| rrs1-like sequences of water frogs from central europe and around the aegean sea: chromosomal organization, evolution, possible function. | rrs1-like sequences of water frogs (genus pelophylax) display varied genomic organization, whereas the centromeric hybridization pattern reveals species-specific differences. using fluorescent in situ hybridization, pelophylax cf. bedriagae, pelophylax kurtmuelleri, and pelophylax ridibundus showed a hybridization signal at centromeres of chromosomes 1-5, but in p. kurtmuelleri the medium-small chromosome labeled was 10 rather than 8. pelophylax cretensis had almost 16 of 26 centromeres labeled, ... | 2011 | 21424546 |
| a cryptic invasion within an invasion and widespread introgression in the european water frog complex: consequences of uncontrolled commercial trade and weak international legislation. | in western europe, many pond owners introduce amphibians for ornamental purposes. although indigenous amphibians are legally protected in most european countries, retailers are circumventing national and international legislation by selling exotic nonprotected sibling species. we investigated to what extent non-native species of the european water frog complex (genus pelophylax) have become established in belgium, using morphological, mitochondrial and nuclear genetic markers. a survey of 87 sam ... | 2008 | 19017263 |
