In this study, the population structure and tidal zonation of sympatric B. multiformis and B. attramentaria were examined at stations on the Ashizaki tidal ﬂat from 2010 to 2015. A cohort of smaller in dividuals （ shell length ［ SL ］ : 10.0–17.1 mm ） of B. multiformis was formed in 2010; however, few cohorts formed during the following years, leading to a decrease in the population density. Batillaria multiformis recruited in the summer and fall, with SL growth of 5–6 and 10–17 mm in June–July and September, respectively, of the second year, and of 20 mm in May– July of the third year. By contrast, B. attramentaria recruited every year （ SL growth: 5–6 and 10–17 mm in May and sum -mer, respectively, of the second year, and 15–20 mm in the third summer ） and maintained a high population density throughout the study period. The two species recruited in low- to mid-intertidal zones in most cases. Subsequently, a propor tion of B. attramentaria moved to the high-intertidal zone, while B. multiformis remained in the low-intertidal zone. Our data suggest that the populations of the two batillariid species studied herein exhibited slower growth rates and attained larger adult sizes compared with other populations in Japan. Less frequent recruitment of B. multiformis in our study site implies that this population of B. multiformis may be vulnerable.","PeriodicalId":325376,"journal":{"name":"Japanese Journal of Benthology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115331281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a previous study, we observed the loss of larger individuals of the hermit crab Diogenes nitidimanus during the mid-reproductive season. There-fore, we experimentally investigated predation intensity of the portunid crabs Charybdis japonica and Portunus pelagicus on D. nitidimanus collected from the tidal ﬂat of the Waka River to elucidate the eﬀects of predator body size, prey shell type and shell size, and season. Each predator was given six prey items with a combination of two shell types （ Umbonium and Batillaria ） and three shell size classes. We replaced eaten prey items daily with identical ones in terms of shell size and type, and recorded the number of prey items eaten over 10 days per predator. However, we were unable to analyze the eﬀect of season for P. pelagicus because of the species ʼ limited periods of collection. C. japonica preferred prey with small, Umbonium -type shells. The total number of prey items eaten increased in summer, but not with body size. By contrast, P. pelagicus preferred prey with Batillaria -type shells, and predator body size tended to be a more important factor in the context of me -dium- and small-sized shells. Batillaria- type shells are likely more resistant to crushing pressure than Umbonium -type shells. More smaller prey were eaten during the experiment, which does not explain the loss of larger individuals at the study site.","PeriodicalId":325376,"journal":{"name":"Japanese Journal of Benthology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134143241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
