Latitudinal gradients in air density create invisible topography at sea level, affecting animal flight costs Air density affects the costs of animal flight. This is well-established for flight at high altitude. Shepard et al. show that changes in air density cause regional differences in flight costs at sea level due to latitudinal temperature gradients. They discuss the implications for species distributions and for global change. https://www.cell.com/current-biology/fulltext/S0960-9822(24)01459-3?dgcid=raven_jbs_etoc_email
