Summary: OIKOS 91: 409420. Copenhagen 2000
Minireviews provides an opportunity to summarize existing knowledge of selected
ecological areas, with special emphasis on current topics where rapid and significant
advances are occurring. Reviews should be concise and not too wide-ranging. All key
references should be cited. A summary is required.

The ecological significance of toxic nectar
Lynn S. Adler
Adler, L. S. 2001. The ecological significance of toxic nectar. - Oikos 91: 409420.
Although plant-herbivore and plant-pollinator interactions have traditionally been
studied separately, many traits are simultaneously under selection by both herbivores
and pollinators. For example, secondary compounds commonly associated with
herbivore defense have been found in the nectar of many plant species, and many
plants produce nectar that is toxic or repellent to some floral visitors. Although
secondary compounds in nectar and toxic nectar are geographically and phylogenet-
ically widespread, their ecological significance is poorly understood. Several hypothe-
ses have been proposed for the possible functions of toxic nectar, including
encouraging specialist pollinators, deterring nectar robbers, preventing microbial
degradation of nectar, and altering pollinator behavior. All of these hypotheses rest
