Samuel Haché

AMREMy main research interests are in avian ecology, population dynamics, and conservation biology.  Since 2006, I have been working to understand the effects of partial harvesting on population dynamics of forest songbirds in New Brunswick.  Most of my work consisted in quantifying the demographic response of Ovenbird.  I did my MSc at the Université de Moncton (supervisor: Dr. Marc-André Villard) and PhD at the University of Alberta (supervisor: Dr. Erin Bayne).  I also used multiple markers (e.g. stable isotope ratios, geolocators, genetic analyses, etc.) to track bird movements and understand the phylogeography of migratory songbirds.  As a postdoctoral fellow, I am working as project ecologist for the Boreal Avian Modelling project.  The main project that I worked on had for objective to identify the critical habitat for Canada Warbler, Olive-sided Flycatcher, and Common Nighthawk across Canada.
