The occurrence of biomineralisation products in four lichen species growing on sandstone in western Norway
(Peer reviewed; Journal article, 2002)High performance thin-layer chromatography/thin-layer chromatography, X-ray diffraction, and scanning electron microscopy analysis of thallus and lichen-rock interface samples, were undertaken to characterize biomineralization ... -
Occurrence of salmonid alphavirus and piscine orthoreovirus-1 infections in migrating salmon (Salmo salar L.) post-smolt in western Norway
(Journal article; Peer reviewed, 2023)Viral diseases are a serious problem in Atlantic salmon (Salmo salar L.) farming in Norway, often leading to reduced fish welfare and increased mortality. Disease outbreaks in salmon farms may lead to spread of viruses to ... -
The occurrence, pathology and morphological development of Paranucleospora theridion in salmon louse (Lepeophtheirus salmonis)
(Master thesis, 2012-06-04)In 2003 a microsporidian parasite was discovered in salmon lice (Lepeophtheirus salmonis). The same parasite was later described from Atlantic salmon (Salmo salar) and salmon lice and was identified as Paranucleospora ... -
Ocean literacy and surfing: Understanding how interactions in coastal ecosystems inform blue space user’s awareness of the ocean
(Journal article; Peer reviewed, 2021-05-28)Intergovernmental policy is targeting public ocean literacy to help achieve the societal changes needed to reach a sustainable ocean agenda within a 10-year timeframe. To create a culture of care for the ocean, which is ... -
The ocean sampling day consortium
(Peer reviewed; Journal article, 2015-06-19)Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. ... -
Oceanographic connectivity explains the intra-specific diversity of mangrove forests at global scales
(Journal article; Peer reviewed, 2023)The distribution of mangrove intra-specific biodiversity can be structured by historical demographic processes that enhance or limit effective population sizes. Oceanographic connectivity (OC) may further structure ... -
Of tests, trochs, shells, and spicules: Development of the basal mollusk Wirenia argentea (Solenogastres) and its bearing on the evolution of trochozoan larval key features
(Peer reviewed; Journal article, 2010-01-26)Background The phylogenetic status of the aplacophoran mollusk taxon Solenogastres (Neomeniomorpha) is controversially discussed. Some authors propose the clade to represent the most basal branch within Mollusca, while ... -
OikoBase: a genomics and developmental transcriptomics resource for the urochordate Oikopleura dioica
(Peer reviewed; Journal article, 2013-11-26)We report the development of OikoBase (http://oikoarrays.biology.uiowa.edu/Oiko/), a tiling array-based genome browser resource for Oikopleura dioica, a metazoan belonging to the urochordates, the closest extant group to ... -
The Okavango Delta: Fisheries in a fluctuating floodplain system
(Journal article; Peer reviewed, 2022)Wetlands are among the most productive ecosystems globally characterized by dynamic interactions between terrestrial and aquatic habitats at different scales. These systems support valuable floodplain fisheries that are a ... -
On a hexactinellid sponge aggregation at the Great Meteor seamount (North-east Atlantic)
(Peer reviewed; Journal article, 2015-11)Hexactinellids or glass sponges constitute a predominantly deep-sea sponge group typically occurring at bathyal and abyssal depths. Some species form dense populations along the European and African continental slope but ... -
On giant shoulders: how a seamount affects the microbialcommunity composition of seawater and sponges
(Journal article; Peer reviewed, 2020)Seamounts represent ideal systems to study the influence and interdependency of environmental gradients at a single geographic location. These topographic features represent a prominent habitat for various forms of life, ... -
On the chemistry, toxicology and genetics of the cyanobacterial toxins, microcystin, nodularin, saxitoxin and cylindrospermopsin
