  1. 1. Investigation of the binding effect of fungal fiber (grown on apple pomace) in the formation of lyocell nonwoven textiles and their potential applications

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Xue Luo; [2021]
    Keywords : lyocell; nonwovens; binder; filamentous fungi; wet-laid; fungal microfibers; apple pomace; cellulose;

    Abstract : This project combines nonwoven technology, biological technology and food waste management and seeks for this feasibility to use fungal microfiber (FM) as a binder for lyocell pro-duction and the characterizations for possible applications. Rhizopus delemar was cultivated apple pomace in liquid-state fermentation to obtain mycelia biomass. READ MORE

  2. 2. Växt-växtbaserad kommunikation : hur sortblandningar påverkade tillväxten hos vårkorn

    University essay from SLU/Dept. of Ecology

    Author : Alexander Pettersson; [2021]
    Keywords : allelobios; allelopati; flyktiga organiska substanser; vårkorn;

    Abstract : Växter utgör grunden för många ekosystem och näringskedjor. Som platsbundna organismer behöver växter kunna anpassa sig efter de rådande förutsättningarna kring växtplatsen. Växter anpassar sig inte bara efter abiotiska faktorer, utan även stress från skadegörare och andra växter spelar en stor roll för en växtens överlevnad. READ MORE

  3. 3. 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

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

    University essay from SLU/Dept. Of Aquatic Resources

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

    Abstract : 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. READ MORE

  5. 5. Development of northern pike (Esox lucius) populations in the Baltic Sea, and potential effects of grey seal (Halichoerus grypus) predation

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Rebecka Svensson; [2021]
    Keywords : diet analysis; ; marine mammals; predator-prey; socio-economic; sport fishing; recreational fisheries;

    Abstract : Worldwide, marine mammal populations are increasing after considerable efforts to turn the downward trends caused by hunting, accidental mortality and pollution. The ecosystem effects from the increases of these top predators may be pronounced, but are in most cases poorly known. READ MORE
