In PLB style (but with a URL) ....

> There are concerns that species-specific shifts in phenology in response to climate warming may lead to temporal mismatches between interacting species.

> Trap-nests were colonized by a variety of solitary, flower-visiting Hymenoptera—mainly megachilid bees, eumenine wasps, and their predators.

> In general, degree-days above 10 degrees Celsius was the best predictor of insect emergence; for plants, degree-days above 0 Celsius was usually the best predictor. These results suggest that emergence time is highly plastic in these insects and depends on similar—but not identical—cues to those regulating flowering time in the local plant community.

> ... indicating that some decoupling between plants and pollinators is possible. However, the use of similar temperature cues and generalist habits should make plants and pollinators in these habitats resilient to phenological changes driven by climate warming. 

Jessica Forrest and James D. Thomson: 'Will climate change disrupt synchrony between subalpine plants and pollinators?'

Or, in Juanse's style:

- midi experiment to look at timing of plants and pollinators
- in the Rockies
- insects emerge around the right time to exploit their forage
- pretty much driven by temperature
- in the Rockies


And me:

- you can muck about with the planet's climate to a certain extent and get away with it, as between-year variation is already high and some of the planet's life is adaptable 
- best not go too far though (in some ways it is nice to see the UK's and parts of mainland Europe's carbon footprint dropping for a day or two)

best wishes
