   Author : Sonja Råberg; Lena Kautsky; Christer Brönmark; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; epiphytes; eutrophication; faunal assemblage; filamentous algae; Fucus radicans; Fucus vesiculosus; grazers; nutrient supply; Marine ecology; Marin ekologi; Plant Ecology; växtekologi;

   Abstract : 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. READ MORE

6. 4. Ecological aspects of soft bottom meiofauna in Eastern Africa

   Author : Simon Ndaro; Magda Vincx; Stockholms universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; zoologi; Zoology;

   Abstract : 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. READ MORE

7. 5. Animal husbandry in the Viking Age town of Birka and its hinterland : excavations in the black earth 1990-95

   Abstract : 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. READ MORE
