“As an historically underrepresented graduate student in biology, I believe that diversifying STEM fields highly depends on outreach programs. I became interested in helping create a more inclusive science space when I looked around my higher education classes and didn’t see the very diverse America I grew up in. As our […]
“My dad works for the Navajo EPA, so conversation about the land, nature, and environmental work on the Navajo Nation was common in our home,” said Harvey. Her family raised horses and cattle and developed their own management plan for grazing. For an ethnobotany project in high school, she explored […]
“When I decided to pursue a career in science, my vision of what it would entail was hazy, to say the least. From growing up watching NOVA on PBS to exploring the ecological diversity of deserts, glaciers, coasts, and tundra during my undergraduate career, I knew that science excited me. […]
PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University. Graduate student benefits include a stipend (teaching assistantship or research assistantship), tuition waiver, health insurance, and payment of non-tuition fees. The Ecoss mission is to conduct high-impact, innovative […]
Warming global temperatures are changing life on every continent on Earth, including Antarctica, where more microbes are moving in to territory previously covered by ice. How these microbes respond to warming offers us clues about what future Antarctica will look like and who will thrive there. Microbial ecologist and PhD […]
Understanding how population-level dynamics contribute to ecosystem-level processes is a primary focus of ecological research and has led to important breakthroughs in the ecology of macroscopic organisms. However, the inability to measure population-specific rates, such as growth, for microbial taxa within natural assemblages has limited ecologists’ understanding of how microbial […]
Arctic tundra soils store large amounts of carbon (C) in organic soil layers hundreds to thousands of years old that insulate, and in some cases maintain, permafrost soilsl,2. Fire has been largely absent from most of this biome since the early Holocene epoch3, but its frequency and extent are increasing, […]
Many thermophiles catalyse free energy-yielding redox reactions involving nitrogenous compounds; however, little is known about these processes in natural thermal environments. Rates of ammonia oxidation, denitrification and dissimilatory nitrate reduction to ammonium (DNRA) were measured in source water and sediments of two ∼80°C springs in the US Great Basin. Ammonia […]
