“…The overland hydrologic connectivity between limesink wetlands and adjacent streams is temporally discontinuous. The only exceptions occur during major flood events when overland flooding permits exchange of materials with adjacent forests, streams, and other wetlands (Michener et al 1998). Furthermore, most limesink wetlands do not represent an important source of material to streams through groundwater flow because they are confined by impermeable clay lenses (Hendricks and Godwin 1952;Lide et al 1995).…”

A set of three relatively pristine seasonally inundated limesink wetlands and one riparian wetland was studied over a 4-6 month long inundation period in 2001. Patterns in organic matter properties and oxygen consumption in the water column followed a previously documented ecological gradient based on soil composition, vegetation type, and canopy cover. The full canopy, cypress-gum swamp had the highest mean concentrations of dissolved organic carbon (DOC; 26.2 mg/l) and dissolved lignin (sum 6; 299 lg/l) with lower concentrations observed in the partial canopy, cypress savanna (22.0 mg/l DOC; 252 lg/l sum 6) and the open marsh savanna (20.6 mg/l DOC; 135 lg/l sum 6), respectively. During the inundation period, DOC increased in concentration, dissolved lignin decreased, and d 13 C shifted to more positive values which collectively indicate a large reduction in the percentage of aromatic carbon during the inundation period. All wetlands had very high concentrations of organic matter, yet microbial oxygen consumption was almost always stimulated by the addition of glucose rather than inorganic nutrients. Stimulation by glucose suggests that there were very small pools of highly bioavailable forms of DOC in the wetlands. A larger pool of moderately bioavailable organic matter had the capacity to sustain microbial oxygen consumption rates under dark conditions for at least 15 d. During the inundation period, the cypress-gum swamp had the lowest average rates of whole water oxygen consumption (1.0 lM/h) with increasing rates observed in the cypress savanna (1.3 lM/h), marsh savanna (1.6 lM/h), and riparian wetland (1.9 lM/h), respectively. The lignin compositional fingerprint varied across the gradient of limesink wetlands, and was useful for identifying different sources of vascular plant-derived DOM. Vascular plant production, algal production, microbial respiration, and UV degradation are all important drivers of DOM cycling, and the consistencies observed in this initial assessment of seasonally inundated limesink wetlands suggest they vary in predictable ways across the ecological gradient.

“…Whereas other authors have suggested that habitat is only of secondary importance when describing fish and mussel distributions, the results of this study suggest that fish and mussel community structure is closely related to stream size and suitable habitat. This is not surprising, in that lotic fish faunas are often closely tied to landscapelevel processes (Schlosser 1991) and in the ACF basin, fish and mussel community structure is regulated, in part, by interactions at the streamfloodplain interface (Michener et al 1998). In addition, in streams that were historically degraded, some fish species may have recovered, whereas mussels have not.…”

“…We estimate that riparian areas cover at least 8.9 million hectares (based on 30-m buffers) to 13. (Michener et al 1998, Palik 1999). Using these data, we estimated Illinois riparian area at nearly 1.6 million hectares, substantially higher than either soil or buffer estimates (table 4).…”

Many different types of riparian areas can be found throughout the seven-State Midwest Region. The ecological and social importance of riparian areas as landscape elements is undisputed (e.g., see Verry et al. 2000); however, there is great uncertainty about the cumulative importance of riparian areas in many landscapes and regions. This is a consequence of inadequate inventory data on the extent, type, and land use/land cover of riparian resources. The seven-State Midwest Region of the continental United States is no exception (figure 1). This region is one of the most water-rich areas in the continental United States, yet we are not aware of any general accounting of amount, type, or land use of riparian resources here. Because of the lack of regional data on riparian resources, it is difficult to determine the degree to which different types of riparian areas receive protection, the extent of change in riparian land use/land cover over time, and the social and economic benefits derived from different types of riparian land use. At issue is the availability and adequacy of riparian resource information used to make policy and management decisions in the region.
