DNA analyses of wild pollinators provide a simple solution to reverse their declining populations

Bumblebees are among the most popular and widely recognised insect pollinators. Remarkably, we lack an understanding of some of the basic and fundamental aspects of bumblebee ecology and so our ability to manage the landscape to help reverse declines in the populations is limited.

A team led by scientists at the Centre for Ecology & Hydrology, working with researchers from the University of East Anglia, ZSL (Zoological Society of London), University of Bristol and the Centre for Biodiversity and Environment Research, UCL, combined genetic analyses with land scape ecology and modelling to  to reveal some of the previously hidden details of the ecology and genetic structure of queen and worker bumblebees, and their relationships with habitat variables, such as the availability of flowers. The genetics component of the work was led by Dr Seirian Sumner, in CBER, GEE.

By creating statistical models of the probability of year-on-year survival they demonstrated that survival of a bumblebee lineage from one year to the next was significantly related to the coverage of both spring and summer flower resources in the surroundings of the colony. These findings, published in Nature, suggest that agricultural landscapes must provide year-round resources if they are to be truly beneficial for their resident bumblebee populations.

These findings are applicable to anyone wishing to manage farmland, or indeed their own back gardens, in a bumblebee-friendly way. In particular, they offer effective management advice for conservation and show that conservation interventions that increase floral resources at a landscape scale and throughout the season have positive effects on wild pollinators in agricultural landscapes.

BBSRC grant success for Ziheng Yang's group to study Phylogeographic inference using genomic sequence data under the multispecies coalescent model

Publication date:

Prof Ziheng Yang

Ziheng has been awarded a three-year BBSRC grant (£399K) to work on "Phylogeographic inference using genomic sequence data under the multispecies coalescent model".  Dr Xiyun Jiao is hired as a postdoc on the grant.  Xiyun finished a PhD in statistics from Imperial, working on smart MCMC algorithms.  She will be joining Ziheng's group on 1 May 2017.

Also Dr Tomas Flouri will be joining Ziheng's group on the same day as a postdoc on another BBSRC grant.  Tomas has a PhD in theoretical computer science, and has been working on RAxML and PLL (phylogenetic likelihood library) in Professor Alexis Stamatakis's group.
