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

    Författare :Martin Olofsson; Catherine Legrand; Jukka Seppälä; Linnéuniversitetet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

    Författare :Nils Carlsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 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.

  3. 3. Systems Modeling Approaches to Physical Resource Management : An Industrial Ecology Perspective

    Författare :Rajib Sinha; Björn Frostell; Maria Malmström; Miguel Brandao; Mujibur Rahman; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

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

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

  5. 5. Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

    Författare :Jagdeep Singh; Björn Frostell; Olga Kordas; Anju Singh; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industriell ekologi; Industrial Ecology;

    Sammanfattning : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. LÄS MER
