Odontocete spatial patterns and temporal drivers of detection at sites in the Hawaiian islands
Successful conservation and management of marine top predators rely on detailed documentation of spatiotemporal behavior. For cetacean species, this information is key to defining stocks, habitat use, and mitigating harmful interactions. Research focused on this goal is employing methodologies such...

We demonstrate the variability of temporal patterns even at relatively close sites, which may imply that wide-ranging models of species presence are missing key fine-scale movement patterns.

Successful conservation and management of marine top predators rely on detailed documentation of spatiotemporal behavior.
