But not, no matter if our very own efficiency suggest that variation in mastering abilities certainly one of bumble-bee territories represents the most likely factor getting seen variations in their foraging show, we are in need of further evidence to determine a beneficial causal link
Immediately after territories was in fact pulled on the job to measure foraging overall performance, these people were confronted by possible issues of parasites about pure ecosystem. Previous results as well as recommend that variation certainly territories in the inherent colour preference (to possess violet more than blue) make a difference to foraging performance (Raine & Chittka 2007a). Within our earlier studies, we looked at along with choice and you may foraging efficiency from colonies raised out-of crazy-trapped queens within natal habitat in which violet herbs put considerably more nectar than simply bluish flowers (Raine & Chittka 2007a).
