The Urban Trees Ecophysiology Network

As an urban plant ecophysiologist I'm interested in how the vegetation in urban systems interacts with the local microclimate. In particular, I study the mechanisms by which trees cope with extreme urban heat, and how their presence modulates the urban climate through transpiration cooling, shading and more. For my research, I combine mostly tree-level measurements, such as gas exchange and heat tolerance, with process-based modelling to scale to the urban canyon and beyond. I'm interested in comparing the acclimation of different species to contrasting environments in cities across climates to better understand underlying life-history traits and their plasticity, and thereby estimate the potential of urban trees for improving the urban microclimate.

Studies the tree's response to heat waves, on multiple time scales. Develops advanced time series analysis tools and models to reveal hidden patterns in tree resilience. Developed the Trumpet IoT datalogger for UTEN. Plays the Trumpet, of course, as a professional jazz musician. Nepenthes aficionado.

Professor, Département des sciences biologiques, Université du Québec à Montréal (UQAM) Chair in urban forestry I am interested in green infrastructures and the effects of biodiversity on the functioning and resilience of forest ecosystems, both in the forest and in the city. My current research makes use of controlled experiments, simulations and long term field surveys to test the links between biodiversity and ecosystem functioning in forest ecosystems. I am scientific coordinator of the International Diversity Experiment Network with Trees (IDENT), with several experiments established in North America, Africa and Europe. I also lead a research chair on the urban forest.

Post-doctoral researcher at the University of Helsinki, Finland. My work focuses on how trees function and acclimate in differing urban environmental conditions, with a particular interest in the emissions of volatile organic compounds (VOC) by urban trees.

I am Associate Professor of Plant Physiological Ecology at the University of the Witwatersrand in Johannesburg, South Africa. My research examines the evolved physiological mechanisms underpinning ecological patterns and processes, particularly those arising in response to abiotic stresses. I pursue this by combining trait measurements with natural experiments conducted at scales ranging from whole plants to entire ecosystems and in natural, agricultural and urban environments.

Xue’s group research aims to advance process understanding and representation of ecohydrological processes. We also apply this knowledge to improve carbon and hydrological predictions at the ecosystem and watershed scales. For UTEN, we are using remote sensing and machine learning methods in combination with field data to inform the magnitude and geographical extent of canopy water stress and its correlation with cooling benefits. feng.umn.edu

A plant ecophysiologist whose PhD focused on unravelling the main physiological processes driving drought-induced tree mortality. Particularly interested in how, under extreme water stress, a decrease in plant’s relative water content, subsequent to the failure of plant’s vascular system, lead to cell death and particularly meristem death.
