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, ... -
Viewshed-based modelling of visual exposure to urban greenery – An efficient GIS tool for practical planning applications
Cimburova, Zofie; Blumentrath, Stefan (Peer reviewed; Journal article, 2022)Quantifying green visual exposure is necessary to assess aesthetic, social and health benefits from urban greenery. Viewshed analysis has been successfully used to model and map green visual exposure from human perspective ...
