The article in Science (volume 391, number 6780, pages 42-44, January 1, 2026) is part of the In Science Journals section and presents highlights from the Science family of journals[1][6]. The title page shows a bison moving through Yellowstone's Lamar Valley in the east at dawn[6]. Bison movements and grazing accelerate the nitrogen cycle, increasing the annual nutritional value that plants provide to herbivores[6]. After decades of restoration, bison add heterogeneity that sustains soil nutrient storage and plant productivity[6]. Thereby they enable plant communities to become more diverse[6]. The article emphasizes the importance of restoring the original shepherds in large numbers with freedom of movement[6]. Photo by NPS/Jacob W. Frank[6].
