The timing of many phenological events of plants and animals is driven by temperature and other climatic parameters but the phenological response to climate and weather varies considerable between organisms. Few long-term studies exist which monitor phenology at a range of trophic levels at the same site and therefore we often rely on proxies to determine the potential for mismatch and other changes to ecosystem dynamics to occur in response to climate change. Our ability to monitor plant phenology remotely, from satellites and cameras, for example, has greatly increased in recent years but we must also rely on in situ observations to track subtle differences between species in both the timing and duration of key phenophases which may contribute to the potential for carbon storage in mixed forest communities. Sources of useful phenology data and duration of the time-series are crucial for use in determining future responses of ecosystems to climate change.
The main focus of this session will be to determine the effectiveness of phenological and biometeorological data to determine potential changes in ecosystem dynamics in response to climate change. We invite presentations related to the following topics:

•Identifying usable long-term phenology data sets (plant, bird, insect, etc.) to explore potential for mismatch and other changes to ecosystem dynamics
•Role of citizen science in phenology networks and data collection
•Impact of extreme weather events on phenology of wildlife
•Use of phenology and biometeorology in conservation decision making
•Observing and recording phenology from in situ methods to remote sensing (satellites, phenocams, etc.)
•Use of future climate projections in phenology modelling
•Relationship between phenology and carbon flux across different ecosystems
