This means that pollen transferred within a patch contributes to geitonogamous self-pollination.
Secondly, inflorescences were visited by numerous nitidulids almost always loaded with pollen.
The airstream directs the pollen up a tube having openings, at several different points along its length, through which the pollen is dispersed.
Pollen records poorly reflect cyclical droughts seen in isotopic records, as natural vegetation has adapted to these fluctuations.
Some core sections had decreased in length due to dewatering since the cores were originally collected and sampled for pollen and microscopic charcoal in 1989.
The total number of pollen grains, the number and percentages of species-specific grains and recognizable heterospecific pollen types are shown.
The following sequence of floral parameters was noted: anthesis, odour release, nectar secretion, pollen liberation, and receptivity of stigmas.
The attraction of both predators to the leaves containing pollen may be the reason for the lower levels of predation on the plants containing pollen.
