Chemical Profiling, In Silico and In Vitro Studies to Identify Potential CDK2 and mTOR Inhibitor From Selaginella inaequalifolia (Hook. & Grev.) Spring Ethanolic Extracts

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
ABSTRACT The current study is aimed to reveal the phytoprofile of Selaginella inaequalifolia (Hook. & Grev.) Spring using GC–MS and predict the drug properties, toxicity, biological properties of S. inaequalifolia ethanolic extracts (SiEE) using in silico methods and in vitro toxicity assays, namely, MTT and BSLB assay.

The Soil Erosion Paradox Re‐Examined: Alluviation and Land Use History in a Small British Lowland River Catchment in the Late Holocene

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Modern studies show that soil erosion results in a loss of ecosystem function, particularly fertility, and is a cause of declining agricultural yields. However, despite the well‐attested high rates of soil erosion across Roman and medieval Europe there appears to have been little or no soil‐associated decline in agricultural production—the ...

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...
