Diving deeper into the underlying white shark behaviors at Guadalupe Island, Mexico

Abstract Fine‐scale movement patterns are driven by both biotic (hunting, physiological needs) and abiotic (environmental conditions) factors. The energy balance governs all movement‐related strategic decisions. Marine environments can be better understood by considering the vertical component. From...
