  1. 6. Effekten av kantzoners bredd på terrestra evertebraters nedfall till skogliga vattendrag

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jeanette Karlsson; [2021]
    Nyckelord :Buffert zones; invertebrates; Kantzoner; evertebrater;

    Sammanfattning : Kantzoner längst vattendrag i skogen är en komplex och artrik miljö som är av stor vikt för flertalet arter. Ett stort hot mot kantzoner är skogsindustrin och främst kalavverkning som kan ha en negativ effekt på hela ekosystem. Det finns idag ingen lag som kräver att kantzoner längst vattendrag bevaras med det rekommenderas. LÄS MER

  3. 7. Oolites from the Arabian platform: Archives for the aftermath of the end-Triassic mass extinction

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Johannes Greiff; [2021]
    Nyckelord :sedimentology; carbonates; geochemistry; oolites; ooids; thrombolites; microbialites; Triassic; Jurassic; Hettangian; extinction; United Arab Emirates; Wadi Ghalilah; Wadi Milaha; Earth and Environmental Sciences;

    Sammanfattning : The end-Triassic mass extinction (ETME) which occurred around 201 Ma is known as one of “the big five” mass extinction events of the Phanerozoic eon. Its effects were most severe on marine ecosystems, resulting in a global decline of invertebrate taxa and the complete extinction of the conodonts. LÄS MER

  4. 8. Tawny owl ( Strix aluco ) and its variation in diet between years

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Casper Ekberg; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The tawny owl resides in temperate forests in Europe and mainly hunts rodents but can also hunt other animals like birds,invertebrates and bats. In this study I examined how the diet of tawny owls varies during the span of 2018-2020, I also compared the diet found from nest boxes with footage obtained from cameras inside the nestboxes.

  5. 9. The effects of eutrophication and browning on prey availability and performance of the three-spined stickleback (Gasterosteus aculeatus)

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Olivia Bell; [2021]
    Nyckelord :Baltic Sea; benthic habitats; body growth; climate change; coastal areas; diet; fish; stickleback; zooplankton;

    Sammanfattning : Shallow coastal areas often have high productivity and diversity, in part due to the high availability of light and nutrients. At the same time, they are exposed to multiple environmental pressures, such as browning and eutrophication. LÄS MER

  7. 10. Quantifying panarchy of lake systems: implication for resilience and management (Case study)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ran Hur; [2021]
    Nyckelord :Sustainable Development; Liming; Panarchy; Resilience; Lake ecosystem; Natural resource management;

    Sammanfattning : Liming has been used extensively in Sweden, but the management success has been only partial, mostly mitigating the impact of acidification rather than restoring the ecological communities to a self-maintaining pre-acidified state. Rather than a sound restoration tool, liming is a form of command-and-control management that comprises a significant disturbance in the system, which manifests in the form of profound alterations of biophysical settings of lakes.
