  2. 11. Cellular mechanisms of plant regeneration

    Author : Theodore Serivichyaswat; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plants are remarkable at healing. Humankind has long known about this and has exploited it by grafting different plants together for crop propagation and crop improvement. During graft formation, the surfaces of the cut tissues attach, the cells proliferate, and the vasculatures reconnect to form a chimeric plant. READ MORE

  4. 12. Egg carrying in the golden egg bug

    Author : Minna Miettinen; Ingrid Ahnesjö; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hemiptera; Halvvingar; zoologi; Zoology;

    Abstract : Females of the golden egg bug, Phyllomorpha laciniata Vill (Heteroptera, Coreidae), lay their eggs on the backs of male and female conspecifics. Eggs survive poorly in nature unless being carried by living conspecifics. The most likely evolutionary explanation to egg carrying is that individuals carry their own eggs. READ MORE

  5. 13. Exploration of microbial diversity and evolution through cultivation independent phylogenomics

    Author : Joran Martijn; Thijs J.G. Ettema; Andrew Roger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cultivation independent genomics; metagenomics; single-cell genomics; metagenomic binning; phylogenetics; phylogenomics; phylogenetic artefacts; comparative genomics; gene tree-species tree reconciliation; rRNA amplicon sequencing; Tara Oceans; origin of mitochondria; Alphaproteobacteria; Rickettsiales; Haloarchaea; endosymbiosis; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Our understanding of microbial evolution is largely dependent on available genomic data of diverse organisms. Yet, genome-sequencing efforts have mostly ignored the diverse uncultivable majority in favor of cultivable and sociologically relevant organisms. READ MORE

  6. 14. Who ate whom? Paleoecology revealed through synchrotron microtomography of coprolites (fossil feces)

    Author : Martin Qvarnström; Živilė Žigaitė; Grzegorz Niedźwiedzki; Per Ahlberg; Karen Chin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coprolites; paleoecology; synchrotron microtomography; taphonomy; Triassic; Biologi; Biology;

    Abstract : Fossil droppings, known as coprolites, are being increasingly recognized as a valuable source of paleoecological information with special regard to diets, parasitism, and physiology of extinct taxa. Here, it is suggested that the excellent preservation and amount of inclusions in the coprolites (e.g. READ MORE

  7. 15. Biological control strategies against the cabbage root fly Delia radicum : effect of predators, parasitoids and pathogens

    Author : Linda-Marie Rännbäck; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Contemporary intensified agroecosystems are contributing to a reduction in natural enemy (NE) populations. In conservation biological control (CBC), NEs are favoured by providing supporting resources. CBC could be complemented with inoculation biological control (IBC) to enhance the effect of NEs.
