¡Aplica a ESSTE!
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 […]
Apply to ESSTE!
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 […]
Ecosystem carbon transit versus turnover times in response to climate warming and rising atmospheric CO2 concentration
Ecosystem carbon (C) transit time is a critical diagnostic parameter to characterize land C sequestration. This parameter has different variants in the literature, including a commonly used turnover time. However, we know little about how different transit time and turnover time are in representing carbon cycling through multiple compartments under […]
Developing climate-smart restoration: Can plant microbiomes be hardened against heat waves?
Heat waves are increasing in frequency and intensity, presenting a challenge for the already difficult practice of ecological restoration. We investigated whether pre-heating locally sourced rhizosphere soil (inoculum) could acclimatize plants to a field-imposed heat wave in a restoration setting. Soil heating in the laboratory caused a marked shift in […]
A Dynamic Landsat Derived Normalized Difference Vegetation Index (NDVI) product for the conterminous United States
Satellite derived vegetation indices (VIs) are broadly used in ecological research, ecosystem modeling, and land surface monitoring. The Normalized Difference Vegetation Index (NDVI), perhaps the most utilized VI, has countless applications across ecology, forestry, agriculture, wildlife, biodiversity, and other disciplines. Calculating satellite derived NDVI is not always straight-forward, however, as […]
A global synthesis reveals biodiversity loss as a major driver of ecosystem change
Pollution scenarios and anthropogenic warming are familiar examples of human-caused stress on the environment. But human-driven loss of biodiversity itself robs ecosystems of essential players and services, damaging ecosystem function. Ecoss research examined the effects of various environmental stressors on plant growth and decomposition, two crucial processes in any ecosystem. […]
Cumulative response of ecosystem carbon and nitrogen stocks to chronic CO2 exposure in a subtropical oak woodland
Rising atmospheric carbon dioxide (CO2) could alter the carbon (C) and nitrogen (N) content of ecosystems, yet the magnitude of these effects are not well known. We examined C and N budgets of a subtropical woodland after 11 yr of exposure to elevated CO2. We used open-top chambers to manipulate CO2 […]
Linking Biogeochemistry and Microbial Community Chemistry
Overview The identities of organisms profoundly influence ecosystems, and microbial diversity is vast. The obvious disconnect between this diversity and its treatment in C cycling models is perhaps the best manifestation of the common complaint that so much physiology, taxonomy, ecology, and diversity is ignored when microbial communities are described […]
