Balancing stability and flexibility in adaptive governance: an analysis of tools available in U.S. environmental law
(JOURNAL) [Published : Jun 30, 2017]
Adaptive governance must work “on the ground,” that is, it must operate through structures and procedures that the people it governs perceive to be legitimate and fair, as well as incorporating processes and substantive goals that are effective in allowing social-ecological syste...
The Role of Law in Adaptive Governance
(JOURNAL) [Published : Mar 01, 2017]
The term “governance” encompasses both governmental and nongovernmental participation in collective choice and action. Law dictates the structure, boundaries, rules, and processes within which governmental action takes place, and in doing so becomes one of the focal points for an...
Land-Use/Land-Cover Change from Socio-Economic Drivers and Their Impact on Biodiversity in Nan Province, Thailand
(JOURNAL) [Published : Jan 26, 2019]
The rate of deforestation declined steadily in Thailand since the year 2000 due to economic transformation away from forestry. However, these changes did not occur in Nan Province located in northern Thailand. Deforestation is expected to continue due to high demand for forest pr...

Informing Future Risks of Record‐Level Rainfall in the United States
(JOURNAL) [Published : Apr 10, 2019]
The changing risk of extreme precipitation is difficult to project. Events are rare by definition, and return periods of heavy precipitation events are often calculated assuming a stationary climate. Furthermore, ensembles of climate model projections are not large enough to full...
Application of Climate Assessment Tool (CAT) to Estimate Climate Variability Impacts on Nutrient Loading from Local Watersheds
(JOURNAL) [Published : Aug 01, 2018]
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...
A Climate Change Adaptation Strategy for Management of Coastal Marsh Systems
(JOURNAL) [Published : May 01, 2017]
Sea level rise is causing shoreline erosion, increased coastal flooding, and marsh vulnerability to the impact of storms. Coastal marshes provide flood abatement, carbon and nutrient sequestration, water quality maintenance, and habitat for fish, shellfish, and wildlife, includin...
Longitudinal thermal heterogeneity in rivers and refugia for coldwater species: effects of scale and climate change
(JOURNAL) [Published : Jan 01, 2018]
Climate-change driven increases in water temperature pose multiple challenges for aquatic organisms. Predictions of climate change impacts to biota typically do not account for fine-grained spatiotemporal patterns of stream networks; yet patches of cooler water within rivers c...
Evaluation of Climate Change Impact on Drinking Water Treatment Plant Operation
(JOURNAL) [Published : Mar 13, 2014]
It is anticipated that global climate change will adversely impact source water quality in many areas of the United States and, therefore, will influence the design and operation of current and future drinking water treatment systems. Some of these impacts may lead to violations ...
Carbon Stable Isotope Values in Plankton and Mussels Reflect Changes in Carbonate Chemistry Associated with Nutrient Enhanced Net Production
(JOURNAL) [Published : Feb 14, 2018]
Coastal ecosystems are inherently complex and potentially adaptive as they respond to changes in nutrient loads and climate. We documented the role that carbon stable isotope (δ13C) measurements could play in understanding that adaptation with a series of three Ecostat (i.e...
Simulated juvenile salmon growth and phenology respond to altered thermal regimes and stream network shape
(JOURNAL) [Published : Dec 22, 2017]
Context. Thermally diverse habitats may afford fish protection from climate change by providing opportunities to behaviorally optimize growing conditions. However, it is unclear what role the spatial properties of river networks will play in determining risk. Objectives. We hypot...
