From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Pollen diet for in vitro rearing of africanized honey bee larvae, Apis mellifera (Hymenoptera: Apidae)

Bioscience Journal, 2013
Pollen is the major protein source for honey bees, Apis mellifera. It is essential for the adults to produce royal jelly to feed the larvae. Young larvae receive the brood food, whereas the older (over 3 days old) larvae receive pollen in addition to ...

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, EarlyView.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

Journal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

JSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...
