“…Given the availability of extensive comparative work within Catostomidae (Nelson, 1948), we document morphological diversity in only one of the currently recognized subfamilies, Catostominae (Harris and Mayden, 2001). Within Catostominae, anatomy is presented for three recognized tribes: Moxostomatini (Moxostoma macrolepidotum, USNM 267283; Fig.…”

Cypriniformes (which includes the minnows, carps, loaches, algae-eaters, stone loaches, and suckers) is a morphologically diverse and incredibly speciose order of teleosts. It has been suggested that a number of evolutionary innovations, key to improved hearing and feeding, have played an important role in cypriniform fishes' success. One such innovation, the Weberian apparatus, is a novel assemblage of vertebral elements and modified ribs that relay and amplify sound pressure changes from the gas bladder to the inner ear. The Weberian apparatus unites Cypriniformes with other major orders into an extremely species-rich group of fishes, the Otophysi. Together, otophysan fishes comprise one of the largest groups of fishes in the world, as well as the majority of freshwater fishes. Here we present a detailed comparison of the Weberian apparatus in a number of cypriniform families using cleared and stained specimens. We present data regarding inter- and intrafamilial morphological variation within Cypriniformes. With few, but evolutionarily important, exceptions we find that diagnostic features of the Weberian apparatus characterize each family. Interspecific variation within each of the families Balitoridae, Gyrinocheilidae, and Catostomidae is only slight, whereas variation among subfamilies within Cyprinidae and Cobitidae is far more significant. This comparative study identifies a number of distinct morphologies, some of which appear highly correlated with ecological niche. For example, inhabiting swift-moving waters appears to be a key factor in the encapsulation of the anterior gas bladder in some cobitids, balitorids, and gobionin cyprinids.

“…The Chinese sucker Myxocyprinus asiaticus, which is designated a class II stateprotected animal and vulnerable species by the International Union for Conservation of Nature (IUCN) (Wang, 1998), is the only representative of the Catostomidae in Asia (Nelson, 1976;Harris and Mayden, 2001). Historically, M. asiaticus was mainly distributed in the Yangtze and Minjiang rivers, but currently, the only extant wild population is that of the Yangtze River, where it is mainly confined to the upper reaches (Wang, 1998).…”

ABSTRACT. Studies of genetic diversity and genetic population structure are critical for the conservation and management of endangered species. The Chinese sucker Myxocyprinus asiaticus is a vulnerable monotypic species in China, which is at a risk of decline owing to fluctuations in effective population size and other demographic and environmental factors. We screened 11 microsatellite loci in 214 individuals to assess genetic differentiation in both wild and cultured populations. The single extant wild population had a higher number of alleles (13) than the cultured populations (average 7.3). High levels of genetic diversity, expressed as observed and expected heterozygosity (H O = 0.771, H E = 0.748, respectively), were found in both wild and cultured populations. We also report significant differentiation among wild and cultured populations (global F ST = 0.023, P < 0.001). Both STRUCTURE analysis and neighbor-joining tree revealed three moderately divergent primary genetic clusters: the wild Yangtze population and the Sichuan population were each identified as an individual cluster, with the remaining populations clustered together. Twenty-two samples collected from the Yangtze River were assigned to the cultured population, demonstrating the efficacy of artificial propagation to avoid drastic reduction in the population size of M. asiaticus. These genetic data support the endangered status of the M. asiaticus and have implications for conservation management planning.

Therefore, the 16S rRNA gene has great potential for the inference of divergences among the cyprinid lineages and resolution of relationships within Cyprininae.…”
