OXPHOS genes analysis in the red mullet (Mullus barbatus Linnaeus, 1758)

Published: April 29, 2025

Red mullet, Mullus barbatus Linnaeus, 1758, is a very important target species of high commercial value for small-scale fisheries in the Mediterranean Sea. The distribution wide encompassing North-Eastern Atlantic (from Scandinavia to Senegal), Sea and Black Climatic differences across its range could trigger specific bioenergetic demands due that ectothermic aquatic exploit heat exchange with external environment regulate metabolic activities adaptation. Mitochondrial OXPHOS (mtOXPHOS) genes are particularly involved these processes they have been studied last decades as system subject selection under determined environmental constraints. Based on above considerations, purpose this work were analyze nucleotide sequences Cytochrome Oxidase I ( COI ) b Cytb seven populations M. , living within latitudinal between North Adriatic, Strait Sicily South, Ionian East Balearic Western Mediterranean. aims assess genetic diversity detect presence positive two-target protein-encoded using tests recombination based different models evolution. indices indicated higher values haplotype Adriatic than remaining both genes.

Spatiotemporal modelling of northern shrimp (Pandalus borealis) distribution patterns throughout Canada’s subarctic and arctic regions

Marine Ecology Progress Series, Journal Year: 2024, Volume and Issue: 740, P. 79 - 93

Published: July 8, 2024

Northern shrimp Pandalus borealis occur throughout Canada’s Atlantic Ocean, where they are thought to form a single population spanning from Baffin Bay the tail of Grand Bank. Here, play an important role in ecosystem as prey for many taxa and have been targeted by lucrative large-scale fishery since 1970s. Yet, we still understand little about which (and how) environmental factors influence their distribution abundance. We used survey data collected over 29 yr 23 degrees latitude develop spatiotemporal model predicting northern density. confirmed that both top-down drivers (e.g. predation pressure), well bottom-up bottom temperature) roles determining presence abundance shrimp. The was predict density entire study area 2005 2022. Our results highlight importance understanding dynamics relation patterns trends within resource assessments.

Comparative analysis of climate-induced habitat shift of economically significant species with diverse ecological preferences in the Northwest Pacific

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: Nov. 6, 2024

The Northwest Pacific Ocean is the most productive fishing ground in Ocean, with a continuous rise water temperature since 1990. We developed stacked species distribution models (SSDMs) to estimate impacts of climate change on dynamics economically significant under three scenarios for periods 2040-2060 and 2080-2100. Overall, important factor shaping patterns species, followed by depth. predictive results indicate that all show northward migration future, distance varies greatly among species. Most pelagic will expand their habitats change, implying stronger adaptability than benthic Tropical fishes are more adaptable other zones. Though limitations existed, our study provided baseline information designing climate-adaptive, dynamic fishery management strategy maintaining sustainable fisheries.

Coastal marine heatwaves in the Santa Barbara Channel: decadal trends and ecological implications

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: Dec. 16, 2024

Marine heatwaves (MHWs) are of increasing concern due to the emerging ecological and socioeconomic impacts on coastal ecosystems. Leveraging data Santa Barbara Coastal Long-Term Ecological Research project, we analyzed MHW event metrics observed in kelp forest ecosystem across Channel, CA, USA. Not only was there a significant positive trend number MHWs recorded, their duration intensity were also over time. detected year-round, suggesting that marine organisms have exposure risks regardless phenology. Exposure at one life history stage could legacy effect subsequent stages, implying little temporal refuge. In contrast, mooring revealed near-surface bottom events not necessarily coupled even less than 15 m. Such spatial variation might provide temporary refuge for mobile species. These observations highlight importance depth-stratified, long-term monitoring understand spatio-temporal stress communities.
