  2. 1. Spring Phenology of Butterflies : The role of seasonal variation in life-cycle regulation

    Author : Sandra Stålhandske; Olof Leimar; Karl Gotthard; Wolf Blanckenhorn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phenology; Life cycle regulation; Phenotypic plasticity; Local adaptation; Butterflies; Diapause; Pupal development; Anthocharis cardamines; Herbivore – host plant interaction; etologi; Ethology;

    Abstract : Animals and plants in temperate regions must adapt their life cycle to pronounced seasonal variation. The research effort that has gone into studying these cyclical life history events, or phenological traits, has increased greatly in recent decades. READ MORE

  4. 2. Birds and butterflies at the forest-farmland interface

    Author : Dafne Ram; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation; Monitoring; Forestry; Grassland butterflies; Farmland birds;

    Abstract : Land-use change is one of the greatest threats to biodiversity. Through intensification of land-use, the agricultural landscape has become more homogenous and a result, many species associated with traditional farmland or other semi-natural open habitats have declined. READ MORE

  5. 3. Effects of climate on phenological synchrony between butterflies and their host plants

    Author : Diana Posledovich; Karl Gotthard; Christer Wiklund; Johan Ehrlén; Boggs Carol; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phenology; phenological synchrony; Anthocharis cardamines; Pieris napi; latitudinal variation; zoologisk ekologi; Animal Ecology;

    Abstract : Shifts in species’ phenologies and phenological asynchronies between the interacting organisms have received a lot of attention in the context of climate change. Changes in temporal overlap between species, caused by phenological asynchrony, make species depending on one another become so separated in time that they can no longer interact. READ MORE

  6. 4. Effect of climate and land use on niche utilization and distribution of nettle-feeding  butterflies

    Author : Hélène Audusseau; Niklas Janz; Sören Nylin; Matthew Forister; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Abstract : Anthropogenic changes in climate and land use are causing a dramatic erosion of biodiversity. To understand this erosion, and predict future transformations of biodiversity, we need to understand better species’ response to these changes at different spatial and temporal scales. READ MORE

  7. 5. Temperature and the synchrony of plant-insect interactions

    Author : Tenna Toftegaard; Johan Ehrlén; Karl Gotthard; Christer Wiklund; Annette Menzel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brassicaceae; Anthocharis cardamines; climate change; development; oviposition; phenology; species interactions; herbivory; synchrony; timing; phenotypic plasticity; local adaptation; Plant Ecology; växtekologi;

    Abstract : Increasing temperatures resulting from climate change have within recent years been shown to advance phenological events in a large number of species worldwide. Species can differ in their response to increasing temperatures, and understanding the mechanisms that determine the response is therefore of great importance in order to understand and predict how a warming climate can influence both individual species, but also their interactions with each other and the environment.
