Hypolimnetic anoxia in oligotrophic lakes and its effects on nutrient supply and phytoplankton communities

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract Low concentrations of dissolved oxygen (DO) in hypolimnetic waters are becoming more common and could affect nutrient supplies available to phytoplankton communities in meso‐ and eutrophic lakes. We examined the connections among hypolimnetic DO, nutrient concentrations, and phytoplankton communities in 26 oligotrophic lakes in the Kawartha ...

Ambiguities in Assigning Single‐Crystal NMR Data to Individual Atoms in the Crystal Structure: A Case Study of Hambergite, Be2BO3OH, by 9Be and 11B NMR Spectroscopy, XRD Measurements and DFT Calculations

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 4, Page 400-415, April 2026.
The fundamental question of how to assign NMR resonances to specific atoms in the unit cell is addressed by using the 9Be and 11B spectra of the natural mineral hambergite as a model system. ABSTRACT The NMR interaction tensors of 9Be and 11B of hambergite, Be 2BO 3OH, were derived from single‐crystal NMR experiments.

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

open access: yesNear 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 ...

Species delimitation among Primula hirsuta and related taxa (Primulaceae) confirms the existence of cryptic species in the Europeans Alps

open access: yesTAXON, Volume 75, Issue 2, April 2026.
Abstract Primula sect. Auricula is the largest plant clade endemic to Western European mountains and hence an important model to study speciation in mountain plants. Within this section, a clade of closely related and largely cryptic taxa, with P. hirsuta and P. pedemontana as its most prominent members, has remained taxonomically challenging. New taxa
