Bees may get sucrose-or hexose-dominated nectars, but this is complicated by the fact that some plant families have either sucrose- or hexose-dominated nectars.
Now add a few bees to this community of birds, sufficiently few that their intake of nectar is negligible.
The question is: how many birds and bees should forage at the red and blue patches so that their intake of nectar is maximised?
The most widespread plant feature that attracts ants, however, is extrafloral nectar, produced from special glands.
There is no sign of nectar or any pollinator reward other than pollen in male flowers.
The flower visitation behaviour of a bat over the night seems to be shaped by a combination of intrinsic physiological factors and by nectar availability.
Our data clearly revealed a need for more studies on the effects of nectar production on fruit- and/or seed-set.
Seed production from experimental flowers was then contrasted with those naturally exposed to pollination and nectar removal.
