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...

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, little is known about the species' population structure or if different ecotypes contributed to this outbreak. Specimens (n = 178) were sampled from 25 locations from six regions spanning 1.9 million km2. A fragment of the mitochondrial cytochrome b gene and control region was used to assess population structure and genetic diversity. Both loci showed high haplotype diversity (Hd) and low nucleotide diversity (π) over all sampled locations. A genetic signature of population expansion was evident through mismatch distributions and tests for recent population expansion (Fu's Fs, Tajima's D and R2). Effective population size analyses (Bayesian skyline plot) suggest an expansion 50-100 thousand years before present.
