water level fluctuations, and on macroinvertebrate responses to morphological modifications of lake shorelines. These metrics thus enable the quantification of biological impacts of hydromorphological pressures in lakes.
