La temperatura y radiación solar explican diferencias en la distribución de dos árboles altoandinos (Polylepis spp.) localmente simpátricos en la Cordillera Blanca, Perú

Research reveals that temperature and solar radiation are key factors shaping the distribution of two high-altitude Polylepis tree species, Polylepis albicans and P. weberbaueri, within Huascarán National Park (HNP) in Peru's Cordillera Blanca. These species exhibit distinct ecological niches, with P. albicans thriving in warmer, drier conditions while P. weberbaueri prefers cooler, more humid environments. This spatial segregation suggests differing conservation needs for each species. Using niche modeling, Canonical Correspondence Analysis (CCA), and generalized linear models (glm), the study estimated their current forest cover within HNP—approximately 24,000 hectares in total—challenging prior estimates and highlighting HNP's critical role as a stronghold for both species. The findings underscore the importance of targeted management strategies to preserve these unique ecosystems.
