And this is the information I have for jaguars that surpass the 90 kg threshold in Mexico, those measurements are different nowadays that jaguars have had such a fragmented habitat with fee prey and hunting pressure.

Been honest, none of those weights are from Mesoamerica, in the strict sence of the word. In fact, while some maps shows to you that Mesoamerica starts in the middle of Mexico and others even up to the Eastern Sierra Madre, other shows only the region of the Mayas, which is the Mexican states of Chiapas and Yucatan, and the countries of Guatemala, Belize, and the northern part of Honduras and El Salvador; the last one is the region normally used in our contries. Even if we take the "larger" region (the map that I put here), the Sinaloa state is still out of that area (the second map, region is red):

So, the information that you posted is very good, and I will save it (thanks for that), but certainly those from "Mexico" are probably closer to the population of the northern region of Mexico and Texas/Arizona than to the Mesoamerica one, the image even say that they are from Sinaloa.

The record from Nicaragua (also not Mesoamerica) is very insteresting, as with 81.2 kg, it is the heaviest jaguar recorded in Central America (from Guatemala to Panama), and as heavy as the biggest pumas in Canada/Chile.

About Leopold, this is the original source, and been honest he doesn't state that the measurements are from Mexico per se, and they look more like those from South America if you compare it with other regions:

About this phrase in the pdf: "In Central America and southern Mexico, both sexes trend slightly larger than they do to the north or south". Certainly they did not read the documents, if not they will see that is the contrary, northern and southern jaguars are relative bigger than those from southern Mexico and Central America. Reply
