The study aimed to identify the relationship between pollen collection, nectar, and seasonal dynamics of brood bee colonies Ukrainian breed their active activity when changing period season. We compared collection nectar from honey plants garden, white acacia, sunflower. number bees bringing hive was recorded. work collect is associated with uterus lay eggs broods in hives. Bee increase flight ...

Nectar enables users of the MoinMoin collaborative wiki editing environment to conveniently create and view in-text annotations to wiki documents without disturbing the underlying document. It is designed to facilitate online collaboration for traditional classroom learning by allowing authors to lock documents for editing, but still solicit comments online. Nectar has an obvious and easy to le...

We describe a multi-agent model of a honeybee colony and show several applications of the model that simulate experiments that have been performed with real honeybees. Our special emphasis was on the decentralized, self-organized regulation of brood nursing, which we successfully simulated: We found that brood manipulations, food-deprivation experiments and colony-size manipulations can be expl...

Foraging specialization allows social insects to more efficiently exploit resources in their environment. Recent research on honeybees suggests that specialization on pollen or nectar among foragers is linked to reproductive physiology and sensory tuning (the Reproductive Ground-Plan Hypothesis; RGPH). However, our understanding of the underlying physiological relationships in non-Apis bees is ...

The genetic and developmental basis of many ecologically important floral traits (e.g., carotenoid pigmentation, corolla tube structure, nectar volume, pistil and stamen length) remains poorly understood. Here we analyze a chemically induced floral mutant of Mimulus lewisii through bulk segregant analysis and transgenic experiments and identify a MIXTA-like R2R3 MYB gene that controls nectar gu...
