  2. 16. Heuristic optimization of the p-median problem and population re-distribution

    Author : Mengjie Han; Kenneth Carling; Johan Håkansson; Pascal Rebreyend; David Philip McArthur; Högskolan Dalarna; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : This thesis contributes to the heuristic optimization of the p-median problem and Swedish population redistribution.  The p-median model is the most representative model in the location analysis. READ MORE

  4. 17. Ontogenetic scaling and the development of within-cohort size structure

    Author : Magnus Huss; Lennart Persson; Pär Byström; David Post; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cannibalism; competition; density-dependence; resource feedbacks; hatching; growth; ontogenetic niche shifts; Perca fluviatilis; size variation; larval fish; Freshwater ecology; Limnisk ekologi; zooekologi; Animal Ecology;

    Abstract : It is increasingly recognized that individuals of the same species differ from each other and influence and respond to their environment in unique ways. This thesis deals with size variation among individuals that not only are of the same species but also of similar age. READ MORE

  5. 18. The role of herbivores in mediating responses of tundra ecosystems to climate change

    Author : Elina Kaarlejärvi; Johan Olofsson; Anu Eskelinen; Jon Moen; Eric Post; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; grazer; Rangifer; Lemmus lemmus; species distribution; biotic interactions; altitude; Environmental Science; miljövetenskap;

    Abstract : The Arctic areas are warming more rapidly than other parts of the world. Increasing temperatures are predicted to result in shrubification, higher productivity, declining species diversity and new species invasions to the tundra. READ MORE

  6. 19. The impact of cormorant nesting colonies on plants and arthropods

    Author : Gundula S. Kolb; Peter Hambäck; Lenn Jerling; Post David; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; seabirds; cormorants; islands; nitrogen; phosphorus; plants; arthropods; δ15N; Baltic Sea; ecological stoichiometry; species richness; species composition; numeric response; Biology; Biologi; Plant Ecology; växtekologi;

    Abstract : Seabirds concentrate large amounts of marine nutrients on their nesting islands. This nutrient input can have large consequences for island food webs and community structure. The high nutrient load may also cause runoff into surrounding waters and affect marine communities. READ MORE

  7. 20. Immune cell infiltration and prognosis in colorectal cancer

    Author : Agnes Ling; Richard Palmqvist; Sofia Edin; Xingru Li; Ola Winqvist; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Colorectal cancer; molecular subgroups; immune cell infiltration; immune escape; prognosis;

    Abstract : Background: Colorectal cancer (CRC) is globally the second most common form of cancer among women, and third in men. It is also one of the most common causes of cancer-related death in high-income countries. Surgical resection is the basis for curative therapy but still almost half of the patients die from metastatic disease. READ MORE
