  1. 1. En jämförande studie av vattenfiltreringsegenskaper mellan musslor inom olika habitat

    Kandidat-uppsats, Karlstads universitet

    Författare :Jesper Rickard; [2023]
    Nyckelord :Unio Tumidus; Freshwater mussels; Water filtration; Aquatic ecology; Acclimatization time; Biology; Unio Tumidus; sötvattenmusslor; Vattenfiltrering; Akvatisk ekologi; Aklimationstid; Biologi;

    Sammanfattning : Denna studie handlar om den vanliga sötvattensmusselarten Unio tumidus (U. tumidus), som har en viktig roll i vattenrening genom att filtrera organiskt material. LÄS MER

  3. 2. Declining abundance and shifting distribution for Antarctic krill, Euphausia superba, in the western Antarctic Peninsula

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Kerstin Holmström; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Antarctic krill, Euphausia superba, a polar ocean specialist, thrives in the Antarctic severe physical conditions. The krill life cycle consists of strategies that have enabled and supported the species’ dominance of the Antarctic Ocean. Sea Ice extent and duration creates condition that are crucial for survival of the Furcilia larvae. LÄS MER

  4. 3. Can body size parameters be used to distinguish the Kattegat cod (Gadus morhua) stock from the North Sea cod stock?

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Viktor Hedlund; [2017]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Atlantic cod is one of the world´s most important commercial fish stocks and is dependent on fishing regulations for its wellbeing and survival. An important part in fisheries management is information of the stock distribution. This is needed to not cause overestimations that results in heavy overfishing. LÄS MER

  5. 4. Investigating epifauna community assembly in shallow bays using traits

    Master-uppsats, Stockholms universitet/Institutionen för ekologi, miljö och botanik

    Författare :Ola Pettersson; [2016]
    Nyckelord :Ecology; Traits; Baltic Sea; Aquatic ecology; Shallow bays; Ekologi; Akvatisk ekologi; Östersjön; Egenskaper; Grunda vikar;

    Sammanfattning : Ecological studies are often performed to investigate ecosystems from a taxonomic point of view (e.g. species richness or species composition). However, investigating variations in organism traits, rather than variations based on taxonomy, can yield higher mechaninistic understanding of the ecosystem. LÄS MER

  7. 5. 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
