    Birds show considerable variation in sperm morphology. Closely related species and subspecies can show diagnostic differences in sperm size. There is also variation in sperm size among males within a population, and recent ...
  • Edvardsen, Anette (Doctoral thesis / Doktoravhandling, 2010)
    This thesis addresses the spatial distribution and dynamics of vascular plant species in modern agricultural landscapes in SE Norway. This is done by analysing several data sets for species composition and environmental ...

    Studying herbal products derived from local and traditional knowledge and their value chains is one of the main challenges in ethnopharmacology. The majority of these products have a long history of use, but non-harmonized ...
  • Jacobsen, Rannveig Margrete; Birkemoe, Tone; Evju, Marianne; Skarpaas, Olav; Sverdrup-Thygeson, Anne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Old veteran trees function as biodiversity hotspots in both forests and open landscapes, and protecting such trees is an important measure to halt loss of biodiversity. Nevertheless, the number of veteran trees continues ...
  • Støstad, Hanna Nyborg; Rekdal, Silje Larsen; Kleven, Oddmund; Laskemoen, Terje; Marthinsen, Gunnhild; Johnsen, Arild; Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Sperm morphology is highly diversified among species and at higher taxonomic levels. In birds, there is also increasing evidence of geographical differentiation in sperm traits within species, especially in those with ...
  • Birkeland, Siri; Slotte, Tanja; Brysting, Anne Krag; Gustafsson, Lovisa; Hvidsten, Torgeir Rhoden; Brochmann, Christian; Nowak, Michael Dennis (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Little is known about the evolution of cold tolerance in polar plant species and how they differ from temperate relatives. To gain insight into their biology and the evolution of cold tolerance, we compared the molecular ...
  • Eller, Andrea R.; Canington, Stephanie L.; Saiyed, Sana T.; Austin, Rita M; Hofman, Courtney A.; Sholts, Sabrina B. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Objectives Natural history collections are often thought to represent environments in a pristine natural state—free from human intervention—the so-called “wild.” In this study, we aim to assess the level of human influence ...
  • Naas, Adam Eindride; Halvorsen, Rune; Horvath, Peter; Wollan, Anders Kvalvåg; Bratli, Harald; Brynildsrud, Katrine Marie; Finne, Eirik Aasmo; Keetz, Lasse Torben; Lieungh, Eva; Olson, Christine; Simensen, Trond; Skarpaas, Olav; Tandstad, Hilde; Torma, Michal; Værland, Espen Sommer; Bryn, Anders (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Questions: Field-based ecosystem mapping is prone to observer bias, typically resulting in a mismatch between maps made by different mappers, that is, inconsistency. Experimental studies testing the influence of site, ...
  • Lidgard, Scott; Di Martino, Emanuela; Zagorszek, Kamil; Liow, Lee Hsiang (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Examining the supposition that local-scale competition drives macroevolutionary patterns has become a familiar goal in fossil biodiversity studies. However, it is an elusive goal, hampered by inadequate confirmation of ...
  • Lifjeld, Jan Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
    Taxonomy is being increasingly informed by genomics. Traditionally, taxonomy has relied extensively on phenotypic traits for the identification and delimitation of species, though with a growing influence from molecular ...

    Natural selection in domestic dogs is of great interest in evolutionary biology since dogs have migrated to every inhabited continent of the world alongside humans, and adapted to diverse environments. Here, we explored ...
  • Speed, James David Mervyn; Chimal-Ballesteros, J. Adrian; Martin, Michael D.; Barrio, Isabel C.; Vuorinen, Katariina Elsa Maria; Soininen, Eeva M (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Poleward shifts in species distributions are expected and frequently observed with a warming climate. In Arctic ecosystems, the strong warming trends are associated with increasing greenness and shrubification. Vertebrate ...
