Most examples of intercontinental dispersal events after the Miocene contact between Africa and Asia involve mammal lineages. Among amphibians, a number of probably related groups are known from both continents, but their phylogenies are so far largely unresolved. To test the hypothesis of Miocene dispersal against a Mesozoic vicariance scenario in the(More)
We describe a new species of the agamid genus Calotes Cuvier, 1817 from southern Vietnam, which is most similar to Calotes mystaceus Duméril & Bibron, 1837, but can be distinguished from the latter and its other congeners by genetic and morphological differences. We discuss the current distribution of the new species and its sister species C. mystaceus in(More)
Madagascar and the Seychelles are Gondwanan remnants currently isolated in the Indian Ocean. In the Late Cretaceous, these islands were joined with India to form the Indigascar landmass, which itself then split into its three component parts around the start of the Tertiary. This history is reflected in the biota of the Seychelles, which appears to contain(More)
We used molecular techniques to examine 11 species of frogs in 6 localities in southern Chile to ascertain the incidence of the chytrid fungus Batrachochytrium dendrobatidis (Bd). We detected the fungus in 2 localities (Coñaripe and Raúl Marín Balmaceda) in 3 species: Batrachyla leptopus, Pleurodema thaul and Rhinoderma darwinii. Our findings expand the(More)
Individual synthetic material tracheal canulae for laryngectomized patients. The usual standard tracheal canulae leads in laryngectomized patients because of too strong curvature to lesions of the front side not rarely, which cause tracheal stenoses. Therefore individual short synthetic material tracheal canulae are recommended. The have stood the test(More)

Africa is renowned for its biodiversity and endemicity, yet little is known about the factors shaping them across the continent. African Agama lizards (45 species) have a pan-continental distribution, making them an ideal model for investigating biogeography. Many species have evolved conspicuous sexually dimorphic traits, including extravagant breeding(More)
While traditionally species recognition has been based solely on morphological differences either typological or quantitative, several newly developed methods can be used for a more objective and integrative approach on species delimitation. This may be especially relevant when dealing with cryptic species or species complexes, where high overall(More)
The sandfish (Scincus scincus) is a lizard having the remarkable ability to move through desert sand for significant distances. It is well adapted to living in loose sand by virtue of a combination of morphological and behavioural specializations. We investigated the bodyform of the sandfish using 3D-laserscanning and explored its locomotion in loose desert(More)
