Ecohydrology Research Group Members Co-Author Paper in Nature Scientific Reports
December 2021
A paper coauthored by Ecohydrology Research Group members Eunji Byun, Fereidoun Rezanezhad, Linden Fairbairn, Steph Slowinski, and Philippe Van Cappellen was published in Nature Scientific Reports on December 1st! The study examines the effect of temperature, moisture, and freeze-thaw regimes on CO2 production from northern peatland soils. The authors analyzed the impact of these parameters on CO2 production using laboratory incubation and kinetic modelling.

Study co-authored by ERG researcher featured in WaterResearch
A study co-authored by Fereidoun Rezanezhad was recently featured in WaterResearch, a communication that summarizes high impact scientific articles published by researchers of the Water Institute. The paper, titled “Winter CO2 losses shift the Arctic to a carbon source under current and future climates,” was originally published in Nature Climate Change. The major finding of the study was that respiration during the non-growing season (NGS) represents a substantial component of the Arctic’s carbon balance, and that warming during the NGS has increased CO2 losses, shifting the Arctic to a carbon source rather than a sink.

AGU Fall Meeting 2019
December 2019
Fereidoun and Konrad, along with several Ecohydrology group members, attended the AGU Fall 2019 meeting this past December. Fereidoun cochaired "Ecology of the Cryosphere: Biological and Environmental Interactions in Seasonally and Permanently Cold Ecosystems," which included researchers presenting topics ranging from carbon uptake and loss in northern temperate ecosystems to exploring benthic microbial communities in ice-covered Antarctic lakes as analogues for life on early Earth! Both Fereidoun and Konrad presented posters as part of this session.
New paper on winter carbon losses co-authored by ERG researcher published in Nature Climate Change
November 2019
Ecohydrology group researcher Dr. Fereidoun Rezanezhad has co-authored a new paper on winter CO2 losses from northern permafrost regions which was published today in Nature Climate Change. The study, supported by NASA ABoVE and in collaboration with over 50 institutions and the Permafrost Carbon Network, demonstrated that winter soil CO2 loss will increase 41% by 2100 with warming temperatures under a business-as-usual emissions scenario. The authors also warn that increases in CO2 loss under winter warming may outweigh any enhanced uptake of carbon during the growing season. This study provides new insights into permafrost winter carbon budgets which will be useful for improving global models and informing climate policies.
Dr. Fereidoun Rezanezhad awarded highly competitive NSERC funding on winter carbon losses in wetland ecosystems
Dr. Fereidoun Rezanezhad is leading one of nine projects to have awarded funding under the highly competitive “Advancing Climate Change Science in Canada” initiative. Find out more about the project and award here.
