Tidal freshwater wetlands (TFW), which lie at the interface of saltwater and freshwater ecosystems, are predicted to experience moderate salinity increases due to sea level rise. Increases in salinity generally suppress CH4 production, but it is uncertain to what extent elevated salinity will affect CH4 cycling in TFW. It is also unknown whether CH4 production will resume when freshwater conditions return. The ability to produce CH4 is limited to a monophyletic group of the Euryarchaeota phylum called methanogens (MG), who are limited to a small number of substrates (e.g., acetate, H2, and formate) produced from the breakdown of fermentation products. …

Effective management of pond breeding amphibians requires identifying suitable breeding habitat and its use by different species. Suitable breeding habitat is largely characterized by pool type, physical habitat, and position within the landscape. Parameters such as vegetative cover, hydrology, and water chemistry are known to influence amphibian occupancy of vernal pools. While seasonal vernal pools have been the focus of conservation efforts, pools that are an artifact of anthropogenic disturbance, such as road ruts, may be an important component of the landscape for amphibians. The role of wetland isolation within a landscape has been well studied, but less consideration has …

The goals of this study are: 1) to use an eddy-covariance system to continuously measure wetland-atmosphere CO2 and CH4 exchange in a restored forested wetland, 2) to quantity C sequestration in plant biomass and soils in restored (Kimages Creek watershed) and old-growth (Harris Creek watershed) forested wetlands, and 3) to establish a shared long-term, shared research and teaching platform centered on eddy-covariance tower measurements. Since the old-growth forest wetland has had longer to accumulate C, the current C stocks are likely much larger than those of the restored wetland; however, the rate of C accumulation (i.e., C sequestration or net …
