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 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...
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 کاملAllozyme variation in endangered Castanea pumila var. pumila.
Allozyme genetic variation in 12 populations of the endangered Castanea pumila var. pumila (Allegheny chinkapin), sampled across the natural range of the species in the United States, was evaluated using 11 loci from seven enzyme systems. At the species level, the percentage of polymorphic loci (Ps) was 72.7 %, the mean number of alleles per locus (As) was 1.9, the mean number of alleles per po...
متن کاملPlectanocotyle major sp. n. (Monogenea: Plectanocotylidae), a gill parasite of Chelidonichthys obscurus (Teleostei: Triglidae) from the Mediterranean Sea.
Plectanocotyle major sp. n. (Monogenea: Polyopisthocotylea: Plectanocotylidae) is described from Chelidonichthys obscurus (Bloch et Schneider, 1801) collected from the Mediterranean coasts (Tunisia and France). The new species is compared to Plectanocotyle gurnardi collected on Chelidonichthys gurnardus and the only other valid species in the genus Plectanocotyle. The new species differs from P...
