Japanese waters represent the northern distributional limit of the western Pacific distribution of the oceanic manta ray ( Mobula birostris) , yet movement ecology in this region remains poorly understood. We report movements of the first satellite‐tagged individual in Japan. High‐resolution depth–time series data documented repeated dives to 300 m and a maximum depth of 1082 m, with deeper use occurring predominantly at night...
Baleen Whale Occurrence in the Waters Off Virginia and North Carolina, U.S.A. From 2001 to 2019NARA Subscribed
Eighteen years of visual survey and strandings data were used to describe baleen whale occurrence along the continental shelf of Virginia and North Carolina, U.S.A. This region experiences heavy anthropogenic use, which poses risks for mortality and injury to baleen whales. Between 2001 and 2019, six species of baleen whales were recorded, and whales occurred year‐round. The total number of (on‐ and off‐effort) sightings and s...
Rates of maximal blood lactate accumulation in the extreme intensity exercise domain: implications for training prescriptionNARA Subscribed
Purpose This study investigated the rate of blood lactate accumulation ( v La) across six maximal sprint efforts and identified a breakpoint ( v La BP ) in the v La–power relationship. Methods Twelve physically active males completed 5, 10, 15, 20, 25, and 30-s all-out sprints in randomised order on separate days, with resistances set at 10 to 12.5% of body mass. The v La was calculated as the change in blood lactate between t...
