The annual Research Tour was held Feb. 1, 2025, in the Duke Forest, a 7,000-acre living laboratory dedicated to environmental research and education. Among the featured projects was a groundbreaking study led by Dr. Tong Qiu from the Duke University Nicholas School of the Environment, focusing on forest regeneration and biodiversity in the face of climate change. Qiu’s research investigates how climate shifts and habitat changes affect global forest seed production—a critical factor in forest regeneration and ecosystem health. “I’m interested in how many seeds a tree can produce,” Qiu explained, noting that seed production is influenced by factors like temperature, phenology, and nutrient availability. To measure seed production, Qiu’s team employs both traditional methods, like binocular observations, and advanced technology like his state-of-the-art terrestrial laser scanner—one of only six in use at universities nationwide. This 360-degree, high-resolution scan allows researchers to analyze individual branches and distinguish seeds from leaves. READ MORE.
