Data from: The effect of dam construction on the movement of dwarf caimans, Paleosuchus trigonatus and Paleosuchus palpebrosus, in Brazilian Amazonia

Run-of-the-river hydroelectric dams cause changes in seasonal inundation
of the floodplains, and this may cause displacement of semi-aquatic
vertebrates present before dam construction. This study evaluated the
movement of crocodilians before and after the filling of the Santo Antônio
hydroelectric reservoir on the Madeira River in the Brazilian Amazon,
which occurred in November 2011. We radio-tracked four adult male
Paleosuchus palpebrosus and four adult male Paleosuchus trigonatus before
and after the formation of the reservoir between 2011 and 2013. The home
ranges of the P. palpebrosus varied from < 1 km2 to 91 km2 and the
home ranges of the P. trigonatus varied from < 1km2 to 5 km2. The
species responded differently to time since filling and water level in
weekly movement and home range. However, overall the dam appears to have
had little effect on the use of space by the individuals that were present
before dam construction.
