From diversity patterns to assembly processes: plankton community assembly along a natural salinity gradient in northern plateau lakes of China

This study reveals that increasing salinity along a natural gradient in northern Chinese plateau lakes drives a linear decline in plankton taxonomic diversity and functional richness, shifts community assembly from deterministic environmental filtering in freshwater to greater stochasticity in brackish waters, and partially decouples biodiversity from ecosystem functioning under salinity stress.

Spatiotemporal Assessment of Ambient Air Quality in Selected Urban, Tourist and Industrial Regions of Himachal Pradesh, India: A Case Study

This case study utilizes 30 days of public monitoring data from June to July 2026 to demonstrate that Himachal Pradesh's industrial and urban centers (Baddi and Solan) experience significantly higher air pollution levels driven primarily by particulate matter compared to tourist hill towns, establishing a critical baseline for differentiated air quality management across these distinct land-use settings.

Rainfall-Driven Variability of Physicochemical Water Quality Parameters in the Meghna River, Bangladesh: A Preliminary Monthly Assessment Using Correlation, Regression, and Principal Component Analysis

This preliminary study analyzes 2023 monthly data from the Meghna River in Bangladesh to explore rainfall-driven variability in physicochemical water quality parameters, revealing strong correlations between rainfall and specific pollutants like COD while explicitly acknowledging the statistical limitations imposed by a small sample size of six months.

Habitat contractions to drive future planktonic foraminifera distribution and diversity change

This study projects that global warming will drive planktonic foraminifera to shift poleward and experience significant abundance declines and diversity losses in low latitudes by 2100, with profound implications for oceanic carbon cycling and marine food webs.

Spatio-temporal Assessment of PM10 and its Correlation with Meteorological Parameters: A Case Study in Cumilla, Bangladesh

This study analyzes spatiotemporal variations of PM10 in Cumilla, Bangladesh, from January to April 2026, revealing peak concentrations in February that exceed national limits and a strong negative correlation with temperature and rainfall, thereby providing a basis for forecasting pollution peaks and designing seasonal mitigation policies.

El Nino Southern Oscillation-Driven Variability in Vegetation Indices and Carbon Fluxes over Rajasthan, India: A Non-parametric District-level Analysis (2000-2024)

This non-parametric district-level analysis of Rajasthan (2000–2024) reveals that El Niño events significantly suppress kharif vegetation and carbon fluxes, particularly in arid regions, while identifying strong positive long-term trends and enabling accurate 2026 forecasts based on ENSO and monsoon rainfall dynamics.

Analysis of Habitat Factors Influencing Natural Forest Regeneration Status of Tilaghor Eco-park in Bangladesh

This study evaluates the natural regeneration status of Tilaghor Eco-park in Bangladesh by analyzing 100 plots and applying NMDS and GLM models to determine that tree height, tree richness, and seedling metrics are the primary habitat factors significantly influencing seedling richness and abundance, thereby providing evidence-based guidelines for prioritizing indigenous species conservation and area-specific plantation strategies.

Benchmarking Machine Learning and Seismic-Derived Heat Flow Models to Decipher the Lithospheric Thermal Architecture of the Arabian-Nubian Shield

This study presents a novel benchmarking framework that combines a data-driven Random Forest model and a physics-based Velocity-Temperature conversion to map the thermal architecture of the Arabian-Nubian Shield, revealing that while both methods capture large-scale patterns, the machine learning approach offers superior predictive precision for geothermal resource assessment in complex tectonic settings.
