Dr Grace Twiston-Davies

Postdoctoral Research Associate


I  am interested  in  the  ecology of  plants,  insects  and  landscapes and research that that can  inform  conservation,  policy  and  land  management. I  am  especially  passionate  about  research  that  aims to  make  the  most  of  our  landscapes  for  nature and for people. I  have previously studied  the  landscape-scale  wild  flower  meadow  restoration  at  the  Stonehenge  World  Heritage  Site  and  the  benefits  of  agri-environment  schemes  for  biodiversity.  I  am  a  member  of  Professor  Juliet  Osborne's  research  group  on  the  Biotechnology and Biological Sciences Research Council (BBSRC)  funded  project  studying  bumblebee  population  success  in  agricultural  landscapes.  Along  with  the  other  members  of  the  research  team,  I  am  investigating  bumblebee colony survival  in relation to  the landscape and available pollen and nectar sources using field  experiments  and  computer simulations.  The  aim  of  this  work  is  to  provide  robust  scientific  evidence  in  order  to  make  land  management  and  policy recommendations for healthy and sustainable agro-ecosystems.

My current Natural Environment Research Council (NERC) Knowledge Exchange project with Cornwall Area of Outstanding Natural Beauty (AONB) is working to support and develop the Cornwall AONB's new pollinator conservation initiative. We will extend the real-world impact of our bee behavior and population models to help inform landscape-scale management recommendations and to increase pollinators in the Cornish Landscape.

I am also a member of the Biosciences department in the College of Life and Environmental Sciences.
