Decoupled trophic responses to long-term recovery from acidification and associated browning in lakes.

ABSTRACT: Increases in the concentration of dissolved organic matter (DOM) have been documented in many inland waters in recent decades, a process known as "browning". Previous studies have often used space-for-time substitution to examine the direct consequences of increased DOM on lake ecosystems. However, browning often occurs concomitant with other ecologically important water chemistry changes that may interact with or overwhelm any potential ecological response to browning itself. Here we examine a long-term (~20 year) dataset of 28 lakes in the Adirondack Park, New York, USA, that have undergone strong browning in response to recovery from acidification. With these data, we explored how primary producer and zooplankton consumer populations changed during this time and what physical and chemic
