      Harcourt, Rob; Martins Sequeira, Ana Micaela; Zhang, Xuelei; Rouquet, Fabien; Komatsu, Kosei; Heupel, Michelle; McMahon, Clive R.; Whoriskey, Frederick G.; Meekan, Mark; Carroll, Gemma; Brodie, Stephanie; Simpfendorfer, Colin; Hindell, Mark A.; Jonsen, Ian D.; Costa, Daniel P.; Block, Barbara A.; Muelbert, Monica M.; Woodward, Bill E.; Weises, Michael J.; Aarestrup, Kim; Biuw, Martin; Boehme, Lars; Bograd, Steven J.; Cazau, Dorian; Charrassin, Jean-Benoit; Cooke, Steven; Cowley, Paul D.; Nico De Bruyn, P.J.; Du Dot, Tiphaine Jeanniard; Duarte, Carlos M.; EguÍluz, Victor M.; Ferreira, Luciana; Fernández-Garcia, Juan; Goetz, Kim; Goto, Yusuke; Guinet, Christophe; Hammill, Mike; Hays, Graeme C.; Hazen, Elliot; Huckstadt, Luis; Huveneers, Charlie; Iverson, Sara; Jaaman, Saifullah A.; Kittiwattanawong, Kongkiat; Kovacs, Kit; Lydersen, Christian; Moltmann, Tim; Naruoka, Masaru; Phillips, Lachlan; Picard, Baptiste; Queiroz, Nuno; Reverdin, Gilles; Sato, Katsufumi; Sims, David W.; Thorstad, Eva B.; Thums, Michele; Treasure, Anne M.; Trites, Andrew; Williams, Guy D.; Yonehara, Yoshinari; Fedak, Mike A. (2019-06-26) - Journal item
      Animal telemetry is a powerful tool for observing marine animals and the physical environments that they inhabit, from coastal and continental shelf ecosystems to polar seas and open oceans. Satellite-linked biologgers and ...
    • Body density and diving gas volume of the northern bottlenose whale (Hyperoodon ampullatus) 

      Miller, Patrick; Narazaki, Tomoko; Isojunno, Saana; Suzuki, Kagari; Smout, Sophie Caroline; Sato, Katsufumi (2016-08-17) - Journal article
      Diving lung volume and tissue density, reflecting lipid store volume, are important physiological parameters that have only been estimated for a few breath-hold diving species. We fitted 12 northern bottlenose whales with ...
    • Body density of humpback whales (Megaptera novaengliae) in feeding aggregations estimated from hydrodynamic gliding performance 

      Narazaki, Tomoko; Isojunno, Saana; Nowacek, Douglas P.; Swift, Rene; Friedlaender, Ari S.; Ramp, Christian; Smout, Sophie; Aoki, Kagari; Deecke, Volker B.; Sato, Katsufumi; Miller, Patrick J. O. (2018-07-12) - Journal article
      Many baleen whales undertake annual fasting and feeding cycles, resulting in substantial changes in their body condition, an important factor affecting fitness. As a measure of lipid-store body condition, tissue density ...
    • Development of an animal-borne blood sample collection device and its deployment for the determination of cardiovascular and stress hormones in phocid seals 

      Takei, Yoshio; Suzuki, Ippei; Wong, Marty K. S.; Milne, Ryan; Moss, Simon; Sato, Katsufumi; Hall, Ailsa (2016-10-06) - Journal article
      An animal-borne blood sampler with data-logging functions was developed for phocid seals, which collected two blood samples for the comparison of endocrino-logical/biochemical parameters under two different conditions. The ...
    • High diving metabolic rate indicated by high-speed transit to depth in negatively buoyant long-finned pilot whales 

      Aoki, Kagari; Sato, Katsufumi; Isojunno, Saana; Narazaki, Tomoko; Miller, Patrick J.O. (2017-10-18) - Journal article
      To maximize foraging duration at depth, diving mammals are expected to use the lowest cost optimal speed during descent and ascent transit and to minimize the cost of transport by achieving neutral buoyancy. Here, we ...
    • Neutral buoyancy is optimal to minimize the cost of transport in horizontally swimming seals 

      Sato, Katsufumi; Aoki, Kagari; Watanabe, Yuuki Y.; Miller, Patrick J. O. (2013-07-16) - Journal article
      Flying and terrestrial animals should spend energy to move while supporting their weight against gravity. On the other hand, supported by buoyancy, aquatic animals can minimize the energy cost for supporting their body ...
