01Narrative

Alosa caspia is a species of clupeid fish, one of the species of shad (genus Alosa) endemic to the Caspian Sea basin.Freyhof, J. & Kottelat, M. 2008. Alosa caspia. The IUCN Red List of Threatened Species. Version 2014.3. Downloaded on 18 April 2015. FishBase treats separately three subspecies from the Caspian: Caspian shad, Alosa caspia caspia (Eichwald, 1838) Enzeli shad, Alosa caspia knipowitschi (Iljin, 1927) Astrabad shad, Alosa caspia persica (Iljin, 1927) Previously the taxonomic circumscription and geographic range of A. caspia have been broader, encompassing also the Sea of Azov and Black Sea basins.Peter J.P. Whitehead (1985) Subfamily Alosinae In: Clupeoid Fishes of the World - an annotated and illustrated catalog of the herrings, sardines, pilchards, sprats, shads, anchovies and wolf-herrings. FAO Fisheries Synopsis No. 125, Volume 7, Part 1. Rome: UNDP FAO.A. caspia (Eichwald,1838) - каспийско-черноморский пузанок Позвоночные животные России. sevin.ru Up to ten subspecies were recognised; these included forms now classified as Alosa tanaica (and its synonyms) and even the Balkan freshwater endemics Alosa macedonica and Alosa vistonica.

07Deep time~0.39 Ma lineage

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin0.39 Ma TimeTree

When this lineage existed

How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.
