Comparing Cats: A Discussion of Similarities & Differences

[Dark Jaguar]

@Shadow

Exept the info from my post isn't only based on ''what I think'' or neither ''IF'' speculation as they also include results of long term researches made in 2 different biomes of Brazil stated by the people who work in the field themselves for many years in both Iguaçú and Refúgio Ecológico Caiman and not to mention the other areas (as stated by Joares May on the Puma case ) as these people travel the whole country seeking for captures and researches, so nothing better than they themselves confirm the fact that Pumas will seek smaller preys and will avoid direct encounter with Jaguars. The mutual respect could probably happen in Caatinga.

Indeed there's very little information on violent direct interspecific confrontation of these animals and the reason why we can already have an accurate idea just by the fact Pumas won't show up in areas jaguars are seen the most exept during certain times of the day because there are a larger, bulky, big headed cat roaming around in the same enviornment.

Pumas are powerful cats but most of places they coexist with jaguars, they are smaller than the jaguar.

In addition to that I am gonna drop a part of the PHD study by Leandro Silveira  ( COMPARATIVE ECOLOGY AND CONSERVATION OF JAGUAR (PANTHERA ONCA) AND PUMA (PUMA CONCOLOR), IN THE CERRADO AND PANTANAL ) about the difference in habitat of the 2 species in PNE ( Parque Nacional das Emas ) area of Cerrado.

Here's the PNE map the red triangles are the Cerrado Jaguars tracks monitored and the black dots are the Cerrado Pumas tracks monitored between January 2001 and December 2002.

''The differences in habitat use between jaguars and pumas in the Emas National Park region (PNE) analyzed through radio-telemetry, reflect the distribution of individuals monitored (Figure 21 and 24). Cerrado Jaguars were rarely observed outside the boundaries of the PNE, while almost all individuals of Cerrado Pumas monitored at some point left the reserve, with only one exception (Figure 24). Thus, anthropized habitats were part of the landscape used by Pumas, much more than for jaguars.

The results from the use of habitats by Cerrado Jaguars in the PNE region, between January 2001 and December 2002, indicated that the niche of the species comprises basically two segments of areas: the eastern region of the Park formed by the valley that encompasses the springs on the right bank of the Jacuba River, leaving the Park, to the proximities of the mouth with the Rio Formoso and the headwaters of the Cabeceira Alta and Rio Formoso streams (Figures 24 and 25). The Pumas did not restrict their distribution and habitat use in the same way (Figure 24).

Despite the apparent uniformity of the habitat of Campo Sujo in the eastern region of the PNE, where the Cerrado jaguars were concentrated, it was observed that the individuals monitored used the flat areas of slate more in the nocturnal than in the diurnal period (Figure 26).''

I am pretty sure if the Cerrado Jaguars weren't occuping the PNE area on large scale within that period of time there would be way more Cerrado Pumas venturing into the PNE area. Reply
