Short-term seed storage of two Mediterranean shrubs used in restoration: Simple...

Seed-based revegetation is fundamental in global restoration efforts. When seed storage is mandatory, knowledge of storage conditions that reduce ageing is essential for effective conservation of viable seeds. However, inappropriate storage is still frequent, particularly in local restoration projects involving native species. We investigated how different storage conditions (temperature and relative humidity) ...

Bottom-up cascading effects of quarry revegetation deplete bird-mediated seed d...

Quarrying activities cause profound modifications on ecosystems, such as removal of vegetation cover, biodiversity loss and depletion of ecosystem services. Ecological restoration stands as a solution to revert such effects. Concomitantly, awareness is currently being given on ecosystem services and ecological processes to evaluate restoration efficiency. The objective of the study was to assess restoration suc...

Adapting Agriculture to Climate Change: A Synopsis of Coordinated National Crop...

The Adapting Agriculture to Climate Change Project set out to improve the diversity, quantity, and accessibility of germplasm collections of crop wild relatives (CWR). Between 2013 and 2018, partners in 25 countries, heirs to the globetrotting legacy of Nikolai Vavilov, undertook seed collecting expeditions targeting CWR of 28 crops of global significance for agriculture. Here, we describe the implementation of...

Evolution of Flavylium-Based Color Systems in Plants: What Physical Chemistry C...

Anthocyanins are the basis of the color of angiosperms, 3-deoxyanthocyanins and sphagnorubin play the same role in mosses and ferns, and auronidins are responsible for the color in liverworts. In this study, the color system of cyanidin-3-O-glucoside (kuromanin) as a representative compound of simpler anthocyanins was fully characterized by stopped flow. This type of anthocyanin cannot confer significant color ...

Yellow Lake Pigments from Weld in Art: Investigating the Winsor & Newton 19th C...

Weld (Reseda luteola) was one of the main sources of yellow dyes used for dyeing textiles and to prepare artists’ pigments in Europe until the 19th century. For the first time, this work explores the technology of preparing weld lake pigments in the 19th century by Winsor & Newton (W&N), a renowned supplier of artists’ materials. Five recipes were discovered in the W&N 19th century Archive Database and reconstr...

Chemical characterization and bioactivity of phytochemicals from Iberian endemi...

Asteraceae family members are well-known for their medicinal potential, comprising several properties that make them unique among plants. Here we focus on Santolina semidentata, an endemic plant from the Iberian Peninsula, not yet described for its medicinal properties. Phytochemical characterization of S. semidentata was performed, concerning total phenol content, flavonoid content, antioxidant capacity, HPLC-...
