Nosy Hara: -12.244734, 49.012756

Nosy Hara is an island in front of a bay not far from Antsiranana (Diego Suarez) in the north of Madagascar. The island is about 3.2 km² large and consists mainly of karst rock, which covers the island in layers and resembles the Tsingys. Panther chameleons live here in the partly gigantic trees of the dry forest, which squeeze themselves everywhere on the island between the rocks. But they also use larger bushes. Even in the mangroves you can find an animal from time to time. Since Nosy Hara has been considered fady (taboo) by locals for decades, this locale of the panther chameleons could develop completely undisturbed. The entire island of Nosy Hara is a national park, but visitors are scarce. This is mainly due to the fact that Nosy Hara can only be reached by boat and there is neither running water nor electricity. So every supply (water, food, cooking facilities) has to be taken to the island, which means a considerable logistical as well as financial effort in Madagascar.

Appearance of the locale:

As a locale completely isolated from the mainland and other islands, Nosy Hara has developed very colourful and pretty panther chameleons. The males are green at rest, when excited yellow with dark, wine-red banding, while head and tail can be more red. On the head and throat there are usually turquoise blue or green accents. We have noticed so far that the male panther chameleons here have narrower (and therefore a higher number of) stripes than other locales.

It is illegal in Madagascar to take animals from protected areas or even national parks. Whoever finds this local form outside Madagascar can be sure that the chameleons were either exported illegally or that it is not this local form.

 

Table of weights

Gewichtstabelle Furcifer pardalis 2018

Since 2015 we have been measuring the weights of chameleons found in Madagascar, as far as the animals (and our scales) participate. So far there are only a few weights, in the long run an average weight in relation to the head-torso length (measured from the tip of the nose to the cloaca) for each species should be readable from as large a number of measurements as possible. It is important to know that all weights were measured towards the end of the rainy season (= best food supply), so they should be 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, it has so far turned out that there are no serious differences in the ratio of the KRL to weight between the individual local forms.

Die angegebenen Daten wurden von uns innerhalb mehrerer Jahre mit Thermo- und Hygrometern direkt an den Fundorten der Tiere gemessen und zusammengetragen. "Durchschnittliche Temperatur" bedeutet, dass die Werte eines gesamten Monats zu einem Durchschnittswert berechnet wurden, z.B. wurden alle gemessenen Minimalwerte eines Monats zu einem durchschnittlichen Minimalwert für Februar berechnet. Das bedeutet im Klartext, dass einzelne Spitzenwerte eines Tages deutlich höher oder niedriger als die durchschnittlichen Minimal- und Maximalwerte liegen können. Es ist also möglich, dass zwar das durchschnittliche Maximum bei 29 Grad liegt, es aber an einigen Tagen des Monats 33°C oder gar 35°C warm war.

Das Klima auf Nosy Hara ist ähnlich dem von Antsiranana (Diego Suarez) an der Küste: Es ist warm bis heiß, und die meiste Zeit des Jahres relativ trocken. Die Lage als Insel im Meer sorgt zeitweise für ein etwas feuchteres Klima, Niederschläge gibt es aber trotzdem vor allem in der Regenzeit.

Nachts sinken die Temperaturen nur wenig und sind immernoch sehr warm (beim Zelten schwitzt man noch bestens).

2019 UVI Nosy Hara

Die UVB-Daten wurden mit einem Solarmeter 6.5 im Frühjahr (April) zur höchsten Aktivitätszeit der Chamäleons gemessen. Gemessen wurden jeweils maximal für das Chamäleon zu erreichende Werte im Habitat.

Leider sind noch keine Bodentemperaturen für Nosy Hara verfügbar.

Habitat:

The dry forest of Nosy Hara nestles everywhere in the niches and gorges in the karst rock of the island. The ground is enormously rocky, the soil itself rather sandy. Where there are no rocks, there are many pebbles, some leaves and only in the wetter areas knee-high plants covering the ground. The panther chameleons on the island use both huge trees and large bushes as habitats, but usually do not leave the dry forest.
