To better understand the behavior of these plants over time in both humid and dry forests, researchers from approximately 60 institutions analyzed data from over 1,500 areas of forest regeneration across the Americas. The results, published in the journal Nature Plants, indicate that the initial dominance of exotic species is temporary. They multiply easily during the first 10 to 20 years, taking advantage of abundant sunlight in open areas. However, they decline as native trees grow and shade the forest.","pubDate":"Thu, 22 Oct 2026 17:20:10 EDT","url":"https://phys.org/news/2026-10-natural-forest-regeneration-curb-invasive.html"},"indexado":"2026-10-22T21:22:18.923Z"}}
