“…Long-term monitoring data of biodiversity and ecosystems collected prior to such events, if they exist, allow evaluation of the impact through before/after comparisons (Whanpetch et al 2010). A long-term ecosystem monitoring program, entitled Monitoring Sites 1000, covers three coastal sites on the Sanriku (northeastern Tohoku) coast that were heavily affected by the tsunami.…”

The primary goal of the 60th anniversary symposium of the Ecological Society of Japan (ESJ) was to re‐examine the role of the Society. The first of five lectures, “Development of Long‐term Ecological Research in Japan,” discussed the increasingly important role of long‐term and networked research studies. Ecological research in Asia faces many challenges, because Asia features natural and anthropogenic landscapes with highly diverse ecosystems. “Developing Strategies of the Ecological Society of Japan for Worldwide Societies of Ecology with Special Reference to Strategies for Asia” emphasized the role of ESJ in promoting ecological research and outreach in Asia. Ecosystem sustainability is a key issue in both the theory and practice of ecosystem management. A framework concept of an environmental and biodiversity cycle was proposed in the session “Linking Community and Ecosystem Dynamics” for understanding the mechanisms driving the sustainability of ecosystems. Ecosystem services are essential aspects of land use and conservation planning and management. “Integrating Models of Ecosystem Services and Land Use Changes” reviewed recently‐developed models that simulate patterns of land‐use change and analyze its effects on ecosystem services and also recommended future directions for collaboration among researchers. “Disaster Resilience and Coastal Ecology” highlighted the contributions of ecologists to evaluating the resilience of damaged coastal ecosystems and provided sound proposals to local communities and governments for rehabilitation plans. The past achievements and future directions of ESJ were discussed by the panelists and the audience in “Past and Future of the Ecological Society of Japan.”

“…Tsunami are a recurring natural hazard that have repeatedly disturbed coastal ecosystems, such as sandy beaches, seagrass beds, coral reefs, mangrove forests and near shore terrestrial ecosystems (Cochard et al 2008;Whanpetch et al 2010;McAdoo et al 2011). Considerable changes in community structure and decreases in abundance and species richness were observed after the huge tsunami associated with the 2004 Indian Ocean earthquake, the 2007 Peru earthquake and the 2010 Chile earthquake (Whanpetch et al 2010;Lomovasky et al 2011;Jaramillo et al 2012).…”

“…Considerable changes in community structure and decreases in abundance and species richness were observed after the huge tsunami associated with the 2004 Indian Ocean earthquake, the 2007 Peru earthquake and the 2010 Chile earthquake (Whanpetch et al 2010;Lomovasky et al 2011;Jaramillo et al 2012). It has been suggested that tsunami have long-lasting effects on coastal ecosystems and that the restoration process is long-standing (Whanpetch et al 2010;Jaramillo et al 2012). It is essential to precisely estimate the impact of a tsunami on the local community to understand the ecosystem response.…”

Immediate impact of the tsunami associated with the 2011 Great East Japan Earthquake on the Plecoglossus altivelis altivelis population from the Sanriku coast of northern Japan

The huge tsunami associated with the 2011 Great East Japan Earthquake severely impacted the ecosystems on the Sanriku coast of Japan. The life history traits of ayu, Plecoglossus altivelis altivelis, which have a one-year amphidromous life history, were investigated by otolith analyses in two rivers of the Sanriku coast just after the tsunami compared with results before the tsunami to reveal the immediate impact of the tsunami. Hatching date compositions differed between the upstream migrants before and after the tsunami. The migrants after the tsunami were solely composed of fish hatched during October and November, whereas the migrants before the tsunami were mostly composed of fish hatched in September. Discrepancies between the hatching dates of the migrants and drifting larvae (hatched larvae) indicate that selective mortality of early-hatched fish occurred during the tsunami. Differences in otolith Sr:Ca ratios between upstream migrants before and after the tsunami suggest that fish surviving the tsunami inhabited saline water and earlyhatched fish that inhabited the estuary decreased selectively in number because of the severe erosion around the river mouth. The oceanic growth period shortened in accordance with the change in hatching date. These results show that the tsunami drastically altered the ecology of P. altivelis altivelis on the Sanriku coast.

“…The impacts of these earthquakes are vast in the context of spatial scale; tsunamis and land-level changes affect hundreds of kilometers of coastline (Lay & Kanamori, 2011;Tajima et al, 2013) and have great potential to affect coastal communities. This is because tsunami waves can transport benthos from their suitable habitats (Castilla, 1988;Castilla et al, 2010;Whanpetch et al, 2010;Lomovasky et al, 2011;Takami et al, 2013), heavily damage seagrass beds (Whanpetch et al, 2010) and coral reefs (Chavanich et al, 2005;Campbell et al, 2007), and remove and redeposit coastal sediments on a large spatial scale (Lomovasky et al, 2011). Subsidence, too, may have a substantial impact because it can transport substrate with attached organisms to deeper places.…”

“…Most previous studies that have estimated the impacts of earthquakes on coastal populations have been conducted at relatively small spatial scales, that is, at only a single site or only a few sites (Whanpetch et al, 2010;Lomovasky et al, 2011). Because the influence of local coastal topography on the wave impact of a tsunami can be strengthened by stochastic effects (Wijetunge, 2006;Mori et al, 2011), in cases when only one or a few sites are selected for sampling, the stochastic effects can become too large to obtain a general picture of regional-scale impacts of the tsunami.…”
