| | 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. |
