This chapter describes AtrapaelTigre.com, a citizen science project focusing on the Asian tiger mosquito in Spain. Commonly known for its aggressive biting during the day, the tiger mosquito represents a global environmental problem. It is an invasive species and a vector for dengue, chikungunya and other diseases, making it a serious public health risk. It is also an everyday nuisance and a th...

background: pantothenate kinase associated neurodegeneration (pkan) is the most prevalent type of neurodegeneration with brain iron accumulation (nbia) disorders characterized by extrapyramidal signs, and 'eye-of-the-tiger' on t2 brain magnetic resonance imaging (mri) characterized by hypointensity in globus pallidus and a hyperintensity in its core. all pkan patients have homozygous or compoun...
The tiger (Panthera tigris) is classified as endangered (IUCN, 2000). The population of wild tigers continues to decline, despite substantial conservation investments by governments and international agencies. This paper presents a formal economic analysis of the two most imminent threats to the survival of wild tigers: poaching of wild tigers and hunting their prey. A model is developed to exa...
Studies of spatial summation often use sinusoidal gratings with blurred edges. When the envelope is elongated (i) along the grating stripes and (ii) at right angles to the grating stripes, we refer to the stimuli as skunk-tails and tiger-tails respectively. Previous work [Polat & Tyler, 1999; Vision Research, 39, 887-895.] has found that sensitivity to skunk-tails is greater than for tiger-tail...
Many night-flying insects perform complex, aerobatic escape maneuvers when echolocating bats initiate attack. Tiger moths couple this kinematic defense with an acoustic reply to a bat's biosonar-guided assault. The jamming hypothesis for the function of these moth sounds assumes that tiger moth clicks presented at high densities, temporally locked to the terminal phase of the bat attack will pr...
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...
We present an algorithm which creates a German CCGbank by translating the syntax graphs in the German Tiger corpus into CCG derivation trees. The resulting corpus contains 46,628 derivations, covering 95% of all complete sentences in Tiger. Lexicons extracted from this corpus contain correct lexical entries for 94% of all known tokens in unseen text.
