  Fish in ponds benefit flowering plants
Most visitors near ponds with fish were hymenopterans, — for the most part, bees — compared with most visitors at the fish-free ponds, mainly flies.
The effect of reduced pollinator visits near fish-free ponds might be magnified, Knight said, in part because the few visits pollinators made to the area were from flies and moths, rather than bees.
The researchers also found that pollinators tend to avoid fish-free ponds because of the presence of dragonflies.

 Fish in ponds benefit flowering plants
A team of researchers, headed by Tiffany Knight, Ph.D., Washington University assistant professor of biology in Arts & Sciences, has shown a correlation between the presence of fish in ponds and well-pollinated St. John's wort (Hypericum fasciculatum, Hypericaceae) at a Florida research station.
Most visitors near ponds with fish were hymenopterans, -- for the most part, bees -- compared with most visitors at the fish-free ponds, mainly flies.
Hypericaceae have evolved traits that attract bees, and so bees may be better pollinators of Hypericum than flies.
