Despite being targeted as a conservation flagship species for several decades, the tiger (Panthera tigris) grows ever more imperiled. Debate exists as to where tiger conservation should focus: on protected nature reserves or larger landscapes. We developed a landscape scale, density-based model to assess whether reasonably effective management of current reserves is adequate to ensure the survi...

Concentrations of polychlorinated biphenyls (PCBs), DDT and its metabolites (DDTs), HCH isomers (HCHs), chlordane compounds (CHLs) and hexachlorobenzene (HCB) were determined in sediment, soil, whole body homogenates of resident and migratory birds and their prey items (including fish, green mussel, snail, earthworm, crabs, prawn, lizard and frogs), bird eggs and bats collected from southern In...

Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of...

The Sundarbans tiger inhabits a unique mangrove habitat and are morphologically distinct from the recognized tiger subspecies in terms of skull morphometrics and body size. Thus, there is an urgent need to assess their ecological and genetic distinctiveness and determine if Sundarbans tigers should be defined and managed as separate conservation unit. We utilized nine microsatellites and 3 kb f...

A thin unhealthy Burmese boy named Moung Tsan, aged 15 years, was attacked by a tiger in the jungle, when returning from an adjacent hill accompanied by his father, oil the evening of the'Jth July 1881. The tiger caught him on the face and dragged him several yards, when his father, who had a dah in his hand, struck the animal on the head, on which the tiger left his prey and jumped on the fath...

This paper presents the annotation of the German TIGER Treebank. First, issues concerning the annotation, representation as well as querying of the treebank are discussed. Within this context, the annotation tool ANNOTATE, the export and XML formats of the TIGER Treebank and the TIGER search tool are briefly introduced. Secondly, the developments of the TIGER annotation scheme and their realiza...

Naïve red (Lasiurus borealis Müller) and big brown (Eptesicus fuscus Beauvois) bats quickly learn to avoid noxious sound-producing tiger moths. After this experience with a model tiger moth, bats generalize the meaning of these prey-generated sounds to a second tiger moth species producing a different call. Here we describe the three-dimensional kinematic and bioacoustic details of this behavio...

We describe a collision-finding attack on 16 rounds of the Tiger hash function requiring the time for about 2 compression function invocations. This extends to a collision-finding attack on 17 rounds of the Tiger hash function in time of about 2 compression function invocations. Another attack generates circular near-collisions, for 20 rounds of Tiger with work less than that of 2 compression f...

Tiger sharks (Galecerdo cuvier) are apex predators characterized by their broad diet, large size and rapid growth. Tiger shark maximum size is typically between 380 & 450 cm Total Length (TL), with a few individuals reaching 550 cm TL, but the maximum size of tiger sharks in Hawaii waters remains uncertain. A previous study suggested tiger sharks grow rather slowly in Hawaii compared to other r...
