Geographic Variation and Core Signatures of the Root Canal Microbiome: A Cross‐Country Comparative Study

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim Root canal infections harbour complex microbial communities that may vary across geographic populations. This study aimed to compare the root canal microbiome across Spain, Sweden, and the USA, identifying key microbial taxa, compositional and functional differences, and cohort‐associated microbial signatures.

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

African ape carpal morphology is not too specialized to represent the ancestral hominin carpus

open access: yesJournal of Anatomy, EarlyView.
Knuckle walking is one hypothesized behavior of the Pan‐Homo last common ancestor. We analyzed carpal morphology, including Euclidean distances between behavioral pairs, to investigate whether the carpals of knuckle‐walking taxa appear relatively specialized.
