A population-level framework for movement ecology. Measures of population-level geographic distributions and ranges and their quantified movement through time emerge from multiple processes including individual behaviors (sensu the movement ecology framework, [42]) and demographic processes, both of which occur within the context of external factors. Additionally, observation processes may influence observed population-level patterns and must be accounted for to obtain reliable inferences. Population-level movement can be estimated across a broad range of spatial and temporal scales beyond individual-level movement. Population-level and individual-level measures are each capable of capturing movement phenomena with some overlap between approaches such as patterns related to migration, vagrancy, and nomadism
