The patterns and processes linked to the host specificity of parasites represent one central themes in study host-parasite interactions. We investigated evolution determinants gill monogeneans Cichlidogyrus Scutogyrus species parasitizing African freshwater fish Cichlidae. analyzed (1) link between parasite phylogeny, (2) potential morphometric correlates (i.e. body size morphometrics attachment apparatus), (3) following hypothesis ecological specialization on predictable resources longevity...
Dactylogyrus species (Dactylogyridae: Monogenea) are a group of monogenean gill parasites that highly specific to freshwater fish the family Cyprinidae. were sampled from 19 cyprinids and one percid collected in Europe. Using partial 18S rDNA ITS1 sequences, phylogeny 51 was reconstructed investigate patterns parasite speciation diversification. Three main lineages recognized all phylogenetic trees, is, analysis alone combined 18SrDNA ITS1. The first lineage associates Cyprinus carpio...
Abstract Patterns and likely processes connected with evolution of host specificity in congeneric monogeneans parasitizing fish species the Cyprinidae were investigated. A total 51 Dactylogyrus was included. We investigated (1) link between parasite phylogeny; (2) morphometric correlates specificity, body size, variables attachment organs important for specificity; (3) morphological adaptation, that is, organ; (4) determinants following hypothesis specialization on more predictable resources...
Abstract Background The basic function of the immune system is to protect an organism against infection in order minimize fitness costs being infected. According life-history theory, energy resources are a trade-off between costly demands immunity and other physiological demands. Concerning fish, both physiology influenced by seasonal changes (i.e. temporal variation) associated abiotic factors (such as primarily water temperature) interactions with pathogens parasites. In this study, we...
The goals of this paper were to investigate phylogenetic and evolutionary patterns cichlid fish from West Africa their Cichlidogyrus Scutogyrus monogenean parasites, uncover the presence host-parasite cospeciation assess level morphological adaptation in parasites. This required following steps, each one representing specific objectives paper: (1) build trees for species based on ribosomal DNA sequences, (2) relationships within African analysis mitochondrial cytochrome b (3) cophylogenetic...
Host specificity in parasites represents the extent to which a parasite's distribution is limited certain host species. Considering host-specific of primarily freshwater fish (such as gill monogeneans), their biogeographical essentially influenced by both evolutionary and ecological processes. Due capacity for historical dispersion fish, specific coevolving may, through host-parasite associations, at least partially reveal routes (or contacts) We used Dactylogyrus spp., cyprinid infer...
Beyond morphology: cryptic diversity in nine new Gyrodactylus species (Monogenea: Gyrodactylidae) associated with northwest African barbels (Cyprinidae) and remarks on nyingiae Shigoley, Rahmouni, Louizi, Pariselle Vanhove, 2023
Phylogenetic analyses based on the partial large subunit rDNA (LSU) sequences of polyonchoinean monogeneans belonging to Dactylogyridea and Monocotylidea were generated investigate relationships among various subfamilies Dactylogyridae sensu Kritsky & Boeger, 1989. Monophyly was supported by all performed. Status Ancyrocephalidae Bychowsky Nagibina, 1978 Ancyrocephalinae 1989 revised present data. All phylogenetic indicated polyphyletic origins Ancyrocephalinae. Freshwater species...
Host specificity varies among parasite species. Some parasites are strictly host-specific, others show a for congeneric or non-congeneric phylogenetically related host species, whilst some non-specific (generalists). Two cyprinids, Cyprinus carpio and Carassius gibelio, plus their respective hybrids were investigated metazoan parasites. The aim of this study was to analyze whether interspecies hybridization affects specificity. different degrees within phylogenetic framework taken into...
Parasites exhibiting a high degree of host specificity are expected to be intimately associated with their hosts. Therefore, the evolution host-specific parasites is at least partially shaped by evolutionary history and distribution such Gill ectoparasites Dactylogyrus (Monogenea) specific cyprinid fish. In present study, we investigated 47 species from Balkan Peninsula, Mediteranean region highest diversity in Europe, central European cyprinids. Phylogenetic analyses revealed four...
Assuming that differences or similarities in morphology among congeneric parasite species living the same habitat are not a random pattern, several hypotheses explaining morphological were tested: (i) reproductive isolation, (ii) niche restriction resulting from competition, and (iii) specialization. Congeneric monogenean (platyhelminth) ectoparasites parasitizing gills of one host used as an ecological model. Morphometric distances attachment organ morphometric copulatory between pairs...
