  2. 1. Seasonal change in defensive coloration in a shieldbug

    Author : Aleksandra I. Johansen; Gabriella Gamberale-Stille; Birgitta S. Tullberg; Graeme Ruxton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Shield bug; colour change; protective coloration; cryptic; aposematic; behavioural change; etologi; Ethology;

    Abstract : Protective coloration such as aposematism and crypsis occurs in many insects but only a few species alter their defensive strategy during the same instar. We hypothesize the adult shield bug Graphosoma lineatum with an alternating black and non-melanised longitudinal striation exhibit such a change in defensive coloration. READ MORE

  4. 2. Phenotypic and social effects on behavioural trade-offs in Eurasian perch

    Author : Gustav Hellström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Trading between conflicting demands is a fundamental part in how animals interact with its environment and social surrounding. Knowledge of what factors that are affecting behavioural decisions is central in our understanding of animal adaptation and ecology. READ MORE

  5. 3. Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling

    Author : Caroline Schill; Therese Lindahl; Anne-Sophie Crépin; Johan Colding; Carl Folke; Juan Camilo Cárdenas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human behaviour; Common-pool resources; Ecological complexity; Collective action; Sustainable resource use; Regime shifts; Thresholds; Uncertainty; Communication; Knowledge-sharing; Economic experiments; Laboratory and field experiments; Agent-based modelling; Complex adaptive systems; Social-ecological systems; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. READ MORE

  6. 4. Polymer-Mediated Interactions and Phase Behaviour of Polymer-Particle Dispersions

    Author : Sara Haddadi; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulations; Experiments; Particles; Phase transition; Stability; capillary induced phase separation; Polymer solutions; phase diagram; surface effects; Bulk properties;

    Abstract : Interactions between colloidal particles can be modelled by particles grafted with polymers. In this work, structural and physical properties of colloids are investigated under variation of parameters such as pH, ionic strength, and temperature, where aggregation and cluster formation can be monitored in aqueous solution.

  7. 5. Making complex commons work : identifying critical social-ecological factors and mechanisms for sustainable ecosystem management

    Author : Caroline Schill; Therese Lindahl; Björn Vollan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agent-based modelling; Behavioural experiments; Collective action; Common-pool resources; Cooperation; Ecological complexity; Knowledge sharing; Regime shifts; Social-ecological systems; Sustainable management; Thresholds; Uncertainty; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Collective action holds the key to many sustainability challenges, from local to global scales. Whether it is to manage community-based fisheries or take action against climate change or biodiversity loss – the question on how to overcome the conflict between individual and collective interests (i.e. READ MORE
