Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Harnessing Artificial Intelligence to Predict Dental Crowding in Modern Orthodontic Practice: A Comprehensive Review

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Dental crowding is fundamental to orthodontic diagnosis and treatment planning, yet what constitutes “crowding” remains surprisingly heterogeneous. Space analysis quantifies tooth size–arch length discrepancy, irregularity indices characterize alignment displacement, and clinician‐assigned severity reflects broader diagnostic interpretation ...

Body Size, Dental Pathology, and Maternal Genetic Diversity of Ancient Horses in the Eastern Baltic Sea Region and Western Russia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The early evolutionary history of modern domestic horses (Equus caballus/Equus ferus caballus), known as the DOM2 lineage, is well documented due to numerous archaeological and ancient DNA (aDNA) studies. Although many uncertainties remain in the domestication timeline, current evidence suggests that the domestication of modern horses began in

Dental Modifications Indicate Social Identity in the Insular Region of Wallacea, Indonesia 3634–2268 Cal BP

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The dispersal of Austronesian‐speaking people across Island Southeast Asia and the Pacific during the Late Holocene was associated with the spread of shared cultural practices, including intentional dental modifications. These practices, like tooth ablation and dental staining (likely with betel quid), are interpreted as embodied expressions ...

In Vitro Evaluation of Access Cavity Location Effect on Fracture Resistance of Maxillary Central Endodontically Treated Teeth

پزشکی بالینی ابن سینا, 2014
Introduction & Objective: Preparation of access cavity to root canal is a critical phase in endo-dontic treatment. The purpose of this study was to evaluate the effect of access cavity loca-tion (labial or palatal) on fracture resistance of ...

Simple plant–plant interaction patterns predict structural niche and fitness differences in a multitrophic grassland community

Oikos, EarlyView.
Understanding how species interactions relate to biodiversity requires linking complex interaction networks to coexistence mechanisms. In diverse communities, interactions span trophic levels and include pairwise and higher‐order effects, yet their relative importance for explaining population dynamics remains poorly understood.

Risk factors for dental overgrowth in rabbits: A retrospective study using electronic health records

Veterinary Record, EarlyView.
Abstract Background Rabbits’ teeth grow continuously. Overgrown teeth are a frequent cause for veterinary consultation and can have severe welfare implications. The risk factors for overgrown teeth are incompletely understood. Methods Rabbits with overgrown teeth recorded in their electronic health records (EHRs) were identified from a large population

Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

Wildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.

Localized resources enable noninvasive genetic monitoring of small populations of mountain ungulates

Wildlife Society Bulletin, EarlyView.
Using microsatellite analysis of fecal samples collected at mineral licks from 2019–2022, we assessed abundance, apparent survival and genetics of bighorn sheep in the Teton Range, Wyoming, USA. Annual abundance estimates ranged from 118−132 individuals split into 2 similar‐sized demes and apparent survival estimates ranged from 0.72–0.92.
