Temporal changes of the fish community in seagrass beds in Funakoshi and Otsuchi bays after habitat destruction caused by a tsunami in 2011

The temporal changes in the fish community structure before and after a tsunami in 2011 were investigated in Funakoshi and Otsuchi bays, Iwate prefecture, on the Pacific coast of northern Japan. Fish species richness, abundance, biomass, and species composition were analyzed in relation to temporal variability of biotic and abiotic environmental conditions in two sub-intertidal seagrass Zostera marina beds. Mean seagrass shoot density decreased to
