Calumma roaloko : a little-known species
A study of the distribution, microclimatic preferences and habitats of Calumma roaloko in the forests of eastern Madagascar
First described scientifically in 2018, Calumma roaloko is a small chameleon endemic to the rainforests of eastern Madagascar. Its geographical distribution, ecological requirements and sensitivity to habitat disturbance are still not sufficiently understood.
In the face of the degradation and fragmentation of Madagascar’s forests, improving our understanding of this species is crucial for assessing its vulnerability and guiding conservation efforts.
A project being carried out in Iaroka and Maromizaha
Caméléon Centre Conservation is developing a research programme focusing on Calumma roaloko in the Iaroka Forest and the Maromizaha Reserve, within the Ankeniheny-Zahamena forest corridor.
Building on data already collected by CCC students at these two sites, this project aims to deepen our understanding of the ecology and distribution of this species.
The research is structured around three complementary objectives:
-
To clarify its geographical distribution by documenting areas of occurrence, altitudes frequented and its distribution across the two forest massifs.
-
To study its microclimatic preferences by analysing the temperature and humidity conditions associated with the sightings, as well as the characteristics of the microhabitats it uses.
-
To gain a better understanding of its habitat requirements by studying its presence in different forest environments and its potential sensitivity to environmental disturbances.
The results will provide a better understanding of the ecological conditions necessary for the presence of Calumma roaloko and help identify habitats that are important for its conservation. The scientific data produced will also contribute to improving knowledge of its conservation status, particularly in the context of the IUCN’s work on the assessment of threatened species.
