Quick populace dynamics -The newest personal company out-of bees has actually a big affect the people biology and you will genetics (Pamilo and Crozier 1997, entire; Chapman and you will Bourke 2001, entire; Zayed 2009, entire). Brand new rusty patched bumble bee is actually an excellent eusocial bee kinds (cooperative brood care and attention, overlapping years contained in this a nest from grownups, and you may a division of labor towards reproductive and you will nonreproductive groups), and you can a society is made up of colonies unlike some one. Therefore, this new productive inhabitants size (number of individuals during the a society which contribute offspring towards the next generation) is much smaller than this new census people size (amount of people into the a people).
