Rodents from southern Patagonian semi-arid steppes (Santa Cruz Province, Argentina)

The little-known mammalian fauna of southern Santa Cruz Province is studied by means of live-trapping and examination of owl pellets at 11 localities. Thirty-nine individuals of seven species were recorded in a total of 753 trap nights during the years of 2004 and 2005. Additionally, we identified 3...

The mammal sampling effected by live-traps and owls was rarely coincident, with some species collected only by traps or by owls.
