Distribution of the locale Beramanja:
The small hut village Beramanja is located in northwest Madagascar in region Diana, exactly between the two cities Ambilobe and Ambanja along RN 6. The village is surrounded by several small rivers that isolate this habitat for panther chameleons. Unfortunately, the area is used for sapphire mining, so please do not walk around streets and villages nearby without a local, knowledgeable guide. Many places are privately owned and entering is strictly forbidden.
Appearance of the locale:
The males’ colours are sky blue with rust red stripes. Eyes, cheeks and corner of the mouth are yellow to bright green coloured. Partially they look strongly similar to some individuals from Ambanja.
Gewicht = weight in grams, Kopf-Rumpf-Länge = snout-vent-length in cm, Weibchen = females, Männchen = males
Since 2015 we have been measuring the weights of chameleons we have found in Madagascar, as far as the animals (and our scales) are participating. So far there are only a few weights, in the long term an average weight in relation to the snout-vent-length It is important to know that all weights were measured towards the end of the rainy season (= best food supply), so they are probably maximum weights in Madagascar. Triangular symbols in females do not mean pregnant, round symbols mean pregnant. In the case of Furcifer pardalis, contrary to our original assumption, there have been no serious differences in the ratio of SVL to the weight of the individual locales.
We have collected the data given above over several years with thermometers and hygrometers at the finding places of the chameleons. "Average temperature" means that values of a whole month have been calculated to one average value per month. For example all measured minimum temperature values of February have been calculated to one average minimum temperature for February. In plain language, this means single peak values of a day may be a little higher or lower than the average minimum and maximum temperatures. It is possible that a location has an average maximum temperature of 29°C, but one day during that month it had 33°C or even 35°C there.
Ambanja has warm temperatures around 25°C all year long. In sunny places, temperatures may rise above 30°C. At night, temperatures drop to 20°C, during dry season they may even fall slightly below to 18°C.
During rainy season, it rains daily and a lot, so humidity raises quickly. But the region remains green even during dry season. It may rain a lot less, but precipitaion is still regular. Additionally, the location between rivers cares for a steady water supply of trees and other plants.
We have measured UVB data with a Solarmeter 6.5 in spring (beginning of April) at the peak of activity of chameleons in Madagascar. We always measured the values that a chameleon could maximally reach in its habitat.
The panther chameleons of Beramanja live in open landscapes and secondary vegetation around the ramshackle huts of the village. Big old mango trees dominate the landscape. Additionally, this is the region where the cocoa and coffee plantations of Ambanja begin that also serve as habitat for panther chameleons. You can find the animals also in bushes and palms right at the edge of the street.
