Nevertheless, there are experimental results showing that pollination by honey bees and bumble bees can increase cotton yields [20] and pollinators contribute to extent and distance of outcrossing [18, 19, 21].
And in Queens, students and teachers cultivated flowers that attract butterflies and pollinators.
We are encouraging the government to adopt a Pollinator Action Plan to protect all bees and pollinators.
Composite flowers offer some of the best floral rewards, and pollinators have taken notice: bumblebees, syrphid flies, honeybees.
"Most roses will set hips in an attempt to reproduce if conditions are right and pollinators are present," she said.
It made use of a remarkable record made of plants and pollinators at Carlinville, Illinois between 1888 and 1891 by entomologist Charles Robertson.
We hope through raising awareness of the intrinsic value of bees and pollinators, we can promote positive public action to save them.
Inland wetlands, for instance, are worth £1.5bn a year in improving water quality alone, and pollinators such as bees are worth at least £430m a year to agriculture.
For example, the complex interlinkages with the impacts of climate change on pests, diseases and pollinators, like bees, are largely unknown.
They point to findings such as the sharp decline in farmland birds and small mammals and pollinators, which has accompanied intensive farming in the UK.
Daniel Song, a doctoral student at the University of Pennsylvania, writes from Hovsgol National Park, Mongolia, where he is studying how plants and pollinators form interaction networks.
