🌱 Our work reveals Arctic seeds are warm-cued & drought-sensitive, a risky trait for the future.

Huge thanks to the organizers! 👏

🌿 Magnus Linn used a 100-year-old record to show a shift towards taller, slower-growing plants.
🏔️ Ditte Christiansen found micro-topography holds as much diversity as a 2km mountain slope!

5/5 Why it matters: With limited adaptation in gametophytes, wild plants' reproduction is vulnerable to heat waves, potentially disrupting ecosystems. Full study: onlinelibrary.wiley.com/doi/epdf/10....

4/5 Finding 3: Almost no acclimation capacity! Only pollen size under extreme heat showed adaptation (warmer populations made larger pollen). Other traits may depend on biochemical changes or shifted flowering times.

3/5 Finding 2: Heat hurts seeds. Both treatments reduced yield and quality. Warm-climate plants made fewer, smaller seeds - likely shifting resources to survival over reproduction.

2/5 Finding 1: Female gametophytes handle heat better than males. At 35°C/30°C:
✓ Ovaries grew larger with more ovules
✗ Pollen production dropped sharply
At 40°C/35°C: fewer but larger ovules, while all pollen traits declined.
