..... the resolution and detail of the original quantitative surveys was astonishing - perhaps the oldest quadrat based seaweed survey? Not sure, but pretty neat all the same... General piece here... www.mba.ac.uk/historic-sea...

..... whereas populations in W Scotland seem to be more stable over decadal time scales. Both regions have warmed significantly but L. hyperborea closer to upper thermal limit (and trailing range edge) in SW England and summertime temps now stressful......

congrats! 👏

This experiment was logistically very challenging and required a huge team effort! Great to see the paper out and kudos to Owen Harris who led this as part of his MRes degree at MBA/Uni Plymouth

However, temps below the canopy were up to 14 deg C lower, as canopy fronds buffered subcanopy fronds from extreme stress and enhanced resilience of the population. Intraspecific facilitation likely to be very important during thermal stress.

We heated the air inside multiple tents on the low shore to simulate an extreme atmospheric heatwave with temperatures of up to ~47 deg C for multiple low tide periods. This was highly stressful (but not lethal) to canopy fronds.

As a NUFC fan of 30 years, i found the entire article to be perfect poetry. What a performance 🤌
