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 …

Bumble bees play a vital role in the pollination of many crops and wild flowers, and plans for
their conservation require a knowledge of the dynamics and spatial scale of their foraging …

Morphologically complex flowers are characterized by bilateral symmetry, tube-like shapes,
deep corolla tubes, fused petals, and/or poricidal anthers, all of which constrain the access …

The majority of species of flowering plants rely on pollination by insects, so that their
reproductive success and in part their population structure are determined by insect …

Sleep affects learning and development in humans and other animals, but the role of sleep
in developmental learning has never been examined. Here we show the effects of night …

Bees make choices about what flowers to visit among the options in the floral market. Bee
specialization to visit only one plant species at a time is relevant to maintain the plant-bee …

Bees collect food from flowers that differ in morphology, color, and scent. Nectar‐seeking
foragers can rapidly associate a flower's cues with its profitability, measured as caloric value …

We compared pollen removal and deposition by hummingbirds and bumblebees visiting
bird‐syndrome Penstemon barbatus and bee‐syndrome P. strictus flowers. One model for …

An activity pattern is the change in levels of a particular activity through time. Activity pattern
data form the basis of much of behavioral ecology for two simple reasons. First, they tell us …

Multimodal signals are common in nature and have recently attracted considerable
attention. Despite this interest, their function is not well understood. We test the hypothesis …
