1. Trophic effects on the maintenance of biodiversity in the Fucus zone
Sammanfattning : Ecologically important macroalgae with large thalli and complex structures are threatened worldwide due to anthropogenic activities such as pollution. In the northern Baltic Sea the salinity is very low; the only large algae producing complex structural habitats found there are the fucoid species Fucus radicans and F. vesiculosus. LÄS MER
2. Man-made structures as habitat for marine faunal assemblages
Sammanfattning : Artificial reefs are structures placed in the sea to promote marine life. Although constructions such as oil-rigs, wind farms, bridges and pier pilings are built for other purposes, they could be regarded as artificial reefs as they add new surfaces in the oceans, susceptible to colonization by marine organism.

3. Neolithic Fisheries : Osteoarchaeology of Fish Remains in the Baltic Sea Region
Sammanfattning : The variety of fish species found at the archaeological sites indicates the exploitation of local and regional ecosystems. The focus of the fisheries varies from site to site. LÄS MER
4. Ecological aspects of soft bottom meiofauna in Eastern Africa
Sammanfattning : The meiobenthos is numerically the most abundant metazoan group in shallow water habitats. While the meiobenthos characteristically shows variable distribution, the causal factors controlling this variation remain poorly understood. LÄS MER
5. Animal husbandry in the Viking Age town of Birka and its hinterland : excavations in the black earth 1990-95
Sammanfattning : The Birka Excavations 1990-95 provided a unique opportunity to excavate a Swedish Viking Age town stratigraphically, allowing the finds - including extensive and well-preserved faunal remains - to be dated accurately. This in turn has given the opportunity to study the nature and development of Viking Age animal husbandry in a new, closer perspective. LÄS MER
