  1. 1. Seagrasses and Eutrophication : Interactions between seagrass photosynthesis, epiphytes, macroalgae and mussels

    Författare :Esther Francis Mvungi; Mats Björk; Thomas J. Lyimo; Jens Borum; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2; epiphytes; eutrophication; mussels; pH; Photosynthetic activities; seagrasses; Ulva; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows are highly productive, ecologically and economically valuable ecosystems. However, increased human activities along the coastal areas leading to processes such as eutrophication have resulted in the rapid loss and deterioration of seagrass ecosystems worldwide. LÄS MER

  3. 2. Development and application of a proteomic approach to the assessment of pollution in the marine environment

    Författare :Itxaso Apraiz Larrucea; Susana Cristobal; Joe de Pierre; David Sheehan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; mussels; peroxisomes; two-dimensional electrophoresis 2-DE ; difference gel electrophoresis DIGE ; bisphenol A BPA ; diallyl phthalate DAP ; 2; 2′; 4; 4′-tetrabromodiphenyl ether PBDE-47 ; fuel oil; Prestige oil spill; Environmental toxicology; Miljötoxikologi; Toxicology; Toxikologi; Biochemistry; biokemi;

    Sammanfattning : Today, assessment of the health of coastal waters is recognized as being important for both the conservation of nature and well-being of humans. Anthropogenic pollution has been the focus of extensive research for some time and a variety of programs for the monitoring and assessment of environmental pollution have been developed. LÄS MER

  4. 3. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission

    Författare :Nancy P Nenonen; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norovirus; tracing; environment; foodborne; outbreak; waterborne; nosocomial; mussels; GI.1; oysters; GII.4; dust; surfaces; air; molecular epidemiology;

    Sammanfattning : Noroviruses (NoV), a major cause of acute gastroenteritis in hospital settings, also occur as sporadic infections or periodic non-seasonal community outbreaks. Human NoV replicates to high concentration in the intestinal tract, is readily transmitted by the faecal-oral route, hand-to-hand contact, contaminated food and water, and by aerosols. LÄS MER

  5. 4. Seawater pH as a Controlling Factor in Macroalgal Calcification and Photosynthesis

    Författare :Immaculate Sware Semesi; Mats Björk; Sven Beer; O. P. Rui Santos; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Calcareous macroalgae; CO2; mussels; pH; seagrasses; tropical lagoons; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Biological calcification and photosynthesis are important processes with a great influence on both structure and function of oceanic ecosystems. The pH of the seawater has a strong influence on both these processes and therefore the impacts of different pH levels on calcareous macroalgae were investigated in laboratory and field experiments at Chwaka and Fumba Bays in Zanzibar, Tanzania.

  7. 5. Climate change effects on marine species across trophic levels

    Författare :Nan Hu; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; trophic levels; predation; gastropods; mussels; ocean acidification; ocean warming; interactive effects; interaction types; meta-analysis;

    Sammanfattning : Climate change and anthropogenic activities are producing a range of new selection pressures, both abiotic and biotic, on marine organisms. While there are numerous studies that have investigated the response of individual marine organisms to climate change, few studies have focused on differences in organismal responses across trophic levels.
