摘要

The rockly intertidal zone has the potential to be one of the harshest environments for free-spawning organisms, but empirical data on fertilization success are scarce. Here, I report on an intertidal, solitary ascidian, Pyura stolonifera, which was observed to spawn at lot tide. At a scale likely to be most important to gametes(metres, duration of tide), approximately 30/100 of individuals in the population were spawning synchronously. Spawned gametes remained in a viscous matrix and this appeared to minimise their dilution. Fertilization success varied greatly among individuals(0 to 92/100)and was related to the distance to the nearest neighbouring spawner.
