We studied a Myocastor coypus (Molina, 1782) population during the authorised hunting season (AHS) and outside the hunting season (OHS) in the floodplain of the Paraná River (Argentina), a representative area for this species within its original geographic range. The aims of this work were to describe and compare fluctuations in population parameters (relative abundance, sex ratio, age structure) and in the physical condition between these two periods. Additionally, we discussed the possible occurrence of simultaneous influence of environmental factors (particularly the hydroperiod) and hunting pressure on these parameters. The absolute density during the AHS was 2.78 individuals/ha. No differences in the trapping success index were found between AHS and... |
