So these pumas are pretty small, which is understandable given that where cougars and jaguars co-exist, the cougars tend to be small.

I have a question. Unlike in South America, why is it that in Central or North America, such as in Belize or Mexico, jaguars are so small that they weigh around 50 kg (110 lbs), enough for even female pumas (https://www.cambridge.org/core/journals/journal-of-zoology/article/food-habits-of-jaguars-and-pumas-in-jalisco-mexico/035C96247BD24E086381BC75E1DC9FF5) and female South American jaguars (https://web.archive.org/web/20100620231016/http://www.science.smith.edu/departments/Biology/VHAYSSEN/msi/pdf/i0076-3519-340-01-0001.pdf) to weigh about the same or rival them?

He said that he estimates that the largest Jaguar in Pinero weights at least 120 kilograms. Hato Pinero is a big Ranch located in Estado Cojedes, Venezuela

Very interesting, Epaiva. Maybe the situation in that part of Venezuela is suited for cooperation? It definitely has advantages, as it will enable the males to get rid of competition in the reproduction department. I wonder if they also hunt together and share food?

Was there any interest from the newspapers? Anything know about Dr. W. Jedrzejewski? Has he published?

According to what he said he is planning to publish a complete book of Jaguars and Pumas in Venezuela, he said exacly what you said it will enable males to get rid of competition in the reproduction department, he did not mention if they hunt together and share food, Hato Pinero has a good number of Jaguars about 30, they are protected in the Ranch, it is the best place in Venezuela to spot them in the wild but sadly I went there 3 times without luck.
He published two papers but I don`t know how to post them in the Forum
