Journal ArticleDOI
The songbird syrinx morphome: a three-dimensional, high-resolution, interactive morphological map of the zebra finch vocal organ
Daniel Normen Düring,Alexander Ziegler,Christopher K. Thompson,Christopher K. Thompson,Andreas Ziegler,Cornelius Faber,Johannes Müller,Constance Scharff,Coen P. H. Elemans +8 more
TL;DR: The results show that the syringeal skeleton is optimized for low weight driven by physiological constraints on song production, and a cartilaginous structure suited to play a crucial role in the uncoupling of sound frequency and amplitude control, which permits a novel explanation of the evolutionary success of songbirds.
Journal ArticleDOI
Future challenges in cephalopod research
José C. Xavier,A. Louise Allcock,Yves Cherel,Marek R. Lipinski,Graham J. Pierce,Paul G. Rodhouse,Rui Rosa,Elizabeth K. Shea,Jan M. Strugnell,Erica A. G. Vidal,Roger Villanueva,Alexander Ziegler +11 more
TL;DR: The present paper presents brief reviews on these topics, followed by a discussion of the general challenges that cephalopod research is bound to face in the near future.
Journal ArticleDOI
Aetiology, incidence and morphology of the C-shaped root canal system and its impact on clinical endodontics.
TL;DR: A systematic search was conducted using the MEDLINE, BIOSIS, Cochrane Library, EMBASE, Google Scholar, Web of Science, PLoS and BioMed Central databases, and many rarely cited articles were included to summarize current knowledge regarding C-shaped roots and root canals.
Journal ArticleDOI
Application of magnetic resonance imaging in zoology
Alexander Ziegler,Martin Kunth,Susanne Mueller,Christian Bock,Rolf Pohmann,Leif Schröder,Cornelius Faber,Gonzalo Giribet +7 more
TL;DR: The principles underlying various applications of this technique such as the use of contrast agents, in vivo MRI, functional MRI, as well as magnetic resonance spectroscopy are outlined to initiate further uses of MRI in zoology.
Journal ArticleDOI
Systematic comparison and reconstruction of sea urchin (Echinoidea) internal anatomy: a novel approach using magnetic resonance imaging
TL;DR: This investigation explores the possibility to systematically visualize the internal anatomy of echinoids obtained from various museum collections and shows that magnetic resonance imaging can give rapid, destruction-free access to morphological data from numerous specimens, thus extending the range of techniques available for comparative studies of invertebrate morphology.
