Microsatellite DNA based analysis of the pattern of genetic diversity among three coastal and five freshwater populations of pikeperch Sander lucioperca in the northern part of the Baltic Sea drainage basin indicated marked genetic differentiation between the coastal and lake populations. The F(st) between these population groups was as high as 0.25 and R(st) =0.32. In general, the lake populat...

The recent introduction of Gracilaria vermiculophylla (Rhodophyta) to the Kiel Fjord area was a reason for concern, since this red macroalga perfoms best under mesohaline conditions and thus appears well adapted to thrive and spread in the Baltic Sea environment. A systematic survey on a coastal range of 500 km in 2006 and 2007 indicated considerable multiplication and spreading of G. vermiculo...

At present, there is no dedicated software platform for the coastal zone remote sensing information extraction. For the complexity of the coastal zone targets which contains shoreline, vegetation and coastal zone types and so on, users can not extract information automatically by computers, so users need operate extraction by comparing to interpreting marks and remote sense images frequently. I...

Coastal wetlands form an important element of the coastal zone natural environment. This paper presents the use of GIS for detecting changes in salt water inflow and for studying the flooding risk due to sea level rise in a micro tidal Beka brackish marsh on the Polish Baltic Coast. Creating a geodatabase within a GIS makes it possible to carry out broad analyses of complex systems, to which co...

Annual rates of N2 fixation were measured over 3 yr (1998–2000) at an open water station (BY31) and 2 coastal stations (H4 and X1) in the Baltic Sea. This is the first report on depthintegrated rates of N2 fixation from more than one complete growth season in the Baltic Sea. Annual estimates of N2 fixation ranged from 56 000 to 125 000 t N in the Baltic Proper, and 18 000 to 162 000 t N at the ...

The implications of the propagation of uncertainty for the e ciency of stochastic water pollution control were analyzed. The empirical analysis focused on nitrogen pollution of the Baltic Sea from Swedish crop farms. A two moment model (mean and variance) of the distribution of coastal load was developed and integrated with an economic model of arable land-use choice. It was shown that uncertai...

Increased precipitation is one projected outcome of climate change that may enhance the discharge of freshwater to the coastal zone. The resulting lower salinity, and associated discharge of both nutrients and dissolved organic carbon, may influence food web functioning. The scope of this study was to determine the net outcome of increased freshwater discharge on the balance between autoand het...
