TEMPORAL SHIFTS IN THE DOC, UV PENETRATION, AND ZOOPLANKTON POPULATIONS IN AUTUMN TEMPORARY PONDS

Temporary ponds are an important part of many woodland ecosystems. Previous studies have focused on the properties of the pond from ice out through the spring of the year but have neglected the factors that set the foundation for springtime zooplankton population levels. Nineteen forestland temporary pools were sampled for their pre-winter-freeze properties. Although most pools were dry at autumn equinox, the ponds ranged in size from 6-17m in diameter during the wet period of the year. Dissolved organic carbon (DOC) values ranged between 1.3 and 17.0 mg/L. UV absorbance at 320nm ranged between 0.3 and 11.2 and was positively correlated with DOC. UV attenuation depths (1% of surface) were estimated at 0.28-11.8m although the ponds typically were less than a meter deep.
