Anolis marmoratus
Anolis marmoratus·Dactyloidae
Anolis marmoratus, commonly known as the leopard anole or Guadeloupe anole, is a lizard species endemic to the islands of Guadeloupe in the Caribbean. It is characterized by extreme variability in appearance, with populations on Basse-Terre and Grande-Terre islands exhibiting distinct differences that have led to the recognition of numerous subspecies, though intergradation is extensive.

About Anolis marmoratus
Anolis marmoratus, widely recognized as the leopard anole or Guadeloupe anole, is a distinct lizard species native to the Guadeloupe archipelago in the Caribbean's Lesser Antilles. This species is notably characterized by its considerable variability in physical appearance, a trait that has led to extensive scientific discussion and the reclassification of several former subspecies into their own distinct species.
Taxonomy and Variability
The leopard anole's taxonomic history includes the elevation of five former subspecies—A. ferreus, A. terraealtae, A. kahouannensis, A. chrysops, and A. desiradei—to full species status. Despite the recognition of current subspecies, primarily distributed across Basse-Terre and Grande-Terre islands, there is significant intergradation between them. This extensive blending, coupled with extreme individual and regional variations in appearance, has prompted questions regarding the strict validity of these subspecies. Factors such as human-induced habitat changes, which facilitate greater population contact, and deliberate translocations may have enhanced this intergradation.
Genetic Insights
Genetic studies on Anolis marmoratus have provided further insight into its population dynamics. These studies indicate a lack of strong assortative mating among the different populations, even though these groups have diverged visually and genetically over approximately 650,000 years. This finding suggests that despite observable differences, reproductive isolation is not strictly maintained at the genetic level between these historically separated populations.

Frequently Asked Questions
What are the common names for Anolis marmoratus?
Anolis marmoratus is commonly known as the leopard anole, the Guadeloupe anole, or the Guadeloupean anole. These names reflect its distinctive markings and its native geographic location.
Where is Anolis marmoratus found?
This species is endemic to the islands of Guadeloupe, which are part of the Lesser Antilles in the Caribbean. Various subspecies are distributed across different parts of the archipelago.
Why is Anolis marmoratus known for its variability?
Anolis marmoratus exhibits extreme variability in its appearance, both between different regions and among individuals within the same region. This variation is so significant that the validity of its subspecies has been questioned due to extensive intergradation.
Have any subspecies of Anolis marmoratus been recognized as separate species?
Yes, five former subspecies of Anolis marmoratus have been elevated to species status. These include A. ferreus, A. terraealtae, A. kahouannensis, A. chrysops, and A. desiradei.
What do genetic studies say about Anolis marmoratus populations?
Genetic studies have confirmed that despite distinct visual differences and a separation of about 650,000 years, strong assortative mating between different populations of Anolis marmoratus does not exist.
