Highlights•Bees' specific nutritional requirements are partitioned between pollen and
nectar.•Nectar and pollen provide carbohydrates, protein, lipids, and micronutrients.•Bee …

As global surface temperatures rise, global precipitation rates are predicted to increase.
These localised increases in rainfall patterns may significantly affect plant–pollinator …

Bumblebees are familiar and charismatic insects, occurring throughout much of the world.
They are increasingly being used as a model organism for studying a wide range of …

Bees are herbivorous insects, consuming nectar and pollen throughout their life cycles. This
paper is a brief review of the chemistry of these two floral resources and the implications for …

Nectar properties tend to be similar for plants visited by the same kinds of pollinators, and
much of the available information on nectar chemistry has been collected in the context of …

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the
female parts of flowers for plant reproduction-are an essential part of natural and agricultural …

On the average, nectar-collecting bumble bees deposited 0.6% of the pollen removed from
the flowers of Erythronium grandiflorum (Liliaceae) onto the stigmas of subsequently visited …

Alterations in water availability and drought events as predicted by climate change
scenarios will increasingly impact natural communities with effects already emerging at …

To investigate whether floral resource quality impacts on bumble bee floral choices, we
determined the pollen foraging constancy and floral choices of four bumble bee species …

Bumblebee workers vary greatly in size, unlike workers of most other social bees. This
variability has not been adequately explained. In many social insects, size variation is …
