A/Prof Catriona Macdonald joined the Hawkesbury Institute for the Environment in November 2010 investigating the impacts of environmental change on nutrient cycling and resource allocation within terrestrial environments. Her research interests are geared towards understanding how environmental change impacts nutrient cycling and ecosystem functioning and how this affects productivity and sustainability of soils.
Working across natural, agricultural and managed ecosystems, she aims to improve understanding of how factors such as climate change and land management impact microbial-mediated nutrient transformations, and how this feeds back to ecosystem functioning.
To achieve this Catriona uses field-based and controlled environment studies to determine rates of nutrient (C, N and P) transformations, quantify nutrient resource allocation in above- and below-ground pools, as well as investigating the function and diversity of key microbial drivers in C N and P cycles using a range of in-situ approaches (soil CO2 flux, decomposition, net mineralisation), laboratory assays (MicroResp, enzyme activities, potential mineralisation, degradation rates) and molecular approaches (community profiling and sequencing analysis).
Her research experience includes determining the effects of elevated CO2, elevated temperature, drought and atmospheric N deposition, on nutrient cycling and on the functioning and structure and of soil microbial communities, as well as assessing the sustainability of long-term metal contaminated sludge addition in agricultural systems.
Catriona also maintains an interest in the application of microbial profiling techniques for forensic use in both environmental and human biomes.
