Abstract

Tottino Ponds is an artificial wetland created in the middle of agricultural fields, near Monterey Bay, and filled with recycled waste water. The site consists of four 25-meter square ponds. A study was conducted between October 2000 and April 2001 on the planktonic organisms living in the ponds. A series of one-liter samples were taken on four different dates. The samples were preserved and sorted. The samples contained a total of 121,526 organisms ranging in size from rotifers to a tadpole (Pseudacris). A measure of chlorophyll concentration was taken at the beginning and end of the study. The results showed that copepod, rotifer, and cladoceran abundance varied with time and remained constant from pond to pond. There was a negative correlation between cladoceran and chlorophyll abundance. The diversity of Tottino ponds throughout the survey, using Simpson's diversity index (1-I), was 0.51.
