While researching a topic, a student has taken the following notes:
- In a 2005 study, Rotundo and Aguiar tested the effect of plant litter on seedling emergence in a grassland setting.
- Plant litter includes dead leaves and other plant material.
- The test site was a dry grassland in Argentina.
- It was in a midlatitude/semidesert climate.
- The researchers found that in these environmental conditions the presence of plant litter had a positive effect on seedling emergence.
