trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...

Understanding how population dynamics change over time is critical to many practical problems as pest control, endangered species protection etc. Teaching population ecology is not easy since data is usually collected over a very long period. This paper discusses a specific tiger population case study relating to growth rate predictions using an online virtual lab. Studying tiger populations an...

With fewer than 200 tigers (Panthera tigris tigris) left in Nepal, that are generally confined to five protected areas across the Terai Arc Landscape, genetic studies are needed to provide crucial information on diversity and connectivity for devising an effective country-wide tiger conservation strategy. As part of the Nepal Tiger Genome Project, we studied landscape change, genetic variation,...

BACKGROUND Tiger populations are dwindling rapidly making it increasingly difficult to study their dispersal and mating behaviour in the wild, more so tiger being a secretive and solitary carnivore. METHODS We used non-invasively obtained genetic data to establish the presence of 28 tigers, 22 females and 6 males, within the core area of Pench tiger reserve, Madhya Pradesh. This data was eval...

Although the ecological consequences of species invasions are well studied, the ecological impacts of genetic introgression through hybridization are less understood. This is particularly true of the impacts of hybridization on "third party" community members not genetically involved in hybridization. We also know little about how direct interactions between hybrid and parental individuals infl...

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...
