    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In recent years, carbon sequestration in European forests has decreased due to extensive droughts and bark beetle outbreaks brought on by climate change. The Eurasian spruce bark beetle (Ips typographus (L.)) is a natural disturbance agent in forests where Norway spruce (Picea abies (Karst)) is dominant. LÄS MER

  4. 3. Pulmonary tuberculosis and Pneumocystis jiroveci pneumonia in HIV-infected patients in Ethiopia

    Författare :Getachew Aderaye; Karolinska Institutet; Karolinska Institutet; []
