Regardless I think it’s safe to say that Guates jag was also taken over the curves. I’m assuming Adriano was measured in a straight line since Crawshaw was there as well, so that needs to be noted since Joker was over the curves. Should also be specified in regards to the lions for comparison. Also she kept the tail length the same and just increased the body length which may or may not be the case.

Lilian told me that they made changes in regards to the people allowed to take measurements to allow only the most experienced to take them. Joker having a very similar BL to the lioness makes complete sense given the similar weight, and the lions are not specified as being taken between pegs either. Joker may have in fact been heavier than the lioness in the absolutes.

Joker may have in fact been heavier than the lioness in the absolutes. He was 100% measured over the curves both times and Lillian was there for both captures as well. In regards to the Lions, they’re not specified for any protocol but you’d need to know which one was used to accurately compare. Generally speaking, female Lions/Tigers will still be larger in frame but Jaguars dense bodies allows them attain equal weights at times.

They are "over the curves", from the frontal teeth (not the nose) to the tip of the tail, following all the curves of the back. In straight line, these animals should be shorter by a significative margin, even if compared with other cats measured over curves, that take the nose as initial point of measurement.

Is possible, as there is no indication about the measurement method, only that was in the flesh. Sadly there are no more details about the specimen. I have no data about the difference between the "straight line" and "over curves!" in jaguars, but if we follow the data from Indian leopards (between 8 - 12 cm), the big jaguar reported by Nelson and Goldman probably measured as large as the largest jaguar reported by De Almeida.

Jaguars' bauplan is on a bulkness and robustness level that gives us no wonders why pound for pound they're unmatchable by any living felid in terms of robusity.
It's also to note that Lilian said nothing about the protocol on the server and capture.
And not all Jaguars are short framed, Joker may not be as tall but be can be very long in the body just like a lioness of similar body. Like @GuateGojira said, the lions were taken over curves in an even more dramatic matter so the comparison is perfectly reasonable assuming Joker was also taken over curves on his second capture. With Adriano being the only cat in the chart likely taken between pegs, thus undersizing him in comparison.

He was also the one that got us all of Jokers specific measurements and the protocol they use.

I'm going to compare the largest skull shown which is a Chaco Male to an Almeida Skull which will give us an idea of it's size. Chaco Male had a skull length of 11.96 inches x 8.38'' which is a total score of 20.34'' a comparable skull from Almeida would be either Thornton Snider's male that had a total score of 20.31'' and a weight of 101kg's or Dave Lauzen's who had a total score of 20.37'' and a weight of 112kg. Safe to assume the Chaco Male was a big Jag, comparable to the Pantanal Jaguars. 
It doesn't surprise me the Chaco jaguar matching the Pantanal skull, its just like the Cerrado jags, they overlap with the Pantanal and Porto Primavera ones not only in weight and dimensions but also they are very similar in size to those from Chaco. My guess is also the overlapping absolutely occurs on the skull department, if only we had measurements of Cerrado specimens. but we already have a small taste of it.
Left: Adult Pantanal male jag skull Right: Adult Cerrado male Jag skull (Tiago male) As you all know both were killed in territorial intraespecific fight to death. That Cerrado jag skull is huge, in 2020 Pckts made an estimation on the skull size and the result was really of a big specimen (as Tiago really is).  *This image is copyright of its original author Regarding Adriano's measure I just rechecked my email again from back then (when I got Adriano's measurements with Dr. Fernando Tortato) as you all already know he said to me ''We usually use a malleable measuring tape that involves the animal's body''. BUT there's something else he said in the end that I didn't pay attention back then (too excited focused on Adriano's size lol) in addition he said ''I don't remember exactly which tape we used in 2012 to capture Teo.'' As you can see bellow not only can we see which measuring tape was used but it was on the hands of the master Dr. Crawshaw. Obviously this could mean anything but there is good chances of Adriano/Teo/M11 have been measured the correct way.  *This image is copyright of its original author During my conversations with Dr. Peter Crawshaw on a topic about girth dimensions (as Head Girth is my favorite measurement) I even mentioned to him there was a male jaguar named Adriano of 130 kg that was 85 cm tall and big head circumference captured by Fernando Tortato and was measured over the curves (due to the melleable tape Panthera usually use). But the thing is, Panthera team calls Adriano as both ''M11 and Teo''. Rafael Hoogesteijn in our conversation also referred that jaguar to me as ''Tel''. Back then I didn't know Dr. Crawshaw was involved in Adriano (Tel, M11) capture. what a coincidence, If I used the name ''Teo or M11'' instead of ''Adriano'' while talking to Dr. Crawshaw I could've gotten more detailed information, if only I knew it in time, sadly.

In the wild, males are usually larger than females. Of the jaguars monitored by @oncafari at @caimanpantanal, males are about 37% heavier than females, weighing over 140 kg. Tupã (photo), despite appearing to be a giant guy (and in fact he is), is comparatively "small", weighing 108 kg. (07-11-2020, 06:59 PM)Dark Jaguar Wrote: 100kg Cerrado male from PN GSV.

Hi @Dark Jaguar I noticed this comment on Carnivora accusing you and the other people involved in the collection of the data of weights for Pantanal jaguars of supposedly lying.
I know the tables are reliable and complete but I think it's fair for you to at least have a say against this accusations since it's unfair for others to spread lies about your tables in forums where you aren't active. I believe @peter was happy with the tables since this was a project started here at Wildfact. Here is the post in question https://carnivora.net/leopard-v-jaguares...ml#p214159 let me know what you think |
