Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Chromium and Cobalt in Used Leather Items: A Danish Market Survey

Contact Dermatitis, Volume 95, Issue 3, Page 328-333, September 2026.
Used leather items from the Danish second‐hand market frequently release chromium(VI) and, in some cases, cobalt. Some items exceed current EU limits, highlighting a persistent but underrecognised source of exposure in the circular economy that may contribute to ongoing contact allergy despite existing regulations.

ezTrack: An R Package for Accessible Exploration of Animal Tracking Data

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This paper introduces an R package designed to make animal tracking data easier to clean, summarize, map, and visualize, especially for users who need practical workflows rather than highly specialized movement‐modeling tools. It provides functions for turning raw tracking data into a tidy format, generating summary statistics, plotting tracks and home
