Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Vanessa Bettcher Brito, Amanda Batlle-Morera, Peter M. Kyne, Ryan J. Charles et autres

Climate-driven alterations in sea-ice dynamics and shifting fishing activity are reshaping ecosystems across the Arctic and Antarctic, yet conservation-relevant information for chondrichthyans (sharks, rays, and chimaeras) remains limited. We present the first assessment of Important Shark and Ray Areas (ISRAs) across Polar …

Importance of capelin in the diet of Barents Sea predators relative to alternative prey

Joël M. Durant, Øystein Langangen, Andrey V. Dolgov, Ulf Lindstrøm et autres

The Arcto-boreal Barents Sea is significantly impacted by temperature warming, with potential effects on trophic interactions and population dynamics. Capelin, a small pelagic fish species, dominates the Barents Sea’s relatively simple food web. Capelin are an essential link between lower trophic levels …

Biogeographic Changes in a High Latitude Marine Fish Community: Short‐Time Reversals in Response to Climate Variation

Kari Elsa Ellingsen, Andrey V. Dolgov, Kenneth T. Frank, Edda Johannesen et autres

ABSTRACT Aim Determine whether changes in fish biogeographic composition and key facets of biodiversity are reversible at short time scales in a high latitude marine ecosystem experiencing ocean warming in the context of a recent short‐term cooling, and an increasing then declining …

The living Barents Sea response to peak-warming and subsequent cooling

Elena Eriksen, Bérengère Husson, Georg Skaret, Randi B. Ingvaldsen et autres

The Arctic warms nearly four times faster than the global average, with maximum warming in the Barents Sea. Concurrently, changes in species distribution in this productive and highly exploited sub-Arctic hotspot has been found. However, studies so far have mostly focused on …

Diet and trophic structure of fishes in the Barents Sea: between empty and full stomachs – large individual variability follows a common pattern

Hein Rune Skjoldal, Elena Eriksen, Kotaro Ono, Andrey V. Dolgov

Abstract More than 27,000 stomachs from 70 species of fish were collected from the Barents Sea in 2015. Quantitative stomach content expressed relative to the body weight of the predator fish (g g −1 as %) varied by four to five orders …

Zooplankton link climate to capelin and polar cod in the Barents Sea

Padmini Dalpadado, Irina P. Prokopchuk, Bjarte Bogstad, Georg Skaret et autres

Capelin (Mallotus villosus) and polar cod (Boreogadus saida) hold a fundamental position in the Barents Sea ecosystem as consumers of zooplankton while serving as forage fish for the commercial and ecological key species Atlantic cod (Gadus morhua). The ongoing warming and Atlantification …

Diet and trophic structure of fishes in the Barents Sea: Effects of size within (ontogenetic) and between species

Elena Eriksen, Hein Rune Skjoldal, Kotaro Ono, Andrey V. Dolgov

A large data set on stomach content (over 27,000 individual fish) – collected in the Barents Sea in 2015 – was used to examine ontogenetic and interspecific changes in diet with size for 35 fish species. The analysis combined the use of …
