Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Methods in Ecology and Evolution, EarlyView.Abstract Macroevolutionary adaptation of a continuous trait to different discrete states across species can be modelled using a phylogenetic state‐dependent Ornstein–Uhlenbeck (OU) process. Existing inference methods face two challenges. First, although efficient likelihood algorithms for continuous trait evolution models exist, none have been ...

Australian Endodontic Journal, EarlyView.ABSTRACT Achieving profound local anaesthesia during mandibular molar root canal treatment can be challenging. This study evaluated procedural pain and supplemental anaesthesia used, considering endodontic diagnosis and buccal bone morphology. Seventy‐seven patients undergoing primary root canal treatment completed a post‐treatment survey questionnaire

Australian Endodontic Journal, EarlyView.ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and
