Abstract In the Barents Sea, strong top predator responses to repeated stock collapses of the forage fish capelin Mallotus villosus have been observed. The white-beaked dolphin Lagenorhynchus albirostris, a flexible predator with a diverse diet in other marine systems, has been associated with capelin in the Barents Sea. Yet, their distribution and foraging ecology in this ecosystem remain largely unknown. Here we use synoptically collected dolphin and prey spatial data to investigate the… 
Fin whale ( Balaenoptera physalus ) distribution modeling on their Nordic and Barents Seas feeding grounds
Understanding cetacean distribution is essential for conservation planning and decision-making, particularly in regions subject to rapid environmental changes. Nevertheless, information on their
Using a new framework of two-phase generalized additive models to incorporate prey abundance in spatial distribution models of juvenile slender lizardfish in Haizhou Bay, China
A new framework of two-phase generalized additive models based on the Tweedie distribution is developed to incorporate the predicted prey abundance as covariates in habitat models to improve the predictive skill of habitat models and enhance the understanding of the ecological mechanisms underlying the distribution of marine species.
Lagenorhynchus albirostris (Cetacea: Delphinidae)
A robustly built dolphin with black, white, and gray coloration, L. albirostris has a whitish beak, a prominent dorsal fin, and a white saddle behind the fin.
Impacts of climate change on marine mammals, relevant to the coastal and marine environment around the UK
• The main observed effects of climate change on marine mammals globally have been geographical range shifts and loss of habitat through ice cover loss, changes to the food web, increased exposure to

Cetacean spatial trends from 2005 to 2019 in Svalbard, Norway
This study uses cetacean sighting data, acquired via a citizen science programme, to update distributions and spatial trends of whales and dolphins in waters around the Svalbard Archipelago during
Determining the species assemblage and habitat use of cetaceans in the Svalbard Archipelago, based on observations from 2002 to 2014
ABSTRACT This study used 13 years of cetacean sighting data (2002–2014) from waters around the Svalbard Archipelago to determine key habitats for year-round resident species as well as seasonally


Baleen whale distributions and prey associations in the Barents Sea
Ecosystem-scale associations indicated that krill was the predominant prey species in the Barents Sea in this season, but contrasting mesoscale associations with their prey in 50 km grid cells and a preference for shallow northern banks suggests that these whales have a diverse diet within a pre- ferred habitat.
Trophic ecology of blue whiting in the Barents Sea
The importance of blue whiting as prey for predatory fish was highest in the areas of greatest abundance, but overall,blue whiting were seemingly unimportant as prey of piscivorous fish in the Barents Sea.
Feeding in a heterogeneous environment: spatial dynamics in summer foraging Barents Sea cod
Analysis of spatial aspects of cod−prey interactions in the Barents Sea during recent warm years implies that the cod were spatially constrained and that their prey differed in suitability.
Status of the White-beaked Dolphin, Lagenorhynchus albirostris, in Canada
There is no evidence of any major threat to this species in zones under Canadian jurisdiction, however, careful monitoring of hunting activities in Labrador is recommended and fisheries by-catches should be carefully monitored.
This work presents evidence for a hierarchical spatial distribution of murres (Uria spp.) foraging on capelin (Mallotus villosus) in the Barents Sea and suggests that murres use a strategy where the search pattern reflects the hierarchical properties of the prey system.
Are white-beaked dolphins Lagenorhynchus albirostris food specialists? Their diet in the southern North Sea
The overall diet showed a lasting predominance of whiting and cod, without clear changes over time (35 years) or differences between sexes or size-classes of dolphins, with Gadidae dominating the diet on both sides of the Atlantic.
Seasonal distribution of white-beaked dolphins (Lagenorhynchus albirostris) in UK waters with new information on diet and habitat use
Details of the seasonal and geographical distribution of white-beaked dolphins around the UK are presented, along with new information on their diet and habitat use, and analysis of historical stranding records shows a segregation of the sexes.
Spatial interaction between seabirds and prey: review and synthesis
This study reviews recent theoretical advances in spatial predator-prey interactions and relates these with studies of seabirds and pelagic schooling fish and crustaceans to find the unstable local dynamics might be stabilized by spatial constraints and the effects of ARS processes at large scales.
Hydrographic features, cetaceans and the foraging of thick-billed murres and other marine birds in the northwestern Barents Sea
A positive association was found between the abundance of murres and the occurrence of cetaceans, and Murre aggregations were associated with frontal zones between cold Arctic waters and warmer Atlantic water, and in areas with strong stratification in salinity.
The importance of scale to predator-prey spatial correlations: an example of Atlantic fishes
The signs and strengths of spatial correlations between densities of predators and their prey were scale dependent both in simulations and when calculated from acoustic transects across nearshore
