Sam Franks

Position

Research Ecologist

Role

I work on a range of projects examining the affect of climate change and habitat on bird populations, with a particular focus on migrants

Qualifications

2012 - PhD, Simon Fraser University, Canada: Population connectivity and the causes and consequences of differential migration in a long distance migratory shorebird, the Western Sandpiper
2005 - BSc Honours Zoology, University of Toronto, Canada

Research Interests/Responsibilities

My research interests focus on exploring how our changing environment is influencing avian populations, particularly long-distance migrants.  I'm particularly interested in investigating the ecological drivers of survival and productivity, and relating events across the annual cycle to changes in the demographic processes influencing population change.  Some of my research will also investigate how aspects of the environment, including habitat and climatic variables, influence patterns of avian distribution and abundance.  I've used a range of methods, including stable isotopes and geolocators, to track the movements and connectivity of migrant bird populations throughout the annual cycle and to investigate how events occurring in one season carry-over to influence fitness parameters in subsequent seasons.
