  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. Geographic variation in life cycles : Local adaptation and ecological genetics in a temperate butterfly

    Author : Olle Lindestad; Karl Gotthard; Sören Nylin; Christopher W Wheat; Greg Ragland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; voltinism; local adaptation; insect; life cycle; seasonality; genomics; life history; zoologisk ekologi; Animal Ecology;

    Abstract : Conditions in nature change with the seasons, necessitating seasonal adaptations that synchronize the life cycles of organisms with their surroundings. Such regulatory adaptations must vary between populations to track local variation in climate and seasonality; this local adaptation is facilitated by locally specific seasonal cues, but may be hampered by gene flow and genetic history.

  5. 3. How precise is cyclic life? : Insights during a single molecule revolution of the bacterial cell cycle

    Author : Mats Walldén; Johan Elf; Peter Graumann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; E.coli; cell cycle; replication initiation; transcription factor; gene-regulation; single molecule microscopy; microfluidics; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Abstract : Bacterial cells reproduce by doubling in size and dividing. The molecular control systems which regulate the cell cycle must do so in a manner which maintains a similar cell size over many generations. A cell can under conditions of fast growth conclude cell cycles in shorter time than the time required to replicate its chromosome. READ MORE

  6. 4. An Emerging Product Approach in Environmental Law: Incorporating the life cycle perspective

    Author : Carl Dalhammar; Internationella miljöinstitutet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Trade and environment; Product regulation; IPP; Integrated product policy; Life cycle thinking; Environmental product policy; Environmental law; Miljörätt;

    Abstract : One of the noticeable trends in recent years is that products have received increasing attention in environmental policy. The focus on products and their life cycle impacts is often referred to as ?life cycle thinking?. READ MORE

  7. 5. Regulation of differentiation during the Giardia life cycle : An insight into the molecular control

    Author : Laura Rojas-López; Staffan Svärd; Marco Lalle; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; cell differentiation; encystation; histone post-translational modifications; host-parasite interaction;

    Abstract : Giardia intestinalis (syn. G. lamblia, G. duodenalis) is an intestinal protozoan parasite that causes diarrheal infections worldwide. READ MORE
