Zoe G. Cardon is an American ecosystems ecologist focused on observing and understanding ecosystem interactions in the rhizosphere. She has also played an integral role in developing systems to better study the rhizosphere without digging it up and interfering with the ecosystems using stable isotopes and mathematical modeling. [1] Cardon is currently a senior scientist at the Marine Biology Laboratory at the Ecosystems Center and an adjunct professor of ecology and evolutionary biology at Brown University. [2] [3] She is credited with helping to establish the National Microbiome Initiative at the White House Office of Science and Technology Policy in Washington, D.C. [1]
Cardon was born in Logan, Utah to parents Guy Cardon and Joyce Johnson Cardon, owners of the Bluebird Restaurant and Candy Co. She grew up playing the piano, performing as a soloist in the Utah Symphony and the USU Orchestra. She has also won four piano competitions at the Utah State Fair, and has published poetry. [4] She was named a Presidential Scholar from Utah in 1983. In 1988, she graduated with a B.S in Biology and a B.A in Spanish from Utah State University as valedictorian in the College of Science and Scholar of the Year in the university's Robins Awards. [5] She went on to receive her Ph.D in Biological Sciences at Stanford University in 1994. She completed her education by conducting research as a DOE Global Change Distinguished Postdoctoral Fellow at the University of California, Berkeley. [1]
Cardon began as an assistant professor at Bowdoin College for a year (1996–1997) before moving to the University of Connecticut (UConn), where she received an Outstanding Advisor Award for her enthusiasm and accessibility as an advisor and assistant professor. One of her advisees, Andy Czaja, said of Cardon, "Zoe is always willing to help, no matter what she's doing. A lot of times, she'll offer help even without asking. She sends e-mail, saying 'I was thinking about your project, what about this?'" [6] She worked at UConn until 2007, eventually becoming head of the Biology Honors Program, and associate director and Graduate Program Director of the Center for Integrative Geosciences. In 2002, Cardon was awarded the Sarah and Daniel Hrdy Visiting Fellowship in Conservation Biology at Harvard University, which is awarded to distinguished individuals who will work and study within the Department of Organismic and Evolutionary Biology. [7] In 2007, Cardon assumed a position as Senior Scientist at the Ecosystems Center, Marine Biological Laboratory, in Woods Hole, MA. [2] She is also an adjunct professor of Ecology and Evolutionary Biology at Brown University. [3]
Cardon's research focuses largely on the rhizosphere and interactions between the micro- and macro-organisms within it. Her work draws from multiple disciplines and perspectives in order to understand how interactions among plant roots, microbes, and minerals facilitate exchanges of resources in these systems. In 2015 Cardon participated in a forum on "Microbiome Innovation: Roadmap to the Future" that was hosted by the White House Office of Science and Technology Policy. [8]
Cardon's research focuses largely on interactions within the rhizosphere and understanding the complex relationships between microbes, plants, and soils. [9] Her research is highly influential and she has published in many peer-reviewed journals such as Proceedings of the National Academy of Sciences of the United States of America , Soil Biology and Biochemistry , Journal of Cell Science , Plant Physiology, and more. Listed below are a few of her most highly cited publications:
In 2018 Cardon was named a fellow of Ecological Society of America. [14] Cardon was elected a fellow of the American Association for the Advancement of Science in 2021. [15]
A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have special adaptations to take in extra oxygen and to remove salt, which allow them to tolerate conditions that would kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago.
The rhizosphere is the narrow region of soil or substrate that is directly influenced by root secretions and associated soil microorganisms known as the root microbiome. Soil pores in the rhizosphere can contain many bacteria and other microorganisms that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and sugars released by roots, termed root exudates. This symbiosis leads to more complex interactions, influencing plant growth and competition for resources. Much of the nutrient cycling and disease suppression by antibiotics required by plants occurs immediately adjacent to roots due to root exudates and metabolic products of symbiotic and pathogenic communities of microorganisms. The rhizosphere also provides space to produce allelochemicals to control neighbours and relatives.
Soil respiration refers to the production of carbon dioxide when soil organisms respire. This includes respiration of plant roots, the rhizosphere, microbes and fauna.

Joy K. Ward is an American evolutionary biologist studying the impact of the environment on plants and ecosystems. She began a new role as the dean of the College of Arts & Sciences at Case Western Reserve University on July 1, 2020 - leaving behind her professorship at the University of Kansas. Her research on plant life has gained her notoriety in many scientific research fields. Aside from her work in the lab, she is also a strong advocate for advancing underrepresented communities' scientific learning and careers. As part of her deanship at the University of Kansas, Ward was an important factor in increasing the number of underrepresented individuals who held faculty positions in STEM subjects. Notably, as a result of her research efforts, she was awarded the Presidential Early Career Award for Scientists and Engineers by U.S. President Barack Obama.
Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans. These bacteria could fix nitrogen, in time multiplied, and as a result released oxygen into the atmosphere. This led to more advanced microorganisms, which are important because they affect soil structure and fertility. Soil microorganisms can be classified as bacteria, actinomycetes, fungi, algae and protozoa. Each of these groups has characteristics that define them and their functions in soil.
Soil carbon storage is an important function of terrestrial ecosystems. Soil contains more carbon than plants and the atmosphere combined. Understanding what maintains the soil carbon pool is important to understand the current distribution of carbon on Earth, and how it will respond to environmental change. While much research has been done on how plants, free-living microbial decomposers, and soil minerals affect this pool of carbon, it is recently coming to light that mycorrhizal fungi—symbiotic fungi that associate with roots of almost all living plants—may play an important role in maintaining this pool as well. Measurements of plant carbon allocation to mycorrhizal fungi have been estimated to be 5 to 20% of total plant carbon uptake, and in some ecosystems the biomass of mycorrhizal fungi can be comparable to the biomass of fine roots. Recent research has shown that mycorrhizal fungi hold 50 to 70 percent of the total carbon stored in leaf litter and soil on forested islands in Sweden. Turnover of mycorrhizal biomass into the soil carbon pool is thought to be rapid and has been shown in some ecosystems to be the dominant pathway by which living carbon enters the soil carbon pool.
The root microbiome is the dynamic community of microorganisms associated with plant roots. Because they are rich in a variety of carbon compounds, plant roots provide unique environments for a diverse assemblage of soil microorganisms, including bacteria, fungi, and archaea. The microbial communities inside the root and in the rhizosphere are distinct from each other, and from the microbial communities of bulk soil, although there is some overlap in species composition.

The plant microbiome, also known as the phytomicrobiome, plays roles in plant health and productivity and has received significant attention in recent years. The microbiome has been defined as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties. The term thus not only refers to the microorganisms involved but also encompasses their theatre of activity".
