Unnoticed introductions, a silent threat for biodiversity: island endemic <i>Ladigesocypris ghigii</i> (Actinopterygii, Leuciscidae) translocated to continental Greece Open
Morphological similarity between an intruder and a native species can hinder the detection of the intruder. The undetected non-native species will thus have more time to affect the local ecosystem and spread. This paper describes an instan…

A new perspective on the molecular dating of the brown trout complex with an extended phylogeographic information on the species in Serbia Open
To elucidate the historical biogeography of a species, the patterns of population divergence must be understood, and the evolutionary history of the species must be accurately known. For brown trout ( Salmo trutta complex), estimating dive…
