A standard protocol for describing the evaluation of ecological models
Planque, Benjamin; Aarflot, Johanna Myrseth; Buttay, Lucie; Carroll, JoLynn; Fransner, Sara Filippa Krusmynta; Hansen, Cecilie; Husson, Berengere; Langangen, Øystein Ole Gahr; Lindstrøm, Ulf Ove; Pedersen, Torstein; Primicerio, Raul; Sivel, Elliot Manuarii; Skogen, Morten D.; Strombom, Evelyn; Stige, Leif Christian; Varpe, Øystein; Yoccoz, Nigel (Peer reviewed; Journal article, 2022)Numerical models o ecological systems are increasingly used to address complex environmental and resource management questions. One challenge or scientists, managers, and stakeholders is to appraise how well suited these ... -
Combined effects of temperature and fishing mortality on the Barents Sea ecosystem stability
Sivel, Elliot Manuarii; Planque, Benjamin; Lindstrøm, Ulf Ove; Yoccoz, Nigel (Peer reviewed; Journal article, 2022)Temporal variability in abundance and composition of species in marine ecosystems results from a combination of internal processes, external drivers, and stochasticity. One way to explore the temporal variability in an ... -
A Dynamic Occupancy Model for Interacting Species with Two Spatial Scales
Kleiven, Eivind Flittie; Barraquand, Frédéric; Gimenez, Olivier; Henden, John-André; Ims, Rolf Anker; Soininen, Eeva M; Yoccoz, Nigel (Peer reviewed; Journal article, 2023)Occupancy models have been extended to account for either multiple spatial scales or species interactions in a dynamic setting. However, as interacting species (e.g., predators and prey) often operate at different spatial ... -
Maximizing sampling efficiency to detect differences in fish community composition using environmental DNA metabarcoding in subarctic fjords
Guri, Gledis; Westgaard, Jon-Ivar; Yoccoz, Nigel; Wangensteen, Owen S.; Præbel, Kim; Ray, Jessica Louise; Kelly, Ryan P.; Shelton, Andrew Olaf; Hanebrekke, Tanja Lexau; Johansen, Torild (Peer reviewed; Journal article, 2023)Environmental DNA (eDNA) has gained popularity as a tool for ecosystem biomonitoring and biodiversity assessment. Although much progress has been made regarding laboratory and fieldwork protocols, the issue of sampling ... -
Postglacial species arrival and diversity buildup of northern ecosystems took millennia
Alsos, Inger Greve; Rijal, Dilli Prasad; Ehrich, Dorothee; Karger, Dirk Nikolaus; Yoccoz, Nigel; Heintzman, Peter D.; Brown, Antony; Lammers, Youri; Pellissier, Loïc; Alm, Torbjørn; Bråthen, Kari Anne; Coissac, Eric; Merkel, Marie Føreid; Alberti, Adriana; Denoeud, France; Bakke, Jostein (Peer reviewed; Journal article, 2022)What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete ... -
Resource‐driven colonization by cod in a high Arctic food web
Johannesen, Edda; Yoccoz, Nigel; Tveraa, Torkild; Schackell, Nancy L.; Ellingsen, Kari; Dolgov, Andrey V.; Frank, Kenneth T. (Peer reviewed; Journal article, 2020)1. Climate change is commonly associated with many species redistributions and the influence of other factors may be marginalized, especially in the rapidly warming Arctic. 2. The Barents Sea, a high latitude large marine ... -
The rise of a marine generalist predator and the fall of beta diversity
Ellingsen, Kari; Yoccoz, Nigel; Tveraa, Torkild; Frank, Kenneth T.; Johannesen, Edda; Anderson, Marti J.; Dolgov, Andrey V.; Shackell, Nancy L. (Peer reviewed; Journal article, 2020)Determining the importance of physical and biological drivers in shaping biodiversity in diverse ecosystems remains a global challenge. Advancements have been made towards this end in large marine ecosystems with several ... -
