Although they were once distributed throughout the coasts of Lake Biwa, the distributions of both species have narrowed up to the present day: they have become regarded as endangered species. For three years (2015–2017), we conducted field surveys at a ditch in Takashima, Shiga Prefecture and recorded the growth patterns of juveniles of both species. A series of surveys captured 700 and 40 juveniles, respectively, of C. magnostriata and C. minamorii oumiensis. The growth of juveniles of C. magnostriata was linear until early June, after which it reached a plateau. That saturation occurred at 20–25 mm body length. Few individuals exceeded 25 mm. Results suggest that the saturation was the result of sufficiently grown juveniles (20 mm or larger) running down to Lake Biwa. In 2015, the level at saturation for C. magnostriata was higher. The density of conspecific juveniles was thought to be lower than in other years. These results suggest that intra-specific resource competition affected this species. We were unable to trace the growth of C. minamorii oumiensis juveniles except in 2015 because ever fewer juveniles were captured in 2016 and 2017: our surveys captured fewer juveniles of this species decreased year by year. The study site is apparently the only spawning site for C. minamorii oumiensis at present. These facts support that C. minamorii oumiensis faces an immediate crisis. Overcoming this crisis requires elucidation of details of the C. minamorii oumiensis biology and hastening of the development of effective conservation tactics. Keywords: Cobitis striata species complex, conservation, fallow field biotope, life history, resource competition, spawning Introduction anecdotal reports have been published recently (e.g. Kawamura et al., 2015; Nakano et al., 2015). In recent years, many freshwater fishes in Japan have Both Cobitis magnostriata Nakajima, 2012 and C. become endangered. On the national red list in Japan (Japanese minamorii oumiensis Nakajima, 2012 are endemic species Ministry of Environment, 2014), 123 species are listed as distributed in the Lake Biwa riverine system. They are critically endangered (CR) or endangered (EN). An example is mutually similar in morphology (Saitoh, 1984), but C. the Cobitis striata species complex of 5 species and 11 magnostriata is larger than C. minamorii oumiensis in body subspecies occurring in Japan (Nakajima, 2017). All are listed length and egg size (Minamori, 1956). Saitoh and Matsuda as CR, EN or Vulnerable (VU) in the red list. Conservation of (1990) reported that adult individuals of C. magnostriata these species/subspecies is an urgent task. Details of the inhabit Lake Biwa during most of their life, except during the biology of this species complex, which is necessary for spawning season. During May–June, they migrate to and effective conservation, are little known, although some spawn at permanent water areas surrounding the lake, such as ＊Corresponding author: [email protected] - 49 - Morii et al ditches and side streams. Saitoh and Matsuda (1990) also reported that adults of C. minamorii oumiensis inhabit ditches connecting to Lake Biwa and the lake. They run to and spawn at temporary water areas such as paddy fields during June–July. A recent report (Nakano et al., 2015) has suggested that both species spawn sympatrically in a site, which is the only site where C. minamorii oumiensis is certain to have spawned in recent years. Some reports of the relevant literature (Saitoh, 1993; Saitoh and Matsuda, 1990) have suggested that C. magnostriata and C. minamorii oumiensis are distributed throughout the coasts of Lake Biwa. The distributions of both species have narrowed to their present state, however. Therefore, both species have been Fig. 1 Study site on June 12, 2016.

Parallel to genetic studies, morphological examinations are needed for further development of loach study, eventually ichthyology and fish biology. Digital archiving, concerning taxonomy, ecology, ethology etc., is one of the progressive challenges for the open science of biology. This paper aimed to online publish photo images, 3D models and CT scanned data of all the known clades of loaches inhabiting Japan (103 individuals in total with several type specimens), contributing to ichthyology and public interest of biodiversity/biology. © Kano Y et al.

Here, we report the sequencing of mitogenome, mtDNA the full mitochondrial genome (mitogenome) of R. osculus from a male fish collected from the Amargosa River Canyon in eastern California, USA. The assembled mitogenome is 16 658 base pair (bp) nucleotides, and encodes 13 protein-coding genes, and includes both a 12S and a 16S rRNA, 22 tRNAs, and a 985 bp D-loop control region.

DOUGLAS†‡ *Graduate Degree Program in Ecology and Department of Fish, Wildlife and Conservation Biology, Colorado State University, Fort Collins, CO 80523, USA, †Illinois Natural History Survey, Prairie Research Institute, University of Illinois, Urbana- Champaign, IL 61820, USA, ‡Department of Biological Sciences, University of Arkansas, Fayetteville, AR 72701, USA Abstract Global climate change is apparent within the Arctic and the south-western deserts of North America, with record drought in the latter reflected within 640 000 km2 of the Colorado River Basin. To discern the manner by which natural and anthropogenic drivers have compressed Basin-wide fish biodiversity, and to establish a baseline for future climate effects, the Stream Hierarchy Model (SHM) was employed to juxtapose fluvial topography against molecular diversities of 1092 Bluehead Sucker (Catostomus discobolus). MtDNA revealed three geomorphically defined evolutionarily significant units (ESUs): Bonneville Basin, upper Little Colorado River and the remaining Colora- do River Basin. Microsatellite analyses (16 loci) reinforced distinctiveness of the Bonneville Basin and upper Little Colorado River, but subdivided the Colorado River Basin into seven management units (MUs). One represents a cline of three admixed gene pools comprising the mainstem and its lower-gradient tributaries. Six others are not only distinct genetically but also demographically (i.e. migrants/generation <9.7%). Two of these (i.e. Grand Canyon and Canyon de Chelly) are defined by geomorphol- ogy, two others (i.e. Fremont-Muddy and San Raphael rivers) are isolated by sharp declivities as they drop precipitously from the west slope into the mainstem Colorado/ Green rivers, another represents an isolated impoundment (i.e.

Knowledge related to the age class structure, which is fundamentally important for such models, is expected to contribute to the effective conservation of endangered species. Two endemic spined loaches in the Lake Biwa river system, Cobitis magnostriata and C. minamorii oumiensis, have narrowed their distributions. Today, they are regarded as endangered species. For this study, to estimate their age structures, we surveyed body lengths of fish of the two species at a spawning site in Takashima, Shiga Prefecture for three years (2015–2017). A series of surveys captured 601 C. magnostriata individuals (488 male, 113 female) and 148 C. minamorii oumiensis individuals (60 male, 88 female). We applied models with different numbers of cohorts, k (1–7) for each sex and species and selected the best-fitted model among them. Models with k = 4 and k = 2 were selected respectively for C. magnostriata males and females. Models with k = 3 and k = 6 were selected respectively for C.

  • Comparable Ages for the Independent Origins of Electrogenesis in African and South American Weakly Electric Fishes
    Comparable Ages for the Independent Origins of Electrogenesis in African and South American Weakly Electric Fishes Se´bastien Lavoue´ 1,2*, Masaki Miya3, Matthew E. Arnegard4, John P. Sullivan5, Carl D. Hopkins6, Mutsumi Nishida2 1 Institute of Oceanography, National Taiwan University, Taipei, Taiwan, 2 Atmosphere and Ocean Research Institute, The University of Tokyo, Chiba, Japan, 3 Department of Zoology, Natural History Museum & Institute, Chiba, Japan, 4 Human Biology Division, Fred Hutchinson Cancer Research Center, Seattle, Washington, United States of America, 5 Cornell University Museum of Vertebrates, Ithaca, New York, United States of America, 6 Department of Neurobiology and Behavior, Cornell University, Ithaca, New York, United States of America Abstract One of the most remarkable examples of convergent evolution among vertebrates is illustrated by the independent origins of an active electric sense in South American and African weakly electric fishes, the Gymnotiformes and Mormyroidea, respectively. These groups independently evolved similar complex systems for object localization and communication via the generation and reception of weak electric fields. While good estimates of divergence times are critical to understanding the temporal context for the evolution and diversification of these two groups, their respective ages have been difficult to estimate due to the absence of an informative fossil record, use of strict molecular clock models in previous studies, and/or incomplete taxonomic sampling. Here, we examine the timing of the origins of the Gymnotiformes and the Mormyroidea using complete mitogenome sequences and a parametric Bayesian method for divergence time reconstruction. Under two different fossil-based calibration methods, we estimated similar ages for the independent origins of the Mormyroidea and Gymnotiformes.

  • Distribution Pattern of Cobitis (Telostei: Cobitidae) in Northern Kyushu Island, Japan
    Folia Zool. – 57(1–2): 10–15 (2008) Distribution pattern of Cobitis (Telostei: Cobitidae) in northern Kyushu Island, Japan Jun NAKAJIMA1, Norio ONIKURA1, Emi KITAGAWA2, Tadao KITAGAWA3 and Shin OIKAWA1 1 Faculty of Agriculture, Kyushu University, 2506 Tsuyazaki, Fukuoka 811-3304, Japan; e-mail: [email protected] 2 Osakana Research Institute, 3-2 Mitsugarasu, Nara 631-0061, Japan 3 Faculty of Agriculture, Kinki University, Nakamachi, Nara 631-8505, Japan Received 27 November 2006; Accepted 21 March 2008 Abstract. The distribution patterns of seven Cobitis species are analysed, namely, C. takatsuensis, C. biwae, the yamato complex, the Kyushu form of C. striata (small race), C. striata (middle race), the Hakata form of C. striata (middle race), and the Onga form of C. striata (middle race) in the northern Kyushu Island, Japan. C. takatsuensis is distributed in the upstream areas of some rivers in the northeastern part of the island. The yamato complex is widely distributed in the northern part of the island. The other five species are distributed in five areas separated by mountains. Although the yamato complex and the four striata complex species are often distributed in the same river system, the former inhabit upstream areas, while the latter inhabit the downstream reaches. The results of this study reveal that habitat fragmentation by mountains and the difference in longitudinal distribution lead to this complicated distribution pattern. Key words: Cobitinae, spined loach, geographical distribution Introduction The distribution patterns of freshwater fishes provide substantial geographical and biological information. Genuine freshwater fishes cannot migrate without connections of freshwater systems. Consequently, the heterogeneity in the geographic distribution pattern of genuine freshwater fishes results from changes in river systems and evolution of the fishes themselves (Watanabe 1998).

BMC Genomics (2021) 22:50 https://doi.org/10.1186/s12864-020-07360-w RESEARCH ARTICLE Open Access Comparative mitogenome analyses uncover mitogenome features and phylogenetic implications of the subfamily Cobitinae Peng Yu1,2, Li Zhou1,2, Wen-Tao Yang1,2, Li-jun Miao1,2, Zhi Li1, Xiao-Juan Zhang1, Yang Wang1,2* and Jian-Fang Gui1,2* Abstract Background: Loaches of Cobitinae, widely distributed in Eurasian continent, have high economic, ornamental and scientific value. However, the phylogeny of Cobitinae fishes within genera or family level remains complex and controversial. Up to now, about 60 Cobitinae mitogenomes had been deposited in GenBank, but their integrated characteristics were not elaborated. Results: In this study, we sequenced and analyzed the complete mitogenomes of a female Cobits macrostigma. Then we conducted a comparative mitogenome analysis and revealed the conserved and unique characteristics of 58 Cobitinae mitogenomes, including C. macrostigma. Cobitinae mitogenomes display highly conserved tRNA secondary structure, overlaps and non-coding intergenic spacers. In addition, distinct base compositions were observed among different genus and significantly negative linear correlation between AT% and AT-skew were found among Cobitinae, genus Cobitis and Pangio mitogenomes, respectively. A specific 3 bp insertion (GCA) in the atp8-atp6 overlap was identified as a unique feature of loaches, compared to other Cypriniformes fish. Additionally, all protein coding genes underwent a strong purifying selection. Phylogenetic analysis strongly supported the paraphyly of Cobitis and polyphyly of Misgurnus. The strict molecular clock predicted that Cobitinae might have split into northern and southern lineages in the late Eocene (42.11 Ma), furthermore, mtDNA introgression might occur (14.40 Ma) between ancestral species of Cobitis and ancestral species of Misgurnus.
