Dr Liz Humphreys
Position
Research Ecologist, BTO Scotland
Role
My current job is to develop research projects principally concerned with land management issues, with particular focus on woodland and urban/sub-urban habitats.
Qualifications
BSc (Hons) Environmental Biology, University of St Andrews, 1991-1995
MSc Ecology, University of Aberdeen, 1997-1998.
PhD Kittiwake Foraging and Energetics, University of Stirling, 1998-2002.
Research Interests/ Responsibilities
Previously to joining the BTO, my main research interests involved quantifying the factors that determine the foraging performance and energetics of seabirds.
More recently I have become interested in looking at factors which effect urban biodiversity. I am also interested in the impact of woodland management practices on bird populations.
Other Information
Honorary Lecturer, SBES, University of Stirling
Editor of the Seabird Group Newsletter and member of its Executive Committee.
