  2. 1. Microalgae : future bioresource of the sea?

    Author : Martin Olofsson; Catherine Legrand; Jukka Seppälä; Linnéuniversitetet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Impacts of multi-species deer communities on boreal forests across ecological and management scales

    Author : Sabine Pfeffer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : During the past decades, the population density and distribution of deer (Cervidae) has increased across Europe. Particularly in Sweden, this led to an increased cooccurrence of several deer species in landscapes highly dominated by humans. READ MORE

  5. 3. Food Web Ecology -- individual life-histories and ecological processes shape complex communities

    Author : Martin Hartvig; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; food web; community ecology; community assembly; size-structure; life-history omnivory; ontogeny; trophic interactions; trait based model; topology; emergent organisation; size-spectrum;

    Abstract : This thesis sets out a food web framework for size-structured populations. The framework enables an ecological approach to food web modelling as the individual life-history from birth, through maturation, and ultimately death is explicitly resolved with the use of bioenergetics based on individual body size.

  6. 4. Quantifying Risk in Epidemiological and Ecological Contexts

    Author : Stefan Sellman; Uno Wennergren; Bo Ebenman; Meggan Craft; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The rates of globalization and growth of the human population puts ever increasing pressure on the agricultural sector to intensify and grow more complex, and with this intensification comes an increased risk of outbreaks of infectious livestock diseases. At the same time, and for the same reasons, the detrimental effect that humans have on other species with which we share the environment has never been more apparent, as the current rates of species loss from ecological communities rival those of ancient mass extinction events.
