Four Finnish and five Swedish populations of Helix pomatia, living at the ecological margin of the species, have been studied electrophoretically. The populations are of different origins, small and completely isolated. However, their polymorphisms a

Several hypotheses have been suggested to account for the adaptive significance of the different wing morphs in water-striders (Gerris, Heteroptera). Stability and isolation of population sites should favour short-wingedness; increased rates of popul

A new variant of factor analysis (positive matrix factorization, PMF) is applied to a Finnish data set (18 years, 15 locations) of monthly bulk wet deposition concentrations of strong acids, SO4, NO3, NH4, total nitrogen (Ntot), total phosphorus (Pto

Concentrations of metals (Cd, Pb, Ni, Cu, Zn, Mn, Al and Fe) were measured in 256 lakes in 1987 as part of a nationwide acidification survey. Concentrations generally followed the pattern of atmospheric deposition observed in snowpack and moss chemis

The study on the effects of acidification and airborne load on the concentrations of some trace metals (Al, Mn, Cd, Cu, Pb, Zn, Ni, Hg) in sediments (16 lakes), water (259 lakes) and aquatic fauna (14 lakes) of pristine Finnish headwater lakes was co

Continuous monitoring of bulk deposition has been made by the Water and Environment Research Institute (WERI) since 1971 in Finland. The results are mainly used in evaluating the deposition to watercourses and soil. The samples have been taken monthl
