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 […]
Shifts in the extent of the boreal forest during past warm intervals and correlations between climate and the position of the forest–tundra ecotone suggest that recent temperature increases will facilitate forest expansion into tundra ecosystems. In this study, we used a unique set of high-resolution repeat photographs to characterize white […]
“Today I am taking the flux puppy for a walk at @HarvardForest to measure stem respiration,” NAU postdoctoral researcher Tim Rademacher recently tweeted. With it, a photo of a small white chamber fastened to a tree trunk (think half Dixie cup, half electrode) and hooked at the other end to […]
Roads are a main threat to biodiversity conservation in the Amazon, in part, because roads increase access for hunters. We examine how increased landscape access by hunters may lead to cascading effects that influence the prey community and abundance of the jaguar (Panthera onca), the top Amazonian terrestrial predator. Understanding […]
The concentration detection threshold (CDT) is the concentration of particles in solution beyond which a (serial dilution) assay detects particle presence. By our account, CDTs typically are not estimated but are fixed at some value. Setting a CDT to zero (d=0d=0) implies perfect detection, a common assumption, and setting d>0d>0 […]
We’ve got your number: Tracing the source of invasive Japanese beetles March 9, 2016 Sonya Daw news.nau.edu Like a Southern drawl popping up on the West Coast, our accents mark us as newcomers. With time they fade, leaving only traces of our past in the occasional slip of a word. […]
Soil is a complex ecosystem with diverse microenvironments ranging from bulk soil with low quality substrates and no or very limited microbial growth, to high quality C-rich environments near decomposing litter and rhizosphere where microbial growth and death rates are high. Soil contains different microbial communities, supports varying microbial activities […]

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 […]
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. The ESSTE program is in response to an awareness that there is a lack of job training and placement in fields related […]
