Spectral Parameter Power Series Representation for Regular Solutions of the Radial Dirac System

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 2098-2113, February 2026.
ABSTRACT A spectral parameter power series (SPPS) representation for the regular solution of the radial Dirac system with complex coefficients is obtained, as well as a SPPS representation for the (entire) characteristic function of the corresponding spectral problem on a finite interval. Based on the SPPS representation, a numerical method for solving

When species are lost but functions persist: a trait‐based perspective on Wadden Sea bird diversity dynamics

Oikos, Volume 2026, Issue 2, February 2026.
Biodiversity faces several global threats and communities are likely to show complex delayed responses. Accurately measuring these lags is critical to properly understand diversity dynamics. Here, we investigated these delays with minimal data availability and found critical mismatches between the temporal dynamics of taxonomic and functional diversity

A Generalized Data‐Driven Shoreline Model at the Regional Scale

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Shoreline models underpin long‐term coastal planning and hazard mitigation but are often limited by site‐specific calibration and simplified process representations. While machine learning (ML) approaches have recently matched or exceeded the skill of traditional models in deterministic shoreline forecasting, they have yet to demonstrate ...

Multispectral Data and LiDAR for Enhanced Georeferencing of Gdanska Glowa's 17th‐Century Fortifications

Archaeometry, Volume 68, Issue 1, Page 94-106, February 2026.
ABSTRACT This study presents a novel remote sensing method to detect 17th‐century environmental elements associated with the historical fortifications of Gdanska Glowa in Poland. By integrating 10‐band multispectral imaging, high‐resolution (1 m) digital elevation models, vegetation metrics and random forest classification within Google Earth Engine ...

Generalized product formulas for Whittaker's functions and a novel class of index transforms

Generalized product formulas and index transforms, involving products of Whittaker's functions of different indices are established and investigated. The corresponding inversion formulas are found. Particular cases cover index transforms with products of the modified Bessel and Whittaker's functions.

Mapping Mediterranean bentho‐demersal communities to better inform marine conservation

Conservation Science and Practice, Volume 8, Issue 2, February 2026.
Marine protected areas are one of the most common conservation tools being implemented worldwide to reach conservation targets, but their implementation does not usually take the heterogeneous distribution of bentho‐demersal communities into account.

Achieving Full Representativity of Seafloor Biodiversity With Minimal Expansion: Exploring a Strategy for New Zealand Marine Conservation

Diversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim A key element of the Global Biodiversity Framework Target 3 is ‘representativity’, which refers to the inclusion of the full range of existing ecosystems, ecological processes and regions within protected areas, with the aim of ensuring that the full spectrum of biodiversity is protected.

Environmental Filtering Correlates More Strongly With Taxonomic and Functional Beta Diversity of Phytoplankton Assemblages Than Spatial Structuring in a High‐Altitude River–Lake System

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Understanding overall beta diversity (βtotal) and its components—species replacement (βrepl) and richness difference (βrich)—is essential for disentangling the mechanisms that structure aquatic communities. However, it remains poorly understood how taxonomic and functional beta diversity correlate with environmental and spatial processes in ...
