    Nyckelord :HUMANIORA; HUMANITIES; social territory; local band; regional band; language family; settlement pattern; semi-sedentary; late mesolithic; neolithic; semi-subterranean house; winter sites; red slate; pit-falls; cooking pits; scrapers;

    Sammanfattning : The main archaeological features studied in this thesis are semi-subterranean house remains in the woodlands of middle northern Sweden, east of the high mountains and some 100 km from the coast. The period during which they were occupied has been delimited to 4500-2500 BC. LÄS MER

  4. 3. Exploring the resilience in coral reefs

    Författare :Jerker Lokrantz; Magnus Nyström; Morgan Pratchett; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coral Reefs; Resilience; Functional Groups; Vulnerability; Overfishing; Ecosystem Indicators; Tanzania; Zanzibar; Marine ecology; Marin ekologi; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Considering the unprecedented global decline of coral reefs concerns about their future existence are well-justified. Safeguarding ecological resilience (i.e. the capacity of ecosystems to absorb disturbance without changing their identity) has become a prime goal for management in order to combat further degradation of coral reefs.

  5. 4. Palaeobiology and Chemostratigraphy of the Precambrian - Cambrian Transitional Beds on the Siberian Platform

    Författare :Artem Kouchinsky; N.J. Butterfield; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

    Sammanfattning : Biological innovations during the Precambrian-Cambrian transition opened evolutionary gates towards the modem biosphere. Two interrelated aspects of this process are investigated. The first one is the ecological radiation and beginning of calcareous biomineralization in mollusc-like organisms (shelled molluscs, coeloscleritophorans, and hyoliths). LÄS MER
