Habitat destruction and fragmentation accelerate pollinator decline, consequently disrupting ecosystem processes such as pollination. To date, the impacts of multilevel spatial structure on pollination services have rarely been addressed. We focused on the effects of population spatial structure on the pollination services of Comarum palustre at three levels (i.e. within-population, between-pop...

To understand the reproductive ecology of a plant species with both selfing and outcrossing systems, it is important to know how selfed individuals contribute maintenance population. Further, examination magnitude inbreeding depression after pollination essential for accurate measurement success. In this study, we investigated characteristics viable seeds seedlings Rhododendron kaempferi in reg...

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...

Many recent studies have suggested that the majority of animal-pollinated plants have a higher diversity of pollinators than that expected according to their pollination syndrome. This broad generalization, often based on pollination web data, has been challenged by the fact that some floral visitors recorded in pollination webs are ineffective pollinators. To contribute to this debate, and to ...

Floral odor is a key trait for pollinator attraction in many plants, but may also direct antagonists like herbivores to flowers. In this study, we examined how floral scent changes after pollination in Silene latifolia, which has a specialized relationship with the seed predator Hadena bicruris. We found an overall decrease in total scent emission and considerable changes in relative amounts of...

Various aspects of the reproductive success of Garcinia atroviridis Griff. were studied. Controlled pollination experiments were carried out in an orchard located in Songkhla province, southern Thailand, from February to July 2003. Floral longevity, stigma receptivity, and pollen viability were examined before carrying out the experiments. Three pollination treatments were compared: open pollin...

Small-scale soil disturbances such as soil mounds produced by gophers are known to influence local plant communities. A variety of mechanisms might account for the influence of gopher disturbances on individual plant success, but understanding of these mechanisms is not well developed. Disturbances are often assumed to affect plants through changing competition or the abiotic environment, but d...

The Orchidaceae are one of the most species-rich plant families and their floral diversity and pollination biology have long intrigued evolutionary biologists. About one-third of the estimated 18,500 species are thought to be pollinated by deceit. To date, the focus has been on how such pollination evolved, how the different types of deception work, and how it is maintained, but little progress...
