Effects of Organic and Inorganic Fertilizers on Biomass Production and Nickel Yield in the Hyperaccumulator Bornmuellera emarginata Under Field Conditions

Ecological Research, Volume 41, Issue 4, July 2026.
The aim of the present study was to evaluate the effect of fertilization regime (organic vs. inorganic) on the growth performance, nickel accumulation, and total nickel yield of the nickel hyperaccumulator Bornmuellera emarginata, cultivated under realistic field conditions in its native ultramafic environment in Northern Greece over a 3‐year period ...

Enhanced Nickel Uptake in Mixed Plant Communities of Hyperaccumulator and Non‐Hyperaccumulator Species Under Nickel Stress

Ecological Research, Volume 41, Issue 4, July 2026.
This study investigated how species richness and biotope space affect phytoextracted nickel mass. Growing monocultures and bicultures of two endemic species across a nickel stress gradient revealed that bicultures generally enhanced soil nickel bioavailability, aboveground biomass, and nickel phytoextraction compared to monocultures.

Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Ophiolite-Related Ultramafic Rocks (Serpentinites) in the Caribbean Region: A Review of their Occurrence, Composition, Origin, Emplacement and Ni-Laterite Soil Formation

Geologica Acta, 2006
Ultramafic rocks, mainly serpentinized peridotites of mantle origin, are mostly associated with the ophiolites of Mesozoic age that occur in belts along three of the margins of the Caribbean plate. The most extensive exposures are in Cuba. The ultramafic-
