Abstract Pollinator richness, abundance and visitation frequency may be affected by the of floral resources abiotic factors, influencing plant reproductive success. We analysed whether diversity, butterfly on Lantana camara vary across year in a tropical urban landscape this variation community influences plant’s A two-period survey, referred to here as rainier drier seasons, was carried out 12...

In order to prevent self-pollination in some plants like corn, tomato and cabbage, emasculation of the female line by hand is required, raising costs and labor expenses of seed production.

Mostly correlated with changes in the mitochodrial or chloroplast DNA, in some lines of distinct species...
