Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Can a Low‐Threshold Check‐Up Motivate Older Adults to Schedule a Dental Visit? A Randomized Controlled Trial

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives Oral disorders are an important disability driver in adults aged 70 and older, who often experience greater tooth loss and higher levels of untreated oral disease than younger persons. Despite the importance of regular dental visits, older adults attend dental services less frequently, facing several barriers.

Kā pao te tōrea: Opportunities to Improve Oral Health Services for Māori

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objective Colonisation continues to shape Indigenous health outcomes today. Māori are the Indigenous people of Aotearoa New Zealand, and experience barriers to accessing care and a greater prevalence of dental caries, periodontal diseases, and tooth loss compared with non‐Māori.

Unravelling the phylogeny of armadillos and their kin (Mammalia, Xenarthra, Cingulata) combining morphological, molecular, and stratigraphic data

Cladistics, EarlyView.
Abstract Cingulata, a major lineage of Xenarthra, comprises extinct and extant armoured placental mammals that diversified throughout the Cenozoic. Despite extensive study, phylogenetic hypotheses based on morphological and molecular data remain incongruent, and no total evidence analysis has been conducted. Here, we integrate the largest morphological
