Meteoritics &Planetary Science, Volume 61, Issue 5, Page 874-897, May 2026.Abstract Terrestrial weathering alters the chemical and isotopic composition, and mineralogy, of meteorites; its effects on ordinary chondrites are well‐studied, but relatively little is known about the susceptibility of carbonaceous chondrites. We combined laboratory experiments, whereby Chwichiya 002 (C3‐ung find), Murchison (CM2 fall) and Kolang ...

Assessing the role of foliar habit on nutrient losses in a sub‐Antarctic forest
Ecology, Volume 107, Issue 4, April 2026.Abstract Biogeochemical cycles drive global biodiversity and plant productivity. In terrestrial ecosystems, nutrient losses through plants' litter are a critical component of these biogeochemical cycles. In forests, nutrient losses are thought to be higher in deciduous angiosperm species than in evergreen conifers.
