Exploring the impacts of climate variability on the marine fishery ecosystems in the Southwest Atlantic Ocean is conducive to establishing an ecosystem‐based approach for the protection and rational utilization of fishery resources. In this study, long‐term fisheries data, 23 environmental data from the entire Southwest Atlantic, and 25 global climate data have been used to explore the regime shift of the fishery ecosystem and...

Variation in Antarctic sea ice strongly impacts marine ecosystem and fisheries. In this study, Antarctic sea ice extent (SIE) was used as an indicator to characterize the Antarctic sea ice variation, and its impact on habitat pattern of Argentine shortfin squid Illex argentinus , a climate-sensitive squid species extensively distributed in the Antarctic adjacent waters, was assessed using the habitat suitability index (HSI) mo...
