Life histories, demographies and population dynamics of three sympatric chameleon species (Furcifer spp.) from western Madagascar
- Biology, Environmental ScienceAmphibia-Reptilia
This study suggests the co-existence of three different life histories with seasonal adjustment that might be related to the partitioning of overall food availability and contributes valuable life history data on enigmatic chameleon species.
Rediscovery, conservation status and genetic relationships of the Malagasy chameleon Furcifer voeltzkowi
- Biology, Environmental Science
DNA sequences of the nuclear CMOS gene and two mitochondrial markers confirm that F. voeltzkowi is a distinct species and sister to F. labordi and suggest that it qualifies as Endangered B1ab(iii) under the IUCN Red List Criteria as its populations are expected to be severely fragmented, and there is continuing decline in the extent and quality of its habitat.
Sex-specific movement ecology of the shortest-lived tetrapod during the mating season
- Environmental ScienceScientific reports
Sex-specific reproductive strategies are shaped by the distribution of potential mates in space and time. Labord’s chameleon (Furcifer labordi) from southwestern Madagascar is the shortest-lived…
Adana (Türkiye)’dan Toplanan Chamaeleo chamaeleon (Linnaeus, 1758) (Lacertilia: Chamaeleonidae) Örneklerinin Yaş ve Vücut Büyüklüğü
- BiologyCommagene Journal of Biology
Results obtained here indicate that C. chamaeleon is one of the short-living lizard species when compared to other lizards, and there was no significant correlation between the SVL and age.

A unique life history among tetrapods: An annual chameleon living mostly as an egg
- BiologyProceedings of the National Academy of Sciences
The discovery of a remarkable annual tetrapod from the arid southwest of Madagascar: the chameleon Furcifer labordi, with a posthatching life span of just 4–5 months is reported, suggesting that the notorious rapid death of chameleons in captivity may, for some species, actually represent the natural adult life span.
Life history traits, age profile, and conservation of the panther chameleon, Furcifer pardalis (Cuvier 1829), at Nosy Be, NW Madagascar
- Environmental Science
The life history traits, high fecundity and short life span indicate that the current collecting rate does not affect the abundance of F. pardalis, and measures of chameleon conservation at Nosy Be should consider the preservation of the anthropogenic forest band.
Rivaling the World's Smallest Reptiles: Discovery of Miniaturized and Microendemic New Species of Leaf Chameleons (Brookesia) from Northern Madagascar
- BiologyPloS one
The newly discovered dwarf chameleon species represent striking cases of miniaturization and microendemism and suggest the possibility of a range size-body size relationship in Malagasy reptiles.
Age estimation by phalangeal skeletochronology of Caretta caretta from the Mediterranean Sea
- Environmental Science
Longevity was often greater than 20 years in individuals with CCL over 50 cm and the oldest individual had 83 cm of CCL and was approximately 32–37 years old.
Large-scale phylogeny of chameleons suggests African origins and Eocene diversification
- Environmental ScienceProceedings of the Royal Society B: Biological Sciences
It is suggested that contraction and fragmentation of the Pan-African forest coupled to an increase in open habitats (savannah, grassland, heathland), since the Oligocene played a key role in diversification of this group through vicariance.

Eastward from Africa: palaeocurrent-mediated chameleon dispersal to the Seychelles islands
- Environmental ScienceBiology Letters
Divergence dating and biogeographic analyses indicate an origin by transoceanic dispersal from Africa to the Seychelles in the Eocene–Oligocene, providing the first such well-documented example and supporting novel palaeocurrent reconstructions.
Forest disturbance and river proximity influence chameleon abundance in Madagascar

Chameleon radiation by oceanic dispersal
- Environmental Science, GeographyNature
Support for a phylogeny and area cladogram that does not fit a simple vicariant history for chameleons is shown, using molecular and morphological evidence for 52 chameleon taxa.
Slow but tenacious: an analysis of running and gripping performance in chameleons
- Environmental ScienceJournal of Experimental Biology
The results suggest that previously documented trade-offs may have been caused by differences between clades rather than by design conflicts between running and gripping per se, and that habitat drives the evolution of morphology and performance but that some of these effects are specific to each clade.
