“…The ocelot was the most affected by land uses associated with the lack of forest and by the distance to the native forest, showing a rapid drop in the probability of occurrence as the productive land uses and the distance to the native forest increased, especially in areas with 10%–50% of lack of cover. These results support the hypothesis that the ocelot is more sensitive to human disturbance compared to the smaller felids (de Oliveira et al., ; Dematteo et al., ; Di Bitetti, Paviolo & De Angelo, ; Di Bitetti, Paviolo, De Angelo et al., ; Di Bitetti et al., ; Kasper et al., ; Rinaldi et al., ).…”

“…However, the southern tiger cat had a greater tolerance to increasing distances from the continuous forest than the other felids, supporting our prediction that the southern tiger cat has a greater tolerance to fragmentation than the ocelot. Also, the observed differences from the margay's and jaguarundi's responses might be due to the fact that, being the smaller of the cats, the southern tiger cat could satisfy its habitat requirements in smaller fragments than the other felids as a result of its smaller home‐range size (Kasper et al., ).…”

“…For this purpose, we overlaid a grid with cell size equivalent to the home range of a female for each species using ArcGIS 10.1. These home ranges were obtained from radiotelemetry studies carried out in the Atlantic Forest region: 17.4 km 2 for the ocelot (Crawshaw, ), 19.6 km 2 for the jaguarundi (Crawshaw, ), 21.8 km 2 for the margay (Kasper et al., ), and 16.4 km 2 for the southern tiger cat (Kasper et al., ). We randomly selected a single presence record from each cell that contained more than one record (Kanagaraj, Wiegand, Kramer‐Schadt, Anwar & Goyal, ; Sattler et al., ).…”

“…Four Neotropical small and medium felids—the ocelot ( Leopardus pardalis ), the jaguarundi ( Herpailurus yagouaroundi ), the margay ( Leopardus wiedii ), and the southern tiger cat ( Leopardus guttulus )—constitute a guild of carnivores with overlapping geographic distributions in the endangered Atlantic Forest ecoregion (de Oliveira et al., ; Macdonald & Loveridge, ; Trigo et al., ). Local‐scale studies of habitat use show that these four felids avoid areas with high human impact, but the three smaller ones use human‐modified areas more frequently than do ocelots (Di Bitetti, De Angelo, Di Blanco & Paviolo, ; Kasper, Schneider & Oliveira, ; Rinaldi, Rodriguez, Carvalho & Passos, ). The last pattern could result from interference competition exerted by the ocelot on the smaller felids (the “pardalis” effect; de Oliveira et al., ; Cruz et al., ), whereby ocelots may occur in better conserved areas while the small felids are restricted totally or partially to suboptimal habitats (de Oliveira & Pereira, ; de Oliveira et al., ; Di Bitetti et al., ).…”

Four Neotropical small and medium felids—the ocelot, jaguarundi, margay, and southern tiger cat—have overlapping geographic distributions in the endangered Atlantic Forest. Local studies show that these felids avoid areas with high human impact, but the three smaller ones use human‐modified areas more frequently than do ocelots. To understand how landscape changes affect the habitat distribution of these four felids in the Atlantic Forest of Argentina, we used maximum entropy models to analyze the effect of environmental and anthropogenic factors. We estimated niche breadth and overlap among these felids. The conversion of the native forest to land uses without trees was the most important variable that determined the habitat distribution of the four species. For all four species, the optimal habitat covered about 1/3 of the study area and corresponds mainly to the native forest areas. Nearly 50% of these areas had some level of protection. The niche width was higher for the small felids than for ocelots. Niche overlap was high for all species pairs, but higher among the small felids and lower for each of these with the ocelot. The four felids were negatively affected by native forest loss, with ocelots being more sensitive than the smaller felids. The conversion of unprotected forest areas to other types of land uses would imply a greater habitat loss for these felids. The protection of current remnants of Atlantic Forest in Argentina is important for the long‐term conservation of the four felids. Abstract in Spanish is available with online material.

“…This is consistent with observations in other regions: the abundance of L. wiedii was higher in regions with absence or low density of ocelots, likely as a result of low interspecific competition (Carvajal-Villarreal et al 2012;Kasper et al 2016;Vanderhoff et al 2011). Other medium-sized felids also showed a similar density pattern in sites with low density of ocelots, such as L. geoffroyi in central Argentina and Bolivia (Geoffroy´s cat;Caruso et al 2012;Cuellar et al 2006), and L. tigrinus in the Brazilian Atlantic forest (Oncilla; OliveiraSantos et al 2012).…”

The margay, Leopardus wiedii, and the ocelot, L. pardalis, are sympatric species through their distribution areas. Some studies indicate that L. pardalis exerts a strong influence on other smaller felids. Our goal in this study was to estimate the density and activity patterns of these felid species in two vegetation types at Sierra Norte of Oaxaca, southwestern Mexico. We expected that L. pardalis had a high density relative to other felids due to its ecological plasticity, as well as segregation in the activity pattern between species. We placed camera traps in 22 sites in the semi-evergreen forest and 22 sites in the cloud forest, from July 2014 to June 2015. We estimated density using the Cormack-Jolly-Seber probabilistic model with the program MARK and assessed the degree of activity overlapping between species by the coefficient of overlapping Δ 1 in the program R. We recorded low abundance of L. pardalis (8.3 individuals) and a higher abundance of L. wiedii (51.5 individuals). The density of both species was 7.8 individuals /100 km 2 and 81 individuals/100 km 2 , respectively. Both species displayed predominantly nocturnal activity. The overlap coefficient between species in the semi-evergreen forest was high (Δ 1 = 0.75, CI = 0.63-0.90). Factors such as differences in vegetation type and the presence of a large number of transient individuals may influence the density of Leopardus. The lower density of L. pardalis and the high conservation status of the cloud forest may contribute to the higher density of L. wiedii in Sierra Norte of Oaxaca. Our results suggested that both species showed a highly overlapping activity pattern, and the activity pattern of the margay is seemingly unaffected by the presence of the ocelot. We provided information about density and activity of medium-sized felids, as well as on the factors that may potentially affect these patterns in mountain tropical forests.El margay Leopardus wiedii y el ocelote L. pardalis son simpátricos a través de sus distribuciones. Algunos estudios indican que L. pardalis ejerce una influencia fuerte en otros felinos más pequeños. Nuestro objetivo fue estimar la densidad y el patrón de actividad de estos felinos en dos tipos de vegetación en la Sierra Norte de Oaxaca, en el Sureste de México. Esperábamos que L. pardalis presentara una densidad alta en comparación con otros félidos, debido a su plasticidad ecológica y también, esperábamos una segregación en el patrón de actividad entre especies. Ubicamos 22 sitios con trampas cámara en la selva mediana y 22 sitios en el bosque mesófilo de julio 2014 a junio 2015. Estimamos la densidad usando el modelo probabilístico de Cormack-Jolly-Seber con el programa MARK y evaluamos el grado de sobreposición de la actividad entre especies por medio del coeficiente de sobreposición Δ 1 en el programa R. Registramos una abundancia poblacional baja de L. pardalis (8.3 individuos) y una mayor de L. wiedii (51.5 individuos). La densidad poblacional de ambas especies fue 7.8 individuos/100 km 2 y 81 individuos/100 km 2...
