The study looked at how the amount of plant material below the ground in alpine grasslands changes with altitude. They found that as altitude increases, the amount of belowground plant material also increases. This was true for different types of grasslands with different dominant plant species. The amount of belowground plant material was highest in the top 10 cm of soil. The researchers also found that the amount of belowground plant material was linked to factors like air temperature, humidity, and soil water content. Overall, higher altitudes had more belowground plant material, and this was influenced by environmental factors like temperature and moisture.
