Michael Hallworth is an ecologist who takes a full annual cycle approach toward understanding the interplay between the environment and population demography. To do this, he integrates movement across multiple spatial scale—from fine scale habitat selection of individuals to intercontinental migrations of populations. Hallworth has three overarching goals: to reveal the mechanisms that drive behavior, life-history and demographics of wildlife populations; to identify where migratory individuals and populations are throughout the year to better inform conservation; and to determine when and where wildlife populations are limited.
