(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
Colored dissolved organic matter (CDOM) absorbs a substantial fraction of photosynthetically active radiation (PAR) in boreal lakes. However, few studies have systematically estimated how this light absorption influences ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
Boreal lakes are important net sources of greenhouse gases (GHGs). In this study we analyzed concentrations of CO2, CH4, N2O as well as O2, N2 and argon (Ar) from the epilimnion of 75 boreal lakes covering gradients in ...
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
Concentrations of dissolved organic matter (DOM) are increasing in a large number of lakes across the Northern hemisphere. This browning serves a dual role for biota by protecting against harmful ultraviolet radiation, ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
Temperature and nutrients are key factors affecting the growth, cell size, and physiology of marine phytoplankton. In the ocean, temperature and nutrient availability often co-vary because temperature drives vertical ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
There is growing empirical and theoretical evidence for a positive relationship between the nitrogen (N)‐to‐phosphorus (P) ratio of phytoplankton and temperature. However, few have tested how the optimal supply N:P ratio; ...

1. Lakes worldwide are in rapid change because of direct or indirect climate impacts. In boreal areas, the increased concentrations of dissolved organic matter (DOM) are profoundly affecting light climate and productivity ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
In recent decades, the freshwater alga Gonyostomum semen (Ehrenberg) Diesing has increased in abundance and distribution, which has created problems regarding the use of lakes for drinking water and recreation. Increases ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Covariation in species richness and community structure across taxonomical groups (cross‐taxon congruence) has practical consequences for the identification of biodiversity surrogates and proxies, as well as theoretical ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
Many boreal lakes are experiencing an increase in concentrations of terrestrially derived dissolved organic matter (DOM)—a process commonly labeled “browning.” Browning affects microbial and photochemical mineralization ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
The Gauss-peak spectra (GPS) method represents individual pigment spectra as weighted sums of Gaussian functions, and uses these to model absorbance spectra of phytoplankton pigment mixtures. We here present several ...
