Mesoamerican Jaguars

From Research study jaguar, other wildlife in Mexico (Source)
“Jaguars actually used to live in the southwest United States as well,” Nielsen explained recently. But humans ran them out, killing many of them in the process. The jaguars in Sonora represent the northernmost breeding population in their distributional range, which extends to southern South America. While slightly smaller than the more elongated puma, jaguars are fast, low to the ground and powerful predators. In this area, a male might average 130 pounds or so, and it hunts by itself, stalking and ambushing prey."  *This image is copyright of its original author  *This image is copyright of its original author
Here are more pictures regarding Central American jaguars. I've also posted pictures of cougars on the exact place so it's easy to compare.

Anyone knows why Central American jaguars in are smaller than South American jaguars?

Suki sporadically appeared in grainy photos over the next few years on the Northern Jaguar Reserve and Viviendo con Felinos ranches, once with a javelina she had killed. Another time near the site of a dead mountain lion. One of the ranchers called her “matapumas” (“she who kills pumas”), which made her a bit of a local legend for a while. / Part 2 of 6  *This image is copyright of its original author

They lack the prey density, their population has declined drastically and habitat is different. Even within S. America they can show significant size differences, like the Amazon compared to the Pantanal and Los Llanos. Even the Pantanal Jaguars will show differences between the N. and S. Populations
Jaguars are in Costa Rica.

What are the difference between north Pantanal and south Pantanal? And Pantanal jaguars size diffences between those northern and southern Pantanal?

S. Pantanal is harder to spot Jaguars, they usually are baited to get them to come out and get the "Safari Shot" Likes this In the South they have a harsher wet season with more flooding and more of the land has been destroyed for Soy farming but the North is sadly catching up to the South in that regard. Also tourism in the South is much less developed compared to the North so their accommodations are usually farms In the south you'll see Giant Anteaters, Macaws and Anacondas more often. In the North, it's teaming with Capyvara and Caiman, it's also more protected from farming so the land is much less molested *for now* Jaguars here are guaranteed, especially in the meeting of the 3 rivers where you'll see the largest Jaguars alive, here is most likely the most dense concentration of Jaguars on Earth. Because the Caiman population made such a drastic comeback after they were almost hunted to extinction not so long ago, the Jaguar have also made a huge comeback as well, it's also why here you'll see Jaguars hunting Caiman far more than any where else. A side note, the South was hit with devastating fires this year as well, while the North avoided them luckily but who knows how long that'll last. My Friend/Guide who's worked the North/South and Amazon all his life really thinks the Pantanal will be lucky if 10% of it is left by the time the current regime is done with it unless we completely boycott Brazilian beef and soy. Here is a good write up on the differences as well "The Pantanal is divided into the northern Pantanal, covering 1/3 of the whole area, and the southern Pantanal, covering 2/3 of the area with the environment of wetlands is at its most intense. There are excellent accommodations where you can stay while visiting both areas and enjoy nature. To get to the Pantanal in Brazil you need to fly to Cuiaba if you would like to visit the North of the Pantanal or fly to Campo Grande if you would like to visit the South Pantanal. Tours to the Pantanal can combine very well with trips to Iguazu Falls and Bonito. Northern Pantanal At a slightly higher elevation, the Northern Pantanal is slightly drier than the south, and possibly more accessible via the main city of Cuiabá. Southwest of town is the city of Poconé and the beginning of the Transpantaneira Highway , the only road that crosses the region , which goes south and is about 145 km (90 miles ) long to Porto Joffre . The Transpantaneira Highway is composed of about 100 wooden bridges, earning a place in the Guinness Book of Records as the highway with the highest number of bridges in the world. On each side of the road you will see large artificial trenches filled with water throughout the year. These pools provide a haven for wildlife during the dry season and therefore great opportunities for wildlife viewing throughout the year. If you happen to travel through the Transpantaneira Highway between the months of October and January, you can be rewarded with a glimpse of the elusive jaguar. Southern Pantanal When the complex series of river systems overflow at the beginning of the rainy season, large open plains of the southern Pantanal of Mato Grosso do Sul are swallowed by vast quantities of water . Flooding causes an explosion of aquatic vegetation which in turn swells the population of fish that abound with abundant food and cover. During these months , it is easy to understand why the first Portuguese explorers mistook the region with an ocean at first glance, naming the Xaraés Sea. If traveling in the wettest months a generous supply of mosquito repellent is advisable. From April onwards, heavy rains give way to clearer skies and drier , warmer weather , making it an excellent time for photographers to visit the region . As temperatures rise in the water levels begin to decrease, in July, the pools of water have shrunk to mere ponds - called " ebb Castle " - surrounded by large expanses of grassland lush . The 260 species of fish that reveled in the deluge of the previous season are now left scrambling for space and flocks of birds take advantage of this banquet. The concentration of different species this time of year is an absolute delight for birdwatchers and anyone with a passion for nature. Between August-September dry season reaches its peak and the arid landscape takes on a similar appearance to the African savannah, before the clouds and rain return again in October. https://www.brazilnaturetours.com/brazil-tours/pantanal
A 2019 survey by the Center of Biological Diversity found the construction of Trump's wall to have a devastating impact on the ecosystem, with construction coming perilously close to the San Bernardino National Wildlife Refuge in Arizona, and an active migration corridor for the North American jaguar, as well as already damaging habitats in sites such as San Bernardino Slaughter Ranch. The survey also found unrestricted pumping of groundwater from local aquifers in order to produce concrete for the wall, which will have a destructive habitat on subterranean ecosystems as well as surface ones that are sustained by groundwater: https://biologicaldiversity.org/w/news/p...019-10-31/, https://www.azpm.org/p/home-articles-new...n-arizona/
On the positive side, the impeachment inquiry by the Democrat-controlled House of Representatives against Trump has began, so let's see whether or not the #impeachtrump movement can save San Bernardino and the jaguars that migrate between Mexico and the USA: https://edition.cnn.com/politics/live-ne...index.html San Bernadino, Arizona; credit: Ariana Brocious  *This image is copyright of its original author

At similar sizes, jaguar will outweight any puma or leopard. It is incredible jaguar is the dominant predator in America and have such a great variation is size. Jaguar in Guatemala/Mexico/Belize may be among the smallest ones (about 60 kg at max), but they are still the rulers of the Mayan world, the great "Balam". |
