Freshwater bioerosion site, Kaladan River, Myanmar. a Map of Myanmar with location of the downstream area of Kaladan River (red frame). b Map of the study site. The violet asterisk indicates the freshwater rock-borer’s site, and white circles indicate the levels of river water above sea level. The yellow circles indicate main towns. The maps were created using ESRI ArcGIS 10 software (www.esri.com/arcgis); the topographic base of the maps was created with Natural Earth Free Vector and Raster Map Data (www.naturalearthdata.com), Vector Map (VMap) Level 0 (http://earth-info.nga.mil/publications/vmap0.html), and ASTER GDEM (https://lpdaac.usgs.gov/node/1079) (Maps: Mikhail Yu. Gofarov). c River site with freshwater rock-borer’s ecosystem. The red arrow indicates siltstone rocks, a substrate of rock-boring bivalves. d Fragment of the black siltstone outcrop, the submerged part of which forms the basis of freshwater rock-borer ecosystem.
