CAN ACID DEPOSITION RECOVERY AND CHANGING WATER CLARITY INSULATE FISH IN MOUNTAIN LAKES FROM CHANGING CLIMATE CONDITIONS?
With over two decades of declining acid deposition across eastern North America, we are seeing a strong recovery of coldwater fish in many historically acidified lakes in New York State. Unfortunately, while ecological recovery from acidification is progressing in surface water environments, these systems face new threats from climate change. Coldwater fish communities across eastern North America recovering from acidification face projected increases in frequency and severity of hot summers, shifting concern for these communities from surface water acidity to thermal stress. Data from lakes in Adirondack Mountains of New York, however, suggest that changes in water clarity associated with acid deposition recovery may enhance lake stratification leading to shallower thermocline development, thereby increasing coldwater refuge habitat in these lakes during mid-summer. Changes in lake clarity and decreasing thermocline depth that in-turn increase thermal refuge habitat could mitigate against impacts of climate change for thermally sensitive fish species in these lake systems.
