Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

PLANTS, PEOPLE, PLANET, EarlyView.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...

Digitisation as archival intermediary: Quantifying and qualifying Greta B. Stevenson's mycological collector networks

PLANTS, PEOPLE, PLANET, EarlyView.
Mass digitisation of natural science collections and archives has increasingly become a priority for scientific heritage institutions. Here, we explore the potential of mass digitisation to improve our understanding of the nature and history of scientific collaboration. Focusing on mycologist Greta B.

Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

Ashwagandha: Is It Safe? Part 1: A Regulatory Review

Phytotherapy Research, EarlyView.
ABSTRACT Over the last decade, ashwagandha (Withania somnifera (L.) Dunal, AS) has been brought under increasing scrutiny by EU regulators regarding its safety for the use in food supplements, culminating in a recent recommendation for an Article 8 procedure according to Regulation (EC) No. 1925/2006 in the European Union (EU).
