Abstract
    Monhystera denticulata, a free-living nematode present in the `aufwuchs' assemblages of several marine macrophytes located in North Sea Harbor, Southampton, New York, was isolated from Zostera marina and established in laboratory culture in order to study the influences of temperature and salinity on its life history. Under experimental conditions, M. Denticulata has a generation time (measured as the time elapsing between the first egg depositions of consecutive generations) of 10-12 days at 25 degree C and 26 ppt, which represent optimal growth conditions in the laboratory. The organism has a generation time of 20 days at 25 degree C and 13 ppt, 17 days at 25 degree C and 39 ppt, 18 days at 15 degree C and 26 ppt, 36 days at 15 degree C and 13 ppt and 34 days at 15 degree C and 39 ppt. As conditions vary from the optimum of 25 degree C and 26 ppt, a decrease in temperature of 10 degree C and an increase or decrease in salinity of 13 ppt results in a doubling of the generation time. At 5 degree C the generation time is similar to 180-197 days. Assuming optimum conditions and average generation time, similar to 15 generations of M. Denticulata could occur in North Sea Harbor during the year. The number of generations occurring in reality is probably less, however, due to the fact that the females deposit their eggs over a period of several days.
