  1. 1. Bio-optics, satellite remote sensing and Baltic Sea ecosystems : Applications for monitoring and management

    Author : Therese Harvey; Susanne Kratzer; Jakob Walve; Petra Philipson; Stiig Markager; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bio-optics; Remote sensing; MERIS; Eutrophication; Baltic Sea; Monitoring; Management; WFD; MSFD; HELCOM; Chlorophyll-a; Secchi depth; Coloured Dissolved Organic Matter; Suspended Particulate Matter; marin ekologi; Marine Ecology;

    Abstract : Earth observation satellites cover large areas with frequent temporal repetition and provide us with new insight into ocean and coastal processes. Ocean colour measurements from satellite remote sensing are linked to the bio-optics, which refers to the light interactions with living organisms and dissolved and suspended constituents in the aquatic environment.

  2. 2. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae

    Author : Anneleen Kool; Mats Thulin; Gudrun Kadereit; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; BEAST; Corrigiola; DNA barcoding; Morocco; Pollichia; Polycarpon; Polycarpaea; RAxML; Sanctambrosia; Spergula; Spergularia; Sphaerocoma;

    Abstract : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. READ MORE

  3. 3. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)

    Author : Martin Reutgard; Magnus Breitholtz; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Environmental health assessment; environmental monitoring; chemical pollution; hypoxia; bioindicators; biomarkers; teratogenicity; embryo toxicity; oxidative stress; acetylcholine esterase. Monoporeia affinis; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.

  4. 4. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia

    Author : Anna Palmé; Nils Ryman; Linda Laikre; Kerry Naish; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; biological diversity; conservation genetics; management unit; spatial genetic structure; sympatric populations; genetic monitoring; release of alien populations; northern pike; brown trout; harbour porpoise; Biology; Biologi; populationsgenetik; Population Genetics;

    Abstract : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. READ MORE

  5. 5. Predator responses to non-stationary rodent cycles

    Author : Peter Hellström; Anders Angerbjörn; Xavier Lambin; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Buteo lagopus; Vulpes lagopus; Lemmus; Myodes; population cycles; predation; numerical response; functional response; arctic; lemmings; voles; fox; monitoring; raptors; zoologisk ekologi; Animal Ecology;

    Abstract : Regular fluctuations in population size, cycles, are common in small mammals and have important effects on predator populations and life histories. In this thesis, I identify long-term patterns and processes in two specialist predators, the arctic fox Vulpes lagopus and the rough-legged buzzard Buteo lagopus, in relation to their prey (lemmings and voles) and in the case of the arctic fox also to a dominant competitor, the red fox Vulpes vulpes.
