This data comes from the study: Jaguar movement database: a GPS‐based movement dataset of an apex predator in the Neotropics, almost every single renowned jaguar biologist like Hoogesteijn, Tortato, Crashaw et al. Collaborated in the formulation of this public database which I have attached here. It contains the weights for jaguars fro multiple locations that we can discuss here:

For the data on the jaguars from the Chaco I contacted the biologist Jeffrey Thompson, whose done most of the captures of jaguars in Paraguay, and utilized the data with his name on it to create a table for Chaco specimens. Please keep in mind that some of the weights may belong to jaguars from the Paraguayan Pantanal or Atlantic Forest as the captured locations were not inputted in the file, but as far as I know he's only done captures in the Chaco so I'm quite confident these are all from that biome. Here it is:

EDITED

This jaguar that I posted recently was captured by him and I'm assuming is ID:10, as he confirmed to me he weighed 110 kg:

Just as I stated before, jaguars from the Chaco grow similar in size to those from the Cerrado, both populations producing jaguars capable of reaching or surpassing 110 kg in weight. I'm hopeful we will get more data from them in the future, we're lacking plenty from Bolivia.

I finally have the official data for jaguars from the Chaco in Paraguay, the biologist Rocky McBride sent me his study PROJECT JAGUAR Final REPORT 2002 – 2011 FARO MORO ECO RESEARCH, in which the weights of multiple jaguars from the Chaco, Pantanal, and Atlantic Forest of Paraguay are included. Here are the tables:

The area Fortin Patria is located in the Pantanal, Mbaracaju, and Morombi in the Atlantic Forest, the rest is Chaco:

The jaguars from the Paraguayan Pantanal here will be added to the Pantanal table.

Further information on the areas studied, it appears as though the state of jaguars in here is very similar to that of jaguars in Brazil last century, where many are killed for consuming cattle in retaliatory attacks, plus severe habitat loss:

The next post will be the compilation table for this population, which will include the data from this study, the jaguar Qaramta from Argentina, and the male jaguar captured recently by Jeffrey Thompson that I mentioned before. He's not in this study as this study ran until 2011 and that particular jaguar was captured between 2016 and 2017. Reply
