Synthesis of Novel Dihydropyridine‐Iminium Salts Containing a Selenazine Core

Asian Journal of Organic Chemistry, Volume 14, Issue 10, October 2025.
An efficient method to develop novel dihydropyrido[3,2‐e][1,3]selenazines iminium salts. A comparative study of the key reagent selenourea towards thiourea and urea was carried out to assess the contribution of chalcogen to the pathway. DFT (density functional theory) calculations have predicted the optimized minimum energy structure for the hybrid ...

Urbanization Drives Habitat Suitability of the Invasive Cuban Knight Anole (Anolis equestris) in Florida, USA

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study evaluates the climatic and anthropogenic factors driving the habitat suitability of the invasive Cuban knight anole (Anolis equestris) in Florida and its potential impact on three threatened invertebrate species through habitat overlap. Using species distribution models (SDMs), we found that urbanization strongly influences the anole's ...

A taxonomic sudoku: Resolving the long‐standing puzzle of Japanese Dictyoteae (Dictyotales, Phaeophyceae) with new records and biogeographic insights

Journal of Phycology, Volume 61, Issue 5, Page 1457-1485, October 2025.
Abstract Japanese Dictyoteae have been documented since 1838, with a historical checklist of 21 names recorded prior to 1990. Persistent misidentifications—particularly of species originally described from Europe and the Americas—have complicated the taxonomy of the group in Japan.

Plants maximise chloride uptake during early vegetative development to stimulate cell expansion, maturation of the photosynthetic apparatus, and growth

The Plant Journal, Volume 123, Issue 5, September 2025.
SUMMARY Despite being an essential micronutrient and its recent classification as a beneficial macronutrient, chloride (Cl−) has traditionally been considered of limited agricultural relevance and a potentially toxic saline ion. This study provides the first comprehensive demonstration of the quantitative and qualitative importance of Cl− during early ...
