There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Today I attended a SYMPOSIUM named  LOS FELINOS DE VENEZUELA with the best researchers of Cats in the country with a great surprise, Dr Wlodzimierz Jedrzejewski who has been doing a research of Jaguars and Pumas for more than 9 years found out a Coalition of two big adult males in Hato Pinero in  the Venezuelan Llanos they have already killed 3 males and have a huge territory with 3 females for them, they are mating  without any fight between them, Jaguars are supossed to be solitary cats. 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

Surprising indeed! Aren't Venezuelan llanos similar to el Pantanal? Guessing that behavior is less common in the Amazon basin or places where big prey are more sparse?

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/...75E1DC9FF5) and female South American jaguars (https://web.archive.org/web/201006202310...1-0001.pdf) to weigh about the same or rival them?

@BorneanTiger
They are very small compared to the ones you find in el Pantanal in Brazil and in Los Llanos Venezuela where you find the largest Jaguars because they dont have the same variety and huge numbers of Prey animals they find in those places, in Venezuela you find huge Jaguars in Los Llanos and smaller ones not as small as the ones you find in Central America or Mexico in the rest of the country with the smaller ones in the Venezuelan Amazon.

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

With jaguars now in the USA, "North American jaguar" would make more sense than "Central American jaguar". Sometimes, even Mexico is not considered part of Central America:
