Nitrogen Saturation and Retention in Forested Watersheds of the Catskill Mountains, New York
The Catskill Mountains of southeastern New York receive relatively high rates of atmospheric N deposition, and NO3 concentrations in some streams have increased dramatically since the late 1960s. We measured the chemistry of 39 firstand second-order streams with forested watersheds to determine the variability of nitrogen concentrations within the Catskill Mountain area. We found that some stre...

متن کاملBiotic and abiotic immobilization of ammonium, nitrite, and nitrate in soils developed under different tree species in the Catskill Mountains, New York, USA
Nitrogen retention in soil organic matter (SOM) is a key process influencing the accumulation and loss of N in forest ecosystems, but the rates and mechanisms of inorganic N retention in soils are not well understood. The primary objectives of this study were to compare ammonium (NH4 1 ), nitrite (NO2 ), and nitrate (NO3 ) immobilization among soils developed under different tree species in the...
متن کاملEffect of stream acidification and inorganic aluminum on mortality of brook trout (Salvelinus fontinalis) in the Catskill Mountains, New York
Juvenile brook trout (Salvelinus fontinalis) were exposed in cages to fluctuating chemical conditions in four Catskill Mountain streams during the spring and fall of 1989 and the spring of 1990. Specific chemical constituents and characteristics of acidic episodes that correlated with increased fish mortality were identified. Mortality increased during acidic episodes in one poorly buffered str...
