When an ‘invasive’ fish species fails to invade! Example of the topmouth gudgeon Pseudorasbora parva
A major problem in evaluating biological invasions is the lack of information on failed non-native species introductions, with invasiveness determined purely on establishment successes. This is the case of topmouth gudgeon Pseudorasbora parva, an Asiatic cyprinid fish that now occurs throughout most of Europe and is said to be highly invasive. Although the species has established itself in many...
متن کاملMorphological variability of the Asiatic cyprinid, topmouth gudgeon Pseudorasbora parva, in its introduced European range.
To assess the spatial variability in external morphology of non-native populations of topmouth gudgeon Pseudorasbora parva within an ontogenetic context, triple regression analysis (distance-based measurements) was applied to data from eight European populations (two Slovak, four Romanian, one English and one French). The data from Slovakia were also subjected to geometrical analysis (co-ordina...
متن کاملDistribution of the topmouth gudgeon, Pseudorasbora parva (Cyprinidae:Gobioninae) in Lake Eğirdir,Turkey
Topmouth gudgeon, Pseudorasbora parva was firstly recorded in Europe in southern Romania and Albania. This species was firstly determined from the Thrace region of Turkey in 1984 in the River Meriç. In this research, samples collected from four different stations between March 2010 and June 2011. A total of 81 P. parva individuals were caught by using drift-nets with a mesh-size of 10 mm, and ...
متن کاملHigh prevalence of the parasite Sphaerothecum destruens in the invasive topmouth gudgeon Pseudorasbora parva in the Netherlands, a potential threat to native freshwater fish
The prevalence of Sphaerothecum destruens, a pathogenic parasite, was studied in two wild populations of topmouth gudgeon (Pseudorasbora parva), an invasive freshwater fish non-native to the Netherlands. Using genetic markers and sequencing of the 18S rRNA gene, we showed the prevalence of this parasite to be 67 to 74%. Phylogenetic analysis demonstrated a high similarity with known sequences o...
متن کاملIsolation and characterization of 19 polymorphic microsatellite loci from the topmouth gudgeon, Pseudorasbora parva.
The Asiatic topmouth gudgeon, Pseudorasbora parva, is recognized as one of the most invasive fish species in many countries outside of Asia. We isolated and characterized 19 microsatellite loci from P. parva. The polymorphism of these 19 loci was tested on 40 individuals of P. parva sampled from a wild population located in Ezhou, Hubei province of China. The loci had 5 to 11 alleles, with a me...
