Chance will have the opportunity to travel to Toledo, Ohio and present his work on the effect of season and site conditions on soil microbial community activities in a high-elevation mixed conifer forest. This work is part of a larger research project being conducted by Dawson Fairbanks (PhD Candidate) and the Critical Zone Observatory. You can learn more about Chance's research interests here. Congratulations Chance!

The 2019 Earth week SNRExpo showcased the research of SNRE. The gallery lab showed some of the variety of the soils in Arizona and challenged visitors to create a well-draining soil profile and compete in water-infiltration races. Congratulations to SNRE's own Amy Hudson for first place!
Congratulations to Noelle Espinosa, who received the Marshall Foundation Dissertation Fellowship! You can learn more details about Noelle's research here.
As a 2017 William G. McGinnies Award recipient, Martha presented her Ph.D work at this year's annual McGinnies talk. Her work involves linking imaging spectroscopy to microbial biogeochemistry and takes place in the Santa Rita Experimental Range (SRER). You can find more information about the McGinnies award and Martha's work here
Please join us in congratulating Dawson Fairbanks on completing her qualifying exams!
Please join us as the 2017 William G. McGinnies scholarship recipient, Martha Gebhardt, will present her dissertation work November 16th. The talk is titled, "Shrub encroachment alters ecosystem processes: linking imaging spectroscopy and microbial biogeochemistry." You can find more information about her presentation here.
Martha Gebhardt was awarded a $40,000 grant from Freeport McMoRan's Community Investment Fund to coordinate 4 teacher-training events at the Santa Rita Experimental Range (SRER) in the spring with kindergarten- high school teachers from Green Valley and Sahuarita communities. The teachers will spend time at SRER learning hands-on, inquiry based, STEM lessons they will then implement into their classrooms
Martha Gebhardt and Chance Muscarella presented their research at the 15th annual Research Insights in Semiarid Ecosystems (RISE) symposium. Martha presented 2 posters, the first titled, "STEM at SRER" and the second titled, "The use of plant hyperspectral signatures to look below ground at the Santa Rita Experimental Range." Chance presented his poster titled, "Seasonal responses of soil microbial communities in the Jemez River Basin," highlighting the research he and Ph.D student Dawson Fairbanks have done as part of the Catalina-Jemez Critical Zone Observatory. He displayed some of the results they have obtained that quantify the effects of seasonal variation and site factors on microbial enzyme activity rates and biogeochemical cycling of nutrients.
We invite you to submit your abstract to:
B083: The Role of Microbes in Terrestrial Biogeochemical Cycles: Linking Responses to Ecosystem Processes and Environmental Change
Early deadline July 25th / final deadline August 1st.
Microbes play critical roles regulating terrestrial biogeochemical cycles. Linking processes controlling nutrient transformation and storage with disturbance responses and feedbacks to climate change is a global research priority. Studies that integrate biogeochemical approaches focused on nutrient pools and fluxes with microbial ecology approaches examining community physiology, traits, and structure reveal the complexity of interactions influencing ecosystem responses. How do individual microbial traits influence community stability and response to disturbances? How does microbial community structure change across gradients and influence vegetation dynamics? How can we use this information to predict large-scale fluctuations in soil carbon and nutrient storage? Although advances in molecular and genetic tools are improving our understanding of how microbial processes influence ecosystems, questions surrounding the level of detail appropriate to best predict environmental response to change remain. We invite cross-disciplinary studies that investigate microbial-driven responses along environmental gradients, to disturbance, and/or in the context of climate change.
