After a whole six new species of the genus Rhampholeon were described in Tanzania at the end of last year, Mongabay devotes a detailed article to the topic.
Two years late, but apparently, the Frankfurter Rundschau has now noticed the rediscovery of Furcifer voeltzkowi in Madagascar, too.
Heute ist ein netter Artikel über Dreihornchamäleons in der Frankfurter Allgemeinen Zeitung erschienen. Hier könnt ihr ihn lesen.
Influence of UV-B on growthShort messages Science
An interesting husbandry experience from the USA was presented in a short note in the Herpetological Review. Twelve carpet chameleon hatchlings (Furcifer lateralis) from the same clutch were divided into four groups of three animals each. During the first ten weeks after hatching, two groups were provided with a daily UV index of up to 3 for 12 h, the other two groups with a UV index of up to 7. Reptisun 5.0 was used to achieve the different UV indices. Measurements were taken with the Solarmeter 6.5. The chameleons were allowed to avoid UVI up to 0. After six, eight and ten weeks, the carpet chameleons were measured and weighed. It was noticed that in weeks 6 and 10, the groups with the lower UV index were up to 25% heavier than the comparison groups.
The two authors conclude that higher UV indices during rearing in the first weeks could lead to slower growth rates in carpet chameleons. This would correspond to the observation in nature that young animals “sunbathe” rather rarely and stay more hidden in the bushes. Due to the small group of test subjects and mixed groups instead of individual keeping, you must still be cautious with conclusions here. In addition, it is unfortunately still largely unexplored whether and how chameleons can regulate their vitamin D3 regulation in artificial light compared to natural sunlight. Nevertheless, it is a very interesting approach that is certainly worth pursuing.

Save the date: Conference 2023 / Call for speakersShort messages
For the first time in the history of the AG Chamäleons, the date for the next meeting was found by online voting this year. An astonishing number of chameleon enthusiasts took part. As a result, the next meeting date will be 05 to 07 May 2023. So please mark this date in your calendar already now!
At the same time, we would like to invite you to submit planned presentations to email@example.com. We are looking for reports on common or rarer species, breeding reports, notes from everyday life with chameleons, travel reports to chameleon habitats, information on diseases, and also results from research, taxonomy, new discoveries or other exciting areas. If you would like to give a talk, you do not necessarily have to be a member of the AG Chamäleons or the DGHT. We are looking forward to a colourful variety of presentations!
