AWRI Collaborative Research:
How will water level fluctuations alter the microbial community in coastal wetland ecosystems?
Coastal wetlands are particularly sensitive to water level fluctuations (WLF), given their location at the land-water interface. Alternate dry and wet periods associated with WLF can result in sediment exposure and oxidation, which can cause substantial release of nutrients, such as phosphorus (P). The nutrient released from the sediment could stimulate algal blooms, resulting in impaired water quality, reduced ecotourism, and impacted fisheries.
Dr. Solange Duhamel from Columbia University is currently working with researchers at AWRI, Dr. Geraldine Nogaro and Dr. Alan Steinman, to assess 1) the effects of WLF on P release from the sediment to the water column and 2) the bioavailability of the P released for microbial nutrition in the water column. Sediment cores were collected in August 2013 from moderately nutrient-rich and highly enriched wetlands, which are part of the Muskegon Lake Area of Concern, and allowed to dry simulating water level declines.
In October 2013, the sediment cores were rewetted with surface water collected at the respective sites, simulating water level recovery. Experiments are being conducted to determine if nutrients released from the desiccated/rewetted sediments into the water column affect structure and function of the microbial community (bacteria and phytoplankton). This research will provide important information on the ecological impacts of WLF on Great Lakes coastal wetlands, especially with regard to potential negative effects of water level fluctuations on water quality.
