| contrasting pollinators and pollination in native and non-native regions of highbush blueberry production. | highbush blueberry yields are dependent on pollination by bees, and introduction of managed honey bees is the primary strategy used for pollination of this crop. complementary pollination services are also provided by wild bees, yet highbush blueberry is increasingly grown in regions outside its native range where wild bee communities may be less adapted to the crop and growers may still be testing appropriate honey bee stocking densities. to contrast crop pollination in native and non-native pr ... | 2016 | 27391969 |
| lack of pollinators limits fruit production in commercial blueberry (vaccinium corymbosum). | modern agriculture relies on domesticated pollinators such as the honey bee (apis mellifera l.), and to a lesser extent on native pollinators, for the production of animal-pollinated crops. there is growing concern that pollinator availability may not keep pace with increasing agricultural production. however, whether crop production is in fact pollen-limited at the field scale has rarely been studied. here, we ask whether commercial highbush blueberry (vaccinium corymbosum l.) production in new ... | 2014 | 25313694 |
