On the origin of bird's nest fungi: Phylogenomic analyses of fungi in the Nidulariaceae (Agaricales, Basidiomycota)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-07)Nidulariaceae, also known as bird’s nest fungi, is an understudied group of mushroom-forming fungi. The common name is derived from their nest-like morphology. Bird’s nest fungi are ubiquitous wood decomposers or saprobes on dung. Recent studies showed that species in the Nidulariaceae form a monophyletic group with five sub-clades. However, phylogenetic relationships among genera and placement ... -
Bioprospecting of inhibitors of EPEC virulence from metabolites of marine actinobacteria from the Arctic Sea
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-08-30)A considerable number of antibacterial agents are derived from bacterial metabolites. Similarly, numerous known compounds that impede bacterial virulence stem from bacterial metabolites.

These infections are characterized by microvilli ... -
Efficient and sustainable: innovative pot design for a Mediterranean small-scale fishery
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-28)Pots are traditional fishing gear type largely employed in Mediterranean Small Scale Fisheries (SSFs). Their often higher species selectivity and catch quality compared to other gear types such as passive set nets or trawls are appealing characteristics for reducing the impact on benthic communities and diversifying fishing effort in the region. Despite this, in some SSFs, pots are still rarely used ... -

Noise pollution from Arctic expedition cruise vessels: understanding causes, consequences and governance options
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-10)Significant increase in shipping in the Arctic has caught international and national attention. The rising presence of touristic expedition cruise vessels might describe a special case for noise as a marine pollutant while they seek exclusive opportunities to experience the Arctic first-hand. This interdisciplinary study develops a conceptual framework to investigate context-specific vessel ... -
Size selectivity of flatfish in trawl codends
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-28)Flatfish constitute a substantial proportion of the catch in several demersal trawl fisheries across the globe. Therefore, knowledge on how to discriminate between the individuals that are to be captured or released, by size, is important for the sustainability of exploited stocks. Using European plaice (Pleuronectes platessa), flounder (Platichthys flesus), and dab (Limanda limanda) as ... -

Leaving the niche: Recommendations for mainstreaming Low Trophic Aquaculture in countries around the Atlantic basin
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-01)Low Trophic Aquaculture (LTA) is the farming of aquatic organisms such as primary producers (e.g., seaweeds) and primary consumers (e.g. bivalves). Despite recognition as a key pathway to the provision of sustainable food from the oceans, many forms of LTA around the Atlantic basin remain in the niche stage of socio-technical evolution. With governance regarded as a limiting factor to LTA development, ... -
Can pots be an alternative fishing gear to gillnets? A Mediterranean case study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-12)Small-scale coastal fisheries in the Mediterranean often employ gillnets, a widely used gear worldwide. The disadvantages of gillnets in this fishery include high bycatch levels of unwanted species and consequent discards. Moreover, spatial conflict with other gears and dolphin depredation often results in considerable economic loss. Alternative fishing methods are being tested. This study investigated ... -
Can automatic measuring replace humans when evaluating a shrimp fishery?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-05)Size measurements of fish and crustacean species play a critical role in fishery stock assessments, fishing gear size selectivity studies, and monitoring compliance with fisheries management regulations. One such example is from shrimp fisheries where samples of trawl-caught shrimps are frequently collected and size measured. However, the manual measurement of hundreds of small shrimps per sample ... -
The microbiome of bioreactors containing mass-cultivated marine diatoms for industrial carbon capture and utilization
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-10)Marine microalgae are a promising innovation platform for carbon capture and utilization (CCU) biotechnologies to mitigate industrial greenhouse gas emissions. However, industrial-scale cultivation of algal mono-cultures is challenging and often unscalable. Non-axenic microalgae in large semi-open photobioreactors lead to the co-cultivation of diverse microbial communities. There is limited knowledge ... -
