The Demographic buffering hypothesis: Evidence and challenges
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06)In (st)age-structured populations, the long-run population growth rate is negatively affected by temporal variation in vital rates. In most cases, natural selection should minimize temporal variation in the vital rates to which the long-run population growth is most sensitive, resulting in demographic buffering. By reviewing empirical studies on demographic buffering in wild populations, we found ... -
Simulated trawling: Exhaustive swimming followed by extreme crowding as contributing reasons to variable fillet quality in trawl-caught Atlantic cod (Gadus morhua)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-18)Trawl-caught Atlantic cod (Gadus morhua) often yield highly variable fillet quality that may be related to capture stress. To investigate mechanisms involved in causing variable quality, commercial-sized (3.5±0.9 kg) Atlantic cod were swum to exhaustion in a large swim tunnel and subsequently exposed to extreme crowding (736±50 kg m<sup>-3</sup>) for 0, 1 or 3 hours in an experimental cod-end. The ... -
Car tire crumb rubber: Does leaching produce a toxic chemical cocktail in coastal marine systems?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-23)Crumb rubber granulate (CRG) produced from end of life tires (ELTs) is commonly applied to synthetic turf pitches (STPs), playgrounds, safety surfaces and walkways. In addition to fillers, stabilizers, cross-linking agents and secondary components (e.g., pigments, oils, resins), ELTs contain a range of other organic compound and heavy metal additives. While previous environmental impact studies on ... -
New approach for modelling size selectivity in shrimp trawl fisheries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-10)In the deep sea trawl fishery targeting shrimp (Pandalus borealis) and other cold-water shrimp species, fishers often use a Nordmöre sorting grid ahead of a small mesh codend to avoid bycatch. However, small fish can pass through the grid and are subsequently retained in the codend. This makes shrimp size selection complex and the size-dependent curve for both the shrimp and the bycatch species often ... -
Measured sound levels in ice-covered shallow water caused by seismic shooting on top of and below floating ice, reviewed for possible impacts on true seals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-01)Seismic surveying of the Arctic is important for several reasons, but also introduces some challenges. One is the concern that seismic data may affect the hearing of marine mammals living there, including true seals. We performed two seismic experiments on floating ice on Svalbard in the Norwegian Arctic in early March 2016 and late May 2017, just before and right after the ringed seal breeding ... -
Kvalitetskrav for vann til jordvanning. Uttalelse fra Faggruppen for hygiene og smittestoffer i Vitenskapskomiteen for mattrygghet
(Research report; Forskningsrapport, 2014-05-07)Ved vanning av spiselige jordbruksvekster på friland i Norge brukes det overflatevann, grunnvann eller vann fra gravd brønn. Vannet kan være offentlig eller privat. Mikroorganismer og uønskede kjemiske stoffer i slikt vann kan forårsake sykdom, dersom dette benyttes til vanning av vegetabiler. For sykdomsfremkallende mikroorganismer gjelder dette spesielt ved vanning av vegetabiler som skal spises ... -
Does the efficiency of a counter-herding device depend on seabed contact?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-06)To prevent unwanted fish bycatch from entering the trawl, we modified a counter-herding device, FLEXSELECT, developed for a Northeast Atlantic <i>Nephrops</i> (<i>Nephrops norvegicus</i>) trawl fishery. FLEXSELECT, which was designed to direct fish away from the trawl by means of sweeping ropes in the herding area, has been shown to be highly effective on both roundfish and flatfish species. However, ... -
Synergism between cruising cod and ambush sculpin predators on 0-group gadoids is modified by daylight cycle and presence of aggressive wolffish
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-06)Shorthorn sculpin (<i>Myoxocephalus scorpius</i>) and large cod (300–400 g body weight) are important predators on newly settled 0-group cod (<i>Gadus morhua</i>) and saithe (<i>Pollachius virens</i>) in Porsangerfjorden in northern Norway. The Atlantic wolffish (<i>Anarhichas lupus</i>) used to be abundant but is now very rare in the fjord. Video recorded experiments showed that interactions between ... -
“And if you gaze long into an abyss, the abyss gazes also into thee ”: four morphs of Arctic charr adapting to a depth gradient in Lake Tinnsjøen
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-24)The origin of species is a central topic in biology. Ecological speciation might be a driver in adaptive radiation, providing a framework for understanding mechanisms, level, and rate of diversification.
