Demersal fish biomass declines with temperature across productive shelf seas [PDF]

Global Ecology and Biogeography, Volume 32, Issue 10, Page 1846-1857, October 2023., 2023
Aim: Theory predicts fish community biomass to decline with increasing temperature due to higher metabolic losses resulting in less efficient energy transfer in warm-water food webs.

Reduced-Representation Sequencing Detects Trans-Arctic Connectivity and Local Adaptation in Polar Cod (Boreogadus saida). [PDF]

Mol Ecol
ABSTRACT Information on connectivity and genetic structure of marine organisms remains sparse in frontier ecosystems such as the Arctic Ocean. Filling these knowledge gaps becomes increasingly urgent, as the Arctic is undergoing rapid physical, ecological and socio‐economic changes.

Contribution of hybridization between polar bears and grizzly bears to polar bear extinction 北极熊和灰熊的杂交对北极熊灭绝的促进

Wildlife Letters, Volume 1, Issue 4, Page 178-193, December 2023., 2023
Genetic analysis by scientists of hybridization events from 2006 to 2010 indicates one‐directional gene flow from polar bears to grizzly bears. Even if gene flow was later discovered from grizzly bears to polar bears, there is not enough time to allow for significant adaptation to a rapidly changing Arctic environment.

Caribbean Marine Heatwaves, Marine Cold Spells, and Co‐Occurrence of Bleaching Events

Journal of Geophysical Research: Oceans, Volume 128, Issue 10, October 2023., 2023
Abstract Marine heatwaves (MHWs) and Cold Spells (marine cold spells (MCSs)) are events of extreme positive and negative temperature anomalies, that last 5 days or longer. These events have been diagnosed across oceans from sea surface temperatures (SSTs) and recognized to affect ecosystems' health worldwide.

A holistic and comprehensive data approach validates the distribution of the critically endangered flapper skate (Dipturus intermedius)

Journal of Fish Biology, Volume 103, Issue 3, Page 516-528, September 2023., 2023
Abstract Morphological similarities between skates of the genus Dipturus in the north‐eastern Atlantic and Mediterranean have resulted in longstanding confusion, misidentification and misreporting. Current evidence indicates that the common skate is best explained as two species, the flapper skate (Dipturus intermedius) and the common blue skate (D ...

Temperature change effects on marine fish range shifts: A meta‐analysis of ecological and methodological predictors

Global Change Biology, Volume 29, Issue 16, Page 4459-4479, August 2023., 2023
In this study we analyzed published articles reporting range shift responses to global warming in marine fish, totaling 595 depth and latitudinal responses. We identified differences in distribution shifts due to ecological variables such as niche affinity, rate of sea temperature change, and commercial exploitation, as well as methodological biases ...

Broodstock exposure to warming and elevated pCO2 impairs gamete quality and narrows the temperature window of fertilisation in Atlantic cod

Journal of Fish Biology, Volume 101, Issue 4, Page 822-833, October 2022., 2022
Abstract Impacts of global warming and CO2‐related ocean acidification (OA) on fish reproduction may include chronic effects on gametogenesis and gamete quality, as well as acute effects on external fertilisation. Here, temperature thresholds and OA‐sensitivity of gametogenesis and fertilisation were investigated in Atlantic cod, Gadus morhua.

Highly mixed impacts of near‐future climate change on stock productivity proxies in the North East Atlantic

Fish and Fisheries, Volume 23, Issue 3, Page 601-615, May 2022., 2022
Abstract Impacts of climate change on ocean productivity sustaining world fisheries are predominantly negative but vary greatly among regions. We assessed how 39 fisheries resources—ranging from data‐poor to data‐rich stocks—in the North East Atlantic are most likely affected under the intermediate climate emission scenario RCP4.5 towards 2050.

Deep demersal fish communities respond rapidly to warming in a frontal region between Arctic and Atlantic waters

Global Change Biology, Volume 28, Issue 9, Page 2979-2990, May 2022., 2022
Deep‐water species adapted to stable environments respond strongly to environmental change. In addition to a response to gradual warming, deep fish communities can be affected by climate events, detected at the surface, given the rapid behavioural nature of the responses observed in this study.

Multidisciplinary perspectives on living marine resources in the Arctic [PDF]

, 2022
Many areas in the Arctic are vulnerable to the impacts of climate change. We observe large-scale effects on physical, biological, economic and social parameters, including ice cover, species distributions, economic activity and regional governance ...
