Age Determination and Climate Change

Given that biology of the scallop is temperature-sensitive it is a useful barometer of climate change impacts on Atlantic shelf-dwelling species. Growth signatures in the valves of the scallops provide tools to reconstruct both demographics of the populations, thus providing descriptions of temporal and spatial recruitment in addition to documenting trends that may be related to climate change impacts associated with the gradual warming of the southern Mid Atlantic Bight.
