  1. 11. Efficiency of diatom and flagellate-based marine food webs.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Yasmina Hamladji; [2021]
    Keywords : phytoplankton; flagellate; diatoms; ciliates food web efficiency; fungi;

    Abstract : Aquatic microbial food webs are in general size structured. Phytoplankton, which constitute the base of the food web, are grazed by protozoa and mesozooplankton, which in turn are consumed by planktivorous fish. Food web efficiency (FWE) is a measure of how efficiently energy is transported up the food web. READ MORE

  5. 14. Nitrogen runoff, constructed wetlands and the effect on catch of fish in the Öresund strait

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Saga Hedstigen Sundblad; [2020]
    Keywords : seafloor oxygen demand; fish catch; constructed wetland; Earth and Environmental Sciences;

    Abstract : Eutrophication and low dissolved oxygen levels are spreading all over the world, causing changes in fish distribution and decline in fish abundance and catch of fish. This study assesses the current nitrogen (N) surface runoff to the Öresund strait, the seafloor oxygen demand it cause, the subsequent effect on fish catch, and the constructed wetland area needed to retain current N loads.
