Intraspecific variation in body size of bumblebee workers influences anti-predator behavior

Sabrina Gavini, Carolina Quintero & Mariana Tadey
1.Flower dwelling predators make flowers dangerous foraging sites for pollinators, potentially affecting their anti-predator behavior. Moreover, predation vulnerability often varies among pollinators’ body-sizes with interspecific comparisons showing that smaller species are more vulnerable than larger ones. However, how intraspecific body size variation influences pollinator behavior under predation risk is still unknown, especially under natural conditions. 2.We hypothesized that bumblebee workers of different sizes will exhibit different foraging strategies under predation risk. We predict that (i)...
