Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, EarlyView.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Free Tools—Not So “Free”? The Evolution, Risks and Costs of Fishery Stock Assessment Tools

Fish and Fisheries, EarlyView.
ABSTRACT In fisheries stock assessment, free software tools have proliferated in recent years. These tools provide standardised and, in many cases, well‐tested and efficient ways to conduct and support stock assessments, making cutting edge expertise globally accessible.

Automating Ecological and Fisheries Modelling With Agentic AI

Fish and Fisheries, EarlyView.
ABSTRACT Fisheries modelling requires specialist training, but the availability of suitably skilled modellers is limiting delivery of science to inform management. Agentic AI can automate computing workflows and will increasingly be used in ecological modelling.

International Polar Year - 2012 - Antarctic Region

, 2012
Contained within the Atlas of Canada's Reference Map Series, 1961 to 2012, is a revised bilingual map which was produced as a special product for the International Polar Year 2012. It was produced from the British Antarctic Survey (2010) Antarctica and the Arctic 1:10 000 000 scale map, Series BAS (Misc) Sheets 15A and 15B. Its round shape shows detail

Zebrafish as a model for Catel–Manzke syndrome—identification and characterization of the zebrafish TGDS ortholog

The FEBS Journal, EarlyView.
Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.

High vulnerability of the endemic Southern Ocean snail Neobuccinum eatoni (Buccinidae) to critical projected oceanographic changes

Scientific Reports
Climate change is projected to substantially alter the Southern Ocean’s physical and chemical properties, thereby impacting its marine ecosystems and species, particularly those in Antarctic and sub-Antarctic regions.

Characterisation of a cold‐adapted, thermostable glucokinase from psychrophilic Pseudoalteromonas sp. AS‐131 reveals how the enzyme achieves high thermal stability without loss of cold adaptation

The FEBS Journal, EarlyView.
We investigated glucokinase from the psychrophilic Pseudoalteromonas sp. AS‐131 (PsGK), which was isolated from the Antarctic Ocean. Biochemical studies revealed that PsGK is a cold‐adapted enzyme with high thermal stability, in contrast to general cold‐adapted enzymes, which have low thermal stability.

Diverse baleen whale acoustic occurrence around two sub-Antarctic islands: A tale of residents and visitors

Scientific Reports
Knowledge on the occurrence and behaviour of baleen whales around sub-Antarctic regions is limited, and usually based on short, seasonal sighting research from shore or research vessels and whaling records, neither of which provide accurate and ...

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes

The FEBS Journal, EarlyView.
Cold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

Insect Conservation and Diversity, EarlyView.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for
