Recent pollen rain analysis in Akoko environment as indicator of the vegetation of Ondo State, Nigeria
The study of Atmospheric Pollen Content (APC) in Akoko environment provides standard baseline information on environmental change, vegetation type, species composition and their utilization for sustainable development. This study was carried out in twenty randomly selected locations to examine the t...

The study of Atmospheric Pollen Content (APC) in Akoko environment provides standard baseline information on environmental change, vegetation type, species composition and their utilization for sustainable development. This study was carried out in twenty randomly selected locations to examine the temporal and spatial relationship between the atmospheric pollen content and their vegetation. The palynomorphs were collected with Modified Tauber Sampler using simple random sampling technique and analyzed palynologically. Results showed 182 pollen types belonging to 76 angiospermic plant families were encountered.
