Many pollinator species, recognised as essential for ecosystem function, are undergoing rapid declines. One recent exception is the ‘Tree Bumblebee’ Bombus hyponorum: expanding its range into and across the UK in <20 years, it is now one of our most common species.
Building on previous work from the supervisory team, and in collaboration with the Earlham Institute, this project will investigate key genomic differences between this and other bumblebee (Bombus) species to substantially improve our understanding of the factors contributing to its success, along with the declines of others. While focused on one taxonomic group, the project has much broader relevance in understanding organismal responses to environmental change.
The project’s focus is a genomic comparison of Bombus species from within the UK and continental Europe. Initial work has identified genomic regions of interest in B. hypnorum that may be indicative of an enhanced ability to adapt to anthropogenically altered landscapes. However, current data are preliminary and lack essential phylogenetic comparison.
This is an exciting opportunity to generate a substantial and highly novel genomic dataset to test hypotheses as to whether the observed genomic differences are unique to B. hypnorum, or shared among Bombus species (some evidence suggests elevated resilience in the wider Pyrobombus sub-genus). In addition to fulfilling the specific aims, the data generated will offer the candidate significant scope to guide the project’s further direction through characterisation of genomic signatures and differences across this important group.
