Changing contributions of stochastic and deterministic processes in community assembly over a successional gradient
Måren, Inger Elisabeth; Kapfer, Jutta; Aarrestad, Per Arild; Grytnes, John-Arvid; Vandvik, Vigdis (Journal article; Peer reviewed, 2017)Successional dynamics in plant community assembly may result from both deterministic and stochastic ecological processes. The relative importance of different ecological processes is expected to vary over the successional ... -
Open-source data reveal how collections-based fungal diversity is sensitive to global change
Andrew, Carrie Joy; Büntgen, Ulf; Egli, Simon; Senn-Irlet, Beatrice; Grytnes, John-Arvid; Heilmann-Clausen, Jacob; Boddy, Lynne; Bässler, Claus; Gange, Alan C.; Heegaard, Einar; Høiland, Klaus; Kirk, Paul M.; Krisai-Greilhüber, Irmgard; Kuyper, Thomas W.; Kauserud, Håvard (Journal article; Peer reviewed, 2019)Premise of the Study Fungal diversity (richness) trends at large scales are in urgent need of investigation, especially through novel situations that combine long‐term observational with environmental and remotely sensed ... -
Red List updates and the robustness of sites selected for conservation of red-listed species
Gjerde, Ivar; Grytnes, John-Arvid; Heegaard, Einar; Sætersdal, Magne; Tingstad, Lise (Journal article; Peer reviewed, 2018)The long-term success of sites selected for species conservation depends on the persistence of target species. Red List species or threatened species lists are frequently defined as target species, but when Red Lists are ... -
Species trait selection along a prescribed fire chronosequence
Bargmann, Tessa; Heegaard, Einar; Hatteland, Bjørn Arild; Chipperfield, Joseph; Grytnes, John-Arvid (Journal article; Peer reviewed, 2016)1. Fire is a widespread management practice used in the maintenance of European heathland. Frequent prescribed burns in small patches have been shown to benefit carabid communities; however, how fire favours specific ... -
Species–area relationships in continuous vegetation: Evidence from Palaearctic grasslands
Dengler, Jürgen; Matthews, Thomas J.; Steinbauer, Manuel J.; Wolfrum, Sebastian; Boch, Steffen; Chiarucci, Alessandro; Conradi, Timo; Dembicz, Iwona; Marcenó, Corrado; García-Mijangos, Itziar; Nowak, Arkadiusz; Storch, David; Ulrich, Werner; Campos, Juan Antonio; Cancellieri, Laura; Carboni, Marta; Ciaschetti, Giampiero; De Frenne, Pieter; Doležal, Jiří; Dolnik, Christian; Essl, Franz; Fantinato, Edy; Filibeck, Goffredo; Grytnes, John-Arvid; Guarino, Riccardo; Güler, Behlül; Janišová, Monika; Klichowska, Ewelina; Kozub, Łukasz; Kuzemko, Anna; Manthey, Michael; Mimet, Anne; Naqinezhad, Alireza; Pedersen, Christian; Peet, Robert K.; Pellissier, Vincent; Pielech, Remigiusz; Potenza, Giovanna; Rosati, Leonardo; Terzi, Massimo; Valkó, Orsolya; Vynokurov, Denys; White, Hannah; Winkler, Manuela; Biurrun, Idoia (Journal article; Peer reviewed, 2019-09-19)Aim Species–area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes ... -
The influence of spatial scales on Red List composition: Forest species in Fennoscandia
Tingstad, Lise; Gjerde, Ivar; Dahlberg, Anders; Grytnes, John-Arvid (Journal article; Peer reviewed, 2017-08-08)National Red Lists are widely used prioritizing tools for nature conservation. However, status and trends of species vary with scale, and accounting for a larger spatial scale may provide complementary perspectives for ... -
The potential to use documentation in national Red Lists to characterize red-listed forest species in Fennoscandia and to guide conservation
Tingstad, Lise; Grytnes, John-Arvid; Felde, Vivian Astrup; Juslén, Aino; Hyvärinen, Esko; Dahlberg, Anders (Journal article; Peer reviewed, 2018-06-30)Loss of biodiversity is a pressing global issue, hence it is vital to facilitate informed and effective conservation. As conservation mainly operates at the level of habitats, aiming for species of conservation interest, ... -
Using Red List species in designating protection status to forest areas: a case study on the problem of spatio-temporal dynamics
Tingstad, Lise; Grytnes, John-Arvid; Sætersdal, Magne; Gjerde, Ivar (Peer reviewed; Journal article, 2020-08-12)Red-listed species are often used as target species in selection of sites for conservation. However, limitations to their use have been pointed out, and here we address the problem of expected high spatio-temporal dynamics ...
