The reproductive biology of Gnetum latifolium Blume studied in four different forest sites of Tamil Nadu. G. latifolium reported to have dioecious plants with less number male population in all the selected areas. Entamophilous cues observed with common anaemophily and pollinator may be flies. Pollination dropsare also reported in young ovules. The seed maturation and germination frequency observed with very low frequency in all the selected population whereas in high number of abortive ovules reported in Western Ghats.

Annual Reproductive Cycle

The commercial sea cucumber Parastichopus californicus (Stimpson) has an annual reproductive cycle, with spawning occurring in the late spring through summer within the inland waters of southwestern British Columbia, Canada. The sexes are separate and occur at a 1:1 ratio within the population studied. Ovarian and testicular tubules regenerate and proliferate preceding the spawning season each year. Spawning is partially synchronous and may be mediated by an increase in the intensity and duration of insolation.
