Our faculty and staff know two heads are better than one. It’s why they build teams dedicated to tackling specific, scientific questions related to the natural resources in Nebraska, North American and beyond.
Our lab focuses on developing innovative solutions to the growing wildlife conservation and management needs in multi-functional landscapes where there are competing interests for agricultural production, wildlife conservation, and ecosystem services.
Long-term greenhouse gases and carbon sequestration study AmeriFlux Network, Mead sites (US-Ne1, US-Ne2, and US-Ne3) has been in continuous operation since 2001 and currently lead by Dr. Andrew Suyker to determine how much carbon can be stored in dryland and irrigated cropping systems, and what soil, plant, and atmospheric factors regulate C sequestration. Recently, the sites joined the AmeriFlux Core Site Network and will be funded on a long-term basis.
Our goal is to monitor and model the flow of water through natural and human dominated ecosystems in order to understand how ecosystems function and how to utilize water more efficiently for food production. Our research is highly interdisciplinary and works at the interfaces of ecology, hydrology, agronomy, and geophysics.
Exploring Ecosystem Function at Multiple Scales -Dr. John Gamon studies the "breathing of the planet" – the exchanges of carbon and water vapour between the biosphere and the atmosphere that affect ecosystem productivity and help regulate our atmosphere and climate. Of particular interest are the effects of disturbance (fires, succession, weather events and climate change) on these basic processes. Additional research questions involve the detection of plant physiology, ecosystem function, species composition, and biodiversity using non-contact sampling methods. Much of this work is done with optical monitoring (remote sensing and automated field methods), and entails the development of new monitoring methods and related informatics tools.
The Messer Research Group, interests are at the often-ignored intersection of agricultural engineering, ecology, and chemistry of emerging contaminants. The research interests include:
- Emerging Sensor Technologies
- Hydrologic and Stable Isotope Tracer Techniques
- Nutrient and Pesticide Cycling, Fate, and Transport
- Agricultural Systems
- Surface Water Hydrology Modeling
- Ecosystem Restoration
- Engineering Education
- Environmental Impacts in Developing Countries
- Groundwater Hydrology Modeling
- Restoration Assessments of Ecosystem Services
- Environmental Policy
The Pegg Lab conducts research centered on the ecology of flowing systems, fisheries management, the impacts of aquatic nuisance species, and restoration ecology.
The Qi Lab asks:
- How does the ecosystem change at different scales and over time under the changing climate?
- What are the drivers and consequences of the ecosystem change?
Yi Qi studies the emerging challenge of answering these questions, the method to observe, store and analyze massive earth observatory data, and ultimately extract the spatio-temporal pattern of the ecosystem change and integrate this knowledge to the decision-making process.
