Off Kaikoura, New Zealand, duskies are targeted for interactions by tourist vessels, swimmers and recreational vessels. To determine if human activity influenced dolphin behavior, I conducted shore-and vessel-based studies(More)
Predictive habitat models can provide critical information that is necessary in many conservation applications. Using Maximum Entropy modeling, we characterized habitat relationships and generated spatial predictions of spinner dolphin (Stenella longirostris) resting habitat in the main Hawaiian Islands. Spinner dolphins in Hawai'i exhibit predictable daily(More)
Between 2004 and 2006, large groups of melon-headed whales were recorded off the Big Island of Hawai'i. No other odontocete species were sighted in these groups.
