Data from: There is no general model for occlusal kinematics in conodonts
2015
Knowledge of conodont element function is based largely on analysis of morphologically similar P1 elements of few comparatively closely related species known from abundant articulated remains. From these, a stereotypical pattern of rotational occlusion has been inferred, leading to the suggestion that this may represent a general model for ozarkodinin P1 elements at the very least. We test the generality of this occlusal model through functional analysis of Pseudofurnishius murcianus P1 elements which, though superficially similar to homologous elements in gnathodids, evolved their platform morphology independently, through a different mode of morphogenesis, and in a different topological p…
Data from: Transcriptomic data from panarthropods shed new light on the evolution of insulator binding proteins in insects
2017
Background Body plan development in multi-cellular organisms is largely determined by homeotic genes. Expression of homeotic genes, in turn, is partially regulated by insulator binding proteins (IBPs). While only a few enhancer blocking IBPs have been identified in vertebrates, the common fruit fly Drosophila melanogaster harbors at least twelve different enhancer blocking IBPs. We screened recently compiled insect transcriptomes from the 1KITE project and genomic and transcriptomic data from public databases, aiming to trace the origin of IBPs in insects and other arthropods. Results Our study shows that the last common ancestor of insects (Hexapoda) already possessed a substantial number …
Data from: The joint evolution of the Myxozoa and their alternate hosts: a cnidarian recipe for success and vast biodiversity
2018
The relationships between parasites and their hosts are intimate, dynamic and complex; the evolution of one is inevitably linked to the other. Despite multiple origins of parasitism in the Cnidaria, only parasites belonging to the Myxozoa are characterized by a complex life cycle, alternating between fish and invertebrate hosts, as well as by exceptionally high species diversity. This inspired us to examine the history of reciprocal interactions and adaptive radiations in myxozoans and their hosts by determining the degree of congruence between their phylogenies and by timing the emergence of myxozoan lineages in relation to their hosts. Recent genomic analyses suggested a common origin of …
Musical Self-Concept - Presentation of a Multi-Dimensional Model and Its Empirical Analyses
2009
Research on the specific domain of musical self-concept was so far exclusively concerned with musically active subjects (such as performers, music teachers, students, or singing children). In contrast, the starting base of the presented research is that music is a distinct aspect in everyone’s life and personality and that therefore musical self-concept is general and includes a number of domain besides achievement. The presented multi-dimensional model includes (i) non-academic and (ii) dimensions of musical ability. The first section entails representations with regards to “who I am” in music, such as emotional, social, physical, cognitive and spiritual notions, while section two addresse…
