The lack of appropriate nesting habitat and dominance of exotic flowering plants in residential neighbourhoods appeared to positively impact upon the generalist A. mellifera, but negatively affected cavity and ground nesting floral specialist bee species (e.g. Halictidae and Colletidae).
Many North and Central American species are visited by specialist bee pollinators, but other insects with more general feeding habits such as honey bees also visit.
Wilson et al. (2010) successfully used the internal transcribed spacer (ITS), as well as other ribosomal sequences, as a genetic barcode to identify monospecific pollen collected by a specialist bee.
Beyond food and nesting sites, cities offer escape from many agricultural pesticides, and even reduced herbivory pressure on rare host plants some specialist bees can't live without.
An answer to this hypothesis may be found by comparing closely related species with different ecology, e.g. generalist vs. specialist bees (Burger et al., 2013).
Courtesy of the Daily Mail, whose sternest vigilantes are now repeatedly knocked out by Camilla's hair/dresses/skin tone, her ever-increasing plasticity and glossiness can be authoritatively attributed to yoga, pilates, bigger hair, highlights, a travelling hairdresser, gowns by Bruce Oldfield and, even, channelling Diana, her own "guru", a specialist in bee-venom facials.
Most hives have 15,000 to 60,000 bees, said Prof. Jamie Ellis, a bee specialist at the University of Florida.
This specialized process requires beekeepers and bee specialists to transport tens of thousands of bees to farms – in this instance Rodney Oakley moved 30,000 bees, the amount typically found in a small hive, in Austin, Texas.
Theis et al. (2014), for example, found that floral sesquiterpenoids from Cucurbitaceae were the best predictors of flower preference for both the specialist pollinator squash bees and the specialist herbivore cucumber beetle.
