Figure captions
Figure 1 Four river catchments surveyed in Southeast Asia (Malaysia and Singapore). Catchment boundaries are highlighted in blue. Inset depicts Singapore and its surrounding areas.
Figure 2 Changes in land-use cover over time across the four catchments surveyed: Danum (top-left); Endau (top-right); Nee Soon (bottom-left); and NSFPF (bottom-right). Red pixels represent catchment area associated with forest loss while green pixels represent catchment area associated with forest gain. Black circles represent the exact sites where fish specimens were collected. All sites were sampled in both the before and after time points.
Figure 3 Probability distribution of pair-wise intra-specific differences in TP between the before and after time points.
Figure 4 Distribution (average and standard deviation) of mean slope coefficients describing the relationship between mean intra-specific change in TP over time (Δ \(\overset{\overline{}}{\text{TP}}\)) and various ‘null’ variables (filled circles) as well as forest loss metrics (empty circles). Mean slope coefficients were parameterised over 100 iterations of generalised linear models using a Bayesian approach (see Methods).
