    Abstract Bergmann's rule predicts that organisms at higher latitudes are larger than ones at lower latitudes. Here, we examine the body size pattern of the Atlantic marsh fiddler crab,Minucapugnax (formerly Uca pugnax), from salt marshes on the east coast of the United States across 12 degrees of latitude. We found thatM. pugnaxfollowed Bergmann's rule and that, on average, crab carapace width increased by 0.5 mm per degree of latitude.Minuca pugnaxbody size also followed the temperature–size rule with body size inversely related to mean water temperature. Because an organism's size influences its impact on an ecosystem, andM. pugnaxis an ecosystem engineer that affects marsh functioning, the larger crabs at higher latitudes may have greater per‐capita impacts on salt marshes than the smaller crabs at lower latitudes.
