  • Buttress trees are prominent in tropical rainforests, providing mechanical support for canopy trees. Other ecological functions of these structures remain unclear. Here we demonstrate that buttresses are physical structures that regulate soil moisture, soil nutrient status and seedling diversity near tree trunks. We monitored soil moisture over a year in plots on the uphill, downhill and lateral sides of buttresses on a tropical seasonal rainforest slope in Xishuangbanna, Southwest China. Soil… CONTINUE READING
