  1. 1. Microalgae - future bioresource of the sea?

    Författare :Martin Olofsson; Catherine Legrand; Jukka Seppälä; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Sammanfattning : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. LÄS MER

  3. 2. Evaluating Swedish seaweeds for biorefinery

    Författare :Joakim Olsson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrothermal liquefaction; macroalgae; carbohydrates; proteins; chemical composition; Ulva spp.; ulvan; salinity; Seaweed; variation;

    Sammanfattning : A sustainable future demands a transition from oil to biomass to produce fuels, chemicals, commodities, and energy. However, to generate the predicted amount of bioenergy required by 2050, all the biomass harvested today should be utilized. One type of biomass that has received relatively little attention is seaweeds. LÄS MER

  4. 3. Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian Wetlands

    Detta är en avhandling från Nils Carlsson Värbyvägen 206, 230 40 Bara, Sweden

    Författare :Nils Carlsson; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gastropoda; invasive species; golden apple snail; herbivory; wetland functioning; biodiversity; sustainable control; indigenous predators; size-dependent competitive ability; akvatisk ekologi; limnologi; Marinbiologi; limnology; Hydrobiology; aquatic ecology; marine biology;

    Sammanfattning : The South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research has focused on effects of the snail in rice fields.

  5. 4. Disturbance Effects on Plant and Mycorrhizal Communities in Sandy Grasslands

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Tim Krone Schnoor; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Many ecosystems have historically been disturbed, either naturally or as part of a cultural management. Due to loss of species as a result of too little disturbance, disturbance must be considered as a potential tool for conservation and restoration in various ecosystems. In this thesis work, disturbance effects on a grassland system were studied. LÄS MER

  7. 5. Systems Modeling Approaches to Physical Resource Management An Industrial Ecology Perspective

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. LÄS MER
