Another ‘traditional’ conference in Boppard am Rhein is on the programme for 2025. We have set the date for 16 to 18 May, so please keep this weekend free. We are currently working intensively on an exciting programme of travel reports, terraristics and scientific contributions.
Two Veiled Chameleons arrived at the reptile rescue centre in Munich yesterday. Both animals were confiscated and will not be returned to their original owners, so they will probably be released for rehoming shortly. They are two adult females who so far appear to be healthy. The results of the blood check-up and the quarantine at the rescue centre are still pending. However, anyone who is already interested in the two or one of the females is welcome to contact the rescue centre now. A questionnaire for interested parties can be found on their website.

On Tuesday, 01 October 2024, Rainer Dolch will give an exciting lecture at Frankfurt Zoo. Rainer Dolch has been working for the Mitsinjo Association in the eastern highlands of Madagascar for years, so he will be giving a first-hand report.
As a remnant of the ancient continent of Gondwana, Madagascar has been isolated in the Indian Ocean for more than a hundred million years. Due to the long period of isolation, evolution has gone its own way here and has produced a unique animal and plant world.
These include the lemurs, which comprise more than a hundred species, endemic predators such as the mongoose-like vontsiras and the puma-like fossas, as well as representatives of the tanreks – a group of mammals related to elephants and aardvarks – reminiscent of hedgehogs and shrews. Madagascar’s extinct megafauna also included several species of hippopotamus and giant lemurs as well as the giant ratite Aepyornis. The island’s animal world that still exists today is also massively threatened with extinction due to human influence. In his lecture, Rainer Dolch presents approaches for the urgently needed protection of this unique living world.

There are tiny chameleons in many places in Madagascar, including the smallest in the world. Now another tiny terrestrial chameleon has been described by Malagasy and German scientists: Brookesia nofy.
Brookesia nofy lives in a small remnant of lowland rainforest on the central east coast of Madagascar, in the Akanin’ny Nofy reserve. It probably also occurs in the neighbouring Vohibola reserve. The new species is related to Brookesia ramanantsoai, which occurs in the eastern highlands and not quite as close to the coast. Madagascar’s lowland rainforests are extremely threatened by deforestation. It is therefore all the better that this small chameleon already lives in two protected areas. Incidentally, the name nofy is the Malagasy word for dream and is therefore appropriate in two respects: firstly, because it was found in the ‘nest of dreams’ and secondly, because it lives in its own protected area, thus ensuring its survival for the time being.

The 21.6 km² Tlemcen Hunting Reserve is located in the north of Algeria, in the province of the same name. The climate is Mediterranean, the province borders the Alborán Sea (the westernmost part of the Mediterranean Sea) and lies directly opposite south-east Spain. The reserve is located around 26 kilometres southwest of the city of Tlemcen, the second largest city in Algeria, and spans the highest areas of the Tlemcen Mountains.
A local veterinarian and biologist recently carried out a survey study of the animals currently found in the reserve. In order to investigate the herpetofauna, manual searches or traps were set along measured transects. Chamaeleo chamaeleon was found several times during the study.

For some time now, there have been various programmes and algorithms that can make various predictions about how many species in a country or region could be threatened with extinction in the future based on given data. Until now, this has always required a whole series of locations and data for the respective animal species as a basis. However, these are often not available for rare species.
Italian scientists have now developed an algorithm called ENphylo, which can make predictions from just two observations per species. It was tested in parallel to conventional algorithms on a model with 56 chameleon species from Madagascar. The occurrence and locations of the chameleons were taken from the Global Biodiversity Information Facility. Various scenarios of climate change and progressive changes in land use were modelled using CHELSA and other databases for the period between 2071 and 2100. For each of the chameleon species, 45 modelled predictions were calculated in the study.hnet.
As a result, the scientists predict a habitat loss of over 90% for the species Brookesia decaryi, Brookesia brunoi, Calumma globifer, Brookesia desperata, Brookesia karchei, Brookesia micra, Brookesia tristis, Calumma amber, Calumma guibei, Calumma ambreense, Calumma nasutum, Calumma fallax, Calumma peltierorum, Calumma boettgeri, Furcifer petteri and Furcifer willsii. As a result, these species would be directly threatened with extinction by 2100 due to climate change and changes in land use in Madagascar. The greatest area losses in potential habitats are expected in the dry forests of the west and north-west and the lowland rainforests of the east coast. The potential habitat loss is also expected to affect species that only occur in a very small distribution area but are very common there, such as Brookesia tuberculata.
An increasing development of the habitat is only assumed for Furcifer oustaleti, Furcifer rhinoceratus, Calumma parsonii (unfortunately without indication of the subspecies), Calumma oshaughnessyi, Calumma crypticum, Calumma brevicorne and Brookesia supericilaris. According to the various calculation models, Madagascar could lose between eight and eleven chameleon species by the year 2100.

In Sierra Leone in West Africa, animal parts are still used in traditional medicine today. Two scientists from the University of Nala have now investigated exactly which ones and what they are used for.
The study was conducted in the chiefdoms of Kowa and Dasse between March and July 2023. Around 24,000 inhabitants live here, almost all of them farmers. Both areas are located in the Moyamba region in eastern Sierra Leone and are sparsely populated with the exception of four urban regions. The scientists interviewed 40 people and visited the patients they were treating. The interviewees included herbalists, traditional healers, fetish priests and obstetricians selected by the local population. People familiar with the area were asked about the fauna present. The animal parts used were photographed and sampled as far as possible.
As many as 17 of the interviewees had attended secondary school, while 17 others had received no schooling at all. All of them stated that they had learnt the healing methods used from their ancestors. 30 of the 40 interviewees made their living from traditional medicine and had been practising for around 30 years. A few even stated that they earned between $ 2120 and $ 4230 per year (the average for an employee in Sierra Leone is $ 2900 per year). Forty-five animal species were used for medicinal purposes, and 40 diseases were named as indications. The most frequently used animals, around a third, were reptiles, followed directly by amphibians, snails and mammals. Primates alone accounted for 10% of the animals used.
Chamaeleo gracilis was mentioned eighteen times during the interviews as a potential remedy. It is locally called ‘duqui’. Its skin, muscle parts and intestines are said to improve memory. It is also used for various mystical purposes. Most parts are eaten cooked.

AG member David Prötzel has successfully incubated and hatched a clutch of Furcifer viridis. Congratulations!
Furcifer viridis is a small species of chameleon found in western Madagascar. It was long thought that the species belonged to the carpet chameleon Furcifer lateralis – but since 2012 it has been clear that it is a separate species. David incubated the eggs for around 50 days at 20-22°C (room temperature), then a further 50 days at 24-25°C in an incubator. From day 100 until hatching, the eggs were at 28 to 29°C. The total incubation period was 142 days. David used fine vermiculite as a substrate, which was moistened once.
Regina Liebel will give a detailed presentation about a great trip to Namibia on July 5, 2024 in Bergkamen near Dortmund. After the European Championship match, of course ;) .

The DGHT’s digital regulars’ table was launched this year. This platform is ideal for all those who prefer to watch lectures and exchange ideas with other reptile keepers from the comfort of their sofa, but don’t necessarily want to travel far to do so. On Thursday, 27 June 2024, the topic will be “Enrichment for reptiles”.
This term refers to various ways of making the lives of animals in human hands more interesting. There are different forms of enrichment. The best known are certainly the different ways of obtaining food through toys, which are often seen with great apes, bears or big cats in zoos, for example. However, enrichment is also possible and highly interesting for reptiles. Tobias Machts will introduce the topic and show how it works with reptiles. Please register by e-mail to digitaler-stammtisch@dght.de.
