First Day

Today is the first official day of my postdoc position at CLEX. As I await examination of my thesis, I get to moonlight as a Postdoctoral Research Associate despite being more Middoctoral. Gab remains my supervisor, I am still based in the Climate Change Research Centre at UNSW Sydney, and in fact I keep my desk from the PhD. To jolt the mindset from ‘student’ to ‘employee’, I took six weeks off after thesis submission (9th August) to hike in Western Australia. While hiking alone, I reasoned that I should aim to improve this website among many other revelations. Therefore, the blog section returns. Let’s see how it goes!

Resurrecting the website. I’m not even going to attempt to re-engage with the unholy mess of my previous attempt. Templates exist for a reason, so this time I’ve let other people do the hard work. I’m more than happy to reap their rewards.

Examining the role of environmental memory in the predictability of carbon and water fluxes across Australian ecosystems

Published in Biogeosciences, 2022

Although vegetation responds to climate at a wide range of timescales, models of the land carbon sink often ignore responses that do not occur instantly. In this study, we explore the timescales at which Australian ecosystems respond to climate. We identified that carbon and water fluxes can be modelled more accurately if we include environmental drivers from up to a year in the past. The importance of antecedent conditions is related to ecosystem aridity but is also influenced by other factors.

Non-Stationary Lags and Legacies in Ecosystem Flux Response to Antecedent Rainfall

Published in JGR: Biogeosciences, 2023

To predict how changes in future climate and weather extremes might impact terrestrial ecosystems, we need to understand the timescales of vegetation response to antecedent climate. Prevailing methods of exploration assume such responses to be stationary, that is constant through time. We present a novel approach that shows how the memory of plants to climate conditions change through time. We show that the carbon and water fluxes of vegetation can be significantly sensitive to antecedent rainfall and importantly that this sensitivity can vary substantially through time. Plant functional type is a key indicator of the role of memory to precipitation, while the response to antecedent rainfall is not determined by site aridity. Predicting future changes in the global carbon sink requires understanding how vegetation responds to climate across timescales. Identifying these timescales at which plants respond to climate is critically important as the climate changes, especially if extremes (e.g., heatwaves) become more frequent due to compounding effects.
