As of 2020, 56% of the world’s population live in urban areas. These individuals benefit from numerous ecosystem services provided by urban forests, including urban heat island mitigation, energy use reduction, stormwater interception, wildlife and pollinator habitat provision, air pollution removal, and carbon sequestration. Urban greenspaces are also often the most accessible avenue for exposure to the natural environment, providing additional aesthetic, recreati...

Symposium 5

Urban trees provide important environmental services and are indispensable for the regulation of a city's climate, whilst growing in stressful conditions with low water and space availability. However, compared to their forest counterparts, little is known about urban trees' capability to cope with climate change. Due to the heat island effect, Montreal has already experienced 1.4°C higher temperatures, creating increasingly challenging conditions for urban trees. Planting resilient trees ...

Symposium 3Dendrogeochemistry

Stable carbon (δ13Cc) and oxygen (δ18Oc) isotopes in tree-ring cellulose, and tree-ring width (TRW), have been used extensively to investigate the effects of climate on tree growth. By contrast, the information recorded by the non-exchangeable carbon-bound hydrogen (δ2Hc) isotopes, has been far less explored. To create a comprehensive assessment of δ2H potential as a proxy for climate, hydrology, plant metabolism, and physiology we explored its relationships with climate an...

Time Zone: (GMT-05:00) Eastern Time (US & Canada)
8:30 - 12:30 | 4 hours

MAIDENiso is a numerical process-based model that allows researchers to simulate the growth of a virtual tree. Using daily meteorological data, the model simulates the physical and physiological processes taking place in the tree and its environment, to produce daily and yearly outputs comparable to dendrological observations. The model has been adapted and used successfully in boreal regions in North America. In an inverse mode, tree-ring obs...

13:30 - 17:30 | 4 hours

Free, in person and onlineWe will hold a practical, skills-based workshop introducing openDendro -- an open-source framework of the base analytic software tools used in dendrochronology in both the R and Python programming languages. openDendro is a new unified set of tree-ring analysis tools in open-source environments that provides the necessary baseline for dendro...

13:30 - 17:00 | 3 hours 30 minutes

Free, in person and onlineThe stable isotopic compositions of carbon and oxygen (d13C and d18O) measured in tree rings are valuable proxies for reconstructing paleoclimate and are increasingly used as paleophysiological proxies. Applying these proxies in ecophysiology and paleoclimate can be challenging as they rely on complex process-based models and poorly constrained input data. In recent years, h...

Symposium 1

Tree-ring time series provide long-term, annually resolved information on the growth of individual trees. However, public tree-ring archives contain a considerable portion of data collected from trees that have been selected with specific research questions in mind (e.g., for climate reconstruction).  This makes these archives a biased representation of the sensitivity of forest ecosystems to ongoing climate variation (e.g. temperature, precipitation), including non-stationarity (i.e....

The interpretation of stable isotopes in a dendroecological framework can provide powerful insights into how trees adjust physiologically in response to the environment. This symposium aims to bring together researchers who use stable isotopes in tree rings to address ecophysiological responses to environmental changes from intra-annual to multi-decadal resolution. We hope this symposium will enable fruitful discussions and new ideas a...
