Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Bee pollen as functional food and environmental bioindicator: current evidence and future challenges

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Bee pollen (BP), a plant‐derived product collected by honey bees, is increasingly promoted as a functional food due to its content of proteins, essential amino acids, lipids, vitamins, minerals, and bioactive compounds such as polyphenols and flavonoids.

Macro‐ and micromorphological insights into Iranian Onobrychis subgenus Onobrychis Miller (Fabaceae): exploring fruit traits for taxonomic clarity

Nordic Journal of Botany, EarlyView.
This study provides a comprehensive examination of fruit morphology and micromorphology characteristics of 28 populations of Onobrychis subgenus Onobrychis taxa from Iran, using both light and scanning electron microscopy. For each trait, 25 replicates were analyzed, encompassing a wide range of qualitative and quantitative traits.

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over
