11. Effects of morphometric isolation and vegetation on the macroinvertebrate community in shallow Baltic Sea land-uplift bays
Abstract : Shallow sheltered Baltic Sea bays are ecologically important habitats that harbour a unique vegetation community and constitute vital reproduction areas for many coastal fish species. Knowledge about the invertebrate community in these bays is, however, limited. READ MORE

12. Genetic variation and local adaptation in peripheral populations of toads
Abstract : Northern fringe populations generally have low amounts of genetic variation and inhabit habitats where specific adaptations are needed. On the Swedish west coast, the natterjack toad (Bufo calamita) inhabits skerry islands. READ MORE

14. Cretaceous palynofloras from southern Scandinavia
Abstract : A palynological investigation of Cretaceous sequences from Höllviken 2, Svedala 1 and Norrevång 1 wells of Scania, Southern Sweden, and from the Arnager Greensand-Arnager Limestone transition on the island of Bornholm, Denmark, was conducted. Well preserved palynofloras were found in strata consisting of shaly mudstones, glauconitic sandstones (greensand) and limestone. READ MORE

15. Late Weichselian and early Holocene changes of vegetation, climate and sea level on the Skagi peninsula, northern Iceland
Abstract : Sediment sequences from five lakes on the Skagi peninsula, northern Iceland, were subjected to mineral magnetic analysis, carbon analysis, pollen analysis, plant macrofossil analysis, diatom analysis, radiocarbon dating and tephra analysis in order to make detailed reconstructions of vegetation, climate and sea level during the Late Weichselian and Early Holocene. The main purpose was to investigate if the dramatic deglacial climatic shifts recorded in proxy records from the North Atlantic region, such as ice cores, marine sediments and lake sediments, also are registered in Skagi lake sediments, which would be expected considering Iceland´s position in the middle of the North Atlantic Ocean, within the range of the Late Weichselian–Early Holocene migrations of the marine polar front.
