Habitat and Pollinator
-
Most orchid species have been shown to be severely pollination limited, and the factors affecting reproductive success have been widely studied. However, the factors determining the reproductive success vary from species to species.

As the most significant pollinators of wild plants, bees play an important role in sustaining the natural ecosystems. In this study, we conducted surveys of bee fauna of three different habitat types during dry and rainy seasons of 2020 in Binh Chanh District, Ho Chi Minh City. A total of 169 individuals from 13 bee species belonging to six genera were collected.

The study was undertaken at Raj Mohini Devi College of Agriculture and Research Station, Ambikapur during 2017-18 for diversity of insect pollinators/ visitors in bitter gourd ecosystem. Different insect pollinators/ visitors i.e. Apis dorsata, A. indica, A. florea, xylocopa, black ant and small ants were recorded in different fluorescent colored pan trap i.e. White, yellow and blue at different flowering period onset of bloom, full bloom and end of bloom of bitter gourd.

Fragmentation of habitats by roads, railroads, fields, buildings and other human activities can affect population size, pollination success, sexual and asexual reproduction specially in plants showing pollinator limitation, such as Mediterranean orchids.

The pollination success of two nonrewarding orchids in two coarse habitats was examined. The comparative results of Orchis punctulata and O. purpurea showed a significant differentiation. The fruit set of O. purpurea was significantly greater compared to O. punctulata, whereas both species also had significantly higher fruit set in the grassland compared to the forest.

Because of the primary character of biomass ecosystem production and the comprehensive coverage of carbon/biomass accounts, they play a central role in ecosystem capital accounts. Carbon/ biomass is the primary service expected from the ecosystem, under the constraint of sustainable supply of water (for human use and the ecosystem itself) as well as sustainability of all the regulating (water regulation, assimilation of residuals, habitat regulation, pollination) and socio-cultural services which are produced.
