Phenanthrene Alkaloids From Guatteria Olivacea as Topoisomerase II Inhibitors: Theoretical Insights and Cytotoxic Evaluation

ChemistrySelect, Volume 11, Issue 2, 15 January 2026.
Three phenanthrene alkaloids from Guatteria olivacea were studied by DFT, docking, MD, and cytotoxicity assays. All compounds showed stable binding to DNA–topoisomerase II and human serum albumin. Atherosperminine exhibited cytotoxic activity against four cancer cell lines, supporting its potential as a topoisomerase II inhibitor and anticancer ...

Flowers for habitat enhancement primarily benefit common insect pollinators across temperate grasslands

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Flowers that are attractive and occupy a complementary position in interaction space could be prioritized in flower mixes to recover rare and specialized pollinators. By defining the ecological roles of readily available plants in plant–pollinator networks, particularly those that receive high visitation rates from complementary pollinator communities,

Measurement of Ungulate Palatability and Browsing Pressure on Japanese Flora

Ecological Research, Volume 41, Issue 1, January 2026.
Estimation of palatability and browsing pressure are key techniques for ecosystem management. We compared four methods to estimate palatability based on browsing scar survey and proposed the reference palatability values for the Japanese flora as plant ecological trait.

Phylogenomic Barcoding of Soil Seed Bank–Persistent and Wind‐Dispersed Non‐Native Plant Species in South Georgia

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Climate change and invasive species are leading drivers of biodiversity loss, with island ecosystems being especially vulnerable. South Georgia, a remote sub‐Antarctic island, is 170 km long with approximately 30,000 ha of vegetated coastal areas, as snow and ice dominate the inland regions.
