  3. 3. Antipredator defence in butterflies

    Author : Martin Olofsson; Christer Wiklund; Graeme Ruxton; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Antipredator defence; Bird; Crypsis; Predator; Predator-prey interaction; Prey-attack behavior; Butterfly; Deimatic behavior; Eyespots; Startle display; zoologisk ekologi; Animal Ecology;

    Abstract : Predation exerts a potent selection mechanism and has resulted in a suite of antipredation adaptations encompassing morphological and behavioral traits in prey. In butterflies, several such traits appear to be directed towards birds which are considered as one of their major predators. READ MORE

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

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

    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

  5. 5. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces
