    • DNA barcoding a taxonomically complex hemiparasitic genus reveals deep divergence between ploidy levels but lack of species-level resolution 

      Wang, Xumei; Gusarova, Galina; Ruhsam, Markus; de Vere, Natasha; Metherell, Chris; Hollingsworth, Peter M.; Twyford, Alex D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-24)
      DNA barcoding is emerging as a useful tool not only for species identification but also for studying evolutionary and ecological processes. Although plant DNA barcodes do not always provide species-level resolution, the generation of large DNA barcode data sets can provide insights into the mechanisms underlying the generation of species diversity. Here, we study evolutionary processes in taxonomically ...

    • Late Quaternary dynamics of Arctic biota from ancient environmental genomics 

      Wang, Yucheng; Pedersen, Mikkel W.; Alsos, Inger Greve; De Sanctis, Bianca; Racimo, Fernando; Prohaska, Ana; Coissac, Eric; Owens, Hannah L.; Merkel, Marie Føreid; Fernandez-Guerra, Antonio; Rouillard, Alexandra; Lammers, Youri; Alberti, Adriana; Denoeud, France; Money, Daniel; Ruter, Anthony H.; McColl, Hugh; Larsen, Nicolaj K.; Cherezova, Anna A.; Edwards, Mary E.; Fedorov, Grigory B.; Haile, James; Orlando, Ludovic; Vinner, Lasse; Korneliussen, Thorfinn S.; Beilman, David W.; Bjørk, Anders A.; Cao, Jialu; Dockter, Christoph; Esdale, Julie; Gusarova, Galina; Kjeldsen, Kristian K.; Mangerud, Jan; Rasic, Jeffrey T.; Skadhauge, Birgitte; Svendsen, John Inge; Tikhonov, Alexei N.; Wincker, Patrick; Xing, Yingchun; Zhang, Yubin; Froese, Duane G.; Rahbek, Carsten; Nogues, David B; Holden, Philip B.; Edwards, Neil R.; Durbin, Richard; Meltzer, David J.; Kjær, Kurt H.; Moller, Per; Willerslev, Eske (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-20)
      During the last glacial–interglacial cycle, Arctic biotas experienced substantial climatic changes, yet the nature, extent and rate of their responses are not fully understood1,2,3,4,5,6,7,8. Here we report a large-scale environmental DNA metagenomic study of ancient plant and mammal communities, analysing 535 permafrost and lake sediment samples from across the Arctic spanning the past 50,000 years. ...

    • Shedding new light on the diet of Norwegian lemmings: DNA metabarcoding of stomach content 

      Soininen, Eeva Marjatta; Zinger, Lucie; Gielly, Ludovic; Bellemain, Eva; Bråthen, Kari Anne; Brochmann, Christian; Epp, Laura; Gusarova, Galina; Hassel, Kristian; Henden, John-André; Killengreen, Siw Turid; Rämä, Teppo; Stenøien, Hans; Yoccoz, Nigel; Ims, Rolf Anker (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Lemmings are key herbivores in many arctic food webs, and their population dynamics have major impacts on the functioning of tundra systems. However, current knowledge of lemming diet is limited, hampering evaluation of lemming–vegetation interactions. This lack of knowledge is mainly due to methodological challenges, as previously used microhistological methods result in large proportions of poorly ...

    • Systematics and distribution of spruce species in the North-West of Russia 

      Orlova, Larisa; Gusarova, Galina; Glazkova, Elena; Egorov, Alexander; Potokin, Alexander; Ivanov, Sergey (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      Norway spruce (Picea abies) and Siberian spruce (P. obovata) are among the most important forest-forming coniferous species in the boreal part of Eurasia. Despite numerous publications on the taxonomy of Norway spruce and closely related taxa (P. obovata Ledeb. and P. fennica (Regel) Kom.), the problem of their identification, as well as clarification of their taxonomic status, has not been solved ...
