To further elucidate the drivers of animal migration, it is important to assess the interplay between resource tracking and memory across a wide range of species, in a diverse range of resource landscapes. The drivers of resource phenology vary across systems (e.g., marine versus terrestrial) and differ depending on the target resource. For example, in terrestrial systems, the emergence of highly nutritious plant growth can be influenced by static features, such as elevation (5), and less predictable weather events, such as rainfall (2). Likewise, the resource landscape of marine consumers is influenced by a suite of factors that shape primary production (e.g., winds, ocean currents, and mixing and stratification of the water column) (77) and prey distribution (e.g., intrinsic factors such as growth rates or physical features such as fronts and eddies that aggregate prey) (78). Despite these differences across systems, our study suggests that ecological theory of migration, and in particular the importance of resource tracking, is conserved across marine and terrestrial systems.
