a Composite satellite map, modified from GoogleEarth imagery, that illustrates the changing shoreline of the lake in 2005, 2012, 2013 and 2016. The featured area is the bay indicated by the black arrow labelled ‘A’ in Fig. 1. The green circle ‘M12’ denotes the sampling location where numerus Biomphalaria have been found during all malacological inspections from November 2017 to December 2019. The changing shoreline is most likely resultant from lowering lake levels, see b, as well as, upon influx of sediments from the seasonal river in the bottom part of this image. b. Annual changes in the lake surface levels during 1992–2019 period (see https://ipad.fas.usda.gov/cropexplorer/global_reservoir/gr_regional_chart.aspx?regionid = eafrica&reservoir_name = Malawi), as detected by remote altimetry, denoting two particularly low-level periods, in 1996–1998 and 2017–2019, which may help explain the changing shoreline shown in a as the lake recedes in depth. m MSL: meters above Mean Sea Level
