PhD from Hawkesbury Institute for the Environment, WSU🌿Plant physiology. Tree responses to climate change

Joined June 2018
My Corymbia calophylla common garden G x E study is out. We measured physiology, functional and growth traits in 10 populations over two seasons at 2 plantation sites. https://t.co/IAud3BHyp6

I'm enjoying all of the flowering marris around Perth and the flowers smell so good. But I wonder whether the prolific flowering is a stress response. Perth has had one of its hottest summers on record #corymbiacalophylla #risingtemperature #eucalypt #climatechange?

Our recent work on tree dieback associated with drought and heatwaves discussed in a recent Guardian article #treedieback #planthydraulics #climatechange #globalchangetypedrought #drought #heatwaves

Even species ‘superbly adapted’ for Australia’s harsh conditions suffered, with up to 60% of trees dying in some areas

Abstract. The viability of forest trees, in response to climate change-associated drought, will depend on their capacity to survive through genetic adaptat

Some colleagues and I have just published a fun paper exploring plasticity to repeated heatwaves under different temperatures. FFO thermal tolerance and safety margins. @DNAprymer @AndyPlantLady @anthea_challis @AdrienneNicotra @Margare77278174

Our recent paper led by @M_EsperonR shows plasticity in important drought tolerance traits such as TLP (wilting point, shown. Tristaniopsis laurina) in an urban city in four tree species grown across a #rainfall and #temperature gradient. https://t.co/v2EkgbSuaY

Exciting technique for measuring leaf temperatures during photosynthesis using oxygen #isotopes discussed at #AGU19 by Sean Michaletz #plantphys (note this temperature image is of a canopy using a different technique)

If you're interested in the adaptive capacity of plant drought traits and how we can use them to predict drought associated tree mortality come to my talk today in the tree mortality symposium at #AGU19 room 3003 L3 Moscone west from 10:20

Ready to play #AGU19 bingo. Kudos to @krdorheim for her excellent work! I got lucky w/ my card, as “someone who goes over and the red light is blinking” is basically the same as “Free Space” right

Findings by William Anderegg reveal maximum photosynthetic capacity and hydraulic traits are important in influencing soil moisture feedbacks and greater diversity of hydraulic traits contributes to greater drought resilience globally #AGU2019 #plantphysiology #climatechange

We are noticing a trend involving instrumentation and baked goods. We approve entirely.
