Phylogeography and Population Genetic Analyses in the Iberian Toothcarp (Aphanius iberus Valenciennes, 1846) at Different Time Scales

Secondary freshwater fish species inhabiting fluctuating and extreme environments are susceptible to changes in dispersion, effective population size, and genetic structure. The Iberian toothcarp Aphanius iberus is an endemic cyprinodontid of the Iberian Peninsula restricted to brackish water of salt marshes and coastal lagoons on the eastern Spanish Mediterranean coast. In this study, we analyzed

Three new species of algae-scraping cyprinid from Tigris River drainage in Iran (Teleostei: Cyprinidae)

Traditionally small-scale populations of Capoeta in the Tigris River drainage are identified as Capoeta damascina. The recent finding revealed that some populations of small-scaled C. damascina species group are not identified as any described species. We examined these populations and the results showed that there are pronounced differences between them in morphological and molecular characters.
