Evidence suggests that non-domesticated felids inherited the same AB-erythrocyte antigens as domestic cats. To study the possible compatibility of tiger blood with that of other endangered felidae, blood samples from captive tigers and domestic cats were subjected to an in vitro study. The objectives of this study were to (1) identify whether the captive tigers had blood type AB and (2) determi...

The Caspian tiger (Panthera tigris virgata) flourished in Central Asian riverine forest systems in a range disjunct from that of other tigers, but was driven to extinction in 1970 prior to a modern molecular evaluation. For over a century naturalists puzzled over the taxonomic validity, placement, and biogeographic origin of this enigmatic animal. Using ancient-DNA (aDNA) methodology, we genera...

Little is known about the long-term movement patterns of most marine apex predators. A network of acoustic receivers was used to quantify the long-term movements of transmitterequipped tiger sharks Galeocerdo cuvier Péron & Lesueur, 1822 in the Main Hawaiian Islands. Tiger sharks were wide-ranging, swam between islands and patrolled up to 109 km of contiguous coastline. Visits to specific acous...

OBJECTIVE To determine the chemical compositions and evaluate the antimicrobial activity of bush tea (Athrixia phylicoides DC.), special tea (Monsonia burkeana) and synergy (combination of bush tea and special tea). METHODS Total polyphenols were determined using the methods reported by Singleton and Rossi (1965) and modified by Waterman and Mole (1994). Tannins were determined using vanillin...

Tigers, the largest of the felids, are now a globally threatened species with only approximately 3000 wild tigers surviving. India contains about 60% or 2000 of the animals, yet despite aggressive conservation efforts the number of tigers is declining. The causes of the decline are prey depletion, habitat destruction and poaching. Over the past 30 years of tiger conservation efforts in the vari...

Following the tragic events of 9/11, when al Qaeda terrorists crashed three airplanes into the World Trade Center and the Pentagon, Americans turned their frightened eyes toward George W. Bush to see just what kind of president he would be. Most people weren't sure what they would find. The new president was still hard to define. His campaign in 2000 had sent mixed signals on a variety of issue...

This paper documents the TIGER 700 RMRS Treebank which has been obtained as the result of a software project. The treebank is a semantic projection from a subset of the TIGER Dependency Bank and was derived automatically, using treebank conversion methods. In a second phase, it will be manually validated and corrections will be made as necessary, supported by an interactive editing tool.

Based on field studies, museums collections and literature sources, the current knowledge of the tiger beetle fauna of Israel and adjacent lands is presented. In Israel eight species occur, one of them with two subspecies, while in the Sinai Peninsula nine species of tiger beetles are now known. In the combined regions seven genera from two tribes were found. The Rift Valley with six cicindelid...

This paper shows new preimage attacks on reduced Tiger and SHA-2. Indesteege and Preneel presented a preimage attack on Tiger reduced to 13 rounds (out of 24) with a complexity of 2. Our new preimage attack finds a one-block preimage of Tiger reduced to 16 rounds with a complexity of 2. The proposed attack is based on meet-in-themiddle attacks. It seems difficult to find “independent words” of ...

Tiger moths (Erebidae: Arctiinae) have experienced intense selective pressure from echolocating, insectivorous bats for over 65 million years. One outcome has been the evolution of acoustic signals that advertise the presence of toxins sequestered from the moths' larval host plants, i.e. acoustic aposematism. Little is known about the effectiveness of tiger moth anti-bat sounds in their natural...
