What can goby otolith morphology tell us?

Popis výsledku v původním jazyce

This case study deals with otoliths of the Oxudercidae, which, together with the Gobiidae, encompasses the 5-branchiostegal-rayed gobiiforms. The objective was to determine whether the five lineages of the Oxudercidae, and individual species of the European Pomatoschistus lineage, could be distinguished based on the quantification of otolith variations. The data set comprises otoliths from a total of 84 specimens belonging to 20 recent species, which represent all five lineages of the Oxudercidae (Mugilogobius, Acanthogobius, Pomatoschistus, Stenogobius, Periophthalmus), and five fossil otoliths of +Pomatoschistus sp. (sensu Brzobohatý, 1994). Ten measurements were taken on each otolith and 23 otolith variables were computed and used for univariate and multivariate analyses. The results indicate that otolith morphometry (i) is capable of identifying the Pomatoschistus and Periophthalmus lineages among the Oxudercidae, but is of limited use in the separation of the other three lineages; (ii) can reliably distinguish the sand gobies (a distinct clade within the Pomatoschistus lineage) from other members of the Pomatoschistus lineage; and (iii) supports a previous assignment of fossil otoliths to +Pomatoschistus sp. as an ancient genus of the sand gobies. With its middle Miocene age (15 m.y. ago), +Pomatoschistus sp. represents the oldest record of a sand goby species to date. We discuss possible relationships between distinct otolith morphologies, biogeographic distribution and lifestyles for Pomatoschistus and the Periophthalmus lineage, and also for the sand gobies. We conclude that otolith morphology, combined with morphometry, can be considered as an autapomorphy for an individual species from the studied groups. In addition, it also appears to contain a phylogenetic signal, but more work is needed to evaluate this fully.
