Genomic Porosity between Invasive Chondrostoma nasus and Endangered Endemic Parachondrostoma toxostoma (Cyprinidae): The Evolution of MHC IIB Genes
Two cyprinid species, Parachondrostoma toxostoma, an endemic threatened species, and Chondrostoma nasus, an invasive species, live in sympatry in southern France and form two sympatric zones where the presence of intergeneric hybrids is reported. To estimate the potential threat to endemic species linked to the introduction of invasive species, we focused on the DAB genes (functional MHC IIB ge...
متن کاملReproductive biology of lotak, Cyprinion macrostomum Heckel, 1843 (Pisces: Cyprinidae), from the Tigris River drainage
Some reproduction aspects of the "doctor fish", Cyprinion macrostomum, were examined for the first time from the Tigris River drainage. A total of 316 specimens were caught from Gamasiab River in western Iran, at monthly intervals throughout the year from January to December 2013. Age, sex ratio, fecundity, oocytes diameter, gonado‑somatic (GSI), modified gonado‑somatic (MGSI) and Dobriyal (DI)...

متن کاملComparative osteology of Chondrostoma orientale and C. nasus
Comparison of morphological structures is a key element in evolutionary biology and taxonomy, as well as in the studies concerning variation and biodiversity either at interspecific or intraspecific levels. This study aimed to compare the bony structures of Chondrostoma orientale and C. nasus. For this purpose, three specimens of C. orientale from the Kor River (passing through Iran), and five ...
متن کاملPebble nest microhabitats of Semotilus species (Pisces: Cyprinidae)
The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deep...
