Using acoustic #telemetry to quantify #marine horizontal diel migration in very small cod 🐟 we show that:

• Migration timing closely tracks photoperiod
• During continuous daylight diel migration stops
• There is substantial among individual variation

Lodgepole pine in Iceland: biomass gains cannot be interpreted without ecological costs. Response to Riege et al. - New Forests We respond to Riege et al. (New For 56:68, 2025), who present valuable new data on early biomass accumulation by lodgepole pine (Pinus contorta) in Iceland. We argue that this finding cannot be evalua...

There’s plenty of lumpfish in the fjords, but we rarely catch them - our fishing is focused on the more mobile gadids.

Yesterday’s tiny (and very cute) by-catch was definitely worth a photo.

Revealing Chronotypes Across Aquatic Species Using Acoustic Telemetry Acoustic telemetry offers valuable opportunities to investigate individual variability in circadian-related and other behaviours and how environmental cues shape these patterns in wild fish populatio...

Chronotypes exist in at least 17 fish species. Our new study in Fish and Fisheries onlinelibrary.wiley.com/doi/10.1111/...

Love how curious these baby (young-of-year) Atlantic cod are😍

At the beggining of July, Theresa ( @theresahenke.bsky.social )set off for colder climates returning to the University of Iceland Research Centre of the Westfjords (& @fishiceland.bsky.social)‬ for a 6 weeks stay.

Stay tuned for updates on old & new projects :)

Takk fyrir! Sá greinina ykkar - og stefni á að lesa vel! Gaman að sjá meira um þessi grunnu fiskasamfélög! Við stefnum á að klára 1-3 greinar í viðbót um landnótar seiðin 🙂 - læt þig vita þegar það kemur út.

After so many years of toil, we've finally done it. Definitive proof that guppies can quantum phase shift between dimensions. Congrats to @helenanorman.bsky.social for this game-changing discovery. 🥳 #fishsci

Complementing Beach Seining With Dive Surveys Improves Fine‐Scale Resolution of 0‐Group Gadoid Distributions in Nearshore Habitats Located within the Westfjords of Iceland, the fine-scale depth distribution of juvenile 0-group gadoids was surveyed in nearshore nursery habitats using beach seine and dive survey methods. The beach....

🎣 New paper! Combining dive surveys and beach seining reveals contrasting nursery use: 0-group saithe dominate shallow algal zones early in summer, while cod settle later and use broader depths.

Population stratification in Northern shrimp (Pandalus borealis) off Iceland evident from RADseq analysis - BMC Ecology and Evolution The northern shrimp Pandalus borealis (ice. Stóri kampalampi) is a North Atlantic crustacean of significant commercial interest which has been harvested consistently in Icelandic waters since 1936. In...

Our paper describing the genetic stratification of inshore and offshore northern shrimp (Pandalus borealis) in Iceland just came out! RADseq data was collected from samples across Arnarfjörður bay in the North-West, Skjálfandi bay in the North.

Thousands gather across U.S. in Stand Up for Science events Scientists rally across the country in response to layoffs and funding cuts ordered by the Trump administration

Breaking news: Thousands of researchers and their supporters, including recently fired federal workers, have gathered across the U.S. in response to layoffs and funding cuts ordered by the Trump administration. scim.ag/41zlPv4

The CODSPA project funded by NordForsk is underway! Led by Marco Vindas, researchers from Norway, Iceland, and the Faroe Islands are joining to study how stress affects cod reproduction during spawning. The aim to ensure sustainable fishing practices and protect populations across the Nordic region.
