THE NEW YORK KNICKS

Just over a week left to apply for a 3yr postdoc with me at Lancaster @lancasterplantbio.bsky.social looking at Rubisco engineering in vitro and in vivo to improve plant #photosynthesis #plantscijobs wp.lancs.ac.uk/lancsphotosy...

Leaf drought and heat tolerance are integrated across three temperate biome types I am very happy to see our paper out! Plant responses to many stresses are mediated by the same processes and I have long wondered how this relates to hotter droughts. www.nature.com/articles/s41...

This post is now online, for full details on how to apply please see: wp.lancs.ac.uk/lancsphotosy...

Excited to share that I'll soon be recruiting a 3 year postdoc to join the lab @lancasterplantbio.bsky.social to work with me on Rubisco biochemistry and engineering. Official advertising details to be released very soon, watch this space! Please spread the word. 😀🌱🧪🥼

Fully funded PhD in Plant Ecophysiology at UBC in Vancouver 🍁! Possible topics include leaf physiology, thermal ecology, microclimates, scaling, tree physiology, forest ecology & more. Start Jan/May/Sept 2026. michaletzlab.org Please share! #PlantEcoPhys #Ecology #Botany #PhDposition #GradSchool

Has to be up there as one of my favourite saguaros in the valley 🌵 #arizona #cacti #botany

Need a Monday pick-me-up? Here's a throwback to 2022, when our field ecology program director Susan Bush had an extraordinary encounter with a huge band of coatimundis while working at our field site in Wet Beaver Creek, AZ How many can you spot?? #coati #ecology #fieldwork #arizona

Mapping the roots of saguaros at Saguaro NP. The DBG is partnering with SNP and the U of Wyoming to map the roots of saguaros. Knowing the distribution of saguaro roots reveals how sensitive they are to droughts, and to what extent these iconic plants engineer the water cycle of desert ecosystems.

Might listen to this saxophone solo on an endless loop today. Rest in Peace and eternal gratitude to Garth Hudson, an actual musical genius and the last surviving member of the Band. “Garth made us sound like we did.” youtu.be/Q7yOGAmItFY?...

David Lynch gave us the language we needed to better articulate the indescribable strangeness of our shared reality. “Lynchian” is so overused because it’s a viscerally understandable word without any known synonyms. I can’t imagine a more beautiful artistic legacy than that.

Excited to share our paper with Anna Gardner and @florianabusch.bsky.social in Plant Ecophysiology!🌿 We review challenges in interpreting plant stress responses using gas exchange data, offer solutions to improve accuracy and discuss gaps in our current knowledge. www.sciltp.com/journals/Pla...

Enjoyed chatting about our recent work on leaf cooling during extreme heat! If the clip has you curious, you can find the paper here www.pnas.org/doi/10.1073/...

Just out! By using high-thru-put phenotyping, we show that 60% of variation in wheat leaf respiration is under environmental control, with upto 1/3 of variance under genetic control. Super proud of Reshmi and team. @jxbotany.bsky.social @anuagrifood.bsky.social academic.oup.com/jxb/advance-...

For folks attending #AGU24, our lab has its 1st conference poster presentation led by PhD student Rebecca Senft! @RebeccaSenft Stop by her poster on the morning of Tues Dec10 to learn about the ecohydrology of contrasting riparian tree species (invasive vs native) in SE Utah. #ecophys #invasion

They say when life gives you lemons, make lemonade 🍋 Well when Phoenix gives you record heat, you study plant heat tolerance! This summer we used the natural heat to get our greenhouse up beyond 50°C (!) and studied how 8 dryland species responded - stay tuned for results! #Botany #PlantScience 🧪

Plant respiration alert! Important new review by Amthor in Field Crops Research. Key take homes: 30-60 % of Cassimilated in photosynthesis is later respired; opp to improve yield by reducing nonessential respiration; respiration a target for crop improvement. www.sciencedirect.com/science/arti...

🚨 Paid research experience for undergrads! 🚨

 Apply now for undergrad research summer program in Dr. Luiza Aparecido’s plant ecophys lab @ U of Utah, studying plant heat tolerance across Utah (May 19-Aug 1, 2025) For more info contact [email protected]

Welcome to our newest lab arrivals - 20 young saguaro #cacti!   We're planting these saguaros in our #cactus common garden here at the Desert Botanical Garden, where they will help us study the response of cacti to changing soil water availability 🌵💧 #Botany #PlantScience 🌾🧪🌎

A new friend joined us outside for lunch today here at the Desert Botanical Garden - ground squirrels beware 👀 🐍

Our new paper finds direct cooling effects of winter cover cropping from increased albedo and latent heat flux The paper was led by former Masters student Risa McNellis and is out today. Check it out! esajournals.onlinelibrary.wiley.com/doi/full/10....

Stomata respond to temperature, even if VPD is held constant. This is ALL published data! (AFAIK) (Not my data - too many sources to reference, but watch this space.) Close to submission on this review, which is already two weeks overdue. Looks like I picked the wrong week to quit amphetamines.
