Haplotype diversity and phylogenetic relationships among the Iberian barbels (Barbus, Cyprinidae) reveal two evolutionary lineages.
The phylogenetic relationships and haplotype diversity of all Iberian barbels were examined by analyzing the complete mitochondrial cytochrome b gene sequence (1141 bp) of 72 specimens from 59 Iberian localities. Phylogenetic findings demonstrated a clear distinction between two mitochondrial lineages and confirmed the existence of two previously considered subgenera: Barbus and Luciobarbus: Th...
متن کاملOn the Two Species Asymmetric Exclusion Process with Semi-permeable Boundaries
We investigate the structure of the nonequilibrium stationary state (NESS) of a system of first and second class particles, as well as vacancies (holes), on L sites of a one-dimensional lattice in contact with first class particle reservoirs at the boundary sites; these particles can enter at site 1, when it is vacant, with rate α, and exit from site L with rate β. Second class particles can ne...
متن کاملTaxonomic revision of the genus Carasobarbus Karaman, 1971 (Actinopterygii, Cyprinidae)
Representatives of the fish genus Carasobarbus Karaman, 1971 (Actinopterygii: Cyprinidae) from the Middle East and North Africa were previously placed in 14 different genus-group taxa (Barbellion, Barbus, Barynotus, Capoeta, Carasobarbus, Cyclocheilichthys, Kosswigobarbus, Labeobarbus, Luciobarbus, Pseudotor, Puntius, Systomus, Tor and Varicorhinus). The generic assignment of several species ch...
متن کاملRecent origin and semi-permeable species boundaries in the scleractinian coral genus Stylophora from the Red Sea
Reticulate evolution, introgressive hybridisation, and phenotypic plasticity have been documented in scleractinian corals and have challenged our ability to interpret speciation processes. Stylophora is a key model system in coral biology and physiology, but genetic analyses have revealed that cryptic lineages concealed by morphological stasis exist in the Stylophora pistillata species complex....
متن کاملEnteroendocrine APUD cells in the digestive tract of larval Barbus conchonius (Teleostei, Cyprinidae).
The development of Barbus conchonius is described with special attention to the differentiation of the gut. Amine precursor uptake and decarboxylation (APUD) are present in enteroendocrine cells during development, whereas these processes are lacking in adult specimens. The first APUD cells originate on the fourth day of development in the anterior part of the gut and on the fifth day in the ca...
