Akihiko Koyama, Ryutei Inui, Norio Onikura, Yoshihisa Akamatsu, Tomoko Minagawa, Habitat Characterization Based on Crab Fauna in the Temperate Estuarine Intertidal Zone of the Seto Inland Sea, Japan, Estuaries and Coasts, 10.1007/s12237-020-00725-0, 21, 641-652, 2020.03, Although crabs are effective indicator species for evaluating the health of estuarine environments, the relationship between crab communities and environmental conditions in temperate river estuaries is poorly investigated. This study aimed to clarify the physicochemical factors that affect crab fauna in temperate areas, as well as classify and characterize habitat based on the similarity of crab fauna. Data of crab fauna and physicochemical environmental factors were collected at 199 sites in two temperate rivers. These survey sites were spatially arranged to cover the estuarine zone (i.e., tidal freshwater to polyhaline water) and the intertidal zone (i.e., the high tide to low tide line). The result of a direct gradient analysis showed that salinity and median particle size, in particular, affected crab fauna. Moreover, the survey sites were classified into seven groups based on the similarity of crab fauna, which were modeled with moderate accuracy using three variables: salinity, elevation, and percentage of silt. From these variables, we were able to identify seven different habitat types: salt marshes covered with fine or coarse sediment, upstream zones with gravelly sediment, intermediate zones between salt marshes and tidal flats, sand tidal flats with scattered hard structures, monotonous sand flats, and mud flats. Our findings suggest that maintaining the salinity gradient and diversity of sediment grain size is necessary to conserve crab species diversity in temperate river estuaries. Effective ecosystem conservation in these areas needs to take into account the physicochemical conditions in the seven identified habitat types.. |

This study aimed to identify the physicochemical factors that influence goby fauna and richness, which have high species diversity in temperate riverine estuaries, by conducting field surveys. We collected gobies and measured six physicochemical factors (median particle size; percentage of gravel, sand, and mud; salinity; and elevation) in the intertidal zone of two riverine estuaries flowing into the Seto Inland Sea of Japan. Twenty-six species of gobies were found at 191 sites during our surveys. To classify the survey sites by goby fauna, we stratified 132 sites, where more than two species of goby were found, into seven groups by using two-way indicator species analysis. The results of canonical correspondence analysis and classification and regression tree suggested that the goby fauna changed along these physicochemical environmental gradients. In particular, sediment characteristics might be an important factor that influences the goby fauna. However, no relationship was found between species richness of gobies, as revealed by the result of generalized linear mixed model. Therefore, our data indicate that species diversity of gobies utilising various environments cannot be maintained by conservation of a specific environment in riverine estuaries. The diversity and heterogeneity of the physicochemical environments, especially sediment conditions, need to be maintained and controlled for the conservation of the gamma diversity of estuarine goby.. |

In this study, analyses of mitochondrial (cytochrome b) and nuclear (glyt, myh6, and RAG1) genes were conducted to investigate patterns and magnitudes of intraspecific differentiation among A. rivularis populations in Japan and adjacent continental areas. Phylogenetic analysis of the mitochondrial gene sequences resolved four major lineages—the Japan lineage (JL), a northern continental lineage (NCL), and two southern continental lineages (SCL1 and SCL2)—with uncorrected pairwise sequence distances of 9.4–15.2% (estimated divergence times, 7.9–17.1 Myr). Two lineages (JL and SCL1) occurred in both the Honshu and Kyushu districts of Japan. Compared with populations in continental areas, most Japanese populations exhibited less genetic diversity. The JL was divided into two well-differentiated sub-lineages distributed on Honshu and Kyushu islands, respectively. Kyushu Island, as well as areas on Honshu where the species is known to have been introduced, also harbored the SCL1 lineage, which constituted most of the populations on Kyushu. The applied nuclear DNA data strongly suggest that hybridization between the Japan and continental lineages has occurred on Kyushu Island. The artificial introduction hypothesis, instead of a two-origin scenario, best explains the origin of the SCL1 in Japan.. |

indication of fluvial and amphidromous life histories within a single lineage, Ichthyological Research, 10.1007/s10228-018-0637-4, 65, 4, 462-470, 2018.11, We evaluated the morphological, distributional, and genetic characteristics of the freshwater sculpin, Cottus pollux, in Kyushu Island, Japan. Based on pectoral fin ray number, the sculpins inhabiting 30 rivers were divided into two types [modes 13 (M13) and 15 (M15)]. We evaluated four environmental parameters: length of main river (L-MR), average gradient of main river (G-MR), distance from sampling site to river mouth (D-SM), and gradient around sampling site (G-S), and compared the two types. L-MR, D-SM, and G-S were significantly larger for the rivers that contained M13 fish than for those containing M15 fish. M13 individuals were distributed in the upstream areas of large river systems, suggesting a fluvial life history, whereas M15 individuals were distributed in the downstream areas of small river systems, indicating an amphidromous life history. We conducted phylogenetic analysis based on mitochondrial 12S rRNA [788 base pair (bp)] and control regions (386 bp). Mitochondrial DNA analysis showed that both M13 and M15 groups were genetically of C. pollux middle-egg type (ME). Our findings proposed the hypothesis that C. pollux ME in Kyushu Island exhibits dimorphism in both morphological and distributional traits. Additionally, haplotype distribution indicated that the fluvial M13 populations had higher genetic specificity in each river in contrast to the existence of one genetic group of amphidromous M15 individuals in Kyushu Island.. |

Shigeru Kitanishi, Norio Onikura, Takahiko Mukai, A simple SNP genotyping method reveals extreme invasions of non-native haplotypes in pale chub Opsariichthys platypus, a common cyprinid fish in Japan, PLoS One, 10.1371/journal.pone.0191731, 13, 1, 2018.01, Biological invasion by non-native subspecies or populations is one of the most serious threats to ecosystems, because these species might be easily established in the introduced area and can negatively affect native populations through competition and hybridization. Pale chub Opsariichthys platypus, one of the most common fish in East Asia, exhibits clear genetic differentiation among regional populations; however, introgression and subsequent loss of genetic integrity have been occurring throughout Japan due to the artificial introduction of non-native conspecifics. In this study, we developed a simple SNP genotyping method to discriminate between native and non-native mitochondrial DNA (mtDNA) haplotypes in pale chub using real-time PCR assay. We then investigated the distribution patterns of non-native pale chub in Tokai region, located in the center of Honshu Island, Japan and developed a predictive model of the occurrence of non-natives to reveal the factors influencing their invasion. The specificity and accuracy of the genotyping method were confirmed by using samples whose haplotypes were determined previously. Extensive occurrence of non-native haplotypes in Tokai region was detected by this method. In addition, our models suggested that the presence of non-natives varied greatly depending on the river system, and was positively influenced by the impounded water areas. Our method could accurately distinguish between native and non-native haplotypes of pale chub in Japan and suggested key environmental factors associated with the presence of non-natives. This approach can greatly reduce experimental costs be a great contribution for quantitative investigation.. |

Digging uncovered 19 spawning nests. The number of eggs and the standard length of the guarding male were positively correlated. Nine spawning nests were examined using in situ resin casting. All casts had structures characteristic of callianassid shrimp burrows and were most likely those of Nihonotrypaea japonica. Spawning nests had significantly greater average diameters than shrimp burrow openings and may have been widened by G. macrognathos.. |

Onikura N, Nakajima J, Miyake T, Kawamura K, Fukuda S, Predicting the distribution of seven bitterling species inhabiting northern Kyushu Island, Japan, Ichthyol Res, 59, 124-133, 2012.04, The distributions of seven bitterling species and subspecies—Tanakia lanceolata, T. limbata, Acheilognathus tabira nakamurae, A. rhombeus, Rhodeus ocellatus kurumeus, R. ocellatus ocellatus, and R. atremius atremius— in northern Kyushu were predicted using generalized linear models (GLMs) in order to provide information helpful for conserving native bitterlings and preventing the expansion of alien bitterling species. Predictions were made according to the following procedure: (1) a set of GLMs for each species was formulated using environmental data from 710 sites that were derived using digital maps and GIS software, from which the best fit model for each species was selected using the Akaike information criterion for predicting the fish occurrence, (2) model performance was evaluated based on the receiver-operating characteristics (ROC) analysis using occurrence and environmental data from 362 sites, and (3) potential distributions of the bitterling were analyzed using the best fit models and environmental data for 1,272 sites, of which 200 data points without occurrence data were prepared. The best fit models revealed that 4–6 environmental factors were important in predicting seven bitterling distributions, which was supported by the area under the ROC curve (AUC) values of these fishes ranging from 0.753 to 0.927. The AUC values in model evaluation were significantly greater than 0.5 for six fishes, suggesting the moderate accuracies of these best fit models for predicting the fish distributions. These predictive models can be used for evaluating potential native bitterling richness and the potential distribution expansion of an alien subspecies.. |

The toxic effects of 17 pesticides were investigated using acute and reproduction tests of crustaceans (Ceriodaphnia dubia and Daphnia magna), early life stage toxicity test of zebrafish, Danio rerio, and growth inhibition test of green algae (Selenastrum capricornutum). Principal component and cluster analyses were then applied to the toxicity data obtained to classify these pesticides. Seven pesticides exhibited high acute toxicity to crustaceans (LC50s were below 10ppb). EC50s for C. dubia and D. magna reproduction tests were lower than LC50 values of most pesticides used in this study. A few of them exhibited fairly high toxicity to either D. rerio or S. capricornutum (EC50s were below 10ppb). The principal component analysis of these toxicity data revealed that three components mainly contributed to the toxic effects of the pesticides: components highly toxic to crustaceans, fish, and green algae, respectively. Cluster analysis was then carried out based on the data of the principal component analysis. Results indicate that these 17 pesticides were classified into 5 categories. This study demonstrated the importance of using various organisms to understand the toxic effects of chemicals on the ecosystem.. |
