Recent research in spring phenology

What makes plants put on leaves in the spring? Day of year Accumulated heat (eg, Growing degree days) Jan 1 Mar 1
28
What makes plants put on leaves in the spring? Day of year Accumulated heat (eg, Growing degree days) Species x Jan 1 Mar 1
29
What makes plants put on leaves in the spring? Day of year Accumulated heat (eg, Growing degree days) Species y Jan 1 Mar 1
31
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/
32
Findings: Leaf unfolding triggered more by daytime temps than nighttime temps Piao et al., Nature Climate Change
33
Importance: Can improve predictions of leaf- out Piao et al., Nature Climate Change
34
How can we determine the heat requirement for leaf-out for a particular species? Day of year Accumulated heat (eg, Growing degree days) Jan 1 Mar 1 ?
35
How are your observations used?
36
Fu et al., Global Change Biology
37
What about chill requirements? Fu et al., Global Change Biology
38
What about chill requirements? Fu et al., Global Change Biology It matters! Over period 1980-2013: Temps increased ~1.4ºC Heat requirement increased 50%
39
What about chill requirements? Fu et al., Global Change Biology It matters! Warmer winters could delay leaf-out in the spring
