Phylogeography of the snake pipefish, Entelurus aequoreus (Family: Syngnathidae) in the northeastern Atlantic Ocean
The snake pipefish, Entelurus aequoreus, is a widespread marine species occurring in pelagic and coastal environments in the northeastern Atlantic Ocean. Recently, the snake pipefish underwent a short-lived, yet substantial, increase in abundance and range expansion into arctic waters. However, litt...
