  2. 2. Get a grip on chaos : Tailored measures for complex systems on surfaces

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sascha Firle; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; complex systems; chaos; predator prey; movement models; functional response; spatial heterogeneity; topological dynamics; braid template; homoclinic bifurcations; Kvantkemi; NATURAL SCIENCES Chemistry Theoretical chemistry Quantum chemistry; NATURVETENSKAP Kemi Teoretisk kemi Kvantkemi; Quantum Chemistry; kvantkemi;

    Abstract : Complex systems are ubiquitous in physics, biology and mathematics. This thesis is concerned with describing and understanding complex systems. Some new concepts about how large systems can be viewed in a lower dimensional framework are proposed. The systems presented are examples from ecology and chemistry. READ MORE

  3. 3. Effects of warming and nutrient enrichment on feeding behavior, population stability and persistence of consumers and their resources

    University dissertation from Umeå : Umeå University

    Author : Wojciech Uszko; Sebastian Diehl; Lennart Persson; David Vasseur; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; consumer-resource; Daphnia; functional response; nutrient enrichment; parameter estimation; persistence; plankton; predator-prey; stability; temperature; type II; type III; warming;

    Abstract : Consumer-resource interactions are the basic building blocks of every food web. In spite of being a central research theme of longstanding interest in ecology, the mechanisms governing the stability and persistence of consumer-resource interactions are still not entirely understood.

  4. 4. Predator effects on behaviour and life-history of prey

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Tomas Brodin; Frank Johansson; Bradley Anholt; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; activity; behaviour; behavioural syndromes; damselfly; development; growth; life-history; predator-prey interaction; predation risk; thinning; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Freshwater ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Limnisk ekologi;

    Abstract : In this thesis I investigate predator-induced effects on behavioural and life-history characteristics of prey. At any moment a given predator is capable of attacking a small number of prey. READ MORE

  5. 5. Antipredator defence in butterflies

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Martin Olofsson; Christer Wiklund; Graeme Ruxton; [2013]
    Keywords : 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
