(42) Comment: You to definitely commenter said the Service’s assertion the quick populace sized brand new rusty patched bumble-bee additionally the species’ breeding method make the types more susceptible so you can has an effect on from other products is wrong, for the reason that it reputation takes on the species’ inhabitants size and assortment has actually dramatically decreased.

One bumble bee fundamentally occupies a place less than step one rectangular kilometer, nevertheless the populations, being consisting of multiple private bees within the multiple colonies, span around the a much bigger diversity

Because the informed me on SSA, an excellent population include several practical colonies, which happen to be comprising hundreds of employee bumble bees. Its unfamiliar what specific short society dimensions manage end in a good diploid extinction vortex event, but given the studies, it is reasonable in conclusion your leftover populations is actually lower than green levels, and you can, if they have not even hit vortex levels, they are going to in the future when the declines commonly detained.
