Magnesium isotope heterogeneity in oceanic island basaltsNARA Subscribed
Nutrient washing to amend nitrite accumulation during hydrocarbon remediation of Antarctic soilNARA Subscribed
Nitrogen-based fertilizers are frequently employed in bioremediation to stimulate microbial degradation of hydrocarbon contaminants. At Casey Station, in eastern Antarctica, a urea-based fertilizer was applied to seven engineered biopiles to remediate soils impacted by historic diesel spills. While this treatment enhanced hydrocarbon degradation, it also altered soil chemistry, resulting in elevated concentrations of ammonia a...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Marine sterols from brown seaweeds, particularly fucosterol and its oxidized derivative saringosterol, have shown therapeutic potential for Alzheimer’s disease (AD) and cardiovascular diseases. Here, we aimed to elucidate the cellular and in vivo mechanisms underlying their beneficial effects. In human HepG2 hepatocytes and CCF-STTG1 astrocytoma cells, we assessed liver x receptor (LXRα /LXRβ) activation, sterol uptake, and ef...

Combining Observations and Models: A Review of the CARDAMOM Framework for Data‐Constrained Terrestrial Ecosystem ModelingNARA Subscribed
The rapid increase in the volume and variety of terrestrial biosphere observations (i.e., remote sensing data and in situ measurements) offers a unique opportunity to derive ecological insights, refine process‐based models, and improve forecasting for decision support. However, despite their potential, ecological observations have primarily been used to benchmark process‐based models, as many past and current models lack the c...
Impact of Crop Type on Biodiversity GloballyNARA Subscribed
The negative impact of agricultural land on biodiversity is widely recognized. However, there remains a knowledge gap regarding the role of different crop types in maintaining biodiversity within the agricultural landscape. By extracting biodiversity data from global datasets and classifying different crop types, we quantified the contribution of different crop types to biodiversity. Our results indicate that biodiversity leve...
