Message from the Associate Vice-President and Director of Extension


I hope everyone had an enjoyable break and took some time to decompress over the holidays. The last we left, a hiring freeze was imposed, and a new budgeting process was implemented. I can only tell you what I know and what we are doing to help update everyone on where Extension stands.

I know we are part of the hiring freeze, and all Extension state-funded positions are frozen. Details can be found in the January 3 email from senior leadership here. I know we have a few positions where verbal or written offers were extended but not signed, and they, too, are frozen. That’s what we know.

What are we doing? We are working with ALVSCE leadership to request that Extension be removed from the current hiring freeze. This is a team effort, as we contend that Extension should have never been part of the freeze since we have a separate state budget line and we need to move forward with our hires to meet our mission. As for travel, please continue to travel as needed. I am confident that Extension professionals are always thrifty in spending on food, travel, and meetings – I ask that you continue to be. I understand how frustrating this is for many of you, and I assure you we are doing what we can to get the hiring process in Extension moving forward again.

I ask for patience, even though I know we don’t have time; I ask for understanding, even though we don’t have all the answers; and I ask for your support and confidence that the state Extension office and ALVSCE are doing their best to continue our support of our staff, faculty, and stakeholders throughout the state. Circumstances can change quickly, and I will send out any changes as soon as I have confirmation.


Workshop: Demystifying APIs for Researchers


A wide variety of data shared on the web (including spatial data, census data, 'omics data, bibliometric data, and more!) are available through some web API ("Application Programming Interface").  In this workshop you'll learn what an API is, how to access data using APIs, and how to write R code to automate downloading data from APIs using the httr2 package.

When: 11 a.m., January 24
For more information and to register, please see the workshop website.


Bayesian Learning Group

In this peer-to-peer learning collaborative, we will work through foundational concepts in Bayesian statistics scaffolded around Richard McElreath’s Statistical Rethinking, 2nd edition textbook and video lectures. Our meetings will be split between book-club-style discussions and working through statistical examples in R and Stan. Familiarity with R and the foundations of probability will be extremely helpful.

When: Noon-2 p.m., every other Friday beginning January 19
For more information and to register, please see the learning group website.

For more information about the CCT-Data Science team and our offerings, including workshops, drop-in hours, our Data Science Incubator program, and our work collaborating on funded projects, please see our website.

Shantz Building

Emergency Walkthough


During this virtual walkthrough, Tait Hansen, Ryan Daily, and Jeff Ratje will prepare you to locate Automated External Defibrillators (AED’s) and fire extinguishers, find and identify emergency exits on each floor, access the Shantz Building emergency plan – before you are in an emergency.

When: 3-3:30 p.m., Wednesday, January 10
Where: Zoom at https://arizona.zoom.us/j/988216542

Understanding Plant Names
Michael Chamberland

Having the correct name for a plant is important. A name is key to finding information about a plant from the internet or reference books. Is the plant native to Arizona? Is it toxic? Can it withstand freezing? How big can it grow?

Measurements of carbon dioxide (CO2) emissions from agricultural soils are essential to understand the journey of an agricultural operation toward sustainability. Existing commercial technologies to measure CO2 emissions are expensive and require advanced technical knowledge. A new, low-cost, in-situ CO2-measuring device was designed and standardized by the authors to upscale CO2 emission measurements in commercial agricultural operations, spatially and temporally. We present an initial report from our preliminary studies as we measured CO2 emissions in different agroecosystems and compared different management strategies. Diurnal soil respiration or CO2 emission was also measured under different weather conditions. We coined the term, Potential Soil Respiration or PSR, to indicate the CO2 emission from soils with actively growing crops. Our data revealed that cover cropping influenced carbon storage in the soil while fallowing continued to lose soil carbon in a cotton production system, which was correlated with plant vigor. We are also working toward integrating this sensory system with other existing or new sensory systems to be deployed in commercial agricultural operations for effective natural resource management and environmental stewardship.
