JAGUAR TIERS DIVIDED BY ECOTYPES

I've made this comparative image as a guideline of jaguar morphology and groupings based on the biome they inhabit. I've seen many people confusing biomes and jaguars from different places, or grouping populations in size classes with other populations that don't belong together, hopefully this will help.

Comments:

• The SH of jaguars from tier B is taken from one male of 110 kg captured in Porto Primavera, a seasonally flooded area between the Cerrado and At Forest that doesn't belong to either eco-region. In theory, this area would be placed in tier A but since it is so small and by now it has been completely lost due to anthropogenic factors I'm basing the maximum SH recorded in this area for jaguars from tier B who are the closest in proximity and similar maximum weight (P. Crawshaw).
• Jaguars from the Yungas do not have any recorded weight so far, they are placed under tier C due to them belonging to a similar biome as the other eco-regions, but based on estimates from the team of Red Yaguarete, these jaguars could likely be slightly larger than those form tier C in averages and maximums thanks to the preservation of their habitat.
• Maximum SH estimates for tiers C to E follow the same statistical trend as those from tier A.
