Simeon Yurek is a Research Ecologist at the USGS Wetland and Aquatic Research Center.
RESEARCH INTERESTS:
Identifying optimal strategies for restoration decision making and adaptation planning in coastal areas, given uncertainty in environmental conditions and risk tolerance of decision makers
Ecological modeling of hydrologically pulsed ecosystems with complex geomorphology, dynamic food webs, animal movement, and predator-prey systems
Ensemble-style modeling of alternative scenarios of biophysical and ecological conditions and management decision making, with a goal of predicting ecological outcomes and identifying tradeoffs and risks associated with ecosystem services of interest
Science and Products
Water, Water Everywhere: Adapting Water Control Operations and Floodplain Conservation Planning to Global Change
Global change processes are producing shifts in temperature, precipitation, and seasonal streamflow regimes across North America. Much of the floodplain hydrology in the U.S. is managed through water control operations, often implemented on short time scales (e.g., weekly decisions), in response to short-term changes in precipitation. This operational model does not account for potential long-term
Future of Aquatic Flows: Towards a National Synthesis of Streamflow Regimes Under a Changing Climate
In ecosystems characterized by flowing water, such as rivers and streams, the dynamics of how the water moves - how deep it is, how fast it flows, how often it floods - have direct effects on the health, diversity, and sustainability of underlying communities. Yet increasingly, climate extremes like droughts and floods are disrupting fragile stream ecosystems by specifically changing their interna
Future of Aquatic Flows: Exploring Changes in the Freshwater/Saltwater Interface and Related Impacts to Aquatic Species
Coastal ecosystems are uniquely vulnerable to changes in the quantity and quality of freshwater discharge. With a warming climate, changes in freshwater discharge into estuaries will interact with rising sea levels. Coastal natural resource managers need guidance on the potential impacts and vulnerabilities to better manage the risks to aquatic species and habitats and to mitigate species decline
Across Trophic Level System Simulation (ATLSS) Program for the Greater Everglades
Goals of the ATLSS Program are to help achieve a better understanding of components of the Everglades ecosystem, to provide an integrative tool for empirical studies, and to apply these tools to an adaptive management framework.
North Carolina Sustainable Rivers Program
In 2002, The Nature Conservancy and the U.S. Army Corps of Engineers launched a collaborative effort to find more sustainable ways to manage river infrastructure to maximize benefits for people and nature. As of 2021, the Sustainable Rivers Program study area includes 40 rivers, 89 reservoirs, and 10,953 downstream river miles. The USGS South Atlantic Water Science Center and USGS Wetland and...
Coastal Resource Evaluation for Management Application (CREMA)
Coastal environments are dynamic systems that provide high ecological, economical, recreational, and cultural value. Managing coastal systems requires a comprehensive understanding of the complex interactions between geological and ecological processes, as well as the ability to predict both the near-term and long-term impacts of storms and sea-level rise. The Coastal Resource Evaluation for...
Real-time Coastal Salinity Index for monitoring coastal drought and ecological response to changing salinity values
Many coastal areas are experiencing departures from normal conditions due to changing land use and climate patterns, including increased frequency, severity, or duration of floods and droughts, in some cases combinations of the two. To address these issues, the U.S. Geological Survey developed the Coastal Salinity Index (CSI) to identify and communicate fluctuating salinity conditions due to such
Climate Change Adaptation for Coastal National Wildlife Refuges
National Wildlife Refuges provide habitat for important fish and wildlife species and services that benefit coastal communities, like storm-surge protection. USGS scientists are helping coastal refuges plan for and adapt to sea-level rise.
