“…Alternatively, the maximum activity in summer at PPET, could also reflect the different reproductive tactics in males and females of solitary carnivores (Sandell, 1989). Whereas the increased activity of females may be the effect of greater energetic requirements to feed their weaned young (the birth season for Geoffroy's cat occurs from December to May; Ximénez, 1975;Johnson and Franklin, 1991), as has been observed for European lynxes, Lynx lynx (Okamura et al, 2000;Schmidt et al, 2009), males may be induced to increase their level of activity to devote more time in activities related to the marking and maintenance of territory in response to the presence of dispersing juveniles (Geffen and Macdonald, 1993).…”

a b s t r a c tTo understand the activity and movement patterns of Leopardus geoffroyi, we compared its behavior by radio-tracking 10 individuals in two areas of the Pampas grassland of Argentina: Campos del Tuyú Wildlife Reserve (CdT; 2F, 2 M, n = 1753 activity fixes), and Ernesto Tornquist Provincial Park (ETPP; 4F, 2 M, n = 1700 fixes), an area more strongly affected by human activities. The proportion of active fixes varied between areas and ranged from 38.4 ± 4.4% at CdT to 42.9 ± 8.1% at ETPP. In both areas, L. geoffroyi was mainly nocturnal, with maximum activity at 1:00 h (70.9%) at CdT and 4:00 h (75.6%) at ETPP. Activity patterns were highly correlated between areas and, within each area, between sexes, possibly in relation to the nocturnal activity of its major prey. Seasonal variations were detected, with the least diurnal and nocturnal activity in spring. In both study areas, Geoffroy's cats presented variations in the amount of nocturnal activity corresponding to differences in nocturnal luminosity. However, these variations were different: cats were most active when the night was brighter at CdT, whereas at ETPP activity was lower in brighter nights. At CdT, the linear distance of movement between locations averaged 685.8 ± 496.8 m and males moved 1.4 times farther than females. This distance was shorter at CdT than ETPP (1087.9 ± 932.8 m), where males had movements 4.5 times greater than females. The mean speed of travel did not differ between areas (CdT: 0.44 ± 0.45 km/h; ETPP: 0.44 ± 0.78 km/h), but males tended to move faster than females. In the grasslands of Argentina, human disturbance did not affect the patterns of activity of L. geoffroyi but cats appeared to be forced to spend more time active and move over greater distances in the more disturbed area.

“…This little-known South American carnivore is distributed from Bolivia and southern Brazil throughout southern Argentina and Chile (Redford and Eisenberg, 1992). It mainly occupies dwells in arid and semiarid environments such as the Monte desert and the Patagonian steppe, but it can also be found in a wide range of habitat types including grasslands, open forests, and wetlands (Ximénez, 1975;Perovic and Pereira, 2006;Bisceglia et al, 2008). This species is nocturnal and solitary (Diaz and Barquez, 2002).…”

“…Este carnívoro es principalmente nocturno y habita tanto en ambientes secos como semiáridos. Es un predador oportunista y su dieta actual consiste en lagomorfos, pequeños roedores y aves (Ximénez 1975;Manfredi et al 2004Manfredi et al , 2011Perovic y Pereira 2006). El peso promedio del macho adulto es de alrededor de 4,9 kg, en tanto que las hembras pesan cerca de 4,2 kg (Cabrera y Yepes 1960;Johnson y Franklin 1991;Oliveira 1994;Lucherini et al 2006).…”

RESUMENEl objetivo de este trabajo es caracterizar y comparar los patrones de modificaciones óseas producidos por dos carnívoros autóctonos de Sudamérica, el zorro pampeano y el gato montés, sobre partes esqueletarias de pequeños vertebrados. Para esto se realizó una experiencia en un parque zoológico local, ofreciendo 10 conejos en forma controlada, a cada uno de los predadores mencionados. En esta oportunidad se presentan los resultados de los restos no ingeridos, para los cuales se analizó la representación anatómica y los patrones de fractura. Los resultados indican que tanto el gato montés como el zorro pampeano generan una destrucción ósea significativa en los restos de conejo, lo cual impacta directamente en la representación de los individuos. Los elementos con mayor supervivencia fueron los huesos largos, la pelvis, el cráneo y la mandíbula. Por otra parte, la densidad ósea resultó ser uno de los factores que condicionó la destrucción diferencial de los elementos. Si bien nuestros resultados no permiten diferenciar las modificaciones generadas por estas dos especies de carnívoros, los patrones observados aportan nuevos datos que ayudan a distinguir estos conjuntos de aquellos originados por otros predadores como por ejemplo, aves rapaces diurnas y nocturnas.
