Can seasonal variation in fen water chemistry influence the reliability of vegetation-environment analyses?

Popis výsledku v původním jazyce

Temporal variation in fen water chemistry was studied in the Western Carpathian flysch zone (Czech Republic and Slovakia). Ten sites representing particular spring-fen types (tufa-forming fens, rich fens, spring-fen meadows, rich Sphagnum-fens, poor Sphagnum-fens) were studied. Water chemistry was determined three times a year (spring, summer, autumn) for 3 years. Water pH and conductivity were the most stable of the measured variables. Na+, K+, Ca2+ and SO42- were also relatively stable. In contrast, N-NO3-, Cl-, Fe, PO43- and redox-potential temporally varied. These fluctuating, unstable variables explained very little or insignificant amounts of the variation in plant species data in our study area, possibly because of their instability. Further, seasonal variation in physical-chemical properties of the water confounded associations with vegetation types when data from different seasons was used. The significance of the differences among vegetation types (between-subject effect in R
