Plants developed features to attract pollinators, which is called pollination syndromes.
L. camara has characteristics that fit the syndrome of pollination by butterflies.
Butterflies, like other pollinators may or may not, pollinate flowers. This efficiency or
success in pollination may be interfered from the size of proboscis, visitation rate, and
precipitation. For this reason, the chapters of this study address the following questions:
(1) Do the variations in rainfall at affect the reproductive success of L. camara and the
richness, abundance and rate of visitation of butterflies? and (2) Does the proboscis size
and the rate of floral visitation influence pollinator efficiency of butterflies?, the
Amazon has two on seasons, which are the seasons of more rain and less rain. This
study was done through observations for three months in each season. We analyzed 18
bushes of L. camara occurring in an Amazonian forest fragment. Comparisons were
made between: concentration and volume of L. camara and in nectar each season; size
of proboscis and visitation rate of butterflies; richness an each abundance of species of
butterflies; diversity, abundance and rate of floral visits of butterflies; diversity,
abundance of butterflies and the fruits generated by L. camara; visit rate of butterflies
and the reproductive success of L. camara; butterflies pollinating efficiency and fruit
formation in L. camara in each season; diversity of flower visiting in butterflies in every
each season. Our data show that the nectar and the reproductive success of L. camara
were differents in season. When there is less rain, the plant has a higher quantity of
flowers and higher nectar concentrations. The reproductive success of L. camara is
greater when there is visitation by butterflies. The butterfly visitation rate is higher
when there a greater richness and abundance of butterflies, in the less raining season.
We found that what affects butterflies pollination efficiency is the visitation rate and not
the size of proboscis, where the higher rate of visits, the greater reproductive success of
the plant. Therefore, there was higher fruiting rate of the plant in periods of lower
rainfall. This shows the relationship between abiotic factors, such as precipitation, with
plants and their floral visitors. We conclude that the increase in butterflies diversity
influences the reproductive success of L. camara. |
