Realizing the Opportunities of Black carbon in Urban Soils: Implications for Water Quality Management with Green Infrastructure (JOURNAL)
Soil ecosystem processes regulate the carbon cycle, and provide a sink for atmospheric black carbon (BC). Particularly in urban soil, BC may act as an effective sorbent of contaminants in green spaces. We determined soil hydrology, soil carbon pools (organic carbon, black carbon,...
Interactions of predominant insects and diseases with climate change in Douglas-fir forests of western Oregon and Washington, U.S.A. (JOURNAL)
Forest disturbance regimes are beginning to show evidence of climate-mediated shifts associated with global climate change, and these patterns will likely continue due to continuing changes in environmental conditions. Tree growth is largely controlled by the physiological const...
Improved soil temperature modeling using spatially explicit solar energy drivers (JOURNAL)
Modeling the spatial and temporal dynamics of soil temperature is deterministically complex due to the wide variability of several influential environmental variables, including soil column composition, soil moisture, air temperature, and solar energy. Landscape incident solar ra...
Nitrogen inputs drive nitrogen concentrations in U.S. streams and rivers during summer low flow conditions (JOURNAL)
Ecological and human health impairments related to excess nitrogen (N) remain widespread in U.S. streams and rivers despite recent efforts to reduce N loading. Many studies have quantified the relationship between N inputs to watersheds and stream N export in terms of mass loads....
Evaluating Biodiversity Metric Response to Forecasted Land Use Change in the Northern Rio Grande Basin (JOURNAL)
The effects of future land use change on arid and semi-arid watersheds in the American Southwest have important management implications. Seamless, national-scale land-use-change scenarios for developed land were acquired from the US Environmental Protection Agency Integrated Clim...
Adding to the Toolbox for Tidal-Inundation Mapping in Estuarine Areas (JOURNAL)
In estuaries, land-surface and tidal elevation conspire to influence the amount of salt-water inundation in a specific location, ultimately affecting the distribution of estuary vegetation. Plants vary in their tolerances to salinity and inundation. Understanding even small chang...
13C isotopic signature and C concentration of soil density fractions illustrate reduced C allocation to subalpine grassland soil under high atmospheric N deposition (JOURNAL)
We followed soil C fluxes in a subalpine grassland system exposed to experimentally increased atmospheric N deposition for 7 years. Earlier we found that, different from the plant productivity response, the bulk soil C stock increase was highest at the medium, not the high N inpu...
Application of Climate Assessment Tool (CAT) to Estimate Climate Variability Impacts on Nutrient Loading from Local Watersheds (JOURNAL)
A vast amount of future climate scenario datasets, created by climate models such as general circulation models (GCMs), have been used in conjunction with watershed models to project future climate variability impact on hydrological processes and water quality. However, these low...
Depressional wetlands affect watershed hydrological, biogeochemical, and ecological functions (JOURNAL)
Depressional wetlands of the extensive U.S. and Canadian Prairie Pothole Region afford numerous ecosystem processes that maintain healthy watershed functioning. However, these wetlands have been lost at a prodigious rate over past decades due to drainage for development, climate ...
Tale of two storms: Impact of extreme rain events on the biogeochemistry of Lake Superior (JOURNAL)
Climate change is expected to profoundly affect the Great Lakes region of North America. An increase in intensity and frequency of rain events is anticipated to deliver more runoff and to increase riverine inputs to Lake Superior's ecosystem. The effects of these changes on key b...
Connectivity of streams and wetlands to downstream waters: an integrated systems framework (JOURNAL)
Interest in connectivity has increased in the aquatic sciences, partly because of its relevance to the Clean Water Act. This paper has two objectives: (1) Provide a framework to understand hydrological, chemical, and biological connectivity, focusing on how headwater streams and ...
Climate differentiates forest structure across a residential macrosystem (JOURNAL)
The extent of urban ecological homogenization depends on how humans build, inhabit, and manage cities. Morphological and socio-economic facets of neighborhoods can drive the homogenization of forest cover, thus affecting urban ecological and hydrological processes, and ecosystem...
A Framework to Quantify the Strength of the Ecological Links Between an Environmental Stressor and Final Ecosystem Services (JOURNAL)
Anthropogenic stressors such as climate change, fire, and pollution are driving shifts in ecosystem function and resilience. Scientists generally rely on biological indicators of these stressors to signal that ecosystem conditions have been altered beyond an acceptable amount. Ho...
The Significant Surface-Water Connectivity of “Geographically Isolated Wetlands” (JOURNAL)
We evaluated the current literature, coupled with our collective research expertise, on surface-water connectivity of wetlands considered to be “geographically isolated” (sensu Tiner Wetlands 23:494–516, 2003a) to critically assess the scientific foundation of grouping wetlands b...
Detecting spatial regimes in ecosystems (JOURNAL)
Research on early warning indicators has generally focused on assessing temporal transitions with limited application of these methods to detecting spatial regimes. Traditional spatial boundary detection procedures that result in ecoregion maps are typically based on ecological ...
Global Water Clarity: Continuing a Century-Long Monitoring (JOURNAL)
Aquatic systems worldwide are changing due to increasing climate variability and human activities, yet it is difficult to capture such temporal changes without standardized long-term observations [Boyce et al. 2015, Barton et al. 2016]. Unlike the well-established Keeling curve t...
Regime shifts and panarchies in regional scale social-ecological water systems (JOURNAL)
