Text and Topos: British Travellers to Real‐and‐Imagined Classical Sites, c. 1560–1820

History, Volume 110, Issue 393, Page 588-605, December 2025.
Abstract Early‐modern British travellers to the Mediterranean often understood their journeys through the lens of classical texts and culture. Historians sometimes explain this as an imaginative phenomenon: travellers’ preconceptions shaped by classical knowledge guided their subsequent comprehension and activity.

Biochar Permanence—A Policy Commentary

GCB Bioenergy, Volume 17, Issue 12, December 2025.
ABSTRACT The application of biochar to soil is a highly durable nature‐based carbon dioxide removal (CDR) pathway. It provides certifiable climate‐change mitigation, with mean carbon residence times exceeding 1,000 years, and additional co‐benefits for soil health and fertility.

Needle‐ and Canopy‐Level Genetic Variation in Scots Pine (Pinus sylvestris L.) Revealed by Hyperspectral Phenotyping Across Sites and Seasons

Evolutionary Applications, Volume 18, Issue 11, November 2025.
ABSTRACT As an essential species across European forests, Scots pine (Pinus sylvestris L.) plays a vital ecological and economic role, yet its physiological variability underlying its adaptive potential remains underexplored. Understanding this intraspecific variability is crucial for uncovering the genetic basis of adaptation.
