  2. 11. Palaeoenvironmental changes in the northern boreal zone of Finland: local versus regional drivers

    Author : Shyhrete Shala; Karin H. Helmens; Christian Bigler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeolimnology; Palaeoecology; Biological assemblages; Sediment geochemistry; Regional drivers; Local drivers; Quantitative temperature reconstructions; Transfer-functions; Holocene; MIS 5d-c; Northern boreal zone; NE Finland; kvartärgeologi; Quaternary Geology;

    Abstract : Multiple proxies derived from the Lake Loitsana sediment sequence (NE Finland) are employed to determine the timing of deglaciation, characterise an early Holocene proglacial lake stage and reconstruct Holocene lake development. Local-scale processes causing shifts in biological assemblages are identified and the most likely Holocene mean July air temperature (Tjul) development is assessed. READ MORE

  4. 12. Mosquitoes as a Part of Wetland Biodiversity

    Author : Martina Schäfer; Jacob Höglund; Jan Lundström; Darold Batzer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity patterns; species assemblages; functional groups; constructed wetlands; dytiscids; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. READ MORE

  5. 13. Fish community patterns in Tanzanian mangrove creeks

    Author : Augustine Mwandya; Martin Gullström; Olof Lindén; Stockholms universitet; []
    Keywords : Mangrove ecosystems; fish assemblages; Mugil cephalus; population genetics; spatial and seasonal variability; human disturbance; East Africa; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zooekologi;

    Abstract : Human beings have exploited the biota of mangrove systems for centuries and fish continue to be one of the main products harvested from these habitats. The assumption of mangroves functioning as recruitment areas for juvenile fish from neighbouring habitats such as seagrass beds and coral reefs is a common argument for conservation and management of mangrove ecosystems.

  6. 14. Governing the manifold subject : a praxiography of Swedish HIV treatment

    Author : Jeffrey A. Christensen; Peter Danholt; Linköpings universitet; []
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Swedish HIV treatment; enactment; governing assemblages; the manifold subject; matters of accountability;

    Abstract : This thesis investigates a multiplicity of ways in which the subject of Swedish HIV treatment is enacted. Drawing on my own experiences of living with HIV in Sweden, the thesis articulates a concern with reflexive, performative, and normative dimensions of contemporary governing assemblages, research practices, and medical interventions.

  7. 15. Habitat structure, degradation and management effects on coral reef fish communities

    Author : Saleh A.S. Yahya; Martin Gullström; Sören Nylin; Narriman Jiddawi; Yunus Mgaya; Gunilla Rosenqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish assemblages; climate change; coral degradation; Indian Ocean; patch reefs; coral bleaching; resilience; zoologisk ekologi; Animal Ecology;

    Abstract : Coral reefs are among the most diverse and productive ecosystems on earth, and are critical to the survival of tropical marine ecosystems and sustenance of local human populations. However, coral reefs are quite vulnerable to disturbances, both natural and anthropogenic. READ MORE
