| Abstract | Different environments can affect the reproduction on marine organisms. Along the coastline, wave action is seemedto be the strongest stress factor that influences seaweed populations. Seaweed can grow under two different conditions ofwave action. The life phases, reproduction and quantity of reproductive cells were recorded for each individual in Padinaboryana. Both populations had the highest percentage of reproduction in May and dominance of sporophytes. The numberof spore and time of production were different at the two sites. Increasing temperature, day length and emersion timeenhanced desiccation and high temperature influencing the spore production and maturation of life phases at both locations.More wave exposure decreased the number of reductive cell and changed the pattern of production time in differencescenarios. Energy allocations can play an important role for explaining the cycle of reproduction time in a year on differentpopulations under different wave exposure. |
