COAD Canadian Museum of Nature, Ottawa, Ontario, K1P 6P4 Canada. Email: [email protected] Abstract: The land-locked country of Afghanistan has a restricted but relatively diverse ichthyofauna comprising 85 species in 10 families. The fauna is dominated by Cyprinidae (50 species) and other Ostariophysans (28 species). Eight species are endemics to Afghanistan within its political boundaries. There are three principal drainage basins: the endorheic Amu Darya draining to the Aral Sea with 29 species, the endorheic Helmand River basin draining to the Sistan terminal lakes on the Iranian border with 22 species, and the Kabul River basin draining to the Indus River with 44 species. Keywords: Biodiversity, Afghanistan, Distribution. Introduction Checklist of native fishes of Afghanistan (species Afghanistan lies in Central Asia and is land-locked. marked with an octothorpe (#) are Afghan endemics) Its area is 652,000 sq km compared with Iran at 1. Acipenseridae (3) 1,648,195 sq km which has access to the sea in the Acipenser nudiventris Lovetzky, 1828 Persian Gulf and Sea of Oman, and the now Pseudoscaphirhynchus hermanni (Kessler, 1877) endorheic Caspian Sea. The Afghan ichthyofauna has Pseudoscaphirhynchus kaufmanni (Kessler, 1877) not been well-studied and is probably more diverse 2. Cyprinidae (50) than indicated here (Kottelat & Whitten 1996). Alburnoides holciki Coad and Bogutskaya, 2012 The ichthyofauna is relatively diverse for a Alburnoides taeniatus (Kessler, 1874) country isolated from the sea with large portions of Amblypharyngodon mola (Hamilton, 1822) its land mass being desert. The central spine of the Aspiolucius esocinus (Kessler, 1874) Hindu Kush Mountains forms a divide between the Bangana dero (Hamilton, 1822) southern and northern faunas with differing origins Barbodes sarana (Hamilton, 1822) as well as harbouring a fauna of its own.

  • The Status of the Endangered Freshwater Fishes in China and the Analysis of the Endangered Causes Institute of Hydrobiology
    The status of the endangered freshwater fishes in China and The analysis of the endangered causes HE Shunping, CIIEN Yiyu Institute of Hydrobiology, CAS, Wuhan, ITubei Province, 430072 Abstract More than 800 species of freshwater fishes are precious biological resources in inland water system of China. Among them, there are a great number of endemic and precious group, and a lot of monotypic genera and species. Recently, owing to the synthetic effects of the natural and human-beings, many of these fishes gradually became endangered. The preliminary statistic result indicates that 92 species are endangered fishes and account for 10% of the total freshwater fishes in China. For the purpose of protection of the biodiversity of fishes, it is necessary to analyse these causes which have led the fishes to become endangered. This report could be used as a scientific reference for researching and saving the endemic precious freshwater fishes in China. Key words Endangered freshwater fishes, Endangered causes, China In the process of the evolution of living things, along with the origin of life, the extinction of life also existed. In the long_ life history, the speciation and the extinction of living things often keep a relative balance. As time goes on, especially after by the impact of human beings activity of production and life, the pattern of the biodiversity were changed or damaged, more or less. At last, in the modern society, human beings activity not only accelerate the progress of society and the development of economy, but also, as a special species, become the source of disturbing_ to other species.

In Hungary, we recorded 5 known Myxobolus species (M. branchialis, M. caudatus, M. musculi, M. squamae, and M. tauricus) and described M. branchilateralis sp. n. In Portugal we recorded 6 Myxobolus species (M. branchialis, M. branchilateralis sp. n., M. cutanei, M. musculi, M. pfeifferi, and M. tauricus). Species found in the 2 habitats had similar spore morphology and only slight differences were observed in spore shape or measurements. All species showed a spe- cific tissue tropism and had a definite site selection. M. branchialis was recorded from the lamellae of the gills, large plasmodia of M. branchilateralis sp. n. developed at both sides of hemibranchia, M. squamae infected the scales, plasmodia of M. caudatus infected the scales and the fins, and M. tauricus were found in the fins and pin bones. In the muscle, 3 species, M. musculi, M. pfeifferi and M. tauricus were found; however they were found in distinct locations.

Since the work of J.J. Heckel (1846-1849), the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of freshwater fishes of Iran based on literature and taxon occurrence data obtained from natural history and new fish collections. This article lists 288 species in 107 genera, 28 families, 22 orders and 3 classes reported from different Iranian basins. However, presence of 23 reported species in Iranian waters needs confirmation by specimens.

Email: [email protected] General Mixed Yule- Coalescent (GMYC) and Poisson Tree Process (PTP) as well as haplotype network analyses. Using the BEAST program, we also examined temporal divergence patterns of Capoeta. The monophyly of the genus and the existence of three previously described main clades (Mesopotamian, Anatolian- Iranian, and Aralo- Caspian) were confirmed. However, the phylogeny proposed novel taxonomic findings within Capoeta. Results of GMYC, bPTP, and phylogenetic analyses were similar and suggested that species diversity in Iran is currently underestimated. At least four can- didate species, Capoeta sp4, Capoeta sp5, Capoeta sp6, and Capoeta sp7, are awaiting description. Capoeta capoeta comprises a species complex with distinct genetic line- ages. The divergence times of the three main Capoeta clades are estimated to have occurred around 15.6–12.4 Mya, consistent with a Mio- Pleistocene origin of the di- versity of Capoeta in Iran. The changes in Caspian Sea levels associated with climate fluctuations and geomorphological events such as the uplift of the Zagros and Alborz Mountains may account for the complex speciation patterns in Capoeta in Iran.

Accepted 17 February, 2012 Cytogenetic studies have helped in clarifying the problem of disagreement amongst taxonomists on the identity of a given species. Cytogenetic studies were performed on two fishes of the genus Schizothorax viz. Schizothorax curvifrons Heckel and Schizothorax niger Heckel (Cyprinidae: Schizothoracinae) obtained from Sindh Stream and Dal Lake Srinagar Kashmir, respectively. These fishes are considered to be the subspecies of the same species. The two species showed a diploid number of 98 in S. niger and 94 in S. curvifrons. The karyological data are analyzed in terms of the taxonomic aspects within this genus, and the validity of their existence as species chromosomally distinct from each other is emphasized.

INTRODUCTION Cytotaxonomy, the correlation between cytology and is, morphospecies with the possibility of demonstrating taxonomy, originated during the second half of the 19th reproductive isolation in controlled experiments (Koswig, century when it was discovered that some animal and 1973). Thus, the study of fish cytogenetics and genetics plant species may be classified according to their chro- is very promising in terms of solution to these problems.

Received in revised form 19 October 2015 However, taxonomy and phylogeny of these species remain unclear. In this study, we Accepted 14 November 2015 determined the complete mitochondrial genome of Schizopygopsis malacanthus. We also Available online xxx used the newly obtained sequence, together with 31 published schizothoracine mito- chondrial genomes that represent eight schizothoracine genera and six outgroup taxa to Keywords: reconstruct the phylogenetic relationships of the subfamily Schizothoracinae by different Mitochondrial genome Phylogeny partitioned maximum likelihood and partitioned Bayesian inference at nucleotide and fi Schizothoracinae amino acid levels. The schizothoracine shes sampled form a strongly supported mono- Schizopygopsis malacanthus phyletic group that is the sister taxon to Barbus barbus. A sister group relationship between the primitive schizothoracine group and the specialized schizothoracine group þ the highly specialized schizothoracine group was supported. Moreover, members of the specialized schizothoracine group and the genera Schizothorax, Schizopygopsis, and Gym- nocypris were found to be paraphyletic. © 2015 Published by Elsevier Ltd.
