A comprehensive evaluation of predictive performance of 33 species distribution models at species and community levels
(Journal article; Peer reviewed, 2019)A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages. Given the wealth of existing models, it is unclear ... -
Per- and poly-fluoroalkyl substances in Tawny Owl (Strix aluco) feathers from Trøndelag, Norway
(Journal article; Peer reviewed, 2023)Per- and polyfluoroalkyl substances (PFASs) are contaminants of global concern due to their ubiquitous occurrence in the environment, bioaccumulation and the adverse effects on organisms. Tawny Owls (Strix aluco) are ... -
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validation
(Journal article; Peer reviewed, 2023)Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reli-ability of those predictions, they need to be critically ... -
Subclinical thiamine deficiency results in failed reproduction in Arctic foxes
(Peer reviewed; Journal article, 2024)Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ... -
Multi-generation genetic and fitness effects of immigration in a natural meta-population of song sparrows (Melospiza melodia)
(Doctoral theses at NTNU;2024:105, Doctoral thesis, 2024)Fragmentation leads to smaller habitat patches and population sizes, endangering population fitness and persistence, including through inbreeding depression and loss of genetic diversity. These effects can be mitigated ... -
Long-term dynamics, population structure and connectivity of the helmet jellyfish Periphylla periphylla in a Norwegian fjord and adjacent waters
(Journal article; Peer reviewed, 2023)Mass occurrences of Periphylla periphylla in Norwegian fjords cause major concerns related to potential regime shifts that could affect ecosystem stability. 15 years of trawl data (2006–2015), complemented with comprehensive ... -
Notes on Early Land Plants Today. 84. Cheilolejeunea solariae, nom. nov. for Strepsilejeunea subcrenulata Herzog
(Peer reviewed; Journal article, 2023)Grolle (1989) united Strepsilejeunea subcrenulata Herzog with the younger name Cheilolejeunea papillata Solari. However, transferring the former name to Cheilolejeunea was blocked by the existence of the earlier name ... -
Notes on Early Land Plants Today. 83. Re-instatement of Lejeunea parvisaccata
(Peer reviewed; Journal article, 2023)Mizutani (1970) introduced a new name, Lejeunea micholitzii Mizut., when transferring Hygrolejeunea parvisaccata Steph. to Lejeunea Lib. since Lejeunea parvisaccata (Steph.) Steph. was blocking the name in Lejeunea. The ... -
Ecological signals of arctic plant-microbe associations are consistent across eDNA and vegetation surveys
(Peer reviewed; Journal article, 2023)Understanding how different taxa respond to abiotic characteristics of the environment is of key interest for understanding the assembly of communities. Yet, whether eDNA data will suffice to accurately capture environmental ... -
Monitoring regional benthic environment of Norwegian salmon cage farms
(Peer reviewed; Journal article, 2024)The influence of cage aquaculture on the benthic environment is a crucial concern for sustainable development. The impacts are affected by multiple environmental factors and aquaculture operations. Our main objective was ... -

TFCheckpoint database update, a cross-referencing system for transcription factors from human, mouse and rat
(Journal article; Peer reviewed, 2023)Prior knowledge about DNA-binding transcription factors (dbTFs), transcription co-regulators (coTFs) and general transcriptional factors (GTFs) is crucial for the study and understanding of the regulation of transcription. ... -
Molecular quantification of parasitic sea louse larvae depends on species and life stage
(Peer reviewed; Journal article, 2023)Sea lice cause substantial economic and environmental harm to Norway's aquacul-ture industry and wild salmonid populations. Rapid, accurate quantification of lice larval densities in coastal waters remains the greatest ... -
Alternative measures of trait–niche relationships: A test on dispersal traits in saproxylic beetles
(Journal article; Peer reviewed, 2023)Functional trait approaches are common in ecology, but a lack of clear hypotheses on how traits relate to environmental gradients (i.e., trait–niche relationships) often makes uncovering mechanisms difficult. Furthermore, ... -
Notes on Early Land Plants Today. 85. Metzgeria warnstorffii, an earlier name for the African Metzgeria madagassa
(Journal article; Peer reviewed, 2023)Kuwahara (1984) synonymized Metzgeria madagassa Steph. and Metzgeria thomeensis Steph. under the name Metzgeria australis Steph. So (2004) rejected this synonymy and recognized Metzgeria madagassa from Africa (excluding ... -
Slicing: A sustainable approach to structuring samples for analysis in long‐term studies
(Peer reviewed; Journal article, 2020)The longitudinal study of populations is a core tool for understanding ecological and evolutionary processes. Long-term studies typically collect samples repeatedly over individual lifetimes and across generations. These ... -

Species delimitation and phylogenetic relationships of the Prionospio complex (Annelida, Spionidae) in the Northeast Atlantic
(Peer reviewed; Journal article, 2024)The Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. ... -
