“…To calculate the decay rate of litter types in different water depths, we calculated the mass loss as: [(original mass loss -average travel loss for that plant species) -remaining mass]. We t the percent mass lost over time using two models: the single exponential model (k) (Olson, 1963) and the decaying coe cient model (k 1 ) (Godshalk et al 1978), as described by Ágoston-Szabó and Dinka (2008). Decay rates were determined by using a nonlinear leastsquares algorithm to t the percent of dry-weight litter mass remaining over time using the Levenberg-Marquardt method in R. The decaying coe cient model (k 1 ) is the most appropriate decay model for comparisons among different litter types and vegetation communities, and for when the decay rate is expected to uctuate.…”

Wetland carbon budgets largely depend on the wetland communities’ relative rate of carbon assimilation and carbon emission. Invasive plants with growth or decomposition patterns that differ from reference plant communities may shift wetland carbon budgets, as may invasive plant suppression efforts. For example, Phragmites australis (European Common Reed), which replaces meadow and cattail marsh in the Laurentian Great Lakes area, has high biomass production and foliar nitrogen, can modify the environment conditions that effect decomposition rates, creates thick stands of slowly decomposing standing dead stems, and is often controlled using broad-spectrum herbicides. Our objectives were to determine if P. australis control efforts in freshwater coastal marshes were sufficient to return net primary productivity, decomposition rates, and environmental conditions to within their pre-invasion range. We find that P. australis invasion had the greatest effect on carbon sequestration when replacing meadow marsh, as opposed to cattail marsh. We conclude that control efforts, one-year post-treatment, dramatically reduce total biomass and carbon assimilation compared to meadow and cattail marsh. However, floating and submersed aquatic vegetation rapidly colonized treated areas, suggesting that continuing plant community recovery may restore the carbon budget in subsequent years.

“…However, reed is unique in that it contains plant structures that decompose at different rates (ÁGOSTON-SZABÓ and DINKA, 2008). Leaves decompose much faster than the main body of the plant (DINKA et al, 2004).…”

“…Lignin is especially resistant to microbial degradation because of its complex chemistry of cross-linked polymers. Lignin may also reduce bioavailability of other cell wall constituents to decomposition (e.g., ÁGOSTON-SZABÓ and DINKA, 2008).Different plants may also vary in their ability to take up or retain environmental contaminants. Because detritus is an important food source for many organisms, contaminant enrichment may impact food webs.…”

Replacement of native macrophyte species with exotic or invasive ones affects the quality of detritus entering streams and can alter nutrient cycles and community structure in aquatic ecosystems. Decomposition of air-dried native hardstem bulrush (Schoenoplectus acutus), invasive southern cattail (Typha domingensis), and exotic common reed (Phragmites australis) were studied in an urban stream (Las Vegas, Nevada, USA) using litter bags. Samples were analyzed for dry mass, lignin, nutrients, trace elements, and macroinvertebrates. Litter type and sediment deposited on plant material influenced material loss. Trace elements arsenic and selenium increased in plant material to concentrations considered marginal for ecosystem contamination by exposure day 76. Mercury increases were inconsistent across plant species and did not exceed limits. Bulrush decomposed faster, and tended to have higher selenium concentrations, than did invasive southern cattail and exotic common reed. Macroinvertebrate communities colonizing litter bags were similar across plant litter types, but differed from mesh-only bags and samples collected with a kick-net. Macroinvertebrate exclusion resulted in significantly lower loss rates, but functional feeding groups such as shredders were not associated with decomposition differences. The caddisfly, Smicridea, physically modified stem material and aided in processing, but microbes appeared most important in biological material breakdown. IntroductionEmergent macrophytes are often important in wetland environments, with shoots providing structure, primary production, and the basis for detrital food webs after senescence. Important processes may be altered when environments are invaded by invasive plant species associated with increased biomass, increased nitrogen availability, and higher litter decomposition rates relative to native plant species (EHRENFELD, 2003). Replacement of native emergent vegetation by aggressive invasives such as common reed (Phragmites australis (CAV.) TRIN. ex STEUDEL) is considered a threat to affected wetlands (MARKS et al., 1994). Ecosystem changes from reed invasion include increased biomass (FINDLAY et al., 2002) which in theory could impact aquatic organisms via increased biological oxygen demand or habitat alteration. The decomposition of organic matter is often considered an integrative measure of biotic and abiotic attributes of stream ecosystems (e.g., TANK et al., 2010). In urban environments, where non-native plants may be common, some ecological processes, like plant breakdown rates, may be insufficiently known (IMBERGER et al., 2008 Later, increased population growth in the area intensified the discharge of water treatment facilities into the Wash resulting in large amounts of channel erosion. This down-cutting and channelization of the Wash caused the water table to fall, draining the previously inundated floodplain. Wetland areas were largely diminished as a result. The Wash ultimately flows into Lake Mead, on the Colorado River, which is a source...
