Preface of Special Feature “Current topics on cycad biology: Deciphering the Rosetta Stone of plant evolution.” Part II: Perspectives from natural history

Plant Species Biology, Volume 40, Issue 6, Page 527-529, November 2025.
Often regarded as “living fossils,” cycads are well known for retaining many ancestral traits, which makes them particularly fascinating to naturalists and scientists alike. Cycads provide insights into the functional and developmental processes underlying the origin and diversification of seed plants, and they may help clarify how they colonized the ...

Synergistic Effects on the Mechanical, Thermal, and Morphological Properties of HDPE Composites Reinforced With Walnut Shell and Nano‐Calcium Carbonate

Journal of Applied Polymer Science, Volume 142, Issue 37, October 5 2025.
This study explores the mechanical properties of HDPE‐based composites reinforced with walnut shell (WS) and Nano‐CaCO3. The addition of Nano‐CaCO3 enhanced tensile and flexural strength, demonstrating its reinforcing effect. These findings highlight the potential of HDPE/WS/Nano‐CaCO3 composites for structural applications, offering insights into ...

Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

Ecography, Volume 2025, Issue 9, September 2025.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.
