ENHYDROSS: A New Mechanistic Model Supports the Trans-Oceanic Dispersal Capability of Terrestrial Vertebrates. [PDF]

open access: yesEcol Evol
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;
