| Popis: | Knowledge of short- and long-term reproductive patterns is basic for numerous types of biological, ecological, evolutionary, and fisheries studies. Using data from more than 22 y of sampling commercially valuable stone crabs (genus Menippe (Say, 1819)) in Tampa Bay, FL, we defined size-specific interannual and intra-annual patterns in ovarian development and spawning; explored relationships between the molting cycle and intra-annual patterns; and identified the influence of water temperature on those interrelationships. Frequency of gravid females (frequency-gravid) seemed to shift in multiyear cycles but frequency of ovigerous females (frequency-ovigerous) did not. Frequency-gravid and frequency-ovigerous increased with size class except in the largest females. Interannual variation in frequency-ovigerous was the product of multiple patterns differing principally between size-class-70 and -80 females and size-class-90 and -100+ females. Ovarian development, spawning, and molting in females of si... |
