| Notes | A planktonic copepod, Pseudiaptomus inopinus, native to the shores of China, Korea and Japan, has invaded the estuaries of the Pacific Northwest. This article addresses the question of how the species spread in the northwestern Pacific. Did it spread by migration from one estuary to its neighbors? Did it spread from a migrant pool offshore? Or did it spread by irregular random pulses? The authors used genetics to answer this question and concluded that a pulsed model of spread by ballast water at irregular intervals fits the data. “The stochastic pattern of long-range dispersal observed in P. inopus suggests that planktonic invaders may spread across estuarine systems in a highly unpredictable manner.” (p.1592) |
