Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake
Ecological Research, Volume 41, Issue 6, November 2026.We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.ABSTRACT This research assessed the feasibility of using the yeast Saccharomyces cerevisiae as a complementary feed for the mangrove cockle Anadara tuberculosa spat. The nutritional impact of five mix diets was tested: (1) Tisochrysis lutea + Chaetoceros gracilis, (2) C. gracilis + S. cerevisiae, (3) S. cerevisiae, (4) T. lutea + S.

Ecology and Evolution, Volume 16, Issue 10, October 2026.We report the first discovery of wild double‐flowered populations of the alpine dwarf shrub Rhododendron nivale on the eastern Qinghai‐Tibet Plateau. Two geographically isolated populations (> 800 km apart) show nearly identical stamen petaloidy and floral modifications in similar harsh high‐altitude habitats, suggesting possible parallel evolution ...
