Precision Monitoring of Honey Bee (Hymenoptera: Apidae) Activity and Pollen Diversity during Pollination to Evaluate Colony Health

Insects, 2023
Certain crops depend upon pollination services for fruit set, and, of these, almonds are of high value for Australia. Stressors, such as diseases, parasites, pesticides, and nutrition, can contribute to honey bee Apis mellifera L. colony decline, thereby

Importance of bee pollination for cotton production in conventional and organic farms in Brazil

Journal of Pollination Ecology, 2014
This study aimed to evaluate the importance of wild bee and feral honeybee visits for cotton production on conventional and organic farms. Experiments were conducted in Brazil, on a conventional cotton farm in Mato Grosso state in the Amazon biome and on

Flight of the bumble bee: Buzzes predict pollination services.

PLoS ONE, 2017
Multiple interacting factors drive recent declines in wild and managed bees, threatening their pollination services. Widespread and intensive monitoring could lead to more effective management of wild and managed bees.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Nectar production and pollination in peach

International Journal of Horticultural Science, 2000
Observations were made at two growing sites, Siófok and Szatymaz, in the years 1998 and 1999, on 16 peach varieties. The production of nectar was measured, the foraging behaviour of bees, fruit set and the effect of exclusion of bee visits for different ...

Pollen samples from a bumble bee (Hymenoptera: Apidae) collection show historic foraging on introduced and native plants in the South Island of New Zealand.

PLoS ONE, 2022
Historic pollination networks are important to understand interactions between different plant and pollinator species, as well as to differentiate between causes and consequences of present insect population decline.

What's in a name? Challenging the commodification of pollination through the diverse economies of 'Bee Cities'

Journal of Political Ecology, 2021
One million species are threatened with extinction globally,including more than half of the native bee species in North America. In Canada,as of July 2020, 42 municipalities have signed a resolution to commit to the standards of the Bee City Canada ...

Tropical bee species abundance differs within a narrow elevational gradient

Scientific Reports, 2021
Insect pollination is among the most essential ecosystem services for humanity. Globally, bees are the most effective pollinators, and tropical bees are also important for maintaining tropical biodiversity.

Potential landscape-scale pollinator networks across Great Britain: structure, stability and influence of agricultural land cover [PDF]

, 2018
Understanding spatial variation in the structure and stability of plant-pollinator networks, and their relationship with anthropogenic drivers, is key to maintaining pollination services and mitigating declines.
