  • Competition and interdependence define interactions of Nostoc sp. and Agrobacterium sp. under inorganic carbon limitation 

    Teikari, Jonna E.; Russo, David A.; Heuser, Markus; Baumann, Otto; Zedler, Julie A. Z.; Liaimer, Anton; Dittmann, Elke (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-03-08)
    Cyanobacteria of the Nostoc genus are capable of forming symbiotic relationships with plants but also serve as a hub for heterotrophic bacteria. By comparing the axenic strain Nostoc punctiforme PCC 73102 and the xenic strains Nostoc sp. KVJ2 and KVJ3, we were able to demonstrate an almost obligate dependence of the cyanobacteria on the heterotrophic partners under carbon-limiting conditions. A ...

  • Trail cameras can greatly inflate nestpredation rates 

    Henden, John Andre; Ims, Rolf Anker; Strømeng, Marita Anti (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-27)
    Photographic monitoring currently provides the most accurate means for identifying nest predators and eventually their role in bird population declines worldwide. However, previous studies have found that commercially available trail cameras represent an artificial structure that tend to negatively bias predation rates, likely through predator neophobia. Based on an experiment in Arctic tundra, ...
