Phylogeography of Aphanius fasciatus (Osteichthyes: Aphaniidae) in the Mediterranean Sea, with a focus on its conservation in Cyprus

Langeneck, Joachim & Englezou, Christopher. (2021). Hydrobiologia. https://link.springer.com/article/10.1007/s10750-021-04627-5. AbstractAphanius fasciatus is a small fish occurring in Mediterranean brackish environments. In Cyprus it is known from three localities separated by long stretches of coast.

A comparison with the other available data showed that Cyprus populations represent a distinct lineage. The other lineages are concentrated in a relatively small area between the Strait of Sicily and the Western…

There are still no sea ports listed and only Edinburgh, Gatwick, Heathrow and Manchester amongst the…
