Assessing Norwegian pollination deficits. Capacity building towards IPBES - implementation and methodological evaluation of the “Protocol to Detect and Assess Pollination Deficits in crops.
Åström, Jens; Dramstad, Wenche; Debella-Gilo, Misganu; Hovstad, Knut Anders; Åström, Sandra Charlotte Helene; Rusch, Graciela (Research report, 2014)In 2012, the Norwegian Environmental Agency funded an extension to the Global Pollination Project, coordinated by the FAO (Food and Agriculture Organization of the United Nations) to expand the number of connected countries ... -
At which spatial and temporal scales can fungi indicate habitat connectivity?
Nordén, Jenni; Åström, Jens; Josefsson, Torbjörn; Blumentrath, Stefan; Ovaskainen, Otso; Sverdrup-Thygeson, Anne; Nordén, Björn (Journal article; Peer reviewed, 2018)Isolation of habitats in space and time affects species globally and in a multitude of ecosystems. It is however often difficult to assess the level of isolation from the point of view of the focal species. Indicator species ... -
Climate influence on plant–pollinator interactions in the keystone species Vaccinium myrtillus
Olsen, Siri Lie; Evju, Marianne; Åström, Jens; Løkken, Jørn Olav; Dahle, Sondre; Andresen, Jonas; Eide, Nina Elisabeth (Journal article; Peer reviewed, 2022)Climate change is altering the world's ecosystems through direct effects of climate warming and precipitation changes but also indirectly through changes in biotic interactions. For instance, climate-driven changes in plant ... -
Designing a surveillance program for early detection of alien plants and insects in Norway
Sandercock, Brett; Davey, Marie Louise; Endrestøl, Anders; Blaalid, Rakel; Fossøy, Frode; Hegre, Hanne; Majaneva, Markus; Often, Anders; Åström, Jens; Jacobsen, Rannveig Margrete (Journal article; Peer reviewed, 2022)Naturalized species of alien plants and animals comprise < 3% of biodiversity recorded in Norway but have had major impacts on natural ecosystems through displacement of native species. Encroachment of alien species has ... -
Interaction between Bombus terrestris and honeybees in red clover fields reduces abundance of other bumblebees and red clover yield
Müller, Helene Totland (Master thesis, 2016-11-17)Pollinator dependent crops have increased by 300% the last 50 years. At the same time many pollinator species are declining, including honeybees and bumblebees. Red clover is one of the crops dependent on bees for seed ... -
Priority maps for pollinator habitat enhancement schemes in semi-natural grasslands
Sydenham, Markus A. K.; Eldegard, Katrine; Venter, Zander; Evju, Marianne; Åström, Jens; Rusch, Graciela (Journal article; Peer reviewed, 2022)Conserving semi-natural grasslands, a threatened habitat type in European landscapes, is increasingly recognized as a measure to conserve pollinators. Our aim was to test if (a) prediction maps of solitary bee species ...
