In successionally older forests more nitrogen was added by nitrogen fixation than was deposited from the atmosphere. Pleurozium started to play a significant role in nitrogen availability about 100 years after a fire but the amount of nitrogen added by nitrogen fixation never surpassed the …
Pleurozium is a loose moss that grows over plant foliage on the forest floor. It has a great impact on older forests where it adds more nitrogen to the soil through nitrogen fixation process deposited from the atmosphere ; after forest fires their impact isn't seen immediately but over time it …
Interpret the Data The feather moss Pleurozium schreberi harbors species of symbiotic nitrogen-fixing bacteria. Scientists studying this moss in northern forests found that the percentage of the ground surface “covered” by the moss increased from about 5% in forests that burned 35 to 41 years ago to about 70 % in forests that burned 170 or...
