Posidonia oceanica is an endemic seagrass species from the Mediterranean Sea that provides critical ecological services to coastal environments. This distributed Turkish Spanish coast, where its westernmost record was documented in Punta Chullera, Malaga (36°18?36.45?? N, 5°14?54.31?? W). Nevertheless, previous studies suggested distribution even further west, although these populations were ne...

Abstract Aim Species are expected to disperse poleward in response climate change. For species that endemic the high latitudes, this implies many future would face a “no‐where‐to‐go” situation as they currently occupying northernmost portion of continent. Further, because endemism may arise from combination physical barriers, and geological history, persistence require spatial matching multiple...
