I was treating the jaguars from Central America, and southern North America as one group under the 'Mesoamerican' category.

Don't worry my friend, that is why we are here, to learn more every day.

Based in these figures, I think that we can separate three main groups, that are not subspecies of course:

1 - Northern group: USA and northern Mexico.
2 - Central group: Southern Mexico and Central America (Guatemala to Panama).
3 - Southern group: All South America, with many single populations.

This is just an easy separation for comparison porpuses, but South America had several diferent populations, like that of the Llanos in Venezuela, those from Peru and Bolivia, the giants of el Pantanal in Brazil, the one of the Amazonas and the almoust unknown at the north of Argentina, among many others.

It is incredible that jaguars do not have subspecies and only several populations with clinal diferences.

I'm particularly interested in seeing a study on the weighs and measurements of Llanos Colombian jaguars and Atlantic forest jaguars, particularly of the Argentinian side. We have no data on Colombian jaguars from Llanos besides recent trackings by camera trapping footage, while the Atlantic forests jaguars have limited data on sizes though better than the Colombian ones. I feel like we would be quite surprised if we were to see how big the Colombianos Llanos jaguars can get as the males there look just impressive as Pantanal ones. 

One of the few records I know of Colombian jaguars is this old newspaper article which I posted on a different forum regarding a cattle eating jaguar that weighted 12 arrobas or 136+kg and measured almost 3 meters

I'm not sure about which kind of measurement styles they used for the jaguar since we are not dealing with scientists here, but nonetheless that is a huge cat.

I'm in the process of discussing this with Edu.
The people at Aurora were with him to view Pantanal jaguars and they actually named a Jaguar after them, Aurora female.
He said that he recalls them saying they were a bit smaller than the Pantanal ones but he said he'd speak with them about it again and get back to me.
I'll relay what he says once he does.

Here is what Edu said about Jaguars from La Aurora

"I asked to our vet about the jaguar at La Aurora and he told me they are smaller than in the Pantanal although the landscape is very similar"

"I'm still waiting for the exactly weights of the jaguars there" Reply
