  1. 1. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Andreas Vernby; [2021]
    Keywords : Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

    Abstract : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. READ MORE

  3. 3. Swedish substrates suited for circular production of the edible gourmet mushroom maitake

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Anna Dahlin; [2021]
    Keywords : Grifola frondosa; maitake; mushroom production; spent mushroom substrate; circular production;

    Abstract : A selection of locally sourced substrates were evaluated for hyphal growth and fruiting body production of the edible gourmet mushroom maitake (Grifola frondosa). Hyphal growth was evaluated on a wide range of substrates (30) including different leaves, sawdust and waste from food production and the substrate that performed best was potato peelings, which showed development of a remarkably dense mycelium.
