Biogeographical patterns and areas of endemism for the Magellan region based on the distribution of crustacean species (Amphipoda, Copepoda, and Euphausiacea)

The study identifies three main areas of endemism in the Magellan region—Chiloé, the Atlantic coast, and Fueguia—using the distribution of Amphipoda, Copepoda, and Euphausiacea. The findings provide new biogeographic data for several marine protected areas at the southern tip of South America, including Burdwood Bank, Yaganes, and the Diego Ramírez-Drake Passage.

• The study identified three primary areas of endemism (AEs) in the Magellan region: Chiloé, the Atlantic coast, and Fueguia. Within these, smaller specific areas were recognized, including the San Jorge Gulf and Cape Blanco within the Atlantic coast AE, and the Channels and Fjords, Malvinas/Falklands, Burdwood Bank, and South-West Atlantic transition area within the Fueguia AE. The findings for the Atlantic coast and Fueguia do not strictly align with provinces previously defined in existing literature.
• The research provides new biogeographic insights for zones that are currently designated as marine protected areas at the southern tip of South America, specifically naming Burdwood Bank, Yaganes, and the Diego Ramírez-Drake Passage.
