Due to discharge from acid sulfate (a.s.) soils, watercourses and coastal areas in the Gulf of Bothnia are periodically heavily acidified with high concentrations of potentially toxic metals. Data on water quality from 2005 to 2014 in an embanked lak

In order to study anadromous whitefish spawning river requirements, we sampled 41 rivers in the Gulf of Bothnia for newly hatched whitefish larvae for one to three consecutive years. Chemical and m ...

We propose to use Gaussian processes for species distribution modeling. The objectives are to predict the spatial occurrence pattern and to identify the environmental variables that describe the occurrence. Our model combines a non-linear predictor w

The episodic acid runoff from the catchment areas of rivers with sulphide-bearing fine-grained sediments caused recruitment failures of burbot ( Lota lota ) in the Gulf of Bothnia. In the episodically acid river Kyronjoki, emptying into the Gulf of B

The objectives of this study were to determine the effects of acidification on 0+ juvenile fish diversity and abundance in River Kyronjoki in 1995 and 1996. Species diversity and abundance data were obtained from seine hauls in aquatic vegetation bio

The burbot population off the River Kyronjoki has suffered from acidification in its reproduction area, causing a reduction of the population throughout the 1980s. During the same period of time the mean length-at-age of burbot was found to increase,

Variations in the year-class strength of perch (Perca fluviatilis) were analyzed among 23 populations in Baltic coastal areas distributed between 57 and 66°N using the age distribution in catches. In spite of large differences in abiotic and biotic

Several freshwater species use the Kyronjoki River estuary as a spawning and nursery area. The main reasons for this seem to be the morphology of the estuary, the abundance of shelter provided by aquatic macrophytes, high food production and favourab
