THE TIMES THEY ARE A CHANGING - CAN WE CONSERVE OR DESIGN METABOLIC REGIMES TO PROTECT RIVER SPECIES AND ECOSYSTEMS?
River ecosystems vary widely in the magnitude and timing of primary productivity and allochthonous carbon supply. These differences in energetic inputs to river ecosystems are ultimately determined by river climate (light, flow, and thermal regimes) and constrained by physical disturbance and nutrient supply. For many rivers, climate and land use change are leading to significant alterations in river climate, increasingly frequent or severe physical disturbances and increased nutrient loading. These impacts propagate into shifts in metabolic regimes. Reduced energy supply is likely to reduced secondary production, while shifts in the timing of energy input peaks may disadvantage those consumers whose life history is timed to take advantage of predictable patterns of energy supply. Efforts to protect or recover freshwater biodiversity will likely be more successful if they can restore critical aspects of the metabolic regime.
