At which spatial and temporal scales can fungi indicate habitat connectivity?
Nordén, Jenni; Åström, Jens; Josefsson, Torbjörn; Blumentrath, Stefan; Ovaskainen, Otso; Sverdrup-Thygeson, Anne; Nordén, Björn (Journal article; Peer reviewed, 2018)Isolation of habitats in space and time affects species globally and in a multitude of ecosystems. It is however often difficult to assess the level of isolation from the point of view of the focal species. Indicator species ... -
Fitness and fur colouration: Testing the camouflage and thermoregulation hypotheses in an Arctic mammal
Di Bernardi, Cecilia; Thierry, Anne-Mathilde; Eide, Nina Elisabeth; Bowler, Diana Elizabeth; Rød-Eriksen, Lars; Blumentrath, Stefan; Tietgen, Lukas; Sandercock, Brett; Flagstad, Øystein; Landa, Arild (Peer reviewed; Journal article, 2021)1. Selection for crypsis has been recognized as an important ecological driver of animal colouration, whereas the relative importance of thermoregulation is more contentious with mixed empirical support. A potential thermal ... -
Freshwater Fish Community Responses to Climate Change and Invasive Species
Perrin, Sam Wenaas (Doctoral theses at NTNU;2021:27, Doctoral thesis, 2021)Despite making up only a tiny proportion of the world’s aquatic surface area, freshwater ecosystems are home to a plethora of biodiversity, containing roughly 40% of all described fish species. Yet they’re also among the ... -
From greening to browning: Catchment vegetation development and reduced S-deposition promote organic carbon load on decadal time scales in Nordic lakes
Finstad, Anders Gravbrøt; Andersen, Tom; Larsen, Søren; Tominaga, Koji; Blumentrath, Stefan; de Wit, Heleen; Tømmervik, Hans; Hessen, Dag Olav (Journal article; Peer reviewed, 2016)Increased concentrations of dissolved organic carbon (DOC), often labelled “browning”, is a current trend in northern, particularly boreal, freshwaters. The browning has been attributed to the recent reduction in sulphate ... -
Integrating dispersal along freshwater ecosystems into species distribution models
Perrin, Sam Wenaas; Englund, Göran; Blumentrath, Stefan; O'Hara, Robert Brian; Amundsen, Per-Arne; Finstad, Anders Gravbrøt (Journal article; Peer reviewed, 2020)Aim: Our ability to model species distributions and abundances is a valuable ecological tool in predicting future distributions of species. Effectively incorporating connectivity into these predictions is crucial; however, ...
