The male Macrobrachium species (giant freshwater prawn) typically achieve better growth and a larger harvest size than females. Hence, it is clear that the monosex culture of all-male prawn populations would be inexpensively advantageous. This study aimed to determine whether androgenic gland (AG) ablation induces sex reversal giant dacqueti. AG was ablated through bilateral microsurgery (AG ab...

1. A predictive framework of community and ecosystem dynamics that applies across systems has remained elusive, in part because non-consumptive predator effects are often ignored. Further, it is unclear how much individual-level detail community models must include. 2. Previous studies of short-lived species suggest that state-dependent decisions add little to our understanding of community dyn...

The land that is now the state of Uttaranchal has a glorious history in tiger conservation; it was in the Corbett Tiger Reserve (TR)—one of the country’s most priceless reserves—that one of the most credited conservation programs of the century, Project Tiger, was launched in 1973 (1). While most tiger habitats in the country are experiencing severe anthropogenic pressures leading to degradatio...

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...

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...

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...

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...

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...
