Název v původním jazyce

Wetland ecosystem changes after three years of phosphorus addition

Popis výsledku v původním jazyce

We used oligotrophic, P-limited herbaceous wetlands of northern Belize to assess how changes in nutrient availability impact species composition and ecosystem processes. The P, N, and NP enrichment plots were established in replicated marshes of three salinity levels to document potential salinity constraints. Addition of P or combination of N and P resulted in rapid switch frorn a microphyte (cyanobacterial mats, CBM) to macrophyte (Eleocharis spp., Typha domingensis) domination, while N addition did not have any impact. The switch was caused by significant changes in Eleocharis stein density and height, and consequently, the aboveground biomass, which increased from an average 120 g m(-2) in control and +N plots to > 500 g m(-2) in +P and +NP plots.Decreased light under the dense canopy of Eleocharis in +P and +NP plots caused significant reduction in CBM growth. Biomass of Eleocharis in +P and +NP plots decreased with increasing salinity, but salinity did not affect biomass product
