Spatial and temporal hotspots of termite‐driven decomposition in the Serengeti

Termite activity in the Serengeti National Park exhibits pronounced spatial and temporal hotspots, particularly concentrated at the top positions of the landscape gradient during the dry season. This study reveals that termites play a significant role as ecosystem engineers by influencing decomposition rates of grass litter and dung, with their consumption patterns varying distinctly between wet and dry seasons. Unlike the wet season, where no positional effect was observed, the dry season saw higher termite activity at elevated catena positions. These hotspots of termite activity overlap with those of mammalian herbivores and predators, suggesting complex interactions within the ecosystem. The research employed field experiments to map termitaria and bait removal patterns, highlighting the need for greater consideration of intraspecific spatial heterogeneity and temporal variability in understanding ecosystem dynamics.
