Velocity estimation in GPR data based on diffraction analysis: Methodology and application to Antarctic firn

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.
Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively

Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

SwarmGenomics: A Unified Pipeline for Individual‐Based Whole‐Genome Analyses

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Advances in sequencing technologies have made whole‐genome data widely accessible, enabling research in population genetics, evolutionary biology, and conservation. However, analysing whole‐genome sequencing (WGS) data remains challenging, often requiring multiple specialised tools and substantial bioinformatics expertise.

Investigation of Plant Growth Promotion Potential of Novel Compost‐Derived Bacilli and Anticipating Their In Vivo Effectiveness Through Mathematical Modelling

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Compost derived Bacillus isolates were screened for plant growth promoting traits, scored through modelling and validated in field trials on maize and okra. Selected strains enhanced growth significantly, enabling reduced chemical fertiliser use, ecofriendly bioinputs and improved soil health.
