Since 1973, when Herbert and Irene Baker first documented the widespread occurrence of amino acids in plant nectars, a wide variety of studies have shown that: 1) plants with different pollinators produce nectars with different amino acid concentrati

This study was designed to compare the chemistry of elaiosomes of three sympatric species ofTrillium to discover if there are correlations between chemistry and dispersal rates by ants. We quantified the amount of proteins and neutral lipids and qual

Amino acids occur in most floral nectars but their role in pollinator attraction is relatively unstudied. Nectars of butterfly-pollinated flower tend to have higher concentrations of amino acids than do flowers pollinated by bees and many other anima

In many plants, extrafloral nectars attract ants that protect the plant from herbivory. Previous work indicates that both sugars and amino acids contribute to ant attraction and that herbivory may affect nectar production or composition. This study w

Although the volume and chemical composition of nectars are known to vary among plant species and to affect pollinator response to plants, relatively little is known of the variation in volume, and sugar and amino acid composition within species. We

Fly-pollinated flowers tend to have higher levels of amino acids in their floral nectars than flowers pollinated by other insects. The feeding preferences of flies, over evolutionary time, may account for these high levels of amino acids. To address
