Exploring how disturbance and light availability shape the elevation ranges of multiple mountain tree and shrub species in the tropics

Disturbance and light availability are critical factors shaping the elevation ranges of tropical mountain tree and shrub species, according to a study in the Talamanca Range-La Amistad Reserves. The research found that canopy openings created by disturbances provide essential habitat for high-elevation species, enabling them to persist under warmer conditions. Using distance sampling transects along a 1400 m elevation range and density surface models, the study analyzed nine species, revealing context-dependent light requirements—some shifted from shade tolerance to strict light demand across their elevation range, while others thrived in shaded, crowded conditions. These findings highlight the importance of considering disturbance dynamics in conservation strategies for high-elevation plant species.
