Abstract: The Prairie Pothole wetlands play a significant role in providing important freshwater resources and vital ecosystem services for socio-economic development in North Dakota. The climate in this area is highly variable, with multiyear periods of drought and periods of excess precipitation occurring over the past century, which have markedly influenced wetland ecosystems. Yet little is known of how the biotic communities in these wetlands have responsed to climate variability over this period. Understanding how climate change influences aquatic communities will be important for managing biodiversity and wetland health in these sensitive systems. In this project, we will combine long-term historical datasets (including meteorology, hydrology and water chemistry from USGS) with sediments records from Lake P1, with the aim to evaluate the climate change effects on biological assemblage (diatoms and cladocerans) in the Prairie Pothole wetlands ecosystem, as well as the potential differential effects on different trophic levels (diatoms and cladocerans) at Lake P1, Cottonwood Lake Study Area, North Dakota. In turn, this research can help us get a better understanding of the Prairie Pothole wetlands ecosystem and can be used by managers for conserving wetlands in the future.
