Honestly, my T. hoehnelii are the last chameleons I bring inside in the winter because of cold temps and the last chameleons I bring inside because of hot temps in the summer. They really need night temperature drops, but they can handle temperature extremes quite well in both directions as long...

You can find them in a lot of areas in Kenya. Was there somewhere in particular you were planning to go? There are also many places in Uganda to find them. In both cases, you can even often find them in and around major cities. Chris

Yep, quite probably all of the above. There are also inherent issues with equitable access to scientific literature that disproportionately impacts researchers outside North America, Australia and Europe, but in this case most of the background articles (particularly on the tongue) are available...

They suffered from some of the same issues regarding a lack of appropriate background on what has already been done on the topic (part of why they failed to use appropriate terminology in the tongue paper), but they at least focused on comparing different age groups of the same species, so they...

Not sure, but I would guess so. The author of that study has published other SEM studies on Chamaeleo chamaeleon skin, for instance, so it is possible some of the same specimens were saved and used for these and other studies. In my lab I save the remaining tissue of specimens I use for studies...

Yep, except in the Nile delta you also find C. africanus coming north with the Nile to the coast, which is why you can also find them in Cairo. They seem to be restricted to that area, however in the northern part of the country. Chris

If we are talking about the Sidi-Barani on the northwest Mediterranean coast of Egypt, that would be Chamaeleo chamaeleon. If there is another Sidi-Barani in south Egypt, that would have to be C. africanus. So either way they only would have compared two species and many of the differences they...

Absolutely, and its nice that you do! It can be difficult to critically analyze studies though if you aren't a specialist, so when I see one that I don't think is a good study, I try to chime in so others can see some of those issues with it. Chris

Unfortunately, when we graphed the measurements of those 145 specimens, on average these differences held true, but there is a considerable amount of overlap in the sexes in their cranial dimensions at all but the largest of specimens (>130mm SVL), and that overlap exceeds 50% of individuals...

Ugh, this is one of those studies that should have never made it through peer review. Having studied the chameleon tongue for my dissertation, I was shocked to see this published. There are a ton of issues with the authors using completely incorrect terminology for the tongue and hyoid apparatus...

Its worth noting that the differences in casque size increase with body size, but there is a large range of moderate to small adult body sizes where these casque dimension differences are much less pronounced and even overlap. I performed field work on Chamaeleo chamaeleon in 2017 in Spain where...

Distinguishing juveniles from adults is difficult from photographs. The best method for this species would be based on body length (Snout-Vent Length), but this is obviously difficult from photographs. After viewing enough images of this species, you could probably start to gauge juvenile vs...

There has been initial community workshops run by the NGO Biodiversity Inventory for Conservation (https://binco.eu/), and a draft Action Plan for the species is in development. We are hoping that a larger NGO with more resources may also show interest in becoming involved, as that type of...

Hi Everyone, In 2014 the IUCN/SSC Chameleon Specialist Group (CSG) ran a crowdfunding campaign through Rockethub.com to perform a rapid assessment of the status of Rhampholeon chapmanorum, the most range restricted chameleon. This crowdfunding was supported in no small part by donations from...

Unfortunately the case with F. pardalis needing to be split into different species is far from clear cut, and there is not agreement on whether there is evidence yet to support doing so. With regard to the referenced paper, there was a lot more hype about the new species suggestion of this paper...
