I am broadly interested in pollinator and pollination ecology, population genetics, movement ecology, and fire ecology. In my research, I attempt to combine elements of all of these areas.
Bumble Bee Movement
Knowing the scales at which organisms operate throughout their life is a critical component to ecological research and species conservation. After all, a valuable habitat that is wholly inaccessible to an individual, directly or indirectly, does not impact its fitness.
For bumble bees in particular, their movement patterns change with life stage, caste, behavioral phases, and response to landscape pattern. Research interest in their movement dates back at least to Darwin, but much is still to be learned. It is especially important to understand their movement ecology as mobile agents who pollination many of the world’s wild and crop plants.
The bumble bee life cycle consists of several distinct phases and opportunities for movement (Figure 1). Yet, for most components, little is known about when, why, and how far individuals move. For instance, we have some crude estimates of worker foraging distance for several species, but the scale of movement for queens and males is relatively unknown. Further, what we do know is often complicated by differences in methodology, study region, and even in how researchers use terminology (Figure 2).
