Seeking UBRP Students for Summer 2024 (and beyond?)
The Meredith Research Group is currently seeking an undergraduate student(s) from the 2024 UofA Undergraduate Biology Research Program. We will use a mass spectrometer and soil incubations to measure how abiotic and biotic soil factors changes with the addition of specific VOC with time. We expect to identify VOC-consuming microbes and try to elucidate how VOC stabilizes carbon in soils. Some of the questions that we will ask will be: i) How microbial communities changes in diversity and abundance with specific VOC addition? ii) Identify VOC- consuming microbes to identify consumption and production of VOCs. Over Summer 2024 (and potentially into Fall) the student will help with volatilome, metagenome, transcriptome,…

Microbial drivers of N2O emissions in the Biosphere 2 Tropical Rainforest
Post by Juliana Young The Rainforest at Biosphere 2 is a unique study system because it operates under very high temperatures and has adapted to the Arizona heat. In 2002, Dr. Joost van Haren studied nitrous oxide (N2O) flux in the Rainforest at Biosphere 2 and found that there is a high and low pulse zone of emissions of this gas under the condition of post-drought (van Haren et al., 2005). Our study builds from the foundations of this experiment. We are testing what could be responsible for the spatial difference in N2O gas fluxes. While there are many facets of the Rainforest to study, my interests and area of…

Carbon cycle tracers, an infographic
I’m happy to present an InfoGraphic on Carbon Cycle Tracers created by University of Arizona art students Melissa Yepiz and Luke Williams in Prof Karen Zimmerman’s course on infographics. Creating this infographic on complex scientific concepts was not an easy task, but Melissa and Luke did an incredible job. Through this collaboration they have provided me with an invaluable resource for sharing my research to a range of audiences (and in a much more aesthetically pleasing way than usual). I learned a lot in the process, including how to better explain my science and to get down to the fundamentals of the message I wanted to share. I was blown away by the talent…

Undergraduate Researcher Shersingh’s SURGE Experience
Congratulations to visiting undergraduate researcher Shersingh Joseph Tumber-Davila on completing and thriving in the demanding eight-week Summer Undergraduate Research in Geoscience and Engineering (SURGE) program! Shersingh came to the Welander lab with a strong background in environmental research (news article) from his home institution of the University of New Hampshire. SURGE is a competitive earth science research and graduate school preparation program, which is specifically designed to recruit students of diverse backgrounds from other universities across the country. I was amazed at the number of activities the program had for the students including GRE test preparation, faculty seminars, career and grad school panels, and field trips. This was all while performing graduate-level research including…

BioDesign course – bridging science and art
Biologist/architect team Tobi Lyn Schmidt and Mike Bogan created a course linking artists, designers, architects, and biologists from the California College of the Arts (CCA) and Stanford University. I served as a postdoc mentor to help inspire and guide the process of cross-hybridizing biology and design (some examples) with three really talented undergraduate CCA students: Leslie Greene, Sakurako Gibo, and David Lee. The students were first charged with creating designs to illustrate scientific concepts in my field of research. I challenged them think about the issue of scale with respect to the biogeochemical cycles I study. The processes I investigate occur over a wide range of spatial and temporal scales,…

Deepa attends AGU and blogs about her experience
The EAPS department website shares Deepa’s blog about her first the AGU experience. She writes, “Science, nature, life, emergence, and the universe have always inspired my art. And it is the unnecessary beauty of science that makes it deeply mysterious and so inviting to my mind… AGU was an incredible week of reconnecting with friends, advisors, professors, fellow researchers. It was also unexpectedly a way for me to connect a path to a foreseeable future where my two passions can be combined, perhaps even muddled, into an exciting career.”

ISME conference on “the power of the small”
Last week I attended ISME 14 (International Symposium on Microbial Ecology) in Copenhagen, Denmark. It was a delight to see the city – its juxtaposed giant modern, cool, sterile buildings surrounding the historic old city. More of a delight was unexpectedly running into friends from the MBL Microbial Diversity summer school (2010) and realizing they are now my colleagues. The conference itself was quite good. I appreciated the range of content from very big picture and abstract to focused experimental projects. One message I took away from the community was a sort of -omics backlash, or perhaps whiplash, to the idea that generating more and more -omics data is the…

Deepa receives Goetze Prize for Undergraduate Research
At the 2012 EAPS Student Awards Ceremony Deepa Rao received the Christopher Goetze Prize for Undergraduate Research for her thesis entitled : “Exploring the Microbe-mediated Soil H2 sink: A lab-based study of the physiology and related H2 consumption of isolates from the Harvard Forest LTER.” The award recognizes ” innovative experimental design, care in data collection, and sensitive application of results to research problems.” It has been a pleasure to supervise Deepa’s thesis research and her results will contribute to our research efforts to understand the mechanisms driving the soil sink for atmospheric H2. Professor Ron Prinn acts as the faculty advisor for both Deepa and I.
