Why is periphyton so abundant in theEverglades?• Salinity – similar periphyton mats exist across broad salinityrange with species swapping functional roles across spectrum• Temperature – high temperatures with relatively lowfluctuations allow sustained production throughout the year• Nutrients – periphyton sustains highest production underlowest nutrient concentrations indicating efficient recycling• Consumer Interactions – periphyton feeds the food web butreduced edibility and high turnover mask consumer effects• Hydrology – communities are adapted to particularhydroperiod regimes and recover quickly after desiccating
