• Breeding system, insect flower visitation, and floral traits of two alpine cerastium species in Norway 

      Totland, Ørjan; Schulte-Herbriiggen, Björn (Peer reviewed; Journal article, 1999)
      The pollination and reproductive ecology of Saxifraga stellaris was investigated in alpine southwest Norway. A breeding system analysis, with performance of controlled crosses, revealed that S. stellaris is self-compatible ...

      Nyléhn, Jorun; Totland, Ørjan (Peer reviewed; Journal article, 1999)
      The effects of temperature and "natural disturbance" on growth, seed production, and population density in the facultative hemiparasitic annual Euphrasia frigida (Scrophulariaceae) were examined in the middle alpine zone ...
    • Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields 

      Sawe, Thomas; Eldegard, Katrine; Totland, Ørjan; Macrice, Samora; Nielsen, Anders (Journal article; Peer reviewed, 2020)
      Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited ...
    • Experimental warming differentially affects vegetative and reproductive phenology of tundra plants 

      Collins, Courtney G.; Elmendorf, Sarah C.; Hollister, Robert D.; Henry, Greg H.

(Journal article; Peer reviewed, 2021)
      Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear ...
    • Forest fragmentation modifes the composition of bumblebee communities and modulates their trophic and competitive interactions for pollination 

      Gómez-Martínez, Carmelo; Aase, Anne Lene Thorsdatter Orvedal; Totland, Ørjan; Rodríguez-Pérez, Javier; Birkemoe, Tone; Sverdrup-Thygeson, Anne; Lázaro, Amparo (Journal article; Peer reviewed, 2020)
      Understanding the effects of landscape fragmentation on global bumblebee declines requires going beyond estimates of abundance and richness and evaluating changes in community composition and trophic and competitive ...
    • Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment 

      Arft, A. M.; Walker, M. D.; Gurevitch, J.; Alatalo, J. M.; Bret-Harte, M. S.; Dale, M.; Diemer, M.; Gugerli, F.; Henry, G. H. R.; Jones, M. H.; Hollister, R. D.; Jónsdóttir, I.

J.; Webber, P. J.; Welker, J. M.; Wookey, P. A. (Peer reviewed; Journal article, 1999)
      The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ...
    • Unfenced Borders Cause Differences in Vegetation and Fauna Between Protected and Unprotected Areas in a Tropical Savanna 

      Nyamukuru, Antonia; Grytnes, John-Arvid; Tabuti, John Robert Stephen; Totland, Ørjan (Peer reviewed; Journal article, 2019-09-04)
      Protected areas generally occur within a matrix of intensively human-modified landscapes. As a way to maintain the biodiversity in these areas, enclosure by fencing is often preferred. This strategy, however, is costly and ...
    • Willow canopies and plant community structure along an alpine environmental gradient 

      Totland, Ørjan; Grytnes, John-Arvid; Heegaard, Einar (Peer reviewed; Journal article, 2005)
      We examined the impact of Salix lapponum canopies on plantcommunity structure in five sites along a climatic gradient in aglacier foreland in alpine south Norway. Species richness is lowerinside canopies compared to outside ...
