Kinematic comparison of bell contraction by four species of hydromedusae
Scientia Marina, 2000 Bell form strongly affects the hydrodynamic performance of swimming hydromedusae. Although the relationship between bell shape and hydrodynamic parameters has been documented for static models of different bell shapes, the dynamic differences in ...

Foraging dives of sperm whales in the north-western Mediterranean Sea [PDF]
, 2012 Oceanic odontocetes rely on echolocation to forage on pelagic or benthic prey, but their feeding ecology is difficult to study. We studied sperm whale foraging dives during summer in the north-western Mediterranean, using visual and passive acoustic ...

How information foraging styles relate to tourism demographics and behaviours [PDF]
, 2009 Scholars have investigated information search in tourism for decades and recently, the web’s role in information search. Rather than information search with a particular source, this study adds to the literature by focusing on information foraging across

Adaptive Lévy processes and area-restricted search in human foraging [PDF]
, 2013 A considerable amount of research has claimed that animals’ foraging behaviors display movement lengths with power-law distributed tails, characteristic of Lévy flights and Lévy walks.
