  1. 11. Influence of resuspension on sediment-water solute exchange and particle transport in marine environments

    Författare :Elin Almroth Rosell; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resuspension; benthic fluxes; oxygen; dissolved inorganic carbon; nutrients; dissolved iron and manganese; in situ chambers; benthic lander; organic matter transport; ecological modeling; Gothenburg Archipelago; Gulf of Finland; Baltic Sea; Loch Creran; Scotland;

    Sammanfattning : Marine sediments contain a large pool of nutrients, which if released would contribute to increased eutrophication, in spite of decreased nutrient loads from land and atmosphere. Resuspension is a process, which might influence the release of nutrients from the sediment to the overlying water. LÄS MER

  3. 12. Interactions between natural enemies and the dioecious herb Silene dioica

    Författare :Viktoria Pettersson; Barbara E. Giles; Lars Ericson; Pia Mutikainen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Delia criniventris; Caryocolum viscariella; Microbotryum violaceum; plant-herbivore interactions; plant -pathogen interactions; sex bias; sex rato; successional gradients; fitness effects; Skeppsvik Archipelago; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : About 6% of all angiosperms are dioecious. This separation of sexual function to male and female individuals, and the fundamentally different patterns of reproductive resource allocation that follows that separation, are thought to have important ecological and evolutionary consequences for plant enemy interactions.

  4. 13. Metapopulations dynamics and sex-specific resource allocation in Silene dioica

    Författare :Elisabet Peedu; Pär Ingvarsson; Barbara Giles; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Skeppvik Archipelago; Metapopulation Dynamics; Population Genetic Structuring; Genetic Diversity; Gene Flow; Sex-Specific Resource Allocation; Cost of Reproduction; Life-History Theory; Sexual Dimorphism; Reproductive Effort; biology; biologi; evolutionär genetik; evolutionary genetics; ekologisk botanik; Ecological Botany;

    Sammanfattning : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment.

  5. 14. Studier över önamnen i Luleå skärgård

    Författare :Else Britt Lindblom; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; names of islands; place-names; place-name structure; compounds; place nomenclature; land uplift; uplifted areas; colonization; personal names; önamn; Luleå skärgård; Namnforskning; Name Care and Name Planning; Place Names; Ortnamn;

    Sammanfattning : The aim of this thesis is to present and examine the names of the islands in the archipelago of Luleå innorthern Sweden. The basis for the studies is a collection of names, which contains written forms excerpted from sources from the 14th to the 20th century and local pronunciations of old as well as modern names.
