A Unified Vector Electromagnetic Framework for Ionospheric Scintillation and Polarization Effects in GNSS

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Population trends and variability within bird communities are amplified by intense land use

Journal of Animal Ecology, Volume 95, Issue 6, Page 1047-1058, June 2026.
We show that bird populations in farmland have stronger long‐term changes and are more variable around these changes than in woodland. Disentangling these two components of population stability helps understand the effects of anthropogenic pressures on wild communities.

Rising Tides, Falling Harvests: Examining the Effects of Salinity Intrusion on Paddy Production in Vietnam's Mekong Delta

Journal of Agricultural Economics, Volume 77, Issue 2, Page 771-785, June 2026.
ABSTRACT Rising sea levels and salinity intrusion increasingly threaten rice farming in Vietnam's Mekong Delta. Using a district‐level panel dataset from 2000 to 2020, this study examines the impacts of salinity on Winter–Spring rice yields and acreage and how farmers adapt to salinity risk.

Ecological Processes Underpinning Microbial Variability in Archean Granitoids Beneath the Deccan Traps: Evidence From Deep Drilling in Koyna, India

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Deep biosphere hosted by Archean granitoid basement of Deccan Traps showed depth‐wise microbial partitioning. Limited dispersion and variable selection control community assembly. Fewer abundant bacterial taxa were ubiquitous, while large numbers of rare taxa remained localized.

Viral Assemblages of a Hypersaline Estuary Show Divergent Responses to Freshwater and Temperature Disturbances

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Metagenomic assessment of viromes at two sites in Laguna Madre, a hypersaline estuary, showed unique viral communities. Extreme cold temperature changes showed a greater propensity to enrich AMGs toward oxidative phosphorylation and sulfur metabolism. Extreme shifts in salinity led to homogenized viral taxonomic groups more similar to those typically ...

Bacterial Diversity and Functional Dynamics in the Soybean (Glycine max L.) Rhizosphere Under Different Organic Fertilisation

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Soybean (Glycine max L.) rhizosphere responses to organic fertilisation remain unknown. This study used 16S rRNA sequencing to assess microbial diversity under cattle dung and poultry manure. Results showed distinct community shifts, improved soil nutrients and stable core metabolic functions, highlighting organic inputs as sustainable strategies for ...
