Journal of Fish Diseases, EarlyView.ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic

Long‐term stability of transcrestal sinus augmentation
Periodontology 2000, EarlyView.Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

Preparation of Small Otoliths for Microscopic Examination
, 1987 We present a method for the preparation of small otoliths that consists of mounting otoliths in thin‐section epoxy on an acetate sheet. After mounting, the otoliths can be handled easily during grinding, polishing, and microscopic observation.

The taphonomic clock in fish otoliths
, 2021 Paleobiological and paleoecological interpretations rely on constraining the temporal resolution of the fossil record. The taphonomic clock, that is, a correlation between the alteration of skeletal material and its age, is an approach for quantifying ...
