LifeMet: Report on the 2024–2025 meteorite recovery expedition in Dronning Maud Land, Antarctica for the study of microbe–meteorite interactions

Meteoritics &Planetary Science, EarlyView.
Abstract Since the discovery of nine meteorites near the Yamato mountains in 1969, Antarctica has been recognized as a superb location for meteorite recovery. While Antarctic recovery expeditions prioritize meteorite preservation for mineralogical and planetary studies, meteorites are not typically collected for biological applications.

Evolutionary legacies structure the geography of seagrass traits across the world's oceans

New Phytologist, EarlyView.
Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

Cretaceous moss–cyanobacteria association reveals trophic interactions in polar forests of Antarctica

New Phytologist, EarlyView.
Kimmerera cyanifera gen. et sp. nov. with associated cyanobacteria, holotype UWBM 116051. Summary Through symbiotic associations with microbes, mosses play many important ecological roles in terrestrial ecosystems, such as facilitating trophic interactions and nitrogen cycling.

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.
