Spatial and temporal variability of stable isotopes and biological parameters for the Danube River in Serbia
Апстракт
This paper presents the results of hydrological, physicochemical, biological, and isotopic investigations of the Danube River along the stretch through Serbian territory conducted during four campaigns in September and November 2007, September 2008 and April 2009. The stable isotope values exhibited significant changes both in the Danube (-10.7 to -9.5% for delta(18)O and -73.7 to -67.1% for delta(2)H) and in its tributaries (-9.1 to -8.5% for delta(18)O and -69.4 to -59.4% for delta(2)H) depending on the time of survey, which could be partly attributed to the influences of seasonal effects. Results emphasise the dominant role of tributaries inflows from aquifers along the Danube. The very narrow range of delta(13)C(POC) (from -28.9 to -27.4%) was associated with relatively high C/N ratios (C/N GT 9), and together with delta(15)N(TPN) values, the date suggested that, in early spring, a major fraction of particulate organic matter was derived from allochthonous matter. An orthogonal var...imax rotation of the principal components analysis identified four latent factors (mineral related, biological, hardness, and soil inlets) which are responsible for the data structure covering 79% of the observed variations among the variables studied. A reliable grouping of samples with respect to the season was found.
