Evolutionary trends of the pharyngeal dentition in Cypriniformes (Actinopterygii: Ostariophysi). [PDF]
PLoS ONE, 2010 BACKGROUND: The fish order Cypriniformes is one of the most diverse ray-finned fish groups in the world with more than 3000 recognized species. Cypriniformes are characterized by a striking distribution of their dentition: namely the absence of oral ...

X-ray microtomography in biology [PDF]
Micron, 2012 Progress in high-resolution x-ray microtomography has provided us with a practical approach to determining three-dimensional (3D) structures of opaque samples at micrometer to submicrometer resolution. In this review, we give an introduction to hard x-ray microtomography and its application to the visualization of 3D structures of biological soft ...
