Open AccessDistribution and host range of a highly invasive parasitic copepod
The parasitic copepod Neoergasilus japonicus (Ergasilidae), native to East Asia, has spread rapidly around the world over the past half-century and now represents a clear example of successful parasitic invader. ...

Open AccessReproduction-associated pathways in females of gibel carp (Carassius gibelio) shed light on the molecular mechanisms of the coexistence of asexual and sexual reproduction
Gibel carp (Carassius gibelio) is a cyprinid fish that originated in eastern Eurasia and is considered as invasive in European freshwater ecosystems. The populations of gibel carp in Europe are mostly composed of...

Open AccessMonogeneans in intergeneric hybrids of leuciscid fish: Is parasite infection driven by hybrid heterosis, genetic incompatibilities, or host-parasite coevolutionary interactions?
Several hypotheses have been proposed to explain parasite infection in parental species and their hybrids. Hybrid heterosis is generally applied to explain the advantage for F1 generations of hybrids exhibitin...

Open AccessDiversity of MHC IIB genes and parasitism in hybrids of evolutionarily divergent cyprinoid species indicate heterosis advantage
The genes of the major histocompatibility complex (MHC) are an essential component of the vertebrate immune system and MHC genotypes may determine individual susceptibility to parasite infection. In the wild, ...

Open AccessDistribution of host-specific parasites in hybrids of phylogenetically related fish: the effects of genotype frequency and maternal ancestry?
Host specificity is one of the outputs of the coevolution between parasites and their associated hosts. Several scenarios have been proposed to explain the pattern of parasite distribution in parental and hybr...

Application of the alizarin red S mass marking technique and its detection in stocked asp (Leuciscus aspius)
Alizarin Red S marking and detection was tested on asp (Leuciscus aspius Linnaeus, 1758) in an experimental pool followed by a mark-recapture experiment in the field. Placing the asp in a 0.15 g L−1 solution for ...

Open AccessPhysiological and condition-related traits in the gynogenetic-sexual Carassius auratus complex: different investments promoting the coexistence of two reproductive forms?
Carassius auratus complex is an extraordinary species complex including the diploid and polyploid forms exhibiting asexual and sexual reproduction modes. The coexistence of both forms ...

Open AccessMHC genes and parasitism in Carassius gibelio, a diploid-triploid fish species with dual reproduction strategies
The gibel carp is a fish species with dual reproduction modes, gynogenesis and sexual reproduction, coexisting in mixed diploid-polyploid populations. Following the Red Queen (RQ) assumption, asexual organisms...

Open AccessDoes interspecies hybridization affect the host specificity of parasites in cyprinid fish?
Host specificity varies among parasite species. Some parasites are strictly host-specific, others show a specificity for congeneric or non-congeneric phylogenetically related host species, whilst some others a...

The effect of ploidy and temporal changes in the biochemical profile of gibel carp (Carassius gibelio): a cyprinid fish species with dual reproductive strategies
The basic biochemical profile of gibel carp (Carassius gibelio), diploid–triploid cyprinid species complex with dual reproduction modes, was investigated. The aim of the study was to test for the effect of fish g...
