Guanidine Ligands as Versatile Scaffolds for the Development of Antitumor Ruthenium–Based Metallodrugs

Bioinorganic Chemistry and Applications, Volume 2026, Issue 1, 2026.
The straightforward catalytic synthesis of guanidine ligands has been evaluated as a strategy for rapidly developing ruthenium metallodrugs as antitumor agents. A series of structurally guanidine ligands, obtained via guanylation reactions, were used as scaffolds for generating RAPTA‐C derivatives.

Contrasting effects of vertebrate and invertebrate herbivores on leaf litter decomposition in terrestrial ecosystems: A meta‐analysis

Functional Ecology, Volume 39, Issue 12, Page 3372-3384, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivores influence litter quality, soil properties and decomposer communities, with cascading effects on litter decomposition. Vertebrate and invertebrate herbivores can affect decomposition through the same two pathways (litter quality‐ and soil‐mediated) but are ...

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

Biotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.

Do Formal Stance Strategies Reveal Disciplinary Variation in Professional Scientific Writing?

International Journal of Applied Linguistics, Volume 35, Issue 3, Page 1242-1261, August 2025.
ABSTRACT Stance in academic discourse has been extensively studied, with numerous investigations indicating that its expression varies across disciplines, depending on the authors’ intention to either enhance or diminish their voice or presence (e.g., It seems fairly certain vs. This is based on the belief that…).
