importance of allochthonous input from the boreal catchments.
The sites used in this study are often natural brownwater
systems, with high contents of humic substances.
We attempted to (1) identify and quantify possible
sources of variation in surface water chemistry of boreal
streams and lakes, (2) determine which environmental
factors and which spatial scales are most important in
determining the surface water chemistry of boreal streams
and lakes, and (3) determine similarities/differences in the
factors driving stream/lake water chemistry.
