Wild pollinators are in decline, and managed honeybees cannot compensate for their loss. [Also see Reports by Garibaldi et al. and Burkle et al.] Three-quarters of global food crops depend at least partly on pollination by animals, usually insects (1). These crops form an increasing fraction of global food demand (2). Given this importance, widespread declines in pollinator diversity (3) have led to concern about a global “pollination crisis” (4). However, others have argued that this concern… 
Management of Pollination Services to Enhance Crop Productivity
The technology of using managed pollinators to overcome pollination constraints is yet to be exploited in developing countries, largely due to lack of awareness amongst the farmers, insufficient data on crop pollinators and limitation of research backup on the management of pollination services.
Importance, Drivers And Conservation Of Wild Bees For Apple Pollination
The calculation of “Pollinator importance”, as the product of pollinator effectiveness and relative abundance, provided a framework to experimentally quantify the contribution of native bees to apple yield and quality and translated per-visit pollen deposition to fruit and seed set by experimentally developing functional relationships between pollen deposition and these measures of reproductive success.
Disentangling multiple drivers of pollination in a landscape-scale experiment
It proved to be important to disentangle habitat isolation from habitat loss, local from landscape-scale effects, and direct effects of pollen availability on fruit set from indirect effects via pollinator visitation to understand the delivery of an agriculturally important ecosystem service.
How many species of arthropods visit flowers?

  • 2015
An overview of the taxonomic range of flower-visiting invertebrates is presented and it is speculated, based on reviewing the literature and discussions with experts, that ~30 % of arthropod species may regularly utilise flowers to feed, find a mate, or acquire other resources.
Pollinator declines: reconciling scales and implications for ecosystem services
It is shown that bee species that are currently delivering most of the ecosystem services (i.e. crop pollination) are not among the species showing declining trends, but rather appear to thrive in human-dominated landscapes.
Causes and consequences of variation in the nutrition and endemic microflora of food stores in managed honey bees (Apis mellifera L.)
The results showed that dietary protein and carbohydrate is significantly correlated with the overall fitness of a hive in terms of expression a constituent immune response, and indicate that a more diverse diet of plants will benefit honey bees by increasing their dietary protein intake.
Ecology of native bees in North Taranaki, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology at Massey University, Manawatū, New Zealand
Studies are increasingly finding that native bees are important pollinators in many systems, in both natural and agricultural settings. With the possible loss of honey bees due to various reasons, it
Road mortality potentially responsible for billions of pollinating insect deaths annually
Evidence is presented for a generally understudied yet potentially significant source of pollinator mortality, collisions with vehicles, and the need for research to assess whether the mortality levels observed are contributing to the substantial declines of pollinating insects occurring on a global scale, thus putting the ecological functioning of natural areas and agricultural productivity in jeopardy.

Holistic Management of Pollinators and Pests: Integrating Semiochemicals With On-Farm Pesticides
Abstract Insect pollinators and insect herbivores affect plant reproduction and fitness. Floral displays are used to attract and manipulate pollinators' behavior to support plant sexual reproduction


Plant-Pollinator Interactions over 120 Years: Loss of Species, Co-Occurrence, and Function
Using historic data sets, the degree to which global change over 120 years disrupted plant-pollinator interactions in a temperate forest understory community in Illinois, USA is quantified and it is suggested that networks will be less resilient to future changes.
Wild Pollinators Enhance Fruit Set of Crops Regardless of Honey Bee Abundance
Overall, wild insects pollinated crops more effectively; an increase in wild insect visitation enhanced fruit set by twice as much as an equivalent increase in honey bee visitation.
Importance of pollinators in changing landscapes for world crops
It is found that fruit, vegetable or seed production from 87 of the leading global food crops is dependent upon animal pollination, while 28 crops do not rely upon animalPollination, however, global production volumes give a contrasting perspective.
Report Warns of Looming Pollination Crisis in North America
Honeybees are in trouble, according to a report on North American pollinators unveiled this week by a committee of the National Research Council. The committee calls for better long-term monitoring
Reconciling Food Production and Biodiversity Conservation: Land Sharing and Land Sparing Compared
Compared crop yields and densities of bird and tree species across gradients of agricultural intensity in southwest Ghana and northern India, land sparing is a more promising strategy for minimizing negative impacts of food production, at both current and anticipated future levels of production.
Temporal dynamics in a pollination network.
The day-to-day dynamics of an arctic pollination interaction network over two consecutive seasons are studied and temporal dynamics provides a mechanistic explanation for previously reported network patterns such as the heterogeneous distribution of number of interactions across species.
