                         affecting the global distribution of mangroves and saltmarshes. 
                         The replacement of saltmarshes by mangroves is expected due to 
                         global warming, reflecting the long-term natural trends in the 
                         Holocene and anthropogenic impacts since the 20th century. We 
                         documented the Holocene history of wetlands dynamics in the boreal 
                         limits of the American mangroves, located at Bay Champagne, 
                         Louisiana (USA), by integrating sedimentological, palynological, 
                         geochemical (\δ13C and C\N), X-ray fluorescence (XRF) data, 
                         and radiocarbon chronology from two sediment cores. The results 
                         indicated a freshwater lake environment with herbs and wetland 
                         ferns, as well as C3 terrestrial plants, between ~8100 and ~6500 
                         cal yr BP. This environment shifted into a lagoon and saltmarshes 
                         having sedimentary organic matter sourced from marine algae 
                         between ~6500 and ~1500 cal yr BP. In the final stage, washover 
                         sediments were deposited in the lagoon during the last ~1500 cal 
                         yr BP. Despite the increased marine influence over the last ~6500 
                         cal yr BP, mangrove pollen were not recorded between ~8100 and 
                         ~1500 cal yr BP, suggesting that mangroves were absent in the 
                         study area during that time interval. Historical evidence and a 
                         comparative analysis of our multi-proxy data with other mangrove 
                         studies from the Gulf of Mexico, Caribbean, and eastern South 
                         America revealed a gradual mangrove expansion from tropical to 
                         subtropical coasts of South and North America during the mid-late 
                         Holocene. The mangrove colonies at their current boreal (29° 
                         09\′ N) and austral (28° 29\′ S) limits were 
                         established in the early and mid-20th century, respectively. This 
                         mangrove dynamics on a continental scale suggests that the 
                         poleward mangrove migration was likely caused by the warming 
                         climate during the Holocene. More importantly, the industrial-era 
                         warming has likely accelerated the mangrove expansion, but it was 
                         not the primary force that drove the mangrove migration into 
                         temperate zones.",
