Karyotypic diversity and evolutionary trends in the Neotropical catfish genus Hypostomus Lacépède, 1803 (Teleostei, Siluriformes, Loricariidae)
The family Loricariidae with 813 nominal species is one of the largest fish families of the world. Hypostominae, its more complex subfamily, was recently divided into five tribes. The tribe Hypostomini is composed of a single genus, Hypostomus Lacépède, 1803, which exhibits the largest karyotypic diversity in the family Loricariidae. With the main objective of contributing to a better understan...
متن کاملKaryotypic diversity and speciation in Agrodiaetus butterflies.
That chromosomal rearrangements may play an important role in maintaining postzygotic isolation between well-established species is part of the standard theory of speciation. However, little evidence exists on the role of karyotypic change in speciation itself--in the establishment of reproductive barriers between previously interbreeding populations. The large genus Agrodiaetus (Lepidoptera: L...
متن کاملKaryotypic diversity among three species of the genus Astyanax (Characiformes: Characidae).
The group Incertae sedis within the Characidae family currently includes 88 genera, previously included in the subfamily Tetragonopterinae. Among them is the genus Astyanax comprising a group of species with similar morphology and widely distributed in the Neotropics. Thus, the present study aimed to analyze the karyotype diversity in Astyanax species from different watersheds by conventional G...
متن کاملComparative mapping and rapid karyotypic evolution in the genus helianthus.
Comparative genetic linkage maps provide a powerful tool for the study of karyotypic evolution. We constructed a joint SSR/RAPD genetic linkage map of the Helianthus petiolaris genome and used it, along with an integrated SSR genetic linkage map derived from four independent H. annuus mapping populations, to examine the evolution of genome structure between these two annual sunflower species. T...
متن کاملKaryotypic diversity in the subfamily Eurytominae (Hymenoptera: Eurytomidae).
New data on the karyotype structure of five species of the subfamily Eurytominae are described, including the following species: Eurytoma rosae (2n = 20), E. robusta (n =7, 2n = 14), E. serratulae (n = 6, 2n = 12), E. compressa (2n = 10) and Sycophila biguttata (2n = 18). 2n = 10, 12 and 14 are reported for the first time for the Eurytominae, in which only 2n = 20 and 18 have been previously fo...
