Dr. Renée Marchin (Prokopavicius) is a plant ecophysiologist who studies the effects of warming and drought on plant function. She joined Hawkesbury Institute for the Environment (HIE) in August 2017 and is currently working on an ARC DECRA project entitled, “Green or crispy: Which plants use transpiration to survive heatwaves?”. Her aim is to discover which plant species can survive heat and drought in urban areas by determining relevant functional traits that protect droughted plants from thermal damage.
Dr. Prokopavicius’ research aims to improve predictions of the effects of climate change on terrestrial and urban ecosystems. She primarily uses ecophysiological approaches to understand how plant traits determine which species or genotypes succeed in changing environments. Her research has focused on plant traits related to water relations and growth, such as photosynthesis, stomatal conductance, transpiration, and water use efficiency. She has worked in a diverse range of terrestrial ecosystems, from temperate forests to subalpine grasslands to agricultural cropping systems.
Much of Dr. Marchin’s research has direct relevance to land managers, conservation organisations, and the agriculture/horticulture industries. As a rangeland technician for the Bureau of Land Management (California, USA), she monitored the effectiveness of efforts to restore degraded aspen stands. Her Ph.D. research (North Carolina State University, 2013) examined how phenology and transpiration of temperate forests will be affected by future warming. She studied how climate change affects the carbon fluxes of mountain grasslands in the Snowy Mountains (NSW, Australia). Her research for the Which Plant Where? project determined the heat and drought tolerance of over 100 plant species to inform selection of tolerant plants for urban plantings throughout Australia.
