Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1042-1056, July 2026.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

The promise of digital herbarium specimens in large‐scale phenology research

New Phytologist, Volume 251, Issue 2, Page 617-624, July 2026.
Summary The online mobilization of herbaria has made tens of millions of specimens digitally available, revolutionizing investigations of phenology and plant responses to climate change. We identify two main themes associated with this growing body of research and highlight a selection of recent publications exemplifying: investigating phenology at ...

Longevidade pós-colheita de alpínia [Alpinia purpurata (Vieill.) K. Schum.] tratada com soluções de sacarose e extratos aquosos naturais Postharvest longevity of red ginger [Alpinia purpurata (Vieill.) K. Schum.] treated with sucrose solutions and natural water extracts

Revista Brasileira de Plantas Medicinais, 2010
A alpínia (Alpinia purpurata) é uma planta tropical encontrada em diversas regiões do Brasil com excelente potencial para a comercialização como flor de corte. Entretanto, a senescência das hastes pela exaustão da sacarose é um dos principais fatores que

Bridging data silos to holistically model plant macrophenology

New Phytologist, Volume 251, Issue 2, Page 625-636, July 2026.
Summary Phenological response to global climate change can impact ecosystem functions. There are various data sources from which spatiotemporal and taxonomic phenological data may be obtained: mobilized herbaria, community science initiatives, observatory networks, and remote sensing.

Using reflectance spectra and Pl@ntNet to identify herbarium specimens: a case study with Lithocarpus

New Phytologist, Volume 251, Issue 2, Page 800-810, July 2026.
Summary The digitisation of plant collections is bringing large quantities of information into accessible electronic databases. However, in recent decades, traditional taxonomic work in collections has declined, meaning that more specimens are only determined to family or genus, particularly when lacking key identification structures.

Linking Probabilistic Forecast Reliability to the Mismatch Between Model–Observation and Model–Model Correlations in Dynamical Seasonal Prediction

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract Reliability is central to probabilistic forecast skill, and linking it to nonprobabilistic diagnostics is essential for interpreting its behavior and deficits. Although recent studies have suggested a possible relationship between reliability in dynamical seasonal prediction and the mismatch between model–observation correlation (r $r$) and ...
