dc.description.abstract | The study was carried out from 2007 to
2010 in two ecoregions: the Carpathians and the
Central Highlands. The objectives of our survey were
to test the existing biological index metric based on
benthic macroinvertebrates at reference conditions in
the high- and mid-altitude mountain streams of two
ecoregions according to the requirements of the EU
WFD and to determine which environmental factors
influence the distribution of benthic macroinvertebrates.
Our results revealed statistically significant
differences in the values of the physical and chemical
parameters of water as well as the mean values of
metrics between the types of streams at the sampling
sites. RDA analysis showed that the temperature of the
water, pH, conductivity, the stream gradient, values of
the HQA index, and altitude were the parameters most
associated with the distribution of benthic macroinvertebrate
taxa and the values of the metrics. The
values of biological indices should be considered
according to the stream typology including altitude
and geology. At the reference conditions, the suggested
border values of biological indices are very
harsh. The values of the biological indices of most
sampling sites did not correspond to the requirements
of the high status in rivers. The streams at altitudes
above 1,200 m a.s.l. should be treated as another river
type and new reference values should be established. | pl_PL |
