Presentation in Basel about the Comoros

by Alex Negro Reiseberichte Live lectures

Dr Oliver Hawlitschek from the University of Zurich will be giving a great lecture on the Comoros on Wednesday, 5 March 2025 in Basel (Switzerland). The Comoros are a group of four volcanic islands in the Western Indian Ocean. Compared to similar oceanic archipelagos such as Hawai’i and the Galápagos, however, they are little known globally and little scientifically researched. The fauna is characterised by a large number of endemic species. Over the past 15 years, Oliver has studied the taxonomy, biogeography and ecology of the reptiles and amphibians living there and has been involved in numerous conservation projects. He will be presenting the results of this work on this evening – it’s sure to be very exciting!

Namaqua chameleons discovered in Namibe (Angola)

Namaqua chameleons discovered in Namibe (Angola)

by Alex Negro Verbreitung Science

Western Angola has increasingly become the focus of herpetologists in recent years. However, the reptile population of the Iona National Park on the border with Namibia still raises some questions. Whilst searching for the dwarf puff adder Bitis peringueyi, an international research team also found Chamaeleo namaquensis. The survey of reptile populations was carried out in the coastal area, in the sand sea and in the shifting sand dunes of the gravel plains.

A total of 27 reptile species were discovered – although the dwarf puff adder was not among them. Chamaeleo namaquensis was found along the EN100 road about 50 kilometres south of Moçamedes. A second site was found around 10 km north of Salondjmba, the entrance to the Iona National Park in Ponta Albina.

Utilisation of flap-necked chameleons at urban markets in South Africa

Utilisation of flap-necked chameleons at urban markets in South Africa

by Alex Negro Science

Scientists from the African Amphibian Conservation Research Group have analysed the existing literature on the subject. Fortunate M. Phaka also visited six municipal markets in Durban, Johannesburg, Petermaritzburg, Polokwane and Pretoria. At the markets, he searched for amphibians and reptiles sold for medicinal purposes and the names given to them by the vendors. He was able to interview 11 traditional health practitioners in Limpopo, Gauteng and KwaZulu-Natal in detail, from nine of whom he was allowed to take samples of the amphibians and reptiles sold for species identification.

In total, 33 species of reptiles and one species of amphibian used for traditional medicine were identified. Nine of these were found and identified on site during the market visits. The traditional healers interviewed stated that they had either hunted the animal parts themselves, bought them from hunters or taken them from roadkill. Fat and internal organs are removed, the carcasses are rubbed with ash or salt and dried in the sun. Usually, the healers’ customers do not buy complete carcasses, but only small parts of the reptiles on offer. Of the 111 animal samples taken, sufficient DNA to identify the species was obtained from 90 of them. 23% of the samples tested were incorrectly named by the healers.

Chamaeleo dilepis was among the reptile species utilised. No complete chameleon could be found at the markets visited. At the Warwick Muthi Market in KwaZulu-Natal, however, several reptile parts were sampled which, according to DNA comparisons, came from lobed chameleons. Chameleons in general were not identified to species level by the healers. The IsiZulu word unwabu stands for any chameleon.

Barcoding and traditional health practitioner perspectives are informative to monitor and conserve frogs and reptiles traded for traditional medicine in urban South Africa

Panther chameleon disposed of at recycling centre

Panther chameleon disposed of at recycling centre

by Alex Negro Abzugeben General topics

A panther chameleon in Bavaria owes its life to a lucky coincidence. An irresponsible owner abandoned the animal in a cold polystyrene box at the Eichenau recycling centre. An attentive passer-by, who was taking cardboxes to the recycling centre himself, heard scratching noises and opened the lonesome box. The reptile rescue centre in Munich was informed immediately, which took in the hypothermic chameleon and is now looking after it. The animal had obviously not received any medical care recently.

It is to be hoped that the original owner can be identified and faces an appropriate penalty. In some cases, the abandonment of animals even constitutes a criminal offence – in this case, the reptile was likely to die. ‘Lucifer’, as the panther chameleon was named, was simply lucky – and will soon be hoping for a great new home with a greater sense of responsibility. Anyone interested can contact the rescue centre.

Addendum 03.03.2025: The case actually played out a little differently. The alleged finder of the abandoned panther chameleon has since turned out to be the original owner of the animal. A report has been filed.

Presentation in Frankfurt about feeders

Presentation in Frankfurt about feeders

by Alex Negro Book publications Live lectures

To kick off its 2025 lecture series, the regional group Saar-Pfalz has invited two speakers for Friday, 07 February 2025. The two successful terrarium keepers Walter Wiest and Stefan Greff will be talking about their book project and their efficient feeders breeding programme, which was only published by Natur und Tier-Verlag at the end of last year. High-quality feeders are essential for the successful keeping and breeding of predatory freshwater fish, amphibians, reptiles, invertebrates, small mammals and insectivorous birds. Variety is essential for a healthy diet. The best way to ensure such a varied diet for the animals you keep is to breed invertebrates yourself. In their practical guidebook, which they will present to us this evening, the experienced breeders describe how this can be done without much effort and is also fun.

Chamaeleo gracilis in Nechisar (Ethiopia)

Chamaeleo gracilis in Nechisar (Ethiopia)

by Alex Negro Verbreitung Science

Over the last hundred years, humans have reduced Ethiopia’s forest cover from around 40% to just 2.36%. Despite this, little is still known about the country’s herpetological fauna in some places. Scientists from Egypt, the USA and Ethiopia recently carried out a survey study in a national park.

Necisar National Park is located in south-west Ethiopia on the line of the Great Rift Valley, more than 500 kilometres south of the capital Addis Ababa. Necisar covers an area of 514 square kilometres, bordered to the north and south by two lakes, to the east by the Amarao Mountains and to the west by the town of Arbaminch. Nechisar is very hot all year round with very little rainfall.

A total of two expeditions were carried out during the rainy season and two during the dry season. Transects with a total length of 290 km and a width of nine metres were covered, 230 km of which were in grassland and stony terrain, 60 km in the forest and along the lakeshore. In addition to manual searches with the naked eye, small pitfall traps and cover plates were used.

A total of 34 species of reptiles were found, including Chamaeleo gracilis. The species was discovered twice. Both chameleons were found near different rivers, one in the scrubland and one in the forest.

Presentation in Hamburg about Madagascar’s chameleons

Presentation in Hamburg about Madagascar’s chameleons

by Alex Negro Reiseberichte Live lectures

If that’s not an exciting and highly interesting start to the new lecture year! On Friday 10 January 2025, Falk Eckhardt, a long-standing member of the Chameleons Working Group, will be giving a detailed talk on the chameleons of Madagascar.

Hardly any other lizard family is as well known as the chameleons. This is mainly due to their many special features, such as their independently movable eyes, rapid colour change, sling tongue, pincer-like feet and prehensile tail. Madagascar is considered the centre of species diversity in this family. Almost half of all chameleon species, including the world’s smallest and largest species, live on this island. There are currently around 100 species on Madagascar, divided into four genera. Representatives of the two original genera Brookesia and Palleon are predominantly small, brownish in colour and usually stay close to the ground. Their ability to change colour is limited and their tail is rather short. The two other genera Calumma and Furcifer, on the other hand, show all the classic characteristics of the ‘typical’ chameleon.

In his lecture, Falk will discuss the distribution and lifestyle of Madagascan chameleons. Special attention will also be paid to the short lifespan of some species, which Falk has also worked with professionally over a longer period of time. The importance of chameleons in Malagasy culture will also be discussed. That really sounds like a wonderful chameleon evening!

What kills chameleons in zoos?

What kills chameleons in zoos?

by Alex Negro Tiermedizin Science

Scientists at the University of Veterinary Medicine Montréal (France) recently analysed the causes of death in chameleons kept in zoos between 2011 and 2022. The Zoological Information Management System (ZIMS) was used to search for zoos that currently keep chameleons or have kept them since 2011. Questionnaires were sent to a total of 245 zoos. The questionnaires asked about the number, species and sex of chameleons kept, as well as selected husbandry conditions (coolest and warmest temperatures, humidity, feeding) and dissection results.

Around 1000 chameleons of 36 different species are currently kept in zoos worldwide. 65 of the zoos surveyed took part in the study, 48 of which regularly carried out dissections on chameleons. However, only 29 of the participating zoos were able to provide dissection results. A total of 412 pathological findings from 14 different chameleon species were analysed. Among the species kept were Brookesia stumpffi, Brookesia superciliaris, chameleons of the genus Brookesia without species identification, Calumma parsonii, Chamaeleo calyptratus, Chamaeleo chamaeleon, Furcifer lateralis, Furcifer oustaleti, Furcifer pardalis, Rieppeleon brevicaudatus, Trioceros melleri, Trioceros montium and Trioceros quadricornis. Panther chameleons were kept most frequently (226 specimens).

The statistical analysis showed that most of the chameleons in the participating zoos died of infectious diseases (46.8%). Infectious diseases included septicaemia, but also inflammation of the oral cavity, lungs, liver, kidneys and intestines. Almost 20% of the infectious diseases were in the area of the oral cavity. The most common bacteria were Enterococcus and Pseudomonas. Among the fungi, Nannizziopsis including CANV, Fusarium and Metarhizium were represented. A good third of the necropsy reports also indicated parasitoses, with these occurring both as a cause of death and as an incidental finding. Coccidia and trematodes as well as various nematodes were often present. The second most common cause of death in the participating zoos was non-infectious kidney diseases (11.4%). This was closely followed by diseases of the reproductive tract, including egg loss and egg yolk coelomitis, which accounted for 10.7% of cases.

Contrary to the authors’ initial assumption, there was no correlation between the surveyed husbandry parameters in the cages and the incidence of kidney disease. Basically, there was a tendency towards an increased incidence of kidney disease in countries where the average humidity was generally lower.

Interested parties wanted for breeding project with Chamaeleo calyptratus calcarifer

Interested parties wanted for breeding project with Chamaeleo calyptratus calcarifer

by Alex Negro Abzugeben Projects

The larger subspecies of the Veiled Chameleon, Chamaeleo calyptratus calcarifer, from the Tihama on the Arabian Peninsula has received little attention in the herpetoculture hobby in recent years. It is therefore not surprising that notes on this subspecies are not particularly frequent in the current literature and that there is also a lack of husbandry and breeding reports. Sophie Obermaier, a member of AG Chamäleons from Berlin, would like to change this and breed the species in the long term. She herself has several adults of the species and already has over 50 eggs that are currently being incubated. Anyone who has had experience with the subspecies, would like to participate by keeping a few animals themselves or would like to take on young animals for scientific work is cordially invited to contact Sophie by email at chartar.0702@gmail.com.
