“…Based on other wide studies (>2.5 years), young ocelots disperse and establish a home range after the 14-35 months of age (Laak, 1991;Haines et al, 2005;Mares, Moreno, Kays, & Wikelski, 2008). Due to the duration of this study (27 month), there is some uncertainty as to the classification of these two individuals as residents, however it also provides insight into this parameter in the ocelot population in the area.…”

“…The ocelot is mainly nocturnal, but in some areas exhibits day time activities (Ludlow & Sunquist, 1987;Caso, 1994). The birth rate is 1:1, the subadults occupy the natal area until sexual maturity is reached, and take several months to occupy the permanent area as adults (Laak, 1991;Caso, 1994;Haines, Tewes, Laack, Grant, & Young, 2005). Diet varies throughout its distribution: prey <100g are more frequent, however medium-sized prey provide greater biomass (de Oliveira et al, 2010).…”

Abstract:The ocelot Leopardus pardalis is of particular significance in terrestrial communities due to its ecological role within the group of small-sized felids and as a mesopredator. However, despite the reduction of ocelot habitat in Southeast Mexico, there are still very few ecological studies. This research aimed to contribute with some ecological aspects of the species in this region. For this, 29 camera trap stations were established in a rain forest in Los Chimalapas (an area of 22km 2 ) during a two years period (March 2011-June, 2013, in Oaxaca state, Southeast Mexico. Data allowed the estimation of the population density, activity pattern, sex ratio, residence time, and spatial distribution. Population density was calculated using Capture-Recapture Models for demographically open populations; besides, circular techniques were used to determine if nocturnal and diurnal activity varied significantly over the seasons, and Multiple Discriminant Analysis was used to determine which of the selected environmental variables best explained ocelot abundance in the region. A total of 103 ocelot records were obtained, with a total sampling effort of 8 529 trap-days. Density of 22-38individuals/100km 2 was estimated. Ocelot population had a high proportion of transient individuals in the zone (55%), and the sex ratio was statistically equal to 1:1. Ocelot activity was more frequent at night (1:00-6:00h), but it also exhibited diurnal activity throughout the study period. Ocelot spatial distribution was positively affected by the proximity to the village as well as by the amount of prey. The ocelot population here appears to be stable, with a density similar to other regions in Central and South America, which could be attributed to the diversity of prey species and a low degree of disturbance in Los Chimalapas.

Epub 2014 December 01.Key words: camera-trapping, capture-recapture, Los Chimalapas, CJS Model.Ocelot Leopardus pardalis (Linnaeus, 1758) distribution ranges from the Southern United States to Northern Argentina (Murray & Gardner, 1997;Sunquist & Sunquist, 2002). It is found in a wide variety of habitats where it coexists with other cats such as the jaguar Panthera onca (Linnaeus, 1758), the puma Puma concolor (Linnaeus, 1771), the margay Leopardus wiedii (Schinz, 1821), and the jaguarundi Puma yagouaroundi (Lacépède, 1809) (Murray & Gardner, 1997;Sunquist & Sunquist, 2002;de Oliveira et al., 2010). Within these habitats, the ocelot can impact other species due to its role as a mesopredator or through intraguild predation (Sunquist & Sunquist, 2002;de Oliveira et al., 2010). In areas where other large-size predators are absent, such as the jaguar and the puma, this species may become the primary predator.Some studies indicate that ocelots prefer areas with closed canopy and avoid large open areas (López-González, Brown, & GalloReynoso, 2003;Harveson, Tewes, Anderson, & Laak, 2004;Martínez-Calderas et al., 2011). The ocelot is mainly nocturnal, but in some areas exhibits d...

“…Since the remaining Przewalski's gazelles occur in several small subpopulations with few breeding individuals (Jiang, 2004;Li et al, 2012), inbreeding is likely inevitable and may lead to a loss of genetic diversity and thus inbreeding depression with the associated potential adverse effects . Given that individuals within the same subpopulation are closely related , the modeled effects of inbreeding on this gazelle may have been underestimated in Vortex, as the program quantifies the reduction in first-year survival due to inbreeding depression (Brito and Da Fonseca, 2006;Haines et al, 2005;Miller and Lacy, 2005).…”

Although separated from the mainland, it is likely that the ocelots on BCI are able to cross the ~200 m gap, even if only rarely (at least 1 of 14 radio-collared ocelots swam off BCI to the mainland, Moreno et al, unpubl.).…”

Abstract:Home range shifts prior to natal dispersal have been rarely documented, yet the events that lead a subadult to abandon a portion of its home range and venture into unfamiliar territories, before eventually setting off to look for a site to reproduce, are probably related to the causes of dispersal itself. Here, we used a combination of manual radio-tracking and an Automated Radio Telemetry System to continuously study the movements of a subadult male ocelot (Leopardus pardalis), a solitary carnivore with sex-biased dispersal, on Barro Colorado Island, Panama, for 18 months from May 2003 through October 2004. The subadult ocelot's parents were also radio-tracked to record possible parent-offspring interactions within their home ranges. At the age of ca. 21 months the subadult gradually began to shift its natal home range, establishing a new one used until the end of the study, in an area that had previously been used by another dispersing subadult male. Only three parent-offspring interactions were recorded during the four months around the time the range-shift occurred. The apparent peaceful nature of these encounters, along with the slow transition out of a portion of his natal home range, suggest the subadult was not evicted from his natal area by his parents. The timing of the shift, along with the subadult's increase in weight into the weight range of adult ocelots four months after establishing the new territory, suggests that predispersal home range shifts could act as a low risk and opportunistic strategy for reaching adult size, while minimizing competition with parents and siblings, in preparation for an eventual dispersal into a new breeding territory.
