Tiger beetles pursue prey by adjusting their heading according to a time-delayed proportional control law that minimizes the error angle (Haselsteiner et al 2014 J. R. Soc. Interface 11 20140216). This control law can be further interpreted in terms of mechanical actuation: to catch prey, tiger beetles exert a sideways force by biasing their tripod gait in proportion to the error angle measured...

Knowledge of the habitat use and migration patterns of large sharks is important for assessing the effectiveness of large predator Marine Protected Areas (MPAs), vulnerability to fisheries and environmental influences, and management of shark-human interactions. Here we compare movement, reef-fidelity, and ocean migration for tiger sharks, Galeocerdo cuvier, across the Coral Sea, with an emphas...

Tiger (Trinity Interpreter GEneratoR) is a new interpreter generator tool along the lines of vmgen, but with significant improvements in flexibility and feedback. Support for important new features such as instruction specialisation, replication and improved analysis of code at runtime are presented. A simple ‘C’ virtual machine imported into Tiger is used for demonstration purposes. Various re...

Tiger Shark is a scalable, parallel file system designed to support interactive multimedia applications, particularly large-scale ones such as interactive television (ITV). Tiger Shark runs under the IBM AIX® operating system, on machines ranging from RS/6000 desktop workstations to the SP2® parallel supercomputer. In addition to supporting continuous-time data, Tiger Shark provides scalabilit...

The survival of the tiger (Panthera tigris) is seriously threatened by poaching to provide raw materials for Traditional Chinese Medicines (TCMs). Most highly prized are the tiger's bones, which are used in combination with other animal and plant derivatives in pills and plasters for the treatment of rheumatism and other ailments. Hundreds of patent remedies have been produced which claim to co...

Occupying only 7% of their historical range and confined to forested habitats interspersed in a matrix of human dominated landscapes, tigers (Panthera tigris) typify the problems faced by most large carnivores worldwide. With heads of governments of tiger range countries pledging to reverse the extinction process and setting a goal of doubling wild tiger numbers by 2022, achieving this target w...

Effect of feeding on linseed oil (LO)-enriched Artemia was investigated on growth, survival and stress resistance of tiger barb (Puntius tetrazona) larvae. Larvae were fed by LO-enriched (2.5, 5 and 7.5 %) as well as non-enriched Artemia nauplii for 14 d, followed by 14 d feeding on non-enriched Artemia. Fish fed on enriched nauplii showed significant increase in growth performance at both 14th...
