  1. 1. Mellanskarven (Phalacrocorax carbo sinensis) i Krankesjön - Analys av långtidserier av skarvförekomster och fisksamhällets utveckling i kombination med bytesval

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Jonathan Loive; [2015]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : This study analyzed highly detailed long-term information about occurrence of cormorants (Phalacrocorax carbo sinensis) and the fish community composition in lake Krankesjön, southern Sweden. Moreover, cormorant predation with regards to species and size preference were estimated using data from recovered PIT (Passive Integrated Transponders) tags. LÄS MER

  3. 2. Storskarvens (Phalacrocorax carbo spp.) predation på Krankesjöns partiellt migrerande fiskpopulation

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Ville Ljungström Rautiainen; [2013]
    Nyckelord :Storskarv; Phalacrocorax carbo; partiell migration; fish; roach; rutilus rutilus; predation; Earth and Environmental Sciences;

    Sammanfattning : Partial migration, when only parts of a population migrate and others stay resident, is a common phenomenon in nature. The underlying explanation for the behavioural differences within a population remains a research question and several recent studies have highlighted the role of predation. LÄS MER

  4. 3. Storskarvens artpreferenser och påverkan på Krankesjöns fiskfauna - kan partiell migration för mörten minska risken att bli prederad?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Jonathan Loive; [2013]
    Nyckelord :Storskarv; Mört; Sarv; Partiell migration; Migrerande; Residenta; Krankesjön; Earth and Environmental Sciences;

    Sammanfattning : This study was conducted in two lakes, Krankesjön and Vombsjön, located in Lund, Sweden. We went out for four weeks during April in order to scan for PIT-tags eaten by cormorants (Phalacrocorax carbo). These PIT-tags have been implanted in more than 12000 fishes and 12 species during the period between 2003 and 2012. LÄS MER

  5. 4. Introduction of vegetation in large scale hydrodynamic models

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Goncalo Ferreira Cardoso; [2005]
    Nyckelord :Environmental technology; Väg- och vattenbyggnadsteknik; soil mechanics; vegetation modelling; vegetation modeling; lake hydrodynamics; shallow lakes; hydrodynamic models; hydraulics; Technological sciences; Teknik; Civil engineering; offshore technology; hydraulic engineering; pollution control; Miljöteknik; kontroll av utsläpp; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : Vegetation is known to have different effects in shallow water environments, including changes in hydrodynamics. This often creates the need to include vegetation in large scale hydrodynamic models, which nowadays can already be achieved using some software packages available in the market. LÄS MER
