    Sperm morphological traits are highly variable among species and are commonly thought to evolve by post-copulatory sexual selection. However, little is known about the evolutionary dynamics of sperm morphology, and whether ...
  • Bonachela, Juan; Wortel, Meike Tessa; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The Red Queen Hypothesis proposes that perpetual co-evolution among organisms can result from purely biotic drivers. After more than four decades, there is no satisfactory understanding as to which mechanisms trigger Red ...
  • Supraha, Luka; Gerecht, Andrea Cornelia; Probert, Ian; Henderiks, Jorijntje (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    The steady increase in global ocean temperature will most likely lead to nutrient limitation in the photic zone. This will impact the physiology of marine algae, including the globally important calcifying coccolithophores. ...
  • Rindal, Valentina Lucia D'Adamo (Master thesis / Masteroppgave, 2016)
    Primates habitats are being increasingly fragmented by human activities worldwide. The behavioural flexibility exhibited by vervet monkeys (Chlorocebus pygerythrus) is assumed to be crucial in the species ability to persist ...
  • Nordbotten, Jan Martin; Levin, Simon A.; Szathmáry, Eörs; Stenseth, Nils Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    In this contribution, we develop a theoretical framework for linking microprocesses (i.e., population dynamics and evolution through natural selection) with macrophenomena (such as interconnectedness and modularity within ...
  • Barrett, James; Boessenkool, Sanne; Kneale, Catherine; O'Connell, Tamsin C; Star, Bastiaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The impacts of early ecological globalisation may have had profound economic and environmental consequences for human settlements and animal populations. Here, we review the extent of such historical impacts by investigating ...
  • Trosvik, Pål; Rueness, Eli Knispel; de Muinck, Eric; Moges, Amera; Mekonnen, Addisu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Human activities can cause habitat degradation that may alter the types and quality of available food resources and thus influence the microbiomes of wild animal populations. Furthermore, seasonal shifts in food availability ...
  • Spears, Bryan; Futter, Martyn N.; Jeppesen, Erik; Huser, Brian J; Ives, Stephen; Davidson, Thomas A; Adrian, Rita; Angeler, David G.; Burthe, Sarah J; Carvalho, Laurence; Daunt, Francis; Gsell, Alena S; Hessen, Dag Olav; Janssen, Annette B G; MacKay, Eleanor B; May, Linda; Moorhouse, Heather; Olsen, Saara; Søndergaard, Martin; Woods, Helen; Thackeray, Stephen J. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    There is a pressing need to apply stability and resilience theory to environmental management to restore degraded ecosystems effectively and to mitigate the effects of impending environmental change. Lakes represent excellent ...
  • Trosvik, Pål; de Muinck, Eric J (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Background Determining ecological roles of community members and the impact of specific taxa on overall biodiversity in the gastrointestinal (GI) microbiota is of fundamental importance. A step towards a ...
  • Solberg, Ingrid; Røstad, Anders; Kaartvedt, Stein (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We used moored upward-facing echosounders in combination with field campaigns to address the overwintering ecology of the clupeid sprat (Sprattus sprattus) throughout four separate winters in a Norwegian fjord. The stationary ...
  • Sperfeld, Erik; Nilssen, Jens Petter; Rinehart, Shelby Anne; Klaus, Schwenk; Hessen, Dag Olav (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract Inducible defenses against predators are widespread among plants and animals. For example, some Daphnia species form neckteeth against predatory larvae of the dipteran genus Chaoborus . Though thoroughly studied ...
  • Thoemmes, Megan S.; Stewart, Fiona A; Hernandez-Aguilar, Raquel Adriana; Bertone, Matthew A.; Baltzegar, David A.; Borski, Russell J.; Cohen, Naomi; Coyle, Kaitlin P.; Piel, Alexander K.; Dunn, Robert R. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The indoor environment created by the construction of homes and other buildings is often considered to be uniquely different from other environments. It is composed of organisms that are less diverse than those of the ...
  • Diaz Pauli, Beatriz; Edeline, Eric; Evangelista, Charlotte (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Intraspecific trait variation has large effects on the ecosystem and is greatly affected by human activities. To date, most studies focused on single-trait analyses, while considering multiple traits is expected to better ...
  • Mundra, Sunil; Halvorsen, Rune; Kauserud, Håvard; Bahram, Mohammad; Tedersoo, Leho; Elberling, Bo; Cooper, Elisabeth J.; Eidesen, Pernille Bronken (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Changing climate is expected to alter precipitation patterns in the Arctic, with consequences for subsurface temperature and moisture conditions, community structure, and nutrient mobilization through microbial belowground ...
