1.Dams disrupt the river continuum, altering hydrology, biodiversity and energy flow. Although research indicates that tributary inputs have the potential to dilute these effects, knowledge at the food‐web level is still scarce. 2.Here, we examined the riverine food‐web structure of the Colorado River below Glen Canyon Dam, focusing on organic […]
Julia Stuart, Ecoss PhD student in the Mack Lab, won an Outstanding Student Poster Award in Biogeosciences at the 2017 meeting of the American Geophysical Union, New Orleans, LA. Her poster was titled “Plant, microbiome, and biogeochemistry: Quantifying moss-associated N2 fixation in Alaska”
Bruce Hungate, Director of the Center for Ecosystem Science and Society at Northern Arizona University, is one of the coauthors of this new study. He was surprised to find a symbiotic relationship between plants and a certain fungus boosted growth even without nitrogen. Hear about the study in this short […]
Most organic carbon (C) in soils eventually turns into CO2 after passing through microbial metabolic pathways, while providing cells with energy and biosynthetic precursors. Therefore, detailed insight into these metabolic processes may help elucidate mechanisms of soil C cycling processes. Here, we describe a modeling approach to quantify the C […]
Several Ecoss members presented at the 2015 AGU fall meeting. Topics ranged from permafrost C cycle responses to climate change, to priming effects on soil C, to forest fires in the Arctic. Below you can find an overview of the presentations; click on the presentation title for more information at the AGU meeting page. […]
Bruce Hungate, Director of Ecoss gave the keynote address to the Goldschmidt Conference in Prague this week for the session, “How do Biogeochemical Cycles Operate on a high-CO2 Planet?” The abstract for Dr. Hungate’s keynote address was entitled “Rising CO2 and the Biogeochemistry of Soil Microbial Ecosystems.”
Join ECOSS and gain career ready skills! The Center for Ecosystem Science and Society (ECOSS) provides valuable undergraduate experiences in ecosystems and climate ecology. Currently there are three avenues to work with ECOSS as an undergraduate student: student worker positions in the Laboratory or field, The ECOSS mentoring program, and […]
ESSTE: A new undergraduate program sponsored by the U.S. Department of Agriculture ESSTE is a unique, 3-semester internship and mentorship opportunity for undergraduate students to help prepare the next generation to address the challenge of increasing drought, fires, and floods. Background The Southwest is facing tremendous environmental challenges as a […]
ESSTE es una experiencia de tres semestres con oportunidades como pasantías y mentorías para estudiantes de cualquier licenciatura. El programa busca preparar a las próximas generaciones para enfrentarse a desafíos como sequías, incendios e inundaciones. El programa ESSTE fue creado en respuesta a la falta de oportunidades de entrenamiento y […]
Interviewed by STICH Scholar and Ecoss social media specialist Kayla Blair. Meet Natasha Wesely, a second year PhD student in Dr. Andrew Richardson’s lab. Natasha focuses on modeling different major ecosystem processes. One of her projects involves her creating a new soil restoration model to investigate how soil respiration is driven […]
