Using citizen science to monitor pollination services [PDF]

, 2015
1. Pollination by insects is a vital ecosystem service and the need for its assessment is increasing in recognition and political pressure, but there are currently no large-scale systematic monitoring schemes in place to measure the direct provision of ...

Pollination Efficiency and the Evolution of Specialized Deceptive Pollination Systems [PDF]

The American Naturalist, 2010
The ultimate causes of evolution of highly specialized pollination systems are little understood. We investigated the relationship between specialization and pollination efficiency, defined as the proportion of pollinated flowers relative to those that experienced pollen removal, using orchids with different pollination strategies as a model system ...

A horizon scan of future threats and opportunities for pollinators and pollination [PDF]

PeerJ, 2016
Background. Pollinators, which provide the agriculturally and ecologically essential service of pollination, are under threat at a global scale. Habitat loss and homogenisation, pesticides, parasites and pathogens, invasive species, and climate change have been identified as past and current threats to pollinators.

Honey bee immune response to trace concentrations of clothianidin goes beyond the macronutrients found in artificial diets

Scientific Reports
Honey bees (Apis mellifera) often encounter a variety of stressors in their environment, including poor nutrition and pesticides. These stressors interact and can be exacerbated in large-scale agroecosystems.

Pollination Ecology of Rocket (Eruca vesicaria (L.) Cav. ssp. sativa (Mill.) Thell) in the Semi-Arid Environments of Northwest India: Native Bees Are the Major Pollinators

Ecologies, 2023
Several insect species visit the flowers of a plant to obtain floral rewards in the form of pollen and/or nectar. In return, we would anticipate that those visitors would contribute to the reproductive success of the plant.

Exotic insect pollinators and native pollination systems

Plant Ecology, 2021
Insect pollinators have been relocated by humans for millennia and are, thus, among the world’s earliest intentional exotic introductions. The introduction of managed bees for crop pollination services remains, to this day, a common and growing practice worldwide and the number of different bee species that are used commercially is increasing.
