Can the timing and duration of planktonic larval development contribute to invasion success? A case study comparing range expansion in the European green crab, Carcinus maenas, and the native lined shore crab, Pachygrapsus crassipes, in the northeast Pacific

Major El Niño events and oceanic heat waves are linked to the range expansion of many marine species. For the shores of the northeast Pacific, we compared range expansion in the European green crab, Carcinus maenas , which was introduced to San Francisco Bay prior to 1990, to that of the native line...

Description
Summary:Major El Niño events and oceanic heat waves are linked to the range expansion of many marine species. For the shores of the northeast Pacific, we compared range expansion in the European green crab, Carcinus maenas , which was introduced to San Francisco Bay prior to 1990, to that of the native lined-shore crab, Pachygrapsus crassipes. The initial northern range limit of these species was central California and southern Oregon, respectively. Both species increased their northern range along the open coast to northern Oregon, Washington and Vancouver Island after strong El Niño events. C. maenas , however, in just a matter of decades, successfully established populations in estuaries from Oregon to inlets on the west coast of Vancouver Island, and possibly also in the Salish Sea, while P. crassipes, never has in recorded history. We hypothesize that this difference in invasion success is due to the shorter larval duration of C. maenas ,
