It is significant that on the cover of today's Unep report on global honeybee colony disorders is a photo of a honeybee with a varroa mite clearly visible on her thorax.
We started out by quantifying global and colony-specific parameters (e.g. size, shape and internal structure) as functions of time in order to morphologically characterize mESC development in different conditions promoting self-renewal.
But Britain's politicians - and its Foreign Office - have found it hard to adjust to the loss, not so much of onetime colonies, as of the global clout the colonies once afforded.
The impact of the parasitic mite Varroa destructor is certainly a major factor behind the global increase in colony failure rates [11], [12], [13], [14], but other stressors include various bee diseases (but especially Nosema sp. [15]), changes in bee management practice [16], factors related to climate change and seasonal shifts [17] and pesticide exposure [10], [12], [18], [19], [20].
For years, many of his peers in the Manhattan museum world have contended that the Guggenheim operation was a house of cards, a global empire with colonies in Venice, Bilbao, Berlin and most recently Las Vegas that is fatally addicted to new streams of revenue to cover old debts and risky gambles.
And then, we propose E-β-ocimene as a "non-specific worker castes signal" with a global action on the colony: increasing food provision.
That is, the larger the bimodal range, the less precise the switch is in order to generate a global response in the colony.
On the other hand, within the bimodality range, the response is distributed between two subpopulations, thus failing to achieve a global coordination in the colony.
As a result, we have revealed that the interplay between non-stationary and stochastic effects is key for understanding the global response of the colony and the phenotypic variability.
