Jacob Davies
Research Ecologist
Jacob works as a Research Ecologist on the Wetland & Marine Team, carrying out data analysis for a wide range of projects.
Interests & Responsibilities
Since joining the BTO recently, Jacob has used terrestrial climate and oceanographic data to predict future seabird abundance in western Scotland, Northern Ireland and Ireland under climate change as part of the MarPAMM project. Jacob has broad research interests in ecology, particularly in demography and range dynamics and in the analysis of large spatial datasets. For his PhD research on the causes of Reed Warbler’s recent range expansion in Britain, he carried out colour-ringing and analysed CES, NRS, ringing and satellite data using hierarchical and individual-based models. Jacob’s original background in ornithology includes upland and woodland fieldwork in Scotland and the USA, mostly on raptors and passerines, and analysis of farmland wader declines. Jacob is also a keen nest recorder and holds a ‘C’ ringing permit.
