  1. 1. Saproxylic beetles in Populus tremula fauna depots - how do you construct the best depot?

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Simon Selberg; [2019]
    Nyckelord :aspen; populus; tremula; saproxylic; beetle; fauna; depot; species; richness; abundance; diversity; cwd; course; woody; debris; forest; asp; populus; tremula; vedlevande; skalbagge; fauna; depå; art; mångfald; diversitet; död; ved; cwd; skog;

    Sammanfattning : The biodiversity of saproxylic organisms and in the case of this study, saproxylic beetles, is dependent on the amount and quality of course woody debris (CWD) in the environment. Over the past decades the quantity of CWD in Swedish forests has increased, yet the quality has decreased, forests are managed and exploited, and old-growth forests are rarer. LÄS MER

    Sammanfattning : Chronic wasting disease (CWD) är en prionsjukdom som framförallt drabbar hjortdjur. Prionerär infektiösa protein som orsakar olika typer av transmissibla spongiforma encefalopatier. Andra prionsjukdomar är bovin spongiform encefalopati, Creutzfeldt-Jakobs sjukdom och scrapie.

  3. 3. An oasis without water : a hydro-social investigation into how agricultural water use and management influences water scarcity in the Ferghana Valley, Central Asia

    Master-uppsats, Lunds universitet/LUCSUS

    Författare :Oliver Watson; [2017]
    Nyckelord :water scarcity; Ferghana Valley; water user associations; remote sensing; mixed methods; sustainability science; Social Sciences;

    Sammanfattning : Water scarcity can have severe implications for society; endangering human health and food security whilst also exacerbating social conflict around the world. These issues are exemplified in the case of the Ferghana Valley in Central Asia, where much of the valley suffers from water scarcity and conflicts despite having adequate water sources. LÄS MER

  4. 4. Chronic wasting disease : en prionsjukdom

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Karin Klensmeden; [2017]
    Nyckelord :chronic wasting disease; CWD; prioner; hjortdjur; överföring;

    Sammanfattning : Chronic wasting disease (CWD) är en prionsjukdom hos som förekommer hos både vilda och hägnade hjortdjur. Sjukdomen har funnits i Nordamerika sedan 1960-talet, och upptäcktes för första gången i Europa år 2016 på en vildren i Norge. LÄS MER

  5. 5. Artificial gap creation and the saproxylic beetle community : the effect of substrate properties on abundance and species richness

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Nils Bodin; [2016]
    Nyckelord :boreal forest; nature conservation; saproxylic beetle; artificial gap creation; restoration measure; coarse woody debris;

    Sammanfattning : Coarse dead wood (CWD) and gaps are structures that have become sparse in Swedish forests as a result of forestry. This is believed to be one factor contributing to diminishing biodiversity. Because of political undertakings to preserve biodiversity, Swedish agencies and forestry companies now aim to restore these and other structures. LÄS MER
