Dear IUCN Colleagues,

Please find below the link to our paper "Global decline of bumblebees is phylogenetically structured and inversely related to species range size and pathogen incidence" that could be of interest.

Nice work Marina! Parasite results are really intriguing!

Thanks Mark!

It was surprising to find that the species where no internal parasites were reported were more vulnerable.

But then we realize, that if pathogens are virulent enough, we are mostly working with the survivors!

And those might be parasite-free.

But of course, and as usual, we have now more questions than answers.

Thanks again!

Marina

Or have not yet contracted those pathogens?

Yes, exactly, I meant survivors because they haven't get the pathogen... yet

Thanks for the clarification Paul!

Absolutely - variable interpretations, as you covered nicely in the paper. I'm looking forward to digging into your dataset to see where the parasites were and weren't!

Cheers

Marina, I also wonder if you could compare proportions of declining species per region?
This is because comparing the assessments of North, Meso and South America, there were great differences (25% of sp in decline for NA vs. 50% for MA). I wonder how this correlates with the other parameters you analyzed.
Best,
Rémy.
