Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

Environmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

MANDIBULAR ALLOMETRY IN HYDROCHOERUS HYDROCHAERIS (LINNAEUS, 1766) (HYDROCHERINAE, CAVIIDAE)

Papéis Avulsos de Zoologia
The mammalian masticatory apparatus is a highly plastic region of the skull and thus subjected to singular ontogenetic trajectories. Here we present the first descriptive allometric pattern study of mandible among the capybara (Hydrochoerus hydrochaeris),

Bluetongue Virus Serotype 3 Follow‐Up of the 2024 Outbreak in Two Belgian Zoos

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
In summer 2024, Western Europe experienced extensive outbreaks of bluetongue virus Serotype 3 (BTV‐3), a Culicoides‐borne orbivirus. Clinical disease was first detected in August 2024 in one of two Belgian zoos, predominantly affecting European bison (Bison bonasus) and American bison (Bison bison).

Segmentation of cortical bone, trabecular bone, and medullary pores from micro‐CT images using 2D and 3D deep learning models

The Anatomical Record, Volume 308, Issue 12, Page 3082-3104, December 2025.
Abstract Computed tomography (CT) enables rapid imaging of large‐scale studies of bone, but those datasets typically require manual segmentation, which is time‐consuming and prone to error. Convolutional neural networks (CNNs) offer an automated solution, achieving superior performance on image data.
