Patterns of inorganic inputs and movements of nutrients through soils, groundwater and surface waters
Nitrogen, phosphorus and other mineral nutrients are cycled through the ecosystem by way of decay and disturbances such as fire and flood. In excessive quantities nitrogen and other nutrients can have far-reaching and harmful effects on the environment.
High-resolution monitoring of long term changes in physical limnology in the McMurdo Dry Valleys, Antarctica
Poster Number: 39 Presenter/Primary Author: Hilary Dugan In the McMurdo Dry Valleys of Antarctica, permanently ice-covered, closed basin lakes are the terrestrial endpoints of hydrologic flow in the watersheds, and are therefore excellent indicators of g
Greenhouse gas emissions from small streams in a lake-rich landscape: the importance of incorporating methane
Poster Number: 37 Presenter/Primary Author: John Crawford Small streams may be important components of regional and global carbon budgets.
Nitrogen cycling “hotspots”: An approach for watershed scale assessments
Poster Number: 28 Presenter/Primary Author: Peter Baas The high level of spatial and temporal heterogeneity in nitrogen cycling processes hinders our ability to develop an ecosystem-wide understanding of this cycle.
Scale, Consumers and Lotic Ecosystem Rates (SCALER)
Poster Number: 25 Presenter/Primary Author: Janine Rueegg A key aim of SCALER is to allow extrapolation of typical experiments in streams to scales relevant to use or protection of the environment (i.e.
Edaphic Factors affect the abundance and activity of ammonia oxidizing microbes in Soils at Coweeta LTER
Poster Number: 24 Presenter/Primary Author: Jeff Norman Ammonia Oxidation is the rate-limiting step of nitrification, a critical nitrogen transformation that controls nitrogen mobility in terrestrial ecosystems. Ammonia oxidation is performed by t
