I have released my most powerful & high-yielding corn yet. It has already escaped my field & invaded three soybean farms. I fear it will soon kill all humans. But rather than quit corn & work to stop the apocalypse, I'm releasing even better corn in 3 months. Meanwhile, please use corn responsibly.

Hey folks I am recruiting for a phd position in tree thermal physiology. 🌐🌾🧪 Ad below. Applications due Dec. 1st www.unlv.edu/graduatecoll...
1)	PhD in tree thermal physiology to investigate the impacts of heat extremes on tree performance and survival. The PhD student would pursue independent research to identify the thermal limits to tree survival in natural forests and urban canopies. A major focus of the position is on studies using thermal cameras, field sampling of plant stress through metrics like water potential, and monitoring of tree mortality. The student would also have the opportunity to develop their own research questions and participate in the Southwest Climate Adaptation Center (SWCASC, https://www.swcasc.arizona.edu/about/overview).

Required qualifications: 
•	BS or MS in a related field (env sci, ecology, statistics, forestry, biology, etc.)
•	Some knowledge of plant physiology
Preferred qualifications:
•	Comfortable working in R
•	Ecophys experience (e.g., water potential, gas exchange)
•	Experience with thermal imagery
•	Scientific writing experience

Applications due Dec. 1st through UNLV Graduate College:
https://www.unlv.edu/graduatecollege/apply Candidates can email Drew.Peltier@unlv.edu describing their interests in the position and relevant experience, including a CV. However: I am unable to assess candidate suitability before students have formally applied through the UNLV Graduate College.
