Domesticated honeybees and wild bees are some of the most important beneficial insects for human and environmental health, but infectious diseases pose a serious risk to these pollinators, particularly following the emergence of the ectoparasitic mite Varroa destructor as a viral vector. The acquisition of this novel viral vector from the Asian honeybee Apis ceranae has fundamentally changed viral epidemiology in its new host,...

We developed an annual tree‐ring δ 18 O chronology from Larix sibirica in the eastern Tianshan Mountains of northwestern China. Climatic response revealed that tree‐ring δ 18 O was significantly positively correlated with the mean and maximum July–August temperatures, whereas the July precipitation and relative humidity were significantly negatively correlated with tree‐ring δ 18 O . The self‐calibrating Palmer drought severit...
