The northern Bahamian rock iguana (Cyclura cychlura) is a species of

Bahamas. Its status on the IUCN Red List is vulnerable, with a wild population of less than 5,000 animals.[1]

Taxonomy

It was first described as a new species, Iguana cychlura, by Georges Cuvier in 1829.[1]

Mitochondrial DNA analysis by biologist Catherine Malone found its closest relatives to be Cyclura nubila on Cuba, and C. lewisi on Grand Cayman. According to her C. lewisi, C. nubila and C. cychlura had diverged almost as much as each other, although she only used a single locus and a very small sample set of each species.[3] According to a 2005 article in the magazine New Scientist C. lewisi may have diverged from C. nubila some 3 million years ago.[4]

There are three recognised

phylogenetically distinct from C. c. figginisi and C. c. inornata, she found these two populations were indistinct genetically and should likely be synonymised.[3]

Description

This species, like other species of Cyclura, is

pheromones.[6][7]

Distribution

This species only occurs in the southwestern

Andros Island and the Exuma islands.[1]

Ecology (Habitat)

It lives in tropical dry forest, pine barrens, coastal coppice, mangrove and beach strand

herbivorous. It is ground-dwelling, although juveniles often climb into branches in the morning to bask and feed.[1]

Conservation

Status

In 2004 the

IUCN assessed the species as a whole to be "vulnerable", although each of the three subspecies were assessed as endangered. The current global population of all three subspecies was estimated at less than 5,000 members and was thought to be declining. The population had decreased by at least 50% over the last 60 years.[1]

Causes of decline

In 2004 the IUCN listed the main threats to this lizard depended on the islands where the different subspecies came from; with the Andros Island population to be threatened by logging, infrastructure development, feral animals and fires set for agricultural or crab-hunting reasons. The populations from the Exumas were imperilled due to feral animals (goats), fires caused by tourists, and rapid private land acquisition (primarily for tourism purposes). Development, fire and feral animals had caused a reduction in area of suitable habitat of at least 20% over the previous 30 years. Feral animals which pose a threat to the iguanas are cats, dogs, hogs and goats.

Department of Agriculture who stated iguanas were still sometimes hunted and eaten, albeit rarely.[8]
