Stereological analysis of liver tissue excised from mature female Rana pipiens starved for 59 days and from a fed control group was conducted both at the light and electron microscopy levels. Average cellular volume decreased by more than a factor of

A natural phytoplankton assemblage from Grand Traverse Bay, Lake Michigan, was treated with factorial enrichments of nitrate and phosphorus, with maintained nutrient concentrations ranging from 5 to 60 µg total soluble phosphorus liter−1 and 0.225

Fibers observed within the cisternae of endoplasmic reticulum of liver cells of Rana pipiens are described. Fibers were observed only in animals subjected to starvation, but the frequency of fiber occurrence was found to vary widely from animal to an
