Temperature sensitivity of gross production and consumption rates of glucosamine, l-alanine, and d-alanine in soils from six sites differing in bedrock and land management. The temperature sensitivity was calculated for 5 °C, 15 °C, and 25 °C based on a linear regression model. Values are means ± SE (n = 4). Significant effects of land management and bedrock were analyzed by two-way ANOVA.
