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.
2. đ§”Different processes that facilitate polyploid establishment on their own often co-vary negatively with each other, making associations difficult to find and causal frameworks essential. doi.org/10.1111/nph....

âGiven the similar #insect #biomass and #abundance between the two habitat types, #Natura 2000 areas do not seem to broadly benefit flower visitors more than #urban wastelands.â

The relationship between polyploid formation, triploid fitness and plant reproduction has been studied for over a century, and uniparental reproduction has long been recognized to play a crucial role...
đą Viewpoint in New Phyt. on polyploid establishment!
Key take-homesđ§”
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.
This must stop! We need a full arms embargo and sanctions now, so this killing with impunity ends.
Our new Canadian govt and PM need to speak up!

3. The increase in polyploid frequency with latitude could be explained by patterns in plant reproduction, especially the frequency of self-reproduction, rather than higher tolerance to abiotic stress as commonly suggested.
