Demersal assemblages of the continental shelf and upper slope of Angola
(Journal article; Peer reviewed, 1992-04-21)The structure of the demersal assemblages (fish, crustaceans and cephalopods) of the continental shelf and upper slope of Angola (ca 5 to 17-degrees-S) was studied based on the trawl survey of the RV `Dr. Fridtjof Nansen' ... -
Demersal Fish Assemblages and Spatial Diversity Patterns in the Arctic-Atlantic Transition Zone in the Barents Sea
(Journal article; Peer reviewed, 2012-04-17)Direct and indirect effects of global warming are expected to be pronounced and fast in the Arctic, impacting terrestrial, freshwater and marine ecosystems. The Barents Sea is a high latitude shelf Sea and a boundary area ... -
Demersal fish assemblages in the boreo-Arctic shelf waters around Svalbard during the warm period 2007–2014
(Peer reviewed; Journal article, 2017)The temporal and spatial resilience of abundance patterns of assemblages of organisms inhabiting transition zones between Arctic and boreal regions is an issue of concern in relation to climate change. The recognition that ... -
Demographic history has shaped the strongly differentiated corkwing wrasse populations in Northern Europe.
(Journal article; Peer reviewed, 2019)Understanding the biological processes involved in genetic differentiation and divergence between populations within species is a pivotal aim in evolutionary biology. One particular phenomenon that requires clarification ... -
Demographic responses to protection from harvesting in a long-lived marine species
(Peer reviewed; Journal article, 2021)Marine protected areas (MPAs) are usually considered to have positive effects on the recovery of over-exploited populations. However, resolving the extent to which MPAs function according to their conservation goals requires ... -
Dense mesopelagic sound scattering layer and vertical segregation of pelagic organisms at the Arctic-Atlantic gateway during the midnight sun
(Peer reviewed; Journal article, 2021)Changes in vertical and spatial distributions of zooplankton and small pelagic fish impact the biological carbon pump and the distribution of larger piscivorous fish and marine mammal species. However, their distribution ... -
Density regulation in Northeast Atlantic fish populations: Density dependence is stronger in recruitment than in somatic growth
(Journal article; Peer reviewed, 2018) -
Density-dependent growth as a key mechanism in the regulation of sh populations: evidence from among-population comparisons
(Journal article; Peer reviewed, 2001-11-30)It is generally assumed that fish populations are regulated primarily in the juvenile (pre-recruit) phase of the life cycle, although density dependence in growth and reproductive parameters within the recruited phase has ... -
Density-dependent migratory waves in the marine pelagic ecosystem
(Journal article; Peer reviewed, 2006-11)The migration of large aggregations of animals that sweep through the landscape is a phenomenon with large consequences in many ecosystems. It has been suggested that such migrations are mediated by resource depletion. ... -
Density-independent mortality at early life stages increases the probability of overlooking an underlying stock-recruitment relationship
(Peer reviewed; Journal article, 2021)Abstract Beverton and Holt’s (1957) monograph contributed a widely used stock–recruitment relationship (BH-SRR) to fisheries science. However, because of variation around a presumed relationship between spawning biomass ... -
Density‐ and size‐dependent mortality in fish early life stages
(Journal article; Peer reviewed, 2019)The importance of survival and growth variations early in life for population dynamics depends on the degrees of compensatory density dependence and size dependence in survival at later life stages. Quantifying density‐ ... -
Depletion of coastal predatory fish sub-stocks coincided with the largest sea urchin grazing event observed in the NE Atlantic
(Peer reviewed; Journal article, 2020)In this contribution, we propose fishery driven predator release as the cause for the largest grazing event ever observed in the NE Atlantic. Based on the evolving appreciation of limits to population connectivity, published ... -
Depth and latitudinal gradients of diversity in seamount benthic communities
(Peer reviewed; Journal article, 2022)Latitudinal and bathymetric species diversity gradients in the deep sea have been identified, but studies have rarely considered these gradients across hard substratum habitats, such as seamount and oceanic island margins. ... -
Depth distribution of the amoebic gill disease agent, Neoparamoeba perurans, in salmon sea-cages
(Journal article; Peer reviewed, 2015-07-16)Identifying where and when parasites occur in farming environments is vital to understand transmission dynamics and develop preventative measures that reduce host-parasite encounters. A major parasite concern for Atlantic ... -
Depth-dependent target strengths of gadoids by the boundary-element method
(Journal article; Peer reviewed, 2003)The depth dependence of fish target strength has mostly eluded experimental investigation because of the need to distinguish it from depth-dependent behavioral effects, which may change the orientation distribution. The ... -
Deriving condition indices from standard fisheries databases and evaluating their sensitivity to variation in stored energy reserves
(Journal article; Peer reviewed, 2004)To evaluate interstock differences in condition, it would be advantageous to develop stock-level condition indices from standardized databases on weight and length. This study describes a method for estimating stock-level ... -
Descent and mixing of the overflow plume from Storfjord in Svalbard: an idealized numerical model study
(Journal article; Peer reviewed, 2008)Storfjorden in the Svalbard Archipelago is a sill-fjord that produces significant volumes of dense, brine-enriched shelf water through ice formation. The dense water produced in the fjord overflows the sill and can reach ... -
Description of a new goatfish species, Upeneus randalli n. sp. (Mullidae), from the Persian Gulf, with remarks and identification keys for the genus Upeneus
(Journal article; Peer reviewed, 2011-09)The number of species of the goatfish genus Upeneus from the western Indian Ocean has increased considerably due to recent taxonomic efforts. Here we describe a new species, Upeneus randalli n. sp., based on body and fin ... -
Description of the unusual digestive tract of Platax orbicularis and the potential impact of Tenacibaculum maritimum infection
(Peer reviewed; Journal article, 2020)Ephippidae fish are characterized by a discoid shape with a very small visceral cavity. Among them Platax orbicularis has a high economic potential due to its flesh quality and flesh to carcass ratio. Nonetheless, the ... -
Designing and evaluating length–frequency surveys for trap fisheries with application to the southern rock lobster
(Journal article; Peer reviewed, 2001)A survey design for estimating the length distribution of harvested southern rock lobsters (Jasus edwardsii) was developed for the South Australian fishery. Experimental sampling was carried out by volunteer fishers in ...
