  abstract  = {Xenopus laevis (XLA) is an allotetraploid species which appears to have undergone whole-genome duplication after the interspecific hybridization of 2 diploid species closely related to Silurana/Xenopus tropicalis (XTR). Previous cDNA fluorescence in situ hybridization (FISH) experiments have identified 9 sets of homoeologous chromosomes in X. laevis, in which 8 sets correspond to chromosomes 1-8 of X. tropicalis (XTR1-XTR8), and the last set corresponds to a fusion of XTR9 and XTR10. In addition, recent X. laevis genome sequencing and BAC-FISH experiments support this physiological relationship and show no gross chromosome translocation in the X. laevis karyotype. Therefore, for the benefit of both comparative cytogenetics and genome research, we here propose a new chromosome nomenclature for X. laevis based on the phylogenetic relationship and chromosome length, i.e. XLA1L, XLA1S, XLA2L, XLA2S, and so on, in which the numbering of XLA chromosomes corresponds to that in X. tropicalis and the postfixes 'L' and 'S' stand for 'long' and 'short' chromosomes in the homoeologous pairs, which can be distinguished cytologically by their relative size. The last chromosome set is named XLA9L and XLA9S, in which XLA9 corresponds to both XTR9 and XTR10, and hence, to emphasize the phylogenetic relationship to X. tropicalis, XLA9_10L and XLA9_10S are also used as synonyms.},

  abstract  = {The invertebrate trace fossils from the Keuper (Upper Triassic) of the southern part of the Germanic Basin are revised. The Keuper sediments of the Germanic Basin are predominantly composed of rocks representing various nonmarine environments dominated by red-bed facies. The W{\"u}rzburg Formation, the Stuttgart Formation, and the Hassberge Formation, all representing deposits of extended river systems, contain the richest ichnofauna. Trace fossil abundance is generally low and their occurrence is scattered. The studied material can be assigned to 28 ichnogenera, 38 ichnospecies, and 6 vernacular forms. Among the described trace fossils are one new ichnogenus and three new ichnospecies. Apart from the revision of the invertebrate trace fossils from the Keuper numerous related ichnotaxa from various localities and ages have been studied and revised. In the course of these studies several ichnotaxa are synonymised, lowered in rank, and new ichnogenera, subichnogenera, and ichnospecies are suggested. In addition, general guidelines for naming, and methodologies for studying invertebrate trace fossils are presented. The palaeoecology of three ichnocoenoses, one from the W{\"u}rzburg Formation and two from the Hassberge Formation in Lower Franconia are briefly discussed.},
