摘要：

Mounds were characterized by lower soil nutrient and organic matter concentrations, higher light intensities and greater diurnal temperature fluctuations than adjacent undisturbed areas. Temperatures during prescribed spring fires were significantly lower on mounds and near burrow openings relative to the surrounding undisturbed vegetation. Mounds undergo microsuccession and contribute toward increased plant species diversity in the forest understory. Old mounds had the highest species richness per unit area. Gopher tortoise disturbances increased the frequency of recruitment by seed relative to vegetative reproduction in the common rhizomatous forb, Pityopsis graminifolia. -from Authors
