ABSTRACT
In order to review the existing literature we conducted a literature search in both Web of Science and Zoological Record for the following two search string in the “Topic” fi elds: “Gobioidei OR Goby OR Gobies OR Eleotridae OR Butinae OR Eleotrinae OR Gobiidae OR Amblyopinae OR Gobiinae OR Gobionellinae OR Oxudercinae OR Sicydiinae OR Kraemeriidae OR Microdesmidae OR Odontobutidae OR Ptereleotridae OR Rhyacichthyidae OR Schindleriidae OR Xenisthmidae” AND “systematic OR phylogeny OR phylogeography OR evolution OR relationship OR gene OR DNA OR sequence OR gene fl ow OR microsatellite OR population genetic OR population structure OR allozyme OR isozyme”. The search conducted on 29 April, 2009 retrieved 511 references in the Web of Science and 193 references in Zoological Record. A total of 69 duplicates were identified reducing the total number of references from 704 to 635. Aft er manually fi ltering the remaining references a total of 132 were kept that can be broadly classifi ed as dealing with molecular systematics of gobioids. Note, that articles that deal with broader systematic issues and that included some gobioid taxa could not be detected with the search criterion used. Table 1.2.5 summarizes which molecular markers are most commonly used in molecular systematic studies of gobioids with allozymes/isozymes (38 studies), mitochondrial cob gene (32 studies), and microsatellites (23 studies) ranked in the top three.
