An analysis of modern pollen representation and climatic conditions on the Galápagos Islands

A groundbreaking pollen trapping study on the Galápagos Islands reveals significant long-distance dispersal of pollen, particularly from mainland and neighboring islands, especially in areas with low local pollen production. The research identified distinct habitat types through pollen analysis and documented the over- and under-representation of ecological dominants, including invasive exotic species. Climate data highlighted the cooling effect of ground-level clouds (garúa) on highland temperatures, emphasizing its crucial role in the conservation of the islands' endemic flora. Conducted across four islands—Genovesa, Rocas Bainbridge, Santa Cruz, and San Cristobal—the study used HOBO data loggers to collect temperature, humidity, and dew point data every 30 minutes for a year, providing insights into modern pollen representation and climatic conditions.
