Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Palaeoenvironmental and climatic changes from the lateglacial of the Saalian to the Late Weichselian in central Poland: a multiproxy study from Józefów

open access: yesBoreas, EarlyView.
Józefów site is a case study which provides a detailed record of environmental and climate changes and confirms the main traces of the landscape morphogenesis of the Late Pleistocene established in central‐eastern Europe. This study presents a multiproxy reconstruction of palaeoenvironment under variable climatic conditions from the retreat of the ...

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.

Evaluating sampling strategy for DNA barcoding study of coastal and inland halo-tolerant Poaceae and Chenopodiaceae: A case study for increased sample size. [PDF]

open access: yesPLoS ONE, 2017
Environmental conditions in coastal salt marsh habitats have led to the development of specialist genetic adaptations. We evaluated six DNA barcode loci of the 53 species of Poaceae and 15 species of Chenopodiaceae from China's coastal salt marsh area ...

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.

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.

Phytochemical Profiling and Biological Evaluation of Anthyllis henoniana Organs: Integrated In Vitro and Molecular Docking Insights Into Antioxidant, Anti‐Inflammatory, and Cytotoxic Potential

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Anthyllis henoniana aerial parts were subjected to fractionated extraction. Methanolic fractions yielded high total phenolic and flavonoid contents with strong antiradical (anti‐DPPH) and neuroprotective (anti‐AChE) activities, whereas dichloromethane and cyclohexane fractions demonstrated potent cytotoxicity (anti‐MCF‐7, anti‐HCT‐116) and anti ...
