Harvest control rules in modern fisheries management
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-20)
Harvest control rules have become an important tool in modern fisheries management, and are increasingly adopted to provide continuity in management practices, to deal with uncertainty and ecosystem considerations, and to relieve management decisions from short-term political pressure. We provide the conceptual and institutional background for harvest control rules, a discussion of the structure of ...
Representations of Colonialism in Three Popular, Modern Board Games: Puerto Rico, Struggle of Empires, and Archipelago
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-10)
With all its intricate processes, colonialism, both as an ideology and a historical period, has been a rich source of inspiration for contemporary popular culture, whether in the form of movies, novels, digital games, or analogue games. This article presents a critical analysis of colonial representations in three examples of the latter: <i>Puerto Rico</i> (2002), <i>Struggle of Empires</i> (2004), ...
What hat are you wearing? On the multiple roles of fishery scientists in the ICES community
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-29)
Trends towards a more participatory agenda in policy-relevant science imply that the roles and work tasks of scientists become more multifaceted. In Europe, the increased use of multiannual plans creates a need for fishery scientists to contribute with their expertise in a wide variety of situations. We identify and characterize four roles for scientists as <i>developers</i>, <i>reviewers</i>, ...
Polygenic selection drives the evolution of convergent transcriptomic landscapes across continents within a Nearctic sister species complex
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-03)
In contrast to the plethora of studies focusing on the genomic basis of adaptive phenotypic divergence, the role of gene expression during speciation has been much less investigated and consequently less understood. Yet, the convergence of differential gene expression patterns between closely related species‐pairs might reflect the role of natural selection during the process of ecological speciation. ...
A Novel Brominated Alkaloid Securidine A, Isolated from the Marine Bryozoan Securiflustra securifrons
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-23)
A novel brominated alkaloid, Securidine A, was isolated from the cold water marine bryozoan Securiflustra securifrons. Securidine A was isolated using semi-preparative HPLC, and the structure was elucidated by spectroscopic methods. The isolated Securidine A was tested for cytotoxic, antibacterial, and anti-diabetic activities as well as for its potential for inhibition of biofilm formation. No ...
Carbon, Nitrogen and Sulphur isotopic fractionation in captive juvenile hooded seal (Cystophora cristata): application for diet analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-15)
<p><i>Rationale</i>: Intrinsic biogeochemical markers, such as stable isotope ratios of carbon, nitrogen and sulphur, are increasingly used to trace the trophic ecology of marine top predators. However, insufficient knowledge of fractionation processes in tissues continues to hamper the use of these markers.</p>
<p><i>Methods</i>: We performed a controlled feeding experiment with eight juvenile ...
Cold seawater induces early sexual developmental stages in the BPG axis of European eel males
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)
<i>Background</i>: The impossibility of closing the life cycle of the European eel (<i>Anguilla anguilla</i>) in captivity troubles the
future of this critically endangered species. In addition, the European eel is a highly valued and demanded resource,
thus the successful closing of its life cycle would have a substantial economic and ecological impact. With the aim of
obtaining the highest ...
Fish silage hydrolysates: Not only a feed nutrient, but also a useful feed additive
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-06)
Background:<br>
Processing of fish and shellfish may result in substantial amounts of by-products and unless they can be used as food, the most realistic option in most cases is the production of preserved feed nutrients. If large volumes are available, reduction to fishmeal and fish oil is the preferred technology. However, fresh by-products are most often available in insufficient quantities ...
The effect of algae diets (Skeletonema costatum and Rhodomonas baltica) on the biochemical composition and sensory characteristics of Pacific cupped oysters (Crassostrea gigas) during land-based refinement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-20)
<p>Oyster refinement, a common practice in France, is aimed at increasing the weight of oyster tissue and influencing the taste properties of the refined oysters. Refinement usually takes place in land-based systems where the oysters are fed with relatively high concentrations of microalgae. In this study the impact of feeding <i>Skeletonema costatum</i> and <i>Rhodomonas baltica</i> on the biochemical ...
Seasonal and yearly variation of total polyphenols, total anthocyanins and ellagic acid in different clones of cloudberries (Rubus chamaemorus L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-02)
Cloudberry (Rubus chamaemorus L.) is a wild perennial shrub growing on peatland with a circumpolar distribution. The combined berries have a high polyphenol content comprised primarily of ellagitannins. A few commercial cultivars are available, and pre-breeding trials on clonal material from different geographical origins are in progress. The objective of this study was to investigate how the content ...
