Ecological risks Assessment of heavy metals from the Kidaro Creek, Niger Delta Nigeria

This study reveals that heavy metals, particularly cadmium, from anthropogenic petroleum activities have caused extremely high ecological risks and contamination in the surface water of Kidaro Creek, Niger Delta, while sediment contamination remains relatively low.

The need for improved models of zooplankton abundance

This study demonstrates that accounting for sampling bin-width-dependent heteroscedasticity using an inverse Gaussian generalized linear model significantly improves the robustness of zooplankton abundance predictions in the Southern Ocean compared to traditional log-transformed Gaussian models, thereby preventing biased ecological inferences.

Surface-to-subsurface inference via AlphaEarth: A shared foundation-model representation for diverse subsurface properties

This study demonstrates that the AlphaEarth foundation model's surface embeddings serve as a versatile shared geospatial representation for inferring diverse subsurface properties, acting either as augmenting features alongside traditional covariates or as primary descriptors depending on the target physics and prediction scale.

Quantitative Analysis of PlanktoScope Data: a powerful tool for exploring ecosystem function

This study demonstrates that the open-source PlanktoScope imaging system, combined with Ecotaxa, serves as a powerful, cost-effective tool for high-frequency monitoring of plankton community dynamics in La Paz Bay, successfully capturing seasonal shifts in composition and biomass that correlate with satellite-derived chlorophyll-a data.

Microenvironments Constrained Early Holocene Pastoralist Occupation in the Arid Eurasian Steppe

By combining machine learning land classification with archaeological survey data, this study demonstrates that Early Holocene pastoralist occupation in the arid Eurasian Steppe was not uniform but was instead structured by a reliance on rare, resource-rich microenvironments that served as thermal refugia and productive plant communities, particularly during summer months.

Process-based diagnosis of mid-Holocene temperature uncertainty in PMIP3 and PMIP4 simulations

This study utilizes a process-based climate feedback analysis to demonstrate that lower greenhouse gas concentrations in PMIP4 simulations suppress polar amplification by weakening key positive feedbacks, thereby resolving intergenerational discrepancies with proxy data and supporting a cooler mid-Holocene temperature relative to preindustrial times.
