We'd like to congratulate Prof Colin Adams who's been awarded this year's #BevertonMedal! 🏅 Colin was previously the FSBI's president and holds the chair in Freshwater Ecology @uofglasgow.bsky.social. His work includes evolutionary processes in the emergence of new fish diversity and fish migration.

New paper 🐟📈📉📏🌡️! Super happy to see this paper led by JM Matte out! We analyzed 50 years of juvenile Atlantic salmon data (Miramichi & Restigouche Rivers, Can) to test how size-at-age has changed and what’s driving it. bit.ly/4uSxlQ5 @thefsbi.bsky.social 🧵👇

The obsession with “star scientists” and “attracting top talent” fundamentally misunderstands research and higher education. Create a healthy environment that is attractive to all manner of scientists. Because that run of the mill, non-transformative, maybe slightly boring research matters, too.

Friday ice update - #Arctic sea ice extent is currently the 3rd lowest on record (JAXA data) • about 740,000 km² below the 2010s mean • about 1,500,000 km² below the 2000s mean • about 2,120,000 km² below the 1990s mean • about 2,400,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i...
Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between September and December by looking at the decadal average line positions.

When baby salmon emerge from the gravel, how far do they disperse to summer rearing grounds? We haven't known until now (at least at the population scale), because they're too small to tag. In a paper just out, we answered this question using parentage-based (genetic) tagging! tinyurl.com/39b2sfjd
