Figure 1. Distribution map of sample sites and effort. Relief
map of the Maroni Basin (delimited in black) showing 83 sampling points
(red dots) of specimens collected. Names of main tributaries are

& Jarvis, 2008) project website
(http://www.worldwildlife.org/pages/hydrosheds) and the R packages
raster v2.9.5 (Hijmans, 2019), rgdal v1.4-8 (Bivand, Keitt, &
Rowlingson, 2019), shapefiles v0.7 (Stabler, 2013), and mapplots v1.5-1
(Gerritsen, 2018).
