| a rad-based linkage map and comparative genomics in the gudgeons (genus gnathopogon, cyprinidae). | the construction of linkage maps is a first step in exploring the genetic basis for adaptive phenotypic divergence in closely related species by quantitative trait locus (qtl) analysis. linkage maps are also useful for comparative genomics in non-model organisms. advances in genomics technologies make it more feasible than ever to study the genetics of adaptation in natural populations. restriction-site associated dna (rad) sequencing in next-generation sequencers facilitates the development of ... | 2013 | 23324215 |
| genomic architecture of habitat-related divergence and signature of directional selection in the body shapes of gnathopogon fishes. | evolution of ecomorphologically relevant traits such as body shapes is important to colonize and persist in a novel environment. habitat-related adaptive divergence of these traits is therefore common among animals. we studied the genomic architecture of habitat-related divergence in the body shape of gnathopogon fishes, a novel example of lake-stream ecomorphological divergence, and tested for the action of directional selection on body shape differentiation. compared to stream-dwelling gnathop ... | 2015 | 26179373 |
| sperm morphology and imp distribution in membranes of spermatozoa of cyprinid fishes ii. | the morphology and intramembranous particle (imp) distribution of spermatozoa were investigated in four species of cyprinid fishes, gnathopogon elongatus elongatus, pseudogobio esocinus, acheilognathus lanceolatus and puntius tetrazona. in particular, observation of imp distribution was conducted as an aspect of comparative spermatology in cyprinid fishes and was continued from a previous paper (ohta et al., 1994 (8)). although the fundamental structures of the spermatozoa were similar among the ... | 1995 | 8521530 |
| development of free neuromasts with special reference to sensory polarity in larvae of the willow shiner, gnathopogon elongatus caerulescens (teleostei, cyprinidae). | to find how larval fish sense mechanical stimuli via their free neuromasts, we examined morphological changes in free neuromasts in the larval willow shiner, gnathopogon elongatus caerulescens. free neuromasts were found on the body surface of newly hatched larvae and their number increased on both the head and trunk with larval growth. the apical surface of free neuromasts changed in outline from a circle to a lozenge shape as the number of sensory cells increased in the prelarval stage, and th ... | 1995 | 18397121 |
| the relationship between the length of the cupulae of free neuromasts and feeding ability in larvae of the willow shiner gnathopogon elongatus caerulescens (teleostei, cyprinidae) | free mechanosensory neuromasts of larval fishes have been described as playing a complementary role to vision in feeding behaviour (disler, 1971; iwai, 1972a,b). in certain species or under limited conditions, free neuromasts play a major role in detecting prey. the larvae of mottled sculpin cottus bairdi can feed on artemia in the dark by using free neuromasts (jones and janssen, 1992). artificially blinded surface-feeding aplocheilus lineatus can detect insects on the water surface by means of ... | 1994 | 9318022 |
