七个纬度分离的贻贝Myti种群的繁殖条件！us edu！使用组织学分析和体视学确定了美国东海岸的最大直径。不同种群配子发生周期各阶段的时间差异没有任何明显的纬度趋势。两个种群在同一纬度的长岛，N。Y.有最大的时间差异，观察配子发生周期，夏季繁殖高峰期由3个月的间隔。这两个栖息地之间的水温制度没有差异，因此配子发育的速率不是温度的恒定函数。所观察到的配子发生周期的差异是由于时间和数量的差异，在贻贝的食物供应的能量含量的栖息地。
The reproductive condition of seven latitudinally separated populations of the mussel Myti!us edu!is on the east coast of the United States was determined using histological analysis and stereology. Differences in the timing of various phases of the gametogenic cycle among populations did not have any discernible latitudinal trend. Two populations at the same latitude on Long Island, N. Y. had the greatest temporal differences observed in gametogenic cycle, with summer reproduction maxima separated by a 3-month interval. There was no difference in the water temperature regime between these two habitats and thus the rate of gametogenic development was not a constant function of temperature. The observed differences in the gametogenic cycle were attributed to temporal and quantitative differences between habitats in the energy content of the mussel's food supply.
