1. Genetic and morphological analyses of 50-chromosome spined loaches (Cobitis, Cobitidae, Pisces) from the Black Sea basin that are morphologically similar to C. taenia, with the description of a new species

Cobitis taenia complex, karyotype, nuclear and mtDNA markers, and biogeography
Language:
English
Description:
Karyotyped specimens from three populations of spined loaches, genus Cobitis, that occurred in the Veleka (Bulgaria), Chernaya (Crimean Peninsula) and Southern Bug (Ukraine) Rivers in north-western Pontic region were subjected to enzyme electrophoresis (for 5 loci), comparative morphological studies, and phylogenetic analysis (based on PCR of a 1230 bp fragment of mtDNA and the cytochrome b gene). These studies resulted in the description of loaches from the Crimean Peninsula as a new species Cobitis taurica, while the taxonomic status of populations from the Veleka and S. Bug rivers appeared to be controversial and in need of further investigation.

fish cytogenetics and cytotaxonomy, chromosome banding, multiple nucleolar organizer region (NOR), and leuciscine cyprinids
Language:
English
Description:
The karyotype and major ribosomal sites as revealed by silver staining and CMA3-fl uorescence of Croatian leuciscine cyprinid endemic to Cetina River, Telestes ukliva were studied. The diploid chromosome number was invariably 2n = 50. Karyotype consisted of eight pairs of metacentric, 13 pairs of submetacentric and four pairs subtelocentric chromosomes. The largest chromosome pair of the complement was subtelocentric, which is a characteristic cytotaxonomic marker for all representatives of the cyprinid lineage Leuciscinae. The nucleolar organizer regions (NORs) were detected in the telomeres of two pairs of mediumsized submetacentric chromosomes. Staining with CMA3 revealed four positive signals that corresponded to NOR sites. No heteromorphic sex chromosomes were found. The karyotype pattern of T. ukliva is nearly identical to that found in most other representatives of the Eurasian leuciscine cyprinids, while the multiple NOR phenotype appears to be more derived as opposed to a uniform one NOR-bearing chromosome pair, ubiquitous in this group.

5. Karyotypes of three species of molossid bats (Molossidae, Chiroptera) from India and western Africa

Subject:
karyotype evolution and chromosome banding
Language:
English
Description:
Conventional and G- banded karyotypes are reported for three species of molossid bats from India (Chaerephon plicatus) and Senegal (Ch. pumilus, Mops condylurus). The chromosome diploid number 2n = 48 and the number of chromosomal arms FN = 54 were recorded, similarly as in the previous published reports on karyology of molossid bats from Thailand, East Malaysia, and Africa. A synopsis of karyotypes of bats of the family Molossidae is presented with comments on their chromosomal evolution.

6. Two new Barbus species from the Danube River basin, with redescription of B. petenyi (Teleostei: Cyprinidae)

Type:
article and TEXT
Subject:
taxonomy, nomenclature, neotype, mtDNA, Barbus petenyi, Barbus carpathicus, Barbus balcanicus, and Barbus cyclolepis waleckii
Language:
English
Description:
Three rheophilic species of the western Palaearctic Barbus with adjacent geographic distributions are recognised in the Danube River basin, each diagnosed by a set of unique mitochondrial DNA alleles. Barbus petenyi Heckel, 1852 from the Eastern and Southern Carpathians and from the Stara Planina Mts is redescribed and a neotype is designated. Barbus carpathicus, new species, is distributed in the Western and Eastern Carpathians. Barbus balcanicus, new species, occurs in the Dinaric and Western Stara Planina Mts. The three species are morphologically similar to each other but B. balcanicus can be distinguished by subtle differences in the snout shape and body and fin colour pattern. As evident from genetic data the name B. cyclolepis waleckii Rolik, 1970 was proposed for the hybrids between B. barbus and B. carpathicus and cannot be used as valid.
