  1. 1. Genetic differences in Lobesia botrana populations : related to host plant or geographic origin?

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Sophia Döös; [2013]
    Nyckelord :Lobesia botrana; Grapevine moth; pest; vineyard; AFLP; SSR; population genetics; Daphne gnidium;

    Sammanfattning : For the past six decades the model of geographical isolation has been dominating but recently there has been a renewed interest in the possibility of sympatric speciation. Races of phytophagous insects specializing on different species of host plants have often been studied for the purpose of solving the question of sympatric speciation. LÄS MER

  3. 2. Does eutrophication cause directional genetic selection in three-spined stickleback (Gasterosteus aculeatus)? : A study of multiple Baltic Sea populations.

    Kandidat-uppsats, Institutionen för livsvetenskaper

    Författare :Malin Borg; [2011]
    Nyckelord :Gasterosteus aculeatus; Population genetics; Natural selection; Eutrophication; Baltic Sea; AFLP;

    Sammanfattning : Human-induced eutrophication is indirectly affecting aquatic organisms by altering their environment. This brings on altered selective pressures and could thereby cause changes in the genetic composition of exposed populations. LÄS MER

  5. 4. Population genetic structure and connectivity of the abundant sea urchin, Diadema setosum around Unguja island (Zanzibar).

    Kandidat-uppsats, Institutionen för livsvetenskaper

    Författare :Josefine Larsson; [2009]
    Nyckelord :Diadema setosum; population structure; Zanzibar; AFLP;

    Sammanfattning : The distribution and abundance of many coral reef organisms are affected by their predator’s distribution and abundance. Loss of predators may cause a shift in species compositions that will cascade down to other ecological processes on the reef. LÄS MER

  7. 5. Evolution toward pollution-resistant ecotypes of Baltic threespine stickleback, Gasterosteus aculeatus, suggested by AFLP markers

    Kandidat-uppsats, Institutionen för livsvetenskaper

    Författare :Ambjörn Johansson; [2008]
    Nyckelord :Microevolution; threespine stickleback; population genetics; genetic response; pollution;

    Sammanfattning : This study used amplified fragment length polymorphism (AFLP) to detect changes of genetic variation in threespine stickleback exposed to industrial pollution from pulp- and paper mills along the southern east coast of Sweden. A general loss of allelic diversity was associated with exposure (table 3, linear model, F1,4=7.2 [P=0. LÄS MER
