Abstract:Seasonal fluctuation in size structure of a population of Anachis avara at Bear Cut, Miami, Florida occurred similarly each year from fall 1970 through August 1975. This fluctuation was primarily the result of seasonal recruitment of high numbers of juveniles into the population from planktonic veligers. Periodic differences in mortality could have been due to predation by mobile species recurrently present at Bear Cut. The results of temperature and salinity tolerance tests suggest that A. avara was not under physiological stress at Bear Cut over the duration of this work. Shoaling of the Thalassia flat towards the end of this study probably contributed to the drastic decrease in abundance of Anachis avara from December 1973 through June 1975.
