• Phenology is changing rapidly
• This affects species distributions, abundance, interactions, and more
• Monitoring will inform adaptive refuge management

Does it matter whether the warmth happens during the day or night?
Piao et al., Nature Climate Change
https://www.climatecommunication.org/new/features/heat-waves-and-climate-change/heat-waves-the-details/
Findings:
Leaf unfolding triggered more by daytime temps than nighttime temps
Piao et al., Nature Climate Change
Importance:
Can improve predictions of leaf-out
Piao et al., Nature Climate Change
How can we determine the heat requirement for leaf-out for a particular species?

What about chill requirements?
Fu et al., Global Change Biology
It matters!
Over period 1980-2013:• Temps increased ~1.4ºC• Heat requirement
increased 50%
What about chill requirements?

It matters!
Warmer winters could delay leaf-out in the spring
