The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

The Flowering Unit in the Synflorescences of Amaranthaceae

open access: yesThe Botanical Review, 2009
The structure of the synflorescence and the flowering units in Amaranthaceae are characterized. The synflorescence is polytelic. In the flowering unit we recognize the main florescence and the enrichment zone. The florescences may consist of: (1) Fully developed partial florescences bearing three or more flowers; (2) Partial florescences reduced to one

Evolutionary framework and tribal circumscription of Amaranthaceae sensu stricto based on a comprehensive phylogenomic analysis

open access: yesCladistics, EarlyView.
Abstract The evolutionary history of Amaranthaceae sensu stricto (s.s.) has been shaped by multiple whole‐genome duplications and rapid radiations, producing an ecologically diverse lineage whose internal relationships have long remained unresolved.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Anthocyanins and betalains in evolution: Why mutual exclusion remains the best‐supported model

open access: yesPlant Biology, EarlyView.
Anthocyanins and betalains are plant pigments produced through different biosynthetic pathways and are generally considered mutually exclusive. We examine claims of their co‐occurrence, arguing that methodological flaws and data misinterpretation have led to unsupported reports, and offer recommendations for more rigorous future research.

Diel net CO2 exchange of carnivorous Pinguicula is consistent with low‐level CAM photosynthesis

open access: yesPlant Biology, EarlyView.
In carnivorous butterworts (Pinguicula), CO2 uptake occurs primarily in the light via C3 photosynthesis, yet low‐level CAM photosynthesis, including net CO2 dark fixation, significantly improves the carbon balance of plants, especially under water‐deficit conditions.

Qualitative Analysis by High-Performance Thin-Layer Chromatography–Bioautography of Ecuadorian Chenopodium quinoa Willd. Leaves: Influence of Variety, Phenological Stage, and Place of Cultivation on Free Radical Scavenging and α-Amylase Activity

open access: yesNutraceuticals
The present study aimed to qualitatively assess the influence of Chenopodium quinoa Willd. varieties (INIAP-Tunkahuan, INIAP-Pata de Venado varieties and Chimborazo genotype), phenological stages (40, 60, and 80 days), and places of cultivation ...

Nomenclature Survey of the Genus Amaranthus (Amaranthaceae). 13. The Identity of Amaranthus tortuosus

open access: yesFeddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT The name Amaranthus tortuosus, a species described by Hornemann in 1819, is currently treated in different ways, either as an accepted name, as a synonym of A. dubius or A. hybridus s.str., or as an unplaced name. In order to clarify its application, we reassessed its taxonomic identity within the genus Amaranthus.

A comprehensive checklist of Mediterranean wild edible plants: Diversity, traditional uses, and knowledge gaps

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1616-1633, September 2026.
The use of wild edible plants and the traditional knowledge associated with them are rapidly disappearing across the Mediterranean, with serious consequences for biodiversity, cultural heritage, and regional food security. This study compiles and organizes fragmented information to create the first comprehensive catalogue of these plants across the ...
