Before revision:  In the case of sedentary marine populations, connectivity stems not only from the stochastic nature of the physical environment that affects early-life stages dispersal, but also by the spawning stock attributes that affect reproductive output (e.g., passive eggs and larvae) and its survivorship, constituting the so-called spatial reproductive system.
