In this study, we conducted ﬁeld surveys at two sites to elucidate the biologi cal traits of the hypoxia-tolerant bivalve Veremolpa micra . We detected new settlements at both sites during summer. More highly reduced conditions in the surface sediment were recorded at Site-A than at Site-B in August 2013. Following this hypoxic event, shell growth of V. micra at Site-A decelerated, whereas that at Site-B increased. The population density after recovery from the hypoxic event decreased more at Site-B than at Site-A. Body size exhibited very little growth at both sites during the fall and winter, but there was rapid growth during the subsequent spring and summer, with sexual maturity being reached in early summer. Our ﬁndings demonstrated that the growth rates and survival pat terns of the hypoxia-tolerant bivalve populations diﬀered between sites with diﬀerent degrees of sediment reduction. To understand the biological traits of hypoxia-tolerant bivalve species, it is necessary to consider and evaluate spatial dif-ferences in hypoxic stress at the local site level.","PeriodicalId":56054,"journal":{"name":"Plankton & Benthos Research","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41689865","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}

Surveys conducted using larva nets and a beam trawl in July showed that the horizontal egg and larva distributions of I. elongata and S. zunasi both overlapped considerably in the inner estuaries; however, I. elongata settled in the estuaries while S. zunasi retained a pelagic distribution. A comparison of the vertical distributions of the two species in the estuary showed that I. elongata larvae were dispersed from the surface to near-bottom layers during the ﬂood tide, and moved downwards to avoid being swept out of the estuary after the high tide, while S. zunasi larvae remained spread throughout the water column in all tidal phases. The ﬁndings suggest the existence of niche segregation during the pe lagic larval period in the two species. Thus, by examining diﬀerences in larval mouth sizes, which are much larger in I. elongata than in S. zunasi, it appears that prey preference varies between the two species, prey specialization occurs, and there is no niche competition between the two species.","PeriodicalId":56054,"journal":{"name":"Plankton & Benthos Research","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46770482","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}

Armouring has the potential to affect coastal environments and induce changes in the abundance and diversity of marine communities, and its effects might by increased by wide adoption. Moreover, compared with temperate locations, the effects of armouring have been less studied in tropical and subtropical areas. Okinawa Island, the largest and most populated island of the Ryukyu Archipelago in southern Japan, has been affected by numerous civil and military engineering works. After decades of development, less than 40% of its coastline remains natural, and yet impacts from armouring on local marine communities have been overlooked until recent years. The aim of this research was to evaluate effects of near-shore armouring on the surrounding environment by comparing diversity and abundance of coral rubble mobile cryptofauna benthic communities between armoured and control sites. Across six different geographic locations, coral rubble was sampled in front of subtidal breakwaters and at nearby control sites. Armoured sites were associated with lower cryptofauna abundances and reduced richness and diversity at higher taxonomic levels (phylum and class). Reduction in spatial complexity could be a plausible reason for the observed patterns. Impacts could be mitigated by combining technical innovations, habitat restoration, and use of natural spaces as buffers for coastal protection. Since less than half of Okinawa Island’s coastline remains in a natural state, environmental conservation should be prioritized.","PeriodicalId":56054,"journal":{"name":"Plankton & Benthos Research","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44588180","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}

Methods to increase the abundance include transplanting juvenile Atrina spp. in the sea and main-taining the survival rate high. We conducted transplant experiments to compare the survival rates of one genetic lineage of Atrina between 1) transplant sites and 2) preventive measures against predation. We conducted ﬁve runs of transplant of Atrina artiﬁcial seeds (about 10 cm in shell length) in the inner and outer sea areas, using cages with diﬀerent mesh opening sizes. We found that 1) Atrina sp. survived better at stations in the outer sea area than in the inner sea area. This trend in the last run was partly explained by a heavy deposition of mud at a station in the inner sea area. 2) Atrina sp. survived better in cages with mesh opening size < 20 mm than those with the size > 20 mm. This was attributed to predatory animals, which presumably include the whelk Rapana venosa , octopi Octopodidae spp., and swimming crabs Charybdis spp. recorded by underwater time-lapse camera. In conclusion, transplant to the outer sea area and protec tion from predators with a mesh < 20 mm opening are promising to increase the survival rate of one genetic lineage of Atrina transplanted in the Ariake Sea.","PeriodicalId":56054,"journal":{"name":"Plankton & Benthos Research","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46828648","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}
