Bumblebee (Bombus) species are ecologically and commercially important pollinators, but their species are in decline. And the declines of certain bumblebee species may be underestimated given that differentiation of bumblebee species in the wild can be difficult. This has been suggested because bumblebee species have relatively monotonous morphology, biogeographical variation in size and color patterns, as well as certain color patterns being repeated in two or more taxa. Three species of the Bombus sensu stricto, which share high levels of morphological similarity, we cannot differentiate them by morphology.
Recent genetic and chemical analyses have provided evidence for the confirmation of these three species but the degree to which they differ at the genetic level is currently limited. In addition, the level of genetic diversity each species holds is critical to understand how natural populations will respond to changing environmental conditions, as well as whether there is evidence of potential hybridization or introgression between the species of the Bombus sensu stricto. Lastly, the mechanisms by which coloration patterns are conserved across these species has not been previously explored.
My PhD project will use a combination of comparative and population genomic techniques for members of the Bombus sensu stricto to provide novel insights into species differentiation, population health, as well as the processes shaping their evolution.
