The map shows T. muticellus net travelled distance positions before (a) and during (b) river dry conditions in 2022 (triangles) and 2023 (circles). Red markers represent the intermittent groups (n = 21), while yellow markers represent the perennial groups (n = 64). Blue indicates riverbed areas with flow, while light red represents the dried area during the dry periods; the contouring is based on habitat mapping performed in March (a) and July (b) 2022. Note that one fish from the perennial group moved 200 m upstream during the drying process and is not shown on panel b.
