The doctoral program at Macquarie is a pathway to a career as a researcher in both academia and industry. In addition to managing their candidature and understanding their requirements as a researcher, doctoral students will complete a university-wide and a faculty-specific commencement program. They also have the opportunity to take advantage of a range of face-to-face courses and online training resources to leverage their degree to reach future career goals.

Project

In nature, potential evolutionary trade-offs exist between a species’ capacity to adapt to its pathogens versus its capacity to adapt to local environmental conditions. As pathogens attack, hosts can experience evolutionary changes that may be at the cost of environmental adaptation to novel or changing environments. Such interactions may be consequential in the context of a species' invasion success into new regions, as they may determine how invasions play out at landscape scales. The bumblebee, Bombus terrestris, though an economically important pollinator globally, is also an invasive insect in several countries. Bombus terrestris is native to the United Kingdom (UK), which is the source of the invasion in New Zealand (NZ), while NZ is the source of an invasion in the Australian island state of Tasmania. However, bumblebees remain absent from the Australian mainland. Notably, the economically devastating virus-transmitting Varroa mite of honeybees facilitates elevated transmission of highly pathogenic viruses, which can be transmitted to bumblebees via contact with honeybees during foraging. The Varroa mite is present in the UK and New Zealand, and although the east coast of the Australian mainland was recently invaded by Varroa in 2022, Tasmania remains Varroa-free.

This project is innovative in its linkages between population genetic connectivity and adaptive genetic variation with viral impacts. Distinctively, the project design enables examination of how pathogen selection pressures (i.e. from bee viruses and those related to Varroa) may trade off with environmental local adaptation in both native and invasive bumblebees. This project will use high resolution whole genome sequencing of bumblebees combined with climatic, landscape variables and data on local viral diversity, spanning the UK, New Zealand and Tasmania. Specifically, this PhD project will examine the following general questions:

  1. How do patterns of landscape genetic connectivity and adaptive variation differ in B. terrestris between its native (UK) and invasive (NZ and Tasmania) regions?
  2. How are viral taxonomic and phylogenetic diversity related to gene flow and local adaptation between sites, relative to the effects of landscape or climatic variables?
  3. Are there trade-offs between adapting to pathogen impacts (e.g. viral loads) and to local environments, what gene functions are involved, and does this depend on being an invasive or native bumblebee?

These questions will be addressed using cutting edge analytical approaches to detect selection across the genome at landscape scales. The results will shed light on the evolutionary processes that determine successful insect invasions. The study will also help to predict the spread of bumblebees to the Australian mainland or other global regions, and specifically, how viruses affect this process. By identifying selection trade-offs with viral infection and local adaptation in native and introduced B. terrestris, this study is also increases understanding about how diseases interact with hosts during biological invasions. This project will provide knowledge relevant for managing pollinators under disease threats and climate variability, and therefore the sustainability of food production and biodiversity function.

The project will be managed jointly between the School of Biology at St Andrews and the School of Natural Sciences at Macquarie. The student will be supervised by Prof. Oscar Gaggiotti (St Andrews) and by Dr Rachael Dudaniec (Macquarie).
