Pollination of lark daisy on roadsides declines as traffic speed increases along an Amazonian highway
Ecological disturbances caused by roadways have previously been reported, but traffic speed has not been addressed. We investigate effects of traffic speed on pollination of Centratherum punctatum (Asteraceae) along an Amazonian highway roadside. We hypothesised that frequency of flower visitors, du...

Ecological disturbances caused by roadways have previously been reported, but traffic speed has not been addressed.
