Archeointensity Database and Geomagnetic Field Reference Curves for South America Over the Past 5 Millennia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...

Century‐long trends in plant diversity of temperate mountain vegetation are modulated along elevation gradient

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Resurvey studies in mountain forests of the Tatra Mountains (Central Europe) show that plant diversity has increased over the past century, particularly at lower elevations. These shifts were associated more with increased nitrogen deposition and reduced grazing pressure than with direct climate warming.

Using Natural History Collections to Determine the Relative Changes in Diversity and Distribution of Freshwater Molluscs in KwaZulu‐Natal, South Africa

open access: yesAfrican Journal of Ecology, Volume 64, Issue 2, March 2026.
ABSTRACT Research using natural history collections to track anthropogenic activities has recently been on the rise. Natural history collections have been utilised beyond their traditional taxonomic and systematic roles, generating data that shape present and future research.

Europe's Ecological Debt: Mapping Freshwater Restoration Needs

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
We used data from the Habitats Directive and the Water Framework Directive to assess freshwater‐related restoration needs across Europe using the Composite Indicator of Conservation Status. Freshwater restoration needs are widespread, with over 94% of River Restoration Units (R2U) showing unfavourable conservation status under at least one of the two ...

Long‐term population changes for the UK stag beetle Lucanus cervus—Evidence from citizen science surveys and museum collections

open access: yesInsect Conservation and Diversity, Volume 19, Issue 2, Page 318-330, March 2026.
The stag beetle Lucanus cervus is a European Protected Species and declining dead wood specialist, but long‐term population trends in the United Kingdom remain largely unknown. We used 82,883 citizen science records and historic data from museum records to compare geographic distribution trends, and results suggest a broadly stable distribution over ...

Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate ...

Self-calibration and direct georeferencing in terrestrial laser scanning

open access: yes, 2009
An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data.

Modelling the Climatic Suitability of Digitaria insularis, a Global Invasive Species, Under Climate Change Scenarios

open access: yesWeed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Grasses in the Poaceae family are major components of global ecosystems and agricultural systems, and their adaptive success has enabled some species to become highly competitive weeds. Digitaria insularis (sourgrass), a C4 perennial grass native to the Americas and now widely introduced elsewhere, has evolved herbicide resistance and poses an
