Worker bees provide another example of the use of marginal value theorem in modeling optimal foraging behavior. Bees forage from flower to flower collecting nectar to carry back to the hive. While this situation is similar to that of the starlings, both the constraints and currency are actually different for the bees.
The genes associated with foraging behavior have been widely studied in honeybees with reference to the following; onset of foraging behavior, task division between foragers and workers, and bias in foraging for either pollen or nectar. [5] [8] Honey bee
Foraging at extreme distances wears out the wings of individual bees, reduces the life expectancy of foraging bees and therefore the efficiency of the colony. The minimum temperature for active honeybee foraging is approximately 55 °F (13 °C). Full foraging activity is not achieved until the temperature rises to 66 °F (19 °C).
To resolve the issue and maximize both their total consumption during foraging, bumblebees forage early in the morning, while honey bees forage during the afternoon. [96] A 2017 systematic review looked at the impacts of managed bees on wild bee populations. In addition to honey bees, this includes bumble bees and some solitary bees.
Bees learned the fastest when violet light was rewarded, and the slowest when the light was green; the other colors fell somewhere in between. This evidence of inherent bias is evolutionarily reasonable, given that bees forage for differently-colored nectar-bearing flowers, many of which are to be found in green foliage which does not signal ...
Bees that follow a waggle dance can successfully forage without decoding the dance language information in several ways: [4] Dance follower may use olfactory information from the dancer and find either the same resource or a different one with a similar scent. Following a dance may simply trigger foraging behavior.
[1] [2] [3] This type of foraging behavior puts selective pressures on floral traits in a process called pollinator-mediated selection. Flower constancy is different from other types of insect specialization such as innate preferences for certain colors or flower types, or the tendency of pollinators to visit the most rewarding and abundant ...
For example, when constructing an optimality model for bee foraging time, researchers looked at whether energetic efficiency (energy gained/energy spent) or net rate of gain ((energy gained − energy spent)/time) was optimized. It was found that the bees maximized energetic efficiency when foraging for nectar. [4]
