We started the mark recapture project of florivores in Latnjajaure. Bombus lapponicus is so far the most common and truly beautiful but a species which previously was really rare at this elevation.

📢 Viewpoint in New Phyt. on polyploid establishment!
Key take-homes🧵
1. In contrast to earlier hypotheses that pollinators can help new polyploids establish, we suggest that pollinators mainly prevent polyploid establishment because outcrossing increases the strength of minority cytotype exclusion.

A special moment was spotting one of the rarest plants in Sweden ”Gentiana purpurea”. One single population in the country with 5-20 individuals flowering per year. Would be great to know more about the pollination of the species - at this time a single individual flowered
