Recent advances in whole-genome sequencing have shed light on phylogenetic relationships, divergence times among major fish lineages, and the molecular basis of phenotypic diversity. This review encompasses the diversity of extant fishes and explores the variation in genomic organization and its evolutionary origins. This review begins with evaluating available genomic sequence resources with a focus on literally complete (‘telomere-to-telomere’) sequencing. Next, it discusses among-lineage variations in genomic contents, considering karyotype reports, genome sizes, and whole-genome duplication events. Additionally, we investigate three families of protein-coding genes, visual opsins, aquaporins (Aqps), and Hox genes, as they offer insights into morphological and physiological differences among major fish lineages. Overall, our technical basis of analyzing fish genomes and the knowledge of genomic organization provide valuable insights into our vertebrate-wide understanding of how molecular mechanisms specifying variable phenotypes are encoded in genomic sequence information.</p>","PeriodicalId":13237,"journal":{"name":"Ichthyological Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138547716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the anguloarticular feature of <i>Lissonanchus</i> is likely unique within the Gobiesocidae and is regarded as a putative autapomorphy for the genus.

Although <i>Lissonanchus</i> was previously included in the subfamily Diademichthyinae, the genus does not share any diagnostic features of that subfamily, and the subfamilial assignment of the genus remains equivocal, like other Indo-Pacific genera considered as <i>incertae sedis</i> within the Gobiesocidae (e.g., <i>Aspasmogaster</i> Waite 1907, <i>Conidens</i> Briggs 1955, and <i>Creocele</i> Briggs 1955).</p>","PeriodicalId":13237,"journal":{"name":"Ichthyological Research","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138530346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we examined the abiotic environmental variables and population densities of fishes, including three salmonids, in 30 reaches of the Setose River, Hokkaido, Japan, across altitudes (120–450 m) and maximum water temperature (15–26 °C) gradients to determine the distribution of major fish species in this system. The densities of white-spotted charr Salvelinus leucomaenis , southern Asian Dolly Varden Salvelinus curilus , masu salmon Oncorhynchus masou , fluvial sculpin Cottus nozawae , and stone loach Barbatula oreas varied along environmental gradients despite their wide distribution sympatrically. We further investigated the interspecific interactions between three potentially competitive salmonids, white-spotted charr, Dolly Varden, and masu salmon. We observed that in the three-species system, including upstream Dolly Varden, salmon occupied upstream areas colder than those inhabited by charr, which is contrary to the pattern reported for charr and salmon two-species systems, wherein charr are found in the colder upstream areas. In underwater observations, salmon preferred faster water velocities than charr and Dolly Varden. Dolly Varden were found exclusively on the riverbed, followed by charr, whereas salmon occurred further away from the riverbed. Analysis of the stomach contents revealed that all three salmonids depended on terrestrial insects, but only Dolly Varden consumed benthic aquatic insects. In our three-species system that included Dolly Varden (preadapted to benthos foraging), no difference was observed in the degree of terrestrial insect consumption between charr and salmon. These results are in striking contrast to the reports of charr preying on relatively more aquatic insects than those consumed by salmon in charr and salmon two-species systems. Therefore, we speculate that Dolly Varden and salmon influence interspecific interactions between charr and salmon and between charr and Dolly Varden, respectively, explaining the distinct longitudinal distribution and feeding habits observed in two- vs. three-species systems. These variant interspecific interactions among the three competing species may have driven the expansion of their sympatric zones.","PeriodicalId":13237,"journal":{"name":"Ichthyological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
