Slowing the Flow for Climate Resilience (SFCR): Reducing Vulnerability to Extreme Flows and Providing Multiple Ecological Benefits in a Non-Stationary Climate

Current and future hydrologic variability is a major driver underlying large-scale management and modification of inland waters and river systems. In a climate-altered future, identifying and implementing management actions that mitigate anticipated flow regime extremes will be an important component of climate adaptation strategies. These concerns will be particularly focused on extreme flows (floods and droughts) that have ecological, social, and economic importance, and whose impacts are inversely proportion to their frequency.

Quantifying shifting fish migration phenology across the Great Lakes

The timing of major life cycle events (reproduction, flowering, feeding) is set by seasonal environmental cues in many organisms.  Migratory fish in the Great Lakes are largely spring spawners, and they move into tributary rivers as the water warms in March-June.  There is growing evidence that the timing of these migrations is shifting under climate change, creating ever earlier migrations.  These changes in timing may profoundly change which species are present in rivers at a given time, potentially unraveling critical ecological linkages during the dynamic spring warming period.  We are

Predicting the fate and impact of watershed nutrient loads as Lake Michigan's hydrodynamics shift under climate change

Climate change is shifting the hydrodynamics and temperature of both the Great Lakes and their tributary rivers.  Both hydrology and temperature may play potent roles in mediating the magnitude of watershed nutrient load and their fate upon reaching the lake.  Tributary hydrology reflects the source of water (groundwater vs surface runoff) and seasonal timing of discharge, while tributary temperature determines the density difference between river and lake water.  Similarly, mixing patterns in these massive lakes strongly influence whether tributary loads remain near the shore or become dil

Climate Effects on the Culture and Ecology of Sugar Maple

Maple syrup is produced from the sap of sugar maple trees collected in the late winter and early spring. Native American tribes have collected and boiled down sap for centuries, and the tapping of maple trees is a cultural touchstone for many people in the northeast and Midwest. Because the tapping season is dependent on weather conditions, there is concern about the sustainability of maple sugaring as climate changes throughout the region. In spite of this, maple syrup production is increasing rapidly, with demand rising as more people appreciate this natural sweetener. 

NorEaST – Stream Temperature Web Portal Demonstration and Application

Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future projections. Unfortunately, many agencies lack sufficient resources to compile, QA/QC, and make accessible stream temperature data collected through routine monitoring.

A Stream Temperature Inventory Network and Decision Support Metadata Mapper - Evaluating the Resources to Understanding Climate Change Effects on Streams in New England and the Great Lakes States

Stream data for the northeastern U.S. are needed to enable managers to understand baseline conditions, historic trends, and future projections of the impacts of climate change on stream temperature and flow, and in turn on aquatic species in freshwater ecosystems. This project developed a coordinated, multi-agency regional stream temperature framework and database for New England (ME, VT, NH, CT, RI, MA) and the Great Lakes States (MN, WI, IL, MI, IN, OH, PA, NY) by building a community around the efforts of this study.

Characterization of Spatial and Temporal Variability in Fishes in Response to Climate Change

The number of fish collected in routine monitoring surveys often varies from year to year, from lake to lake, and from location to location within a lake.  Although some variability in fish catches is expected across factors such as location and season, we know less about how large-scale disturbances like climate change will influence population variability.  The Laurentian Great Lakes in North America are the largest group of freshwater lakes in the world, and they have experienced major changes due to fluctuations in pollution and nutrient loadings, exploitation of natural resources, intr
